Crankshaft: Service and Repair
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.
Inspect the rod and main journals for deep scores, signs of overheating and other abnormal marks.
