Notes:
For emissions approved engines. If a new fuel injection pump is fitted, shims of the same thickness as the
originals and a pump with the same part number must be fitted.
For emissions approved engines. If the fuel injection pump is put back, it is essential that the fuel
adjustment screw is not altered from the original setting. The maximum No Load Speed should be checked
after assembly.

To vent the 100 series fuel system
1 Identify the location of fuel lift pump (A3).
2 Locate the vent screw on top of the fuel filter (A2) and loosen off.
3 Operate the hand primer on lift pump until air free fuel flows. Tighten the vent screw.
4 Identify the vent screw on the fuel injection pump (A4) and loosen off. Operate the hand primer until air free
fuel flows. Tighten the vent screw.
5 Identify the fuel pipes from fuel injection pump to the atomiser (A1) and loosen them all off at the atomiser
end. Operate the starter motor until fuel flows from the injector pipes. Tighten all pipe connections.
The engine is now ready to start.
Caution: When the starter motor is operated, do not exceed continuous rotation for more than 15 second
periods. Wait for 30 seconds between periods of turning if fuel does not flow on initial rotation.

Description
Part number
Silicone RTV sealing and jointing compound
1861108
Notes:
On assembly apply Powerpart silicone RTV sealing and jointing compound to the cylinder block of 102-05,
103-07 and 103-10 engines.
A small amount of leakage of coolant across the surface of the face seal in the coolant pump is normal. Its
purpose is to provide lubrication for the seal. There is a hole in the coolant pump body to allow coolant to
drain. Small amounts of coolant might be seen intermittently from the drain hole during the engine operation
cycle.
Signs of a coolant through the drain hole are not an indication that the pump is faulty. Coolant stains or
intermittent drops of coolant from the hole, indicate normal operation of the pump.

Alternator Testing
Operation 14-3
To avoid the return of parts that are not faulty, follow this procedure for all suspected failures. This will isolate
the problem between either the alternator or the main electrical system.
Check that all connections to the alternator are secure and free from contamination. If the alternator is earthed
using the engine block check that there is a good connection between the alternator, the earth connection and
the engine block. If the alternator mounting bracket is of the black painted type, the bracket should be removed
from the engine block and the paint removed from the mounting surfaces between the alternator, the mounting
bracket and the engine block.
If the machine tachometer is not operating, check the security of the ‘W’ terminal (A3, B3).
If the alternator is excessively contaminated by dust or dirt, use an airline and compressed air applied to the
vent holes on the alternator.
If the ignition warning lamp is illuminated, check the phase wiring (A4, B1).
Check the alternator charging voltage with a volt meter between the alternator +Ve (A1, B2) and the alternator
earth terminal (A2) when the engine is operating at idle, with the minimal electrical load. The voltage should
be between 13.6 and 14.7 volts, if it is outside this range then the alternator is faulty.

Starter Motor Testing
Operation 14-5
Before removing a suspect faulty starter motor, check the security of all of the electrical connections on the
starter motor.
To test the starter motor use:
12 volt fully charged battery (A5).
Two heavy duty cables with suitable clips.
One small lead with an in-line switch capacity of 5 amperes minimum. The switch (A1) should be of the
push to make type.
Secure the starter motor in a vice.
Connect the leads as shown in the diagram (A2, A3, A4), there should be no operation of the starter motor. If
there is any smoke, buzzing or sparking from the starter motor, it is faulty.
Operate the switch and the solenoid should operate, moving the pinion forward to engage the starter. The
starter motor pinion will then rotate. Releasing the switch will allow the pinion to retract and stop rotating.
If there is any abnormal noise, such as knocking, electrical buzzing, smoke, the starter does not operate, or
the pinion does not move forward or backward, or the pinion does not rotate, the starter motor is faulty.
If the starter motor operates correctly then the machine electrical system is faulty.
A1 - Lead with push button switch.
A2 - Lucar connector for ignition switch.
A3 - Starter earth connection 8.0 - 8.5 Nm
A4 - Solenoid connection 5.6 - 6.2 Nm.
A5 - 12 volt battery.
Note: The starter motor earth (A3) should be connected directly to B- or via another earth. This should not be
used as the main engine earth.

Note: Alternator charge lamp rating: 12V - 2.2W at 850 rev/min.
When the engine is at rest the alternator charge lamp is illuminated via the battery and it extinguishes when
the alternator operates.
The use of a lower wattage bulb than the above will increase the speed at which self excitation occurs upon
initial run up, e.g. a charge lamp with a lower wattage bulb will have a rating of 12V - 1.2W at 1300 rev/min.
