REPAIR
a.
Use solvent to clean the front gear housing. Inspect the gear cover seal bore for grooves and burrs.
Remove all burrs which would damage the oil seal outside diameter and cause leakage.
b.
Inspect the crankshaft oil seal wear surface for nicks, scratches, and sharp edges. Remove them by
using 240 grit emery cloth dipped in clean lubricating oil. Use crocus cloth for a finalpolishing.
c.
If the previous seal was operated with a wear sleeve, the sleeve must be removed and discarded. Oil
seals are sized to operate directly on the shaft surface without a wear sleeve.
NOTE
Repair sleeves are available for crankshaft oil seal surfaces that are badly
grooved or mutilated, where a renewed surface is desirable for the seal lip to
seat.
