Front Crankshaft Seal: Testing and Inspection
CLEANING
Clean cover and housing gasket mating surfaces. Use a suitable scraper and be careful not to damage the gear housing surface, since it is aluminum.
Remove any old sealer from the oil seal bore. Thoroughly clean the front seal area of the crankshaft. The seal lip and the sealing surface on the
crankshaft must be free from all oil residue to prevent seal leaks.
INSPECTION
Inspect the gear housing and cover for cracks and replace if necessary. Carefully straighten any bends or imperfections in the gear cover with a
ball-peen hammer on a flat surface. Inspect the crankshaft front journal for any grooves or nicks that would affect the integrity of the new seal.
