Self-Diagnostics

If a diagnostic lamp illuminates during normal engine

operation, the system has identified a situation that is

not within the specification. Use the electronic service

tool to check the active diagnostic codes.

The electronic  control module has  some

self-diagnostic ability. When an electronic problem

with an input or an output is detected, a diagnostic

code is generated. This indicates the specific problem

with the circuitry.

The active diagnostic code should be investigated.

The cause of the problem should be corrected as

soon as possible. If the cause of the active diagnostic

code is repaired  and there is only one  active

diagnostic code, the diagnostic lamp will turn off.

A diagnostic code which represents a problem that

currently exists is called an active code.

A diagnostic code that is stored in memory is called

a logged code. Always service active codes prior to

servicing logged codes. Logged codes may indicate

intermittent problems.

Operation of the engine and  performance of the

engine can be limited  as a result of the  active

diagnostic code that is generated. Acceleration rates

may be significantly slower and power outputs may

be automatically reduced. Refer to Troubleshooting

, “Troubleshooting with a Diagnostic Code” for more

information on the relationship between each active

diagnostic code and the possible effect on engine

performance.

Logged codes may not  indicate that a repair is

needed. The problems may have been repaired since

the logging of the code. Logged codes may be helpful

to troubleshoot intermittent problems.

i02572812

i02784585

Engine Operation  with

Diagnostic Lamp

Intermittent Diagnostic Codes

The “DIAGNOSTIC” lamp is used to  indicate the

existence of an active fault.

If a diagnostic lamp illuminates during normal engine

operation and the diagnostic lamp shuts OFF,  an

intermittent fault may have occurred. If a fault has

occurred, the fault will be logged into the memory of

the Electronic Control Module (ECM).

A fault diagnostic code will remain active until  the

problem is repaired.

i02784192

Fault Logging

In most cases, it is not necessary to stop the engine

because of an intermittent  code. However, the

operator should retrieve the  logged fault codes

and the operator should reference the appropriate

information in order to identify the nature of the fault.

The operator should log any observation that could

have caused the lamp to light.

The system provides the capability of Fault Logging.

When the Electronic  Control Module (ECM)

generates an active diagnostic code, the code will

be logged in the memory of the ECM. The Perkins

electronic service tool can retrieve codes that have

been logged. The codes that have been logged can

be cleared with the Perkins electronic service tool.

The codes that have been logged  in the memory

of the ECM will be automatically cleared from  the

memory after 100 hours.

•  Low power

•  Limits of the engine speed

•  Excessive smoke, etc

This information can be useful to help troubleshoot

the situation. The information can also be used for

future reference. For more information on diagnostic

codes, refer to the Troubleshooting guide  for this

engine.

Before Starting Engine

Note: Do not adjust the engine speed control during

start-up. The electronic control module (ECM) will

control the engine speed during start-up.

Before the engine is started, perform the  required

daily maintenance  and any other  periodic

maintenance that is due. Refer  to the Operation

and Maintenance Manual, “Maintenance Interval

Schedule” for more information.

New engines

Prime the turbocharger. This can be achieved  by

cranking the engine briefly with no fuel.

•   Open the fuel supply valve (if equipped).

If necessary, stop a new engine  if an overspeed

condition occurs. If necessary, press the Emergency

Stop button.

NOTICE

All valves in the fuel return  line must be open before

and during engine operation to help prevent high fuel

pressure. High fuel pressure may cause filter housing

failure or other damage.

Starting the Engine

1.  Move the ignition switch to the ON position. If a

system fault is indicated, investigate the cause. If

necessary, use the Perkins electronic service tool.

If the engine has not been started for several weeks,

fuel may have drained from  the fuel system. Air

may have entered the filter housing. Also, when fuel

filters have been changed, some air pockets will be

trapped in the engine. In these instances, prime the

fuel system. Refer to the Operation and Maintenance

Manual, “Fuel System - Prime” for more information

on priming the fuel system.

2.  Push the start button or turn the keyswitch to the

START position in order to crank the engine.

3.  If the engine fails to start  within 30 seconds,

release the start button or the ignition switch. Wait

for 30 seconds in order to allow the starting motor

to cool before attempting to start the engine again.

Note: A system fault may  be indicated after the

engine is started. If this occurs the ECM has detected

a problem with the system. If  necessary, use the

Perkins Service Tool to investigate the problem.

Engine exhaust contains products of combustion

which may be harmful to your health. Always start

and operate  the engine  in a well  ventilated area

and, if in an enclosed area, vent the exhaust to the

outside.

Note: Oil pressure should rise within 15  seconds

after the engine starts. The engine electronic controls

monitor the engine oil  pressure. The electronic

controls will stop the engine if  the oil pressure is

below normal.

•  Do not start the engine or move any of the controls

if there is a “DO NOT OPERATE” warning tag or

similar warning tag attached to the start switch or

to the controls.

4.  When possible, allow the engine to run at no load

for approximately three minutes. Run the engine

at no load until the  water temperature gauge

has started to rise. Check all gauges during the

warm-up period.

•  Reset all of the shutoffs or alarm components (if

equipped).

•  Ensure that any equipment that is driven  by the

engine has been disengaged from the  engine.

Minimize electrical loads or remove any electrical

loads.

Cold Weather Starting

Note: The oil pressures and fuel pressures should

be in the normal range on the instrument panel. Do

not apply a load to the engine until the oil pressure

gauge indicates at least normal pressure. Inspect the

engine for leaks and/or unusual noises.

Do not use aerosol types of starting aids such as

ether. Such use could  result in an explosion and

personal injury.

Note: After the ECM has completed the cold mode,

cold mode cannot be enabled again until the ECM is

switched OFF.

The engine will start at  a temperature of −10 °C

(14 °F). The ability to start at temperatures  below

10 °C (50 °F) will improve by the use of  a cylinder

block coolant heater or a device  which heats the

crankcase oil. This will help to reduce white smoke

and misfires when the  engine is started in cold

weather.

Note: Do not attempt to restart the engine until the

engine has completely stopped.

After Starting Engine

Note: In temperatures from 0 to 60°C (32 to 140°F),

the warm-up time is approximately three minutes. In

temperatures below 0°C (32°F), additional warm-up

time may be required.

Note: Ensure that the self test  for the monitoring

system (if equipped) is completed before operating

the engine under load.

When the engine idles during warm-up, observe the

following conditions:

•  Check for any fluid or for any air leaks at idle rpm

and at one-half full rpm (no load on the  engine)

before operating the engine under load. This is not

possible in some applications.

•  Operate the engine at low idle until  all systems

achieve operating temperatures. Check all gauges

during the warm-up period.

Note: Gauge readings should be  observed and

the data should be recorded frequently  while the

engine is operating. Comparing the data over time

will help to determine  normal readings for each

gauge. Comparing data over time  will also help

detect abnormal operating developments. Significant

changes in the readings should be investigated.

Engine Operation

The efficiency of the  engine can affect the fuel

economy. Perkins design  and technology in

manufacturing provides maximum fuel efficiency in

all applications. Follow the recommended procedures

in order to attain optimum performance for the life

of the engine.

Correct operation and maintenance are key factors

in obtaining the maximum  life and economy of

the engine. If the directions in  the Operation and

Maintenance Manual are followed, costs can  be

minimized and engine service life can be maximized.

•  Avoid spilling fuel.

Gauge readings should be observed and the data

should be recorded frequently  while the engine

is operating. Comparing the  data over time will

help to determine normal readings for each gauge.

Comparing data over time  will also help detect

abnormal operating developments. Significant

changes in the readings should be investigated.

Fuel expands when the fuel is warmed up. The fuel

may overflow from the fuel tank. Inspect fuel lines for

leaks. Repair the fuel lines, as needed.

•  Be aware of the properties of the different fuels.

Use only the recommended fuels.

•  Avoid unnecessary operation at no load.

Shut off the engine instead of operating the engine

at no load for long periods of time.

•  Observe the service indicator for the air cleaner

frequently, if equipped. Keep  the air cleaner

elements clean.

•  Maintain a good electrical system.

One bad battery cell will overwork the alternator. This

will consume excess power and excess fuel.

•  Ensure that the belts are properly adjusted. The

belts should be in good condition.

•  Ensure that all of the connections of the hoses are

tight. The connections should not leak.

•  Ensure that the driven  equipment is in good

working order.

•  Cold engines consume excess fuel. Keep cooling

system components clean  and keep cooling

system components in good repair. Never operate

the engine without water temperature regulators.

All of these items will  help maintain operating

temperatures.

Manual Stop Procedure

Note: Before you check the engine oil, do not operate

the engine for at least 10 minutes in order to allow

the engine oil to return to the oil pan.

Stopping the Engine

•  Check the crankcase oil level. Maintain the oil level

between the “LOW” mark and the “HIGH” mark on

the oil level gauge.

NOTICE

Stopping  the engine  immediately  after it  has  been

working under load, can result in overheating and ac-

celerated wear of the engine components.

Note: Only use  oil that is  recommended in

this Operation and Maintenance Manual,  “Fluid

Recommendations”. Failure to use the recommended

oil may result in engine damage.

Avoid accelerating the engine prior to shutting it down.

Avoiding  hot  engine  shutdowns  will  maximize  tur-

bocharger shaft and bearing life.

•  If necessary, perform minor adjustments. Repair

any leaks and tighten any loose bolts.

•  Note the service hour meter  reading. Perform

the maintenance that is  in the Operation and

Maintenance Manual, “Maintenance Interval

Schedule”.

Note: Individual applications will  have different

control systems. Ensure that the shutoff procedures

are understood. Use the following general guidelines

in order to stop the engine.

•  Fill the fuel  tank in order  to help prevent

accumulation of moisture in the fuel. Do not overfill

the fuel tank.

1.  Remove the load from the engine.  Allow the

engine to run under no load conditions  for five

minutes in order to cool the engine.

•  Allow the engine to cool. Check the coolant level.

Maintain the cooling system at 13 mm (0.5 inch)

from the bottom of the pipe for filling.

2.  Stop the engine after the  cool down period

according to the shutoff system on the engine and

turn the ignition keyswitch to the OFF position.

If necessary, refer to the  instructions that are

provided by the OEM.

Note: Only use coolant that  is recommended in

this Operation and Maintenance Manual,  “Fluid

Recommendations”. Failure to use the recommended

oil may result in engine damage.

Emergency Stopping

•  If freezing temperatures are  expected, check

the coolant for proper antifreeze protection. The

cooling system must be protected against freezing

to the lowest expected outside temperature. Add

the proper coolant/water mixture, if necessary.

NOTICE

Emergency shutoff controls are for EMERGENCY use

ONLY. DO  NOT  use emergency  shutoff devices  or

controls for normal stopping procedure.

•  Perform all required periodic maintenance on all

driven equipment. This maintenance is outlined in

the instructions from the OEM.

The OEM may have equipped the application with

an emergency stop button. For more  information

about the emergency stop button, refer to the OEM

information.

Ensure that any components for the external system

that support the engine operation are secured after

the engine is stopped.

Cold Weather Operation

Cold Weather Operation

Personal  injury  or property  damage  can  result

from alcohol or starting fluids.

i02581613

Cold Weather Operation

Alcohol or starting fluids are highly flammable and

toxic and if improperly stored could result in injury

or property damage.

Perkins Diesel Engines can operate effectively in

cold weather. During cold weather, the starting and

the operation of the diesel engine is dependent on

the following items:

Do not use aerosol types of starting aids such as

ether. Such use could  result in an explosion and

personal injury.

•  The type of fuel that is used

•  The viscosity of the engine oil

•  Optional Cold starting aid

•  Battery condition

Viscosity of the Engine Lubrication

Oil

Correct engine oil viscosity is essential. Oil viscosity

affects the amount  of torque that  is needed

to crank the  engine. Refer to Operation  and

Maintenance Manual, “Fluid Recommendations” for

the recommended viscosity of oil.

The operation and maintenance of  an engine in

freezing temperatures is complex . This is because

of the following conditions:

•  Weather conditions

•  Engine applications

Recommendations for the Coolant

Provide cooling system protection for  the lowest

expected outside temperature. Refer to this Operation

and Maintenance Manual, “Fluid Recommendations”

for the recommended coolant mixture.

Recommendations from your Perkins distributor are

based on past proven practices. The information that

is contained in this section provides guidelines for

cold weather operation.

In cold weather, check the  coolant often for the

correct glycol concentration in  order to ensure

adequate freeze protection.

Hints for Cold Weather Operation

•  If the engine will start, operate the engine until a

minimum operating temperature of 81 °C (177.8 °F)

is achieved. Achieving operating temperature will

help prevent the intake valves and exhaust valves

from sticking.

Engine Block Heaters

Engine block heaters  (if equipped) heat the

engine jacket water that surrounds the combustion

chambers. This provides the following functions:

•  The cooling system and the lubrication  system

for the engine do not lose heat immediately upon

shutdown. This means that an engine can be shut

down for a period of time and the engine can still

have the ability to start readily.

•  Startability is improved.

An electric block heater  can be activated once

the engine is stopped. An effective block heater is

typically a 1250/1500 W unit. Consult your Perkins

distributor for more information.

•  Install the correct specification of engine lubricant

before the beginning of cold weather.

•  Check all rubber parts (hoses, fan drive belts, etc)

weekly.

•  Check all electrical wiring and connections for any

fraying or damaged insulation.

•  Keep all batteries fully charged and warm.

•  Check the air cleaners and the air intake daily.

Fuel and the Effect from Cold

Weather

Note: Group 3 fuels reduce the life of the engine. The

use of Group 3 fuels is not covered by the Perkins

warranty.

Group 3 fuels include Low Temperature Fuels and

Aviation Kerosene Fuels.

Note: Only use grades of fuel that are recommended

by Perkins. Refer to this Operation and Maintenance

Manual, “Fluid Recommendations”.

Special fuels include Biofuel.

The cloud point is a temperature  that allows wax

crystals to form in the fuel. These crystals can cause

the fuel filters to plug.

The following fuels can be  used in this series of

engine.

•  Group 1

The pour point is the temperature when diesel fuel

will thicken. The diesel fuel becomes more resistant

to flow through fuel lines, fuel filters,and fuel pumps.

•  Group 2

•  Group 3

Be aware of  these facts when  diesel fuel is

purchased. Consider the average  ambient air

temperature for the engine’s application. Engines

that are fueled in one climate may not operate well if

the engines are moved to another climate. Problems

can result due to changes in temperature.

•  Special Fuels

Perkins prefer only Group 1 and Group 2 fuels for

use in this series of engines.

Group 1 fuels are the preferred Group of Fuels for

general use by Perkins. Group 1  fuels maximize

engine life and engine performance. Group 1 fuels

are usually less  available than Group 2 fuels.

Frequently, Group 1 fuels are not available in colder

climates during the winter.

Before troubleshooting for low power  or for poor

performance in the winter, check the fuel for waxing.

Low temperature fuels may be available for engine

operation at temperatures below 0 °C (32 °F). These

fuels limit the formation of  wax in the fuel at low

temperatures.

Note: Group 2 fuels must have a  maximum wear

scar of 650 micrometers (HFRR to ISO 12156-1).

For more information on cold weather operation, refer

to the Operation and Maintenance Manual, “Cold

Weather Operation and Fuel Related Components in

Cold Weather”.

Group 2 fuels are considered acceptable for issues

of warranty. This group of fuels may reduce the life

of the engine, the engine’s maximum power, and the

engine’s fuel efficiency.

When Group 2 diesel fuels are used the  following

components provide a means of minimizing problems

in cold weather:

•  Glow plugs (if equipped)

•  Engine coolant heaters, which may be an OEM

option

•  Fuel heaters, which may be an OEM option

•  Fuel line insulation, which may be an OEM option

There are three major differences between Group

1 fuels and Group 2 fuels. Group 1 fuels  have the

following different characteristics to Group 2 fuels.

•  A lower cloud point

•  A lower pour point

Fuel Related Components in

Cold Weather

Fuel Tanks

Condensation can form in partially filled fuel tanks.

Top off the fuel tanks after you operate the engine.

Fuel tanks should contain some provision for draining

water and sediment from the bottom of the  tanks.

Some fuel tanks use supply pipes that allow water

and sediment to settle below  the end of the fuel

supply pipe.

Some fuel tanks use  supply lines that take fuel

directly from the bottom of the tank. If the engine is

equipped with this system, regular maintenance of

the fuel system filter is important.

Drain the water and sediment from any fuel storage

tank at the following intervals: weekly, oil changes,

and refueling of the fuel tank. This will help prevent

water and/or sediment from being pumped from the

fuel storage tank and into the engine fuel tank.

Fuel Filters

A primary fuel filter is  installed between the fuel

tank and the engine fuel  inlet. After you change

the fuel filter, always prime the fuel system in order

to remove air bubbles from the fuel system. Refer

to the Operation and Maintenance Manual  in the

Maintenance Section for more information on priming

the fuel system.

The micron rating and the location of a primary fuel

filter is important in cold  weather operation. The

primary fuel filter and the fuel supply line are the most

common components that are affected by cold fuel.

Coolant Recommendations

Extended Life Coolant (ELC)

The following two coolants are used in Perkins diesel

engines:

Perkins provides Extended Life Coolant (ELC) for

use in the following applications:

Preferred  – Perkins Extended Life Coolant (ELC)

•  Heavy-duty spark ignited gas engines

•  Heavy-duty diesel engines

•  Automotive applications

Acceptable  – A commercial heavy-duty antifreeze

that meets “ASTM D4985” specifications

NOTICE

The anti-corrosion package for ELC is different from

the anti-corrosion package for other coolants. ELC

is an ethylene glycol base coolant. However, ELC

contains organic corrosion inhibitors and antifoam

agents with low amounts of  nitrite. Perkins ELC

has been formulated with the  correct amount of

these additives in order to provide superior corrosion

protection for all metals in engine cooling systems.

Do not use  a commercial coolant/antifreeze that  on-

ly meets the ASTM D3306 specification. This  type of

coolant/antifreeze is made for  light automotive appli-

cations.

Perkins recommends a 1:1 mixture of  water and

glycol. This mixture of water and glycol will provide

optimum heavy-duty performance as a antifreeze.

This ratio may be increased to 1:2 water to glycol if

extra freezing protection is required.

ELC is available in a 1:1 premixed  solution . The

Premixed ELC provides freeze protection to −36 °C

(−33 °F). The Premixed ELC is recommended for the

initial fill of the cooling system. The Premixed ELC is

also recommended for topping off the cooling system.

Note: A commercial heavy-duty  antifreeze that

meets “ASTM D4985” specifications MAY require a

treatment with an SCA at the initial fill. Read the label

or the instructions that are provided by the OEM of

the product.

ELC Concentrate is also available. ELC Concentrate

can be used to lower the freezing point  to −51 °C

(−60 °F) for arctic conditions.

In stationary engine applications and marine engine

applications that do not require anti-boil protection

or freeze protection, a mixture of  SCA and water

is acceptable. Perkins recommends a six percent

to eight percent concentration  of SCA in those

cooling systems. Distilled water or deionized water

is preferred. Water which has the  recommended

properties may be used.

Containers of several sizes are available. Consult

your Perkins dealer or your Perkins distributor for the

part numbers.

In order to maintain the correct balance  between

the antifreeze and the additives, you must maintain

the recommended concentration of Extended Life

Coolant (ELC). Lowering the proportion of antifreeze

lowers the proportion of additive. This will lower the

ability of the coolant to protect the system from pitting,

from cavitation, from erosion, and from deposits.

6.  Fill the cooling system with clean  water and

operate the engine until the engine is warmed to

49° to 66°C (120° to 150°F).

NOTICE

Do not use a conventional coolant to top-off a cooling

system that is filled with Extended Life Coolant (ELC).

NOTICE

Do not  use  standard supplemental  coolant additive

(SCA).

Incorrect or incomplete flushing of the cooling system

can result in damage to copper and other metal com-

ponents.

When using Perkins ELC, do not use standard SCA’s

or SCA filters.

To avoid damage to the cooling system, make sure to

completely flush the cooling system  with clear water.

Continue to flush the system until  all the signs of the

cleaning agent are gone.

ELC Cooling System Cleaning

Note: If the cooling system is already using  ELC,

cleaning agents are not  required to be used at

the specified coolant change  interval. Cleaning

agents are only required if the  system has been

contaminated by the addition of some other type of

coolant or by cooling system damage.

7.  Drain the cooling system into a suitable container

and flush the cooling system with clean water.

Note: The cooling system cleaner must be thoroughly

flushed from the cooling system. Cooling  system

cleaner that is left in the system will contaminate the

coolant. The cleaner may also corrode the cooling

system.

Clean water is the only cleaning agent that is required

when ELC is drained from the cooling system.

After the cooling system is drained  and after the

cooling system is refilled, operate the engine while

the cooling system filler cap is removed.  Operate

the engine until the coolant level reaches the normal

operating temperature and until the coolant  level

stabilizes. As needed, add the coolant  mixture in

order to fill the system to the specified level.

8.  Repeat Steps 6 and  7 until the system  is

completely clean.

9.  Fill the cooling system with the Perkins Premixed

ELC.

ELC Cooling System Contamination

Changing to Perkins ELC

NOTICE

Mixing ELC with other products reduces the effective-

ness of  the ELC and  shortens the  ELC service life.

Use only  Perkins Products  for premixed or  concen-

trate coolants.  Failure to follow  these recommenda-

tions can result  in shortened cooling system compo-

nent life.

To change from heavy-duty antifreeze to the Perkins

ELC, perform the following steps:

NOTICE

Care  must  be  taken  to  ensure  that  all  fluids  are

contained  during  performance of  inspection,  main-

tenance,  testing,  adjusting   and  the  repair  of   the

product. Be prepared to collect the  fluid with suitable

containers before  opening any  compartment or  dis-

assembling any component containing fluids.

ELC cooling systems can withstand contamination to

a maximum of ten percent of conventional heavy-duty

antifreeze or SCA. If the contamination exceeds ten

percent of the total system capacity, perform ONE of

the following procedures:

Dispose of all fluids according to local regulations and

mandates.

•  Drain the cooling system into a suitable container.

Dispose of the  coolant according to  local

regulations. Flush the system with clean water. Fill

the system with the Perkins ELC.

1.  Drain the coolant into a suitable container.

2.  Dispos, e of the coolant  according to local

regulations.

•  Drain a portion of the cooling system into a suitable

container according to local regulations. Then, fill

the cooling system with premixed ELC. This should

lower the contamination to less than 10 percent.

3.  Flush the system with clean water in  order to

remove any debris.

4.  Use Perkins cleaner to clean the system. Follow

the instruction on the label.

•  Maintain the system as a conventional Heavy-Duty

Coolant. Treat the system with an SCA. Change

the coolant at the interval that is recommended for

the conventional Heavy-Duty Coolant.

5.  Drain the cleaner into a suitable container. Flush

the cooling system with clean water.

Adding The SCA to  The Heavy-Duty

Coolant For Maintenance

Heavy-duty antifreeze of all types REQUIRE periodic

additions of an SCA.

Check the antifreeze  (glycol concentration) in

order to ensure adequate protection against boiling

or freezing. Perkins recommends  the use of a

refractometer for checking the glycol concentration.

Test the antifreeze periodically for the concentration

of SCA. For the  interval, refer to the Operation

and Maintenance Manual, “Maintenance Interval

Schedule” (Maintenance  Section). Test the

concentration of SCA.

Perkins engine cooling systems should be tested

at 500 hour  intervals for the concentration of

Supplemental Coolant Additive (SCA).

Additions of SCA are based on the  results of the

test. The size of the cooling system determines the

amount of SCA that is needed.

Additions of SCA are based on the results of the test.

An SCA that is liquid may be needed  at 500 hour

intervals.

Use the equation that is in Table 12 to determine the

amount of Perkins SCA that is required, if necessary:

(1)  This specification includes the requirements for Ultra Low Sulfur Diesel (ULSD). ULSD fuel will have ≤ 15 ppm (0.0015%) sulfur. Refer to

“ASTM D5453”, “ASTM D2622”, or “ISO 20846, ISO  20884” test methods. This specification includes the requirements for Low Sulfur

Diesel (LSD). LSD fuel will have ≤500 ppm (0.05%) sulfur. Refer to following:“ASTM 5453, ASTM D2622”,  “ISO 20846”, and “ISO 20884

test methods”.

(2)  A fuel with a higher cetane number is recommended in order to operate at a higher altitude or in cold weather.

(3)  “Via standards tables, the equivalent API gravity for the minimum density of 801  kg / m

3

(kilograms per cubic meter) is 45 and for  the

maximum density of 876 kg  / m  is 30”.

3

(4)  Regional regulations, national regulations or international regulations can require a fuel with a specific sulfur limit. Consult all applicable

regulations before selecting a fuel for a given engine application. Perkins fuel systems and engine components can operate on high sulfur

fuels. Fuel sulfur levels affect exhaust emissions.  High sulfur fuels also increase the potential for corrosion  of internal components.

Fuel sulfur levels above 0.5% may significantly  shorten the oil change interval. For additional information, refer to this manual, “Fluid

recommendations (General lubricant Information)”.

(5)  The values of the fuel viscosity are the values as the fuel is delivered to the  fuel injection pumps. Fuel should also meet the minimum

viscosity requirement and the fuel should meet the maximum viscosity  requirements at 40 °C (104 °F) of either the “ASTM D445” test

method or the “ISO 3104” test method. If a fuel  with a low viscosity is used, cooling of the fuel may be required to maintain  1.4 cSt or

greater viscosity at the fuel injection pump. Fuels  with a high viscosity might require fuel heaters in order to lower  the viscosity to 4.5

cSt at the fuel  injection pump.

(6)  Follow the test conditions and procedures for gasoline  (motor).

(7)  The lubricity of a fuel is a concern with low sulfur and ultra low  sulfur fuel. To determine the lubricity of the fuel, use the “ISO 12156-1

or ASTM D6079 High Frequency Reciprocating  Rig (HFRR)” test. If the lubricity of a fuel does not meet  the minimum requirements,

consult your fuel supplier. Do not treat the fuel without consulting the fuel  supplier. Some additives are not compatible. These additives

can cause problems in the  fuel system.

Fuel with a low cetane number can be the root cause

of problems during cold start.

NOTICE

Operating with fuels that do not meet the Perkins rec-

ommendations can cause the following effects: Start-

ing difficulty, poor combustion, deposits in the fuel in-

jectors, reduced  service life  of the  fuel system,  de-

posits in the  combustion chamber, and reduced ser-

vice life of the engine.

Viscosity

Viscosity is the  property of a liquid of  offering

resistance to shear or flow. Viscosity decreases with

increasing temperature. This decrease in viscosity

follows a logarithmic relationship for normal fossil

fuel. The common reference is to kinematic viscosity.

This is the quotient of the dynamic viscosity that is

divided by the density. The determination of kinematic

viscosity is normally by readings from gravity flow

viscometers at standard temperatures. Refer to “ISO

3104” for the test method.

Diesel Fuel Characteristics

Perkins Recommendation

Cetane Number

The viscosity of the fuel is significant because fuel

serves as a lubricant for the fuel system components.

Fuel must have sufficient viscosity in order to lubricate

the fuel system in both extremely cold temperatures

and extremely hot temperatures. If the  kinematic

viscosity of the fuel is lower than 1.4 cSt at the fuel

injection pump damage to the fuel injection pump

can occur. This damage can be excessive scuffing

and seizure. Low viscosity may lead to difficult hot

restarting, stalling and loss of performance.  High

viscosity may result in seizure of the pump.

Fuel that has a high cetane number will give a shorter

ignition delay. This will produce  a better ignition

quality. Cetane numbers are derived for fuels against

proportions of cetane and heptamethylnonane in the

standard CFR engine. Refer to “ISO 5165” for the

test method.

Cetane numbers in  excess of 45 are normally

expected from current diesel fuel. However, a cetane

number of 40 may be experienced in some territories.

The United States of America is one of the territories

that can have a low cetane value. A minimum cetane

value of 40 is  required during average starting

conditions. A higher cetane value may be required

for operations at high altitudes or in  cold weather

operations.

Perkins recommends kinematic viscosities of 1.4 and

4.5 mm2/sec that is delivered to the  fuel injection

pump.

Refill Capacities

Density

Lubricity

Density is the mass  of the fuel per unit volume

at a specific temperature. This  parameter has a

direct influence on engine performance and a direct

influence on emissions. This determines the heat

output from a given injected volume  of fuel. This

is generally quoted in the following kg/m at  15 °C

(59 °F).

This is the capability of the  fuel to prevent pump

wear. The fluid’s lubricity describes the ability of the

fluid to reduce the friction between surfaces that are

under load. This ability reduces the damage that is

caused by friction. Fuel injection systems rely on the

lubricating properties of the fuel. Until fuel sulfur limits

were mandated, the fuel’s lubricity was  generally

believed to be a function of fuel viscosity.

Perkins recommends a value of density of 841 kg/m

in order to obtain the correct power output. Lighter

fuels are acceptable but these fuels will not produce

the rated power.

The lubricity has particular significance to the current

low viscosity fuel, low sulfur fuel and low aromatic

fossil fuel. These fuels are made in order  to meet

stringent exhaust emissions. A  test method for

measuring the lubricity of  diesel fuels has been

developed and the test  is based on the HFRR

method that is operated at 60 °C (140 °F). Refer to

“ISO 12156 part 1 and CEC document F06-A-96” for

the test method.

Sulfur

The level of  sulfur is governed by  emissions

legislations. Regional regulation, national regulations

or international regulations can require a fuel with

a specific sulfur limit. The sulfur content of the fuel

and the fuel quality must comply with all existing local

regulations for emissions.

Lubricity wear scar diameter of 0.52 mm (0.0205 inch)

MUST NOT be exceeded. The fuel lubricity test must

be performed on a HFRR, operated at 60 °C (140 °F).

Refer to “ISO 12156-1 ”.

By using the test methods “ASTM D5453,  ASTM

D2622, or ISO 20846 ISO 20884”,  the content of

sulfur in low sulfur diesel (LSD) fuel must be below

500 PPM 0.05%. By using the test methods “ASTM

D5453, ASTM D2622, or ISO 20846 ISO 20884”, the

content of sulfur in ultra low sulfur (ULSD) fuel must

be below 15 PPM 0.0015%. The use of LSD fuel and

the use of ULSD fuel are acceptable provided that the

fuels meet the minimum requirements that are stated

in table 14. The lubricity  of these fuels must not

exceed wear scar diameter of 0.52 mm (0.0205 inch).

The fuel lubricity test must be performed on a HFRR,

operated at 60 °C (140 °F). Refer to “ISO 12156-1 ”.

Fuel additives can enhance the lubricity of  a fuel.

Contact your fuel supplier for those circumstances

when fuel additives are required. Your fuel supplier

can make recommendations for additives to  use

and for the proper  level of treatment. For more

information, refer to “Fuel Additive”.

Distillation

This is an indication  of the mixture of different

hydrocarbons in the fuel. A high ratio of light weight

hydrocarbons can affect the  characteristics of

combustion.

In some parts of the world and for some applications,

high sulfur fuels above 0.5% by  mass might only

be available. Fuel with  very high sulfur content

can cause engine wear. High sulfur fuel will  have

a negative impact on  emissions of particulates.

High sulfur fuel can be used provided that the local

emissions legislation will allow the use. High sulfur

fuel can be used in countries that do  not regulate

emissions.

Classification of the Fuels

Diesel engines have the ability to burn a wide variety

of fuels. These fuels are divided into  four general

groups: Ref to table 15

When only high sulfur  fuels are available, it will

be necessary that high alkaline  lubricating oil is

used in the engine or that the lubricating oil change

interval is reduced. Refer  to this Operation and

Maintenance Manual, “Fliud Recommendations

(Genernal Lubrication Information)” for information

on sulfur in fuel.

Methyl Ester (REM). This biodiesel is derived from

rapeseed oil. Soy Methyl Ester (SME) is the most

common biodiesel in the United States. This biodiesel

is derived from soybean oil. Soybean oil or rapeseed

oil are the primary  feedstocks. These fuels are

together known as Fatty Acid Methyl Esters (FAME).

This group of  fuel specifications is considered

acceptable, but only with an appropriate fuel additive,

but these fuels MAY reduce  the engine life and

Refill Capacities

Raw pressed vegetable oils are NOT acceptable for

use as a fuel in any concentration in compression

engines. Without esterification, these oils gel in the

crankcase and the fuel tank. These fuels may not be

compatible with many of the elastomers that are used

in engines that are manufactured today. In original

forms, these oils are not suitable for use  as a fuel

in compression engines. Alternate base stocks for

biodiesel may include animal tallow, waste cooking

oils, or a variety of other feedstocks. In order to use

any of the products that are  listed as fuel, the oil

must be esterified.

•  Biodiesel may pose low ambient  temperature

problems for both storage and operation. At low

ambient temperatures, fuel may need to be stored

in a heated building or a heated storage tank. The

fuel system may require heated fuel lines, filters,

and tanks. Filters may plug and fuel in the tank may

solidify at low ambient temperatures if precautions

are not taken. Consult your biodiesel supplier for

assistance in the blending and attainment of the

proper cloud point for the fuel.

•  Biodiesel has poor  oxidation stability, which

can result in long term problems in  the storage

of biodiesel. The poor  oxidation stability may

accelerate fuel oxidation  in the fuel system.

This is especially true in engines with electronic

fuel systems because these engines operate at

higher temperatures. Consult the fuel supplier for

oxidation stability additives.

Note: Engines that are manufactured by  Perkins

are certified by use of the prescribed Environmental

Protection Agency (EPA) and European Certification

fuels. Perkins does not certify engines on any other

fuel. The user of the engine has the responsibility

of using the correct fuel that  is recommended by

the manufacturer and allowed by the EPA and other

appropriate regulatory agencies.

•  Biodiesel is a fuel that can be made from a variety

of feedstock. The feedstock  that is used can

affect the performance of the product. Two of the

characteristics of the fuel that  are affected are

cold flow and oxidation stability. Contact your fuel

supplier for guidance.

Recommendation for the use of biodiesel

The neat biodiesel must conform to “EN14214” or

“ASTM D6751” regulations. A maximum  of 30%

mixture of biodiesel can be used in mineral diesel fuel.

The mineral diesel fuel must conform to “EN590”,

“ASTM D975” or “BS2869 Grade A2” regulations.

•  Biodiesel or biodiesel blends are not recommended

for engines that will operate occasionally.  This

is due to poor oxidation  stability. If the user is

prepared to accept some risk, then limit biodiesel

to a maximum of B5. Examples of applications that

should limit the use of biodiesel are the following:

Standby Generator sets and certain emergency

vehicles

Note: When biodiesel, or any blend of biodiesel is

used, the user has the responsibility for obtaining the

proper local exemptions, regional exemptions, and/or

national exemptions that are required for  the use

of biodiesel in any Perkins engine that is regulated

by emissions standards. Biodiesel that meets EN

14214 is acceptable. The biodiesel must be blended

with an acceptable  distillate diesel fuel at the

maximum stated percentages. However, the following

operational recommendations must be followed:

•  The oil change interval can be affected by the use

of biodiesel. Use Services Oil Analysis in  order

to monitor the condition of  the engine oil. Use

Services Oil Analysis also in order to determine the

oil change interval that is optimum.

•  Care must be taken in  order to remove water

from fuel tanks.  Water accelerates microbial

contamination and growth. When biodiesel  is

compared to distillate fuels, water is naturally more

likely to exist in the biodiesel.

•  Confirm that biodiesel is acceptable for use with

the manufacturer of the fuel filters.

•  In a comparison of distillate  fuels to biodiesel,

biodiesel provides less energy per gallon by 5% to

7%. Do NOT change the engine rating in order to

compensate for the power loss. This will help avoid

engine problems when the engine is converted

back to 100 percent distillate diesel fuel.

Fuel for Cold Weather Operation

The European standard “EN590” contains climate

dependant requirements and a range of options. The

options can be applied differently in each country.

There are 5 classes that are given to arctic climates

and severe winter climates. 0, 1, 2, 3, and 4.

•  The compatibility of the elastomers with biodiesel

is being monitored. The condition of  seals and

hoses should be monitored regularly.

Fuel that complies with “EN590 ” CLASS 4 can be

used at temperatures as low as −44 °C (−47.2 °F).

Refer to “EN590” for a  detailed discretion of the

physical properties of the fuel.

Perkins recognizes the fact  that additives may

be required in some special circumstances.  Fuel

additives need to be used  with caution. Contact

your fuel supplier for those  circumstances when

fuel additives are required. Your fuel supplier can

recommend the appropriate fuel additive and the

correct level of treatment.

The diesel fuel “ASTM D975 1-D” that is used in the

united states of america may be used in very cold

temperatures that are below −18 °C (−0.4 °F).

Note: For the best results, your fuel supplier should

treat the fuel when additives are required. The treated

fuel must meet the requirements that are stated in

table 14.

In extreme cold ambient conditions, you may also

use fuels that are listed in the table 16. These fuels

are intended to be used in temperatures that can be

Mixing alcohol or gasoline with diesel fuel can pro-

duce an explosive mixture in the engine crankcase

or the fuel tank.  Alcohol or gasoline must not be

used in order to dilute diesel fuel. Failure to follow

this instruction may result in death or personal in-

jury.

The “Engine  Manufacturers Association

Recommended Guideline on Diesel Engine Oil” is

recognized by Perkins. For detailed  information

about this guideline, see the latest edition of EMA

publication, “EMA DHD -1”.

There are many other diesel fuel specifications that

are published by governments and by technological

societies. Usually, those specifications do not review

all the requirements that are addressed in table 14.

To ensure optimum engine performance, a complete

fuel analysis should be  obtained before engine

operation. The fuel analysis should include all of the

properties that are stated in the table 14.

API Oils

The Engine Oil Licensing and Certification System by

the American Petroleum Institute (API) is recognized

by Perkins. For detailed  information about this

system, see the latest edition of the “API publication

No. 1509”. Engine oils that bear the API symbol are

authorized by API.

Fuel Additive

Supplemental diesel fuel additives are not generally

recommended. This is due to potential damage to

the fuel system or the  engine. Your fuel supplier

or the fuel manufacturer will add  the appropriate

supplemental diesel fuel additives.

EMA DHD-1  – The  Engine Manufacturers

Association (EMA) has  developed lubricant

recommendations as an alternative to the  API oil

classification system. DHD-1 is a Recommended

Guideline that defines a level of oil performance for

these types of diesel engines: high speed, four stroke

cycle, heavy-duty, and light duty. DHD-1 oils may

be used in Perkins engines when the following oils

are recommended: API CH-4, API CG-4, and API

CF-4. DHD-1 oils are intended to provide superior

performance in comparison to API CG-4 and  API

CF-4.

g00546535

Illustration 18

Typical API symbol

DHD-1 oils will meet the needs of high performance

Perkins diesel engines that are operating in many

applications. The tests and the test limits  that are

used to define DHD-1 are similar  to the new API

CH-4 classification. Therefore, these oils will also

meet the requirements for diesel engines that require

low emissions. DHD-1 oils are designed to control the

harmful effects of soot with improved wear resistance

and improved resistance to plugging of the oil filter.

These oils will also provide superior control of piston

deposit for engines with either two-piece steel pistons

or aluminum pistons.

Diesel engine oils CC,  CD, CD-2, and CE have

not been API authorized  classifications since 1

January 1996. Table 17 summarizes the status of

the classifications.

All DHD-1 oils must complete a  full test program

with the base stock and with the viscosity grade of

the finished commercial oil. The use of “API  Base

Oil Interchange Guidelines” are not appropriate for

DHD-1 oils. This feature reduces the  variation in

performance that can occur when base stocks are

changed in commercial oil formulations.

(1)  The oil CD-2 is for a two-cycle diesel engine. Perkins does not

sell engines that utilize CD-2 oil.

Terminology

Certain abbreviations follow the nomenclature of

“SAE J754”. Some classifications follow “SAE J183”

abbreviations, and some classifications follow the

“EMA Recommended Guideline on Diesel Engine

Oil”. In addition to Perkins definitions, there are other

definitions that will be of assistance in  purchasing

lubricants. Recommended oil viscosities can be found

in this publication, “Fluid Recommendations/Engine

Oil” topic (Maintenance Section).

DHD-1 oils are recommended for use in extended oil

change interval programs that optimize the life of the

oil. These oil change interval programs are based

on oil analysis. DHD-1 oils are recommended  for

conditions that demand a premium oil. Your Perkins

dealer or your Perkins distributor has the  specific

guidelines for optimizing oil change intervals.

API CH-4 – API CH-4 oils were developed in order to

meet the requirements of the new high performance

diesel engines. Also,  the oil was designed to

meet the requirements of the low emissions diesel

engines. API CH-4 oils are also acceptable for use

in older diesel engines and in diesel  engines that

use high sulfur diesel fuel. API CH-4  oils may be

used in Perkins engines that use API CG-4 and API

CF-4 oils. API CH-4 oils will generally exceed the

performance of API CG-4 oils in the following criteria:

deposits on pistons, control of oil consumption, wear

of piston rings, valve train wear, viscosity control,

and corrosion.

Engine Oil

Commercial Oils

The performance of commercial  diesel engine

oils is based  on American Petroleum Institute

(API) classifications. These API classifications are

developed in order to provide commercial lubricants

for a broad range of diesel engines that operate at

various conditions.

Only use commercial oils that meet the  following

classifications:

•  API CH-4 CI-4

Maintenance Section

Refill Capacities

Three new engine tests were developed for the API

CH-4 oil. The first test specifically evaluates deposits

on pistons for engines with the two-piece steel piston.

This test (piston deposit) also measures the control

of oil consumption. A  second test is conducted

with moderate oil soot. The second test measures

the following criteria: wear of piston rings, wear of

cylinder liners, and resistance to corrosion. A third

new test measures the following characteristics with

high levels of soot in the oil: wear of the valve train,

resistance of the oil in  plugging the oil filter, and

control of sludge.

In addition to the new  tests, API CH-4 oils have

tougher limits for viscosity control in applications that

generate high soot. The oils  also have improved

oxidation resistance. API CH-4 oils must pass an

additional test (piston deposit) for engines that use

aluminum pistons (single piece). Oil performance is

also established for engines that operate in areas

with high sulfur diesel fuel.

All of these improvements  allow the API CH-4

oil to achieve optimum oil  change intervals. API

for conditions that demand  a premium oil. Your

Perkins dealer or your Perkins distributor has specific

guidelines for optimizing oil change intervals.

•

•

Choose an oil with the highest TBN that meets one

of these classifications: EMA DHD-1 and API CH-4.

Reduce the oil change  interval. Base the oil

change interval on the oil analysis. Ensure that the

oil analysis includes the condition of the oil and a

wear metal analysis.

Some commercial  oils that meet  the API

classifications may require reduced  oil change

intervals. To determine the oil change interval, closely

monitor the condition of the oil and perform a wear

metal analysis.

Excessive piston deposits can be produced by an oil

with a high TBN. These deposits can lead to a loss

of control of the oil consumption and to the polishing

of the cylinder bore.

NOTICE

Failure to follow these oil recommendations can cause

shortened engine service  life due to deposits  and/or

excessive wear.

NOTICE

Operating Direct Injection (DI) diesel engines with fuel

sulphur levels over 0.5 percent will require shortened

oil change intervals in order to help maintain adequate

wear protection.

Re-refined Base Stock Oils

Re-refined base stock  oils are accept, able for

use in Perkins  engines if these oils  meet the

performance requirements that are specified  by

Perkins. Re-refined base stock oils  can be used

exclusively in finished oil or in a combination  with

new base stock oils. The US military specifications

and the specifications of other  heavy equipment

manufacturers also allow the use of re-refined base

stock oils that meet the same criteria.

Refer to Table 19 (maximum temperature) in order

to select the oil viscosity for engine operation at the

highest ambient temperature that is anticipated.

Generally, use the highest  oil viscosity that is

available to meet the requirement for the temperature

at start-up.

Table 19

The process that is used to make re-refined  base

stock oil should adequately remove all wear metals

that are in the used  oil and all the additives that

are in the used  oil. The process that is used to

make re-refined base stock oil generally involves the

process of vacuum distillation and hydrotreating the

used oil. Filtering is adequate for the production of

high quality, re-refined base stock oil.

Lubricants for Cold Weather

When an engine is started and an engine is operated

in ambient temperatures below −20 °C (−4 °F), use

multigrade oils that are capable  of flowing in low

temperatures.

These oils have lubricant viscosity grades of SAE

0W or SAE 5W.

Synthetic Base Stock Oils

When an engine is started and operated in ambient

temperatures below −30 °C (−22 °F), use a synthetic

base stock multigrade oil with an 0W viscosity grade

or with a 5W viscosity grade. Use an oil with a pour

point that is lower than −50 °C (−58 °F).

Synthetic base oils  are acceptable for use in

these engines if these oils meet the  performance

requirements that are specified for the engine.

Synthetic base oils generally perform better  than

conventional oils in the following two areas:

The number of acceptable lubricants is  limited in

cold weather conditions. Perkins recommends the

following lubricants for use in cold weather conditions:

•  Synthetic base oils have improved  flow at low

temperatures especially in arctic conditions.

First Choice  – Use oil  with an EMA DHD-1

Recommended Guideline. Use a CH-4 oil that has

an API license. The oil should be either SAE 0W20,

SAE 0W30, SAE 0W40, SAE 5W30, or SAE 5W40

lubricant viscosity grade.

•  Synthetic base oils have  improved oxidation

stability especially at high operating temperatures.

Some synthetic base  oils have performance

characteristics that enhance the service life of the

oil. Perkins does not  recommend the automatic

extending of the oil change intervals for any type of

oil.

Second Choice  – Use an oil that  has a CH-4

additive package. Although the oil  has not been

tested for the requirements of the API license, the oil

must be either SAE 0W20, SAE 0W30, SAE 0W40,

SAE 5W30, or SAE 5W40.

Shortened engine  service life  could result if  second

choice oils are used.

Aftermarket Oil Additives

•  Tests are  conducted in order  to detect

contamination of the oil by water, glycol or fuel.

Perkins does not recommend the use of aftermarket

additives in oil. It is not necessary to use aftermarket

additives in order to achieve the engine’s maximum

service life or rated performance. Fully formulated,

finished oils consist of base oils and of commercial

additive packages. These additive packages are

blended into the base oils at precise percentages in

order to help provide finished oils with performance

characteristics that meet industry standards.

•  The Oil Condition Analysis determines the loss of

the oil’s lubricating properties. An infrared analysis

is used to compare the properties of new oil to the

properties of the used oil sample. This analysis

allows technicians to determine the amount  of

deterioration of the oil during use. This analysis

also allows technicians to verify the performance

of the oil according to the specification during the

entire oil change interval.

There are no industry standard tests that evaluate

the performance or the compatibility of aftermarket

additives in finished oil. Aftermarket additives may

not be compatible with the  finished oil’s additive

package, which could lower the performance of the

finished oil. The aftermarket additive could  fail to

mix with the finished oil. This could produce sludge

in the crankcase. Perkins discourages the  use of

aftermarket additives in finished oils.

To achieve the best performance  from a Perkins

engine, conform to the following guidelines:

•  Select the correct oil, or a commercial oil that meets

the “EMA Recommended Guideline on  Diesel

Engine Oil” or the recommended API classification.

•  See the appropriate “Lubricant Viscosities” table in

order to find the correct oil viscosity grade for your

engine.

•  At the specified interval, service the engine. Use

new oil and install a new oil filter.

•  Perform maintenance at the  intervals that are

specified in the  Operation and Maintenance

Manual, “Maintenance Interval Schedule”.

Oil analysis

Some engines may be equipped with an oil sampling

valve. If oil analysis is required the oil sampling valve

is used to obtain samples of the engine oil. The oil

analysis will complement the preventive maintenance

program.

The oil analysis is a diagnostic tool that is used to

determine oil performance and component wear

rates. Contamination can be identified and measured

through the use of the oil analysis. The oil analysis

includes the following tests:

•  The Wear Rate Analysis monitors the wear of the

engine’s metals. The amount of wear metal and

type of wear metal that is in the oil is analyzed. The

increase in the rate of engine wear metal  in the

oil is as important as the quantity of engine wear

metal in the oil.

Perkins recommends a scheduled inspection  of

the alternator. Inspect  the alternator for loose

connections and correct battery charging. Check the

ammeter (if equipped) during engine operation in

order to ensure correct battery performance and/or

correct performance of the electrical system. Make

repairs, as required.

Note: Adjust the frequency of cleaning according to

the effects of the operating environment.

Inspect the cooling air side of the aftercooler for these

items: damaged fins, corrosion, dirt, grease, insects,

leaves, oil, and other debris. Clean the cooling air

side of the aftercooler, if necessary.

Check the alternator and the  battery charger for

correct operation. If the  batteries are correctly

charged, the ammeter reading should be very near

zero. All batteries should  be kept charged. The

batteries should be kept warm because temperature

affects the cranking power. If the battery is too cold,

the battery will not  crank the engine. When the

engine is not run for long periods of  time or if the

engine is run for short periods, the batteries may not

fully charge. A battery with a low charge will freeze

more easily than a battery with a full charge.

For air-to-air aftercoolers, use the same methods that

are used for cleaning the outside of radiators.

Personal injury can result from air pressure.

Personal injury can result without following prop-

er procedure. When using pressure air, wear a pro-

tective face shield and protective clothing.

Maximum air pressure at the nozzle must be less

than 205 kPa (30 psi) for cleaning purposes.

Battery - Replace

Pressurized air is the preferred method for removing

loose debris. Hold the nozzle approximately 6 mm

(0.25 inch) away from the fins. Slowly move the air

nozzle in a direction that is parallel with the tubes.

This will remove debris that is between the tubes.

Batteries give  off combustible  gases  which can

explode. A spark can cause the combustible gas-

es to ignite. This can result in severe personal in-

jury or death.

Pressurized water may also be used for cleaning.

The maximum water pressure for cleaning purposes

must be less than 275 kPa (40 psi). Use pressurized

water in order to soften mud.

Ensure proper ventilation for batteries that are  in

an enclosure. Follow the proper procedures in or-

der to help  prevent electrical arcs  and/or sparks

near batteries. Do  not smoke when  batteries are

serviced.

Use a degreaser and steam for removal of oil and

grease. Wash the core with detergent and hot water.

Thoroughly rinse the core with clean water.

After cleaning, start the engine. Run the engine for

two minutes. This will help in the removal of debris

and drying of the core.  Stop the engine. Inspect

the core for cleanliness.  Repeat the cleaning, if

necessary.

The battery cables or the batteries  should not be

removed with the battery cover in place. The bat-

tery cover should be  removed before any servic-

ing is attempted.

Inspect the fins for damage. Bent fins may be opened

with a “comb”.

Removing the battery cables or the batteries with

the cover in place may cause a battery explosion

resulting in personal injury.

Inspect these items for  good condition: welds,

Belts - Inspect/Adjust/Replace

Inspection

Inspect the alternator belt and the fan drive belts for

wear and for cracking. Replace the belts if the belts

are not in good condition.

Check the belt tension according to the information

in Systems Operation, Testing and Adjusting, “Belt

Tension Chart”.

Slippage of loose belts can reduce  the efficiency

of the driven components. Vibration of loose belts

can cause unnecessary wear  on the following

components:

•  Belts

•  Pulleys

•  Bearings

If the belts are too tight, unnecessary stress is placed

on the components. This reduces the service life of

the components.

Replacement

g01391209

Illustration 20

For applications that require multiple  drive belts,

replace the drive belts in matched sets. Replacing

one drive belt of a matched set will cause the new

drive belt to carry more load because the older drive

belts are stretched. The additional load on the new

drive belt could cause the new drive belt to fail.

1.  Remove the belt guard.

2.  Loosen alternator pivot bolt (2) .

3.  Loosen the setscrew for the adjustment link (1).

4.  Move the assembly in  order to increase or

decrease the belt tension.  Refer to Systems

Operation, Testing and Adjusting, “Belt Tension

Chart”.

5.  Tighten the setscrew for the adjustment link (1)

securely. Tighten alternator pivot bolt (2) securely.

6.  Reinstall the belt guard.

If new alternator belts are installed,  check the

tension of the alternator  belt again after 10

minutes of engine operation at the rated rpm.

7.  Remove the belt guard and check the belt tension.

When the correct belt tension is obtained, fit the

belt guard.

Cooling System  Water

Temperature Regulator  -

Replace

Replace the water temperature regulator  before

the water temperature regulator  fails. This is a

recommended preventive maintenance practice.

Replacing the water temperature regulator reduces

the chances for unscheduled downtime.

A water temperature  regulator that fails in  a

partially opened position can cause overheating or

overcooling of the engine.

g00285520

Illustration 23

Cooling system filler cap

A water temperature regulator that fails in the closed

position can cause excessive overheating. Excessive

overheating could result in cracking of the cylinder

head or piston seizure problems.

Pressurized System: Hot coolant  can cause seri-

ous burns. To open the cooling system filler  cap,

stop the engine and wait until the cooling system

components are cool. Loosen the cooling system

pressure cap slowly  in order to  relieve the pres-

sure.

A water temperature regulator that fails in the open

position will cause the engine operating temperature

to be too low during  partial load operation. Low

engine operating temperatures during partial loads

could cause an excessive carbon buildup inside the

cylinders. This excessive carbon buildup could result

in an accelerated wear of the piston rings and wear

of the cylinder liner.

1.  Remove the cooling system filler cap slowly in

order to relieve pressure.

2.  Maintain the coolant level within 13 mm (0.5 inch)

of the bottom of the filler  pipe. If the engine is

equipped with a sight glass, maintain the coolant

level to the proper level in the sight glass.

Refer to Disassembly  and Assembly, “Water

Temperature Regulator Housing -  Remove and

Install” for the replacement procedure of the water

temperature regulator, or consult  your Perkins

distributor.

Note: If only the water temperature regulators are

replaced, drain the coolant from the cooling system to

a level that is below the water temperature regulator

housing.

i02151646

Crankshaft Vibration Damper

- Inspect

Driven Equipment - Check

Refer to the OEM specifications for more information

on the following maintenance recommendations for

the driven equipment:

Damage to the crankshaft vibration damper or failure

of the crankshaft vibration damper can  increase

torsional vibrations. This can result in damage  to

the crankshaft and to other engine components. A

damper that is damaged can cause excessive gear

train noise at variable points in the speed range.

•  Inspection

•  Adjustment

•  Lubrication

The damper is mounted to the crankshaft which is

located behind the belt guard on  the front of the

engine.

•  Other maintenance recommendations

Perform any maintenance for the driven equipment

which is recommended by the OEM.

Visconic Damper

The visconic damper has a weight that is  located

inside a fluid filled case. The weight moves in  the

case in order to limit torsional vibration.

i02784833

Electronic Unit  Injector -

Inspect/Adjust

Inspect the damper for evidence  of fluid leaks. If

a fluid leak is found,  determine the type of fluid.

The fluid in the damper is silicone. Silicone has the

following characteristics: transparent, viscous, and

smooth.

If the fluid leak is oil, inspect the crankshaft seals for

leaks. If a leak is observed, replace the crankshaft

seals.

Be sure  the engine  cannot be started  while this

maintenance is being performed. To prevent pos-

sible injury, do not use the  starting motor to turn

the flywheel.

Inspect the damper and repair or replace the damper

for any of the following reasons:

Hot engine  components can cause  burns. Allow

additional time for the engine to cool before mea-

suring/adjusting the unit injectors.

•  The damper is dented, cracked, or leaking.

•  The paint on the damper is discolored from heat.

The electronic unit injectors use high voltage. Dis-

connect the unit injector enable circuit connector

in order to  prevent personal injury. Do  not come

in contact with the injector terminals while the en-

gine is running.

•  The engine has had a failure because of a broken

crankshaft.

•  Analysis of the oil has revealed that the front main

bearing is badly worn.

•  There is a large amount of gear train wear that is

not caused by a lack of oil.

The operation of Perkins engines  with improper

adjustments of the electronic unit injector can reduce

engine efficiency. This reduced efficiency could result

in excessive fuel usage and/or shortened engine

component life.

•  The temperature of the damper fluid is too high.

Refer to the Service Manual or consult your Perkins

distributor for information about damper replacement.

Only qualified service personnel should  perform

this maintenance. Refer to  the following topics

for your engine for the  correct procedure: Refer

to the Systems Operation, Testing and Adjusting,

“Electronic Unit Injector - Test” for the test procedure,

and Systems Operation, Testing and  Adjusting,

“Electronic Unit Injector - Adjust”  for the correct

procedure for adjusting the injectors.
