prevent leaks. The crankshaft and seal surface
must be completely dry when the seal is installed.
1. Clean cover and housing gasket mating surfaces.
Use a suitable scraper and be careful not to dam-
age the gear housing surface. Remove any old
sealer from the oil seal bore. Thoroughly clean the
front seal area of the crankshaft. Do not sand this
surface. The seal lip and the sealing surface on the
crankshaft must be free from all oil residue to pre-
vent seal leaks.
2. 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.

holes and remove the rear seal with a slide ham-
mer (4).
INSTALLATION
CAUTION: The seal lip and the sealing surface on the crankshaft must be freefrom all oil residue to prevent
seal leaks. The crankshaft and seal surfaces must be completely dry when the seal is installed. Use a soap
and water solution on outside diameter of seal to ease assembly.
1. Clean the crankshaft journal with a suitable solvent and dry with a cleanshop towel or compressed air. Wipe the
inside bore of the crankshaft seal retainer with a clean shop towel.
2. Inspect the crankshaft journal forgouges, nicks, or other imperfections. If the seal groove in the crankshaft is
excessively deep, install the new seal 1/8” deeper into the retainer bore,or obtain a crankshaft wear sleeve that
is available in the aftermarket.
