Illustration 70
Typical example
1. Before installation of the crankshaft front seal
and the wear sleeve, inspect the crankshaft for
scratches. Also, inspect the crankshaft for any
distortion on the surface that may lead to an out of
round condition. Use a polishing cloth in order to
remove any imperfections on the crankshaft.
1. Use a 4 mm (0.158 inch) drill in order to make
three or more holes in wear sleeve (2).
2. Use Tooling (A) to remove the wear sleeve.
3. Use a 4 mm (0.158 inch) drill in order to make

8. Use Tooling (D) to move camshaft (8) toward the
front of the engine. Reposition Tooling (D), as
required.
Note: Avoid lifting the camshaft with Tooling (D). The
camshaft should rest on Tooling (A). Lifting of the
camshaft can cause misalignment as the camshaft
is removed, resulting in damage to the camshaft
bearings.

rod and the connecting rod cap, if necessary.
Note: Mark the components of each piston and
connecting rod assembly. The components must be
reinstalled in the original location. Do not interchange
components.
Note: Do not stamp the connecting rod assembly.
Stamping or punching the connecting rod assembly
could cause the connecting rod to fracture.
