F: ADJUSTMENT
1) Remove the liquid gasket completely.
2) Install the oil pump housing assembly to torque

ening four bolts evenly.
NOTE:
Use an old gasket or an aluminum washer so as not
to damage the mating surface of housing.

5) Apply red lead evenly to the surfaces of three or
four teeth on hypoid driven gear. Rotate the drive
pinion in the forward and reverse directions for sev-
eral times. Remove the oil pump housing, and
check the tooth contact pattern.
If the tooth contact is improper, readjust the back-
lash or shim thickness.

Correct tooth contact
Checking item: Tooth contact pattern is slightly
shifted toward to toe side under no-load
rotation. [When loaded, contact pattern moves
toward heel.]
