4) After completing the total end play adjustment,
insert the bearing race in recess of the high clutch.
Install the thrust needle bearing to oil pump cover
using vaseline.
5) After correctly install the new gasket to the case
mating surface, carefully install the oil pump hous-
ing assembly. Be careful to avoid hitting the drive
pinion against the inside of case.
6) Install both parts with dowel pins aligned. Make
sure no clearance at mating surface.
