Crankshaft - Cleaning and Inspection
Cleaning the Crankshaft
Clean the crankshaft oil drillings with a nylon brush.
Rinse in clean solvent and dry with compressed air.
Inspecting the Crankshaft
inspect the front and rear seal contact areas of the crankshaft
for scratches or grooving.
The service seal kit will position the seal slightly deeper into the
seal bore so it will contact the crankshaft at a different location.
If this has already been done and the crankshaft has two worn
areas, install a wear sleeve to provide a new contact surface for
the seal.
