(2) Tighten four bolts to secure the roller bearing.
Tightening torque:
39 ± 3 N·m (4.0 ± 0.3 kg-m, 28.9 ± 2.2 ft-Ib)

(3) Install the oil pump housing assembly to the con-
verter case, and secure evenly by tightening four bolts.
Tightening torque:

a. Thoroughly remove the liquid gasket from the case mating
surface beforehand.
b. Use an old gasket or an aluminium washer so as not to
damage the mating surface of the housing.
(4) Rotate the drive pinion several times.

(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.
(6)
After the "zero" state is established, back off the LH
retainer
3
notches and secure it with the locking tab. 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 locking tab.
Turning the retainer by one tooth changes the backlash about
0.05 mm (0.0020 in).
(7)
Turn the drive pinion several rotations and check
to see if the backlash is within the standard value.
Backlash:
0.13 - 0.18 mm (0.0051 - 0.0071 in)
After confirming that the backlash is correct, check the
tooth contact.
