3. Calculation of total end play
Select a suitable bearing race from the table below so that clearance C will be within 0.25 to 0.55 mm (0.0098 to 0.0217 in).
C = (L + G) − L
|
C |
Clearance between concave section of high clutch and end of clutch drum support |
|
L |
Length from case mating surface to the concave portion of the high clutch |
|
G |
Gasket thickness [0.28 mm (0.0110 in)] |
|
L |
Height from the oil pump housing mating surface to the upper surface of the oil pump cover with the thrust needle bearing. |

4. After completing the end play adjustment, insert the bearing race into the high clutch race. Apply vaseline, and install the thrust needle bearing to the oil pump cover.
5. After correctly installing the new 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 case.
6. Install both parts with dowel pins aligned. Make sure there is no clearance at the mating surface.
