Calculation of total end play.
Select suitable bearing race from among those listed in this table so that clearance C is in the 0.25 to 0.55 mm (0.0098 to 0.0217 in) range. See Fig 5

C = (L + G) - l

After completing end play adjustment, insert the bearing race in the recess of the high clutch. Attach the thrust needle bearing to the oil pump cover with vaseline.
After correctly installing the gasket to the case mating surface, carefully install the oil pump housing assembly. Be careful to avoid hitting the drive pinion against the inside of the case.
CAUTION:
- Be careful not to damage the seal ring.
- Be sure to use a new gasket.
Install both parts with dowel pins aligned. Make sure no clearance exists at the mating surface.
NOTE: Any clearance suggests a damaged seal ring.
