(3) Install the oil pump housing assembly to the torque
converter clutch case, and secure evenly by tightening
four bolts.
Tightening torque:
41±3 N⋅m (4.2±0.3 kg-m, 30.4±2.2 ft-lb)
CAUTION:
Thoroughly remove the liquid gasket from the case
mating surface beforehand.
Use an old gasket or an aluminum washer so as not
to damage the mating surface of the housing.

(4) Rotate the drive pinion several times with ST1 and
ST2.

(5) Tighten the LH retainer until contact is felt while
rotating the shaft. Then loosen the RH retainer. Keep
tightening the LH retainer and loosening the RH
retainer until the pinion shaft can no longer be turned.
This is the“zero”state.
G3M0885
(6) After the“zero”state is established, back off the LH
retainer 3 notches and secure it with the lock plate.
Then back off the RH retainer and retighten until it
stops. Repeat this procedure several times. Tighten the
RH retainer 1-3/4 notches further. This sets the preload.
Finally, secure the retainer with its lock plate.
NOTE:
Turning the retainer by one tooth changes the backlash
about 0.05 mm (0.0020 in).

(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.]

Face contact
Backlash is too large.This may cause noise and chipping at
tooth ends.

Flank contact
Backlash is too small.This may cause noise and stepped wear
on surfaces.

Reduce thickness of drive pinion height
adjusting shim in order to move drive pin-
ion away from crown gear.
