Inspect for Reuse (001-025-007)
Inspect the seal contact area of the crankshaft for a wear
groove. If the seal has worn a groove deep enough to be
felt with a sharp object or fingernail, it will be necessary to
install a wear sleeve to prevent an oil leak.
The oil seal used with the wear sleeve has a larger inside
diameter than the standard seal. The two seals are not
interchangeable. Refer to the appropriate B Series parts
catalog for the correct part number.
