(8) Apply red lead evenly to the surfaces of three or
four teeth of the crown gear. Rotate the drive pinion in
the forward and reverse directions several times. Then
remove the oil pump housing, and check the tooth con-
tact pattern.
If tooth contact is improper, readjust the backlash or
shim thickness.
Checking item Contact pattern Corrective action
Tooth contact
Tooth contact pattern is slightly shifted
toward to under no-load rotation.
[When loaded, contact pattern moves
toward heel.]

24) Install the oil pump housing assembly.
(1) After completing end play adjustment, insert the
bearing race in the recess of the high clutch. Attach the
thrust washer and thrust needle bearing to the oil pump
cover with vaseline.
(2) After correctly installing the gasket to the case mat-
ing 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.

(3) Install both parts with dowel pins aligned. Make
sure no clearance exists at the mating surface.
NOTE:
Any clearance suggests a damaged seal ring.

2) Selection of oil pump components (rotor, vanes, control
piston and cam ring)
(1) Using a micrometer, measure the height of the
rotor, vanes, control piston and cam ring in at least four
positions. (Measure the height at one place for each of
the nine vanes.)
NOTE:
Remove the control piston seals when measuring.
Remove the friction ring from the cam ring when mea-
suring.

(2) Using a depth gauge, measure the depth of the oil
pump housing from the contact/sliding surface of the
above mentioned component parts in the same manner
as above.

(3) Make sure that the clearances are within the speci-
fied wear limits. If the wear limit is exceeded, select
pump components so that the standard clearance can
be obtained.
