7) Measure dimension “B” of the drive pinion shaft
ST 398643600 GAUGE
8) Calculate the thickness “t” (mm) of the drive pin-
ion shim.
t = 6.5 ± 0.0625 – (B – A)
9) Select three or less shims from following table.
E: INSPECTION
•Make sure that all component parts are free of
scratches, holes and other faults.
•Adjust the tooth alignment.
F: ADJUSTMENT
1) Remove the liquid gasket from the mating sur-
face completely.
2) Install the converter case to oil pump cover, and
secure them with tightening four bolts evenly.
NOTE:
Use an old gasket or aluminum washer to prevent
damaging the mating surface of the housing.
Tightening torque:
41 N·m (4.2 kgf-m, 30.4 ft-lb)
3) Rotate the drive pinion a few times using ST1
and ST2.
ST1 18667AA010 HOLDER
ST2 499787700 WRENCH
4) Adjust the drive pinion and hypoid driven gear
backlash.
5) Apply red lead evenly to the surfaces of three or
four teeth on hypoid driven gear. Rotate the drive
pinion in the leftward and rightward for several
times. Remove the oil pump cover, and check the
tooth contact pattern.
If the teeth contact is inappropriate, adjust the
backlash or thickness of the shim.
•Correct tooth contact
Check item: Tooth contact surface is slightly
shifted toward the toe side under a no-load con-
dition. (When driving, it moves towards the heel
side.)

between two bevel gear teeth.
•Fix the bevel pinion gear in place with a screw-
driver or similar tool when measuring.
Specification:

lect a washer from the table below.

6) Tighten the LH retainer by rotating the shaft until
resistance is felt. Then loosen the retainer RH.
Keep tightening the retainer LH, and loosening the
retainer RH until the pinion shaft no longer be
turned. This is the “zero” state.
7) After the “zero” state is established, back off the
retainer LH 3 notches and secure it with the lock
plate. Then back off the retainer RH and retighten
until it stops. Rotate the drive pinion 2 or 3 times.
Tighten the retainer RH further 1-3/4 notches. This
sets the preload. Finally, secure the retainer with its
lock plate.
NOTE:
Turning the retainer by one tooth changes the
backlash approx. 0.05 mm (0.0020 in).
8) Turn the drive pinion several times using ST1,
and check to see if the backlash is within the spec-
ification using ST2, ST3, ST4 and ST5.
