NOTE:
Apply oil to the oil seal lips.
3) Install a new O-ring.
E: INSPECTION
• Check each component for scratches, damage
or other faults.
• Measure the backlash, and then adjust it within
specification.
<Ref. to 5AT-95, ADJUSTMENT, Front Differential
Assembly.>
F: ADJUSTMENT
1) Using the ST, screw-in the retainer until resis-
tance is felt.
NOTE:
Screw-in the RH side slightly deeper than the LH
side.

2) Remove the oil pump cover.
3) Remove the liquid gasket from the mating sur-
face completely.
4) Install the oil pump cover to converter case, and
secure them with tightening four bolts evenly.
NOTE:
Use an old gasket or aluminum washer so as not to
damage the mating surface of housing.

6) Tighten the retainer LH 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 to the “zero” state.
7) After the “zero” state is established, back off the
retainer LH three notches and secure it with the
lock plate (A). Then back off the retainer RH and re-
tighten until it stops. Rotate the drive pinion two to
three 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.
