CRANKSHAFT SHAFT SEAL:
The shaft seal is located at the flywheel end of the
crankshaft. If significant oil leakage develops, it should be replaced. The procedure for replacing the
seal is given here.
REMOVAL
a.
Remove flywheel and bushing by removing the three cap screws that secure the flywheel
and hub to the crankshaft. Use these screws in the hub tapped holes to jack the flywheel
from the bushing.
b.
If possible, remove the seal with crankshaft intact. If this is not successful, the entire unit
must be disassembled and the crankshaft removed prior to seal removal.
c.
Inspect the crankshaft surface where the oil seal makes contact. Remove any burrs or
scratches that might inhibit a tight seal. Be careful to avoid getting any foreign material
on the exposed bearing.
REASSEMBLY
a.
Reassemble in the reverse order, using a new oil seal.
b.
Be sure that the flywheel and drive sheave are lined up. This can be accomplished by
laying a straight edge across the sheave faces.

b.

the guide piston.
c.
Reinstall in reverse order. Install with mark “F” or "M" (on lower flange of cylinder)
towards flywheel. Use new gaskets if necessary.
