2. Machine cylinder head inner diameter at valve seat installation
position.
3. Heat cylinder head to approximately 110 to 130°C(230to
266°F) in oil bath.

3. Measure the side gear endplay following the procedure below,
and select the appropriate side gear thrust washers.
lUsing a thickness gauge, measure the clearance between
side gear back and the differential case at 3 different points,
while rotating the side gear. Average the 3 readings, and
select the appropriate side gear thrust washer so that the
mean value is within specifications below. (Measure the clear-
ance of the other side as well.)
CAUTION:
lBefore measurement, place differential case straight up
so that side gear to be measured comes upward. To pre-
vent the side gear from tilting, insert thickness gauges
with the same thickness from both sides.
lSelect a side gear thrust washer for right and left individ-
ually.
4. Assemble the selected side gear thrust washer to the differential
case.
5. Using a pin punch, drive a lock pin into the pinion mating shaft.
CAUTION:
Do not reuse the lock pin.
6. Using a drift, press a side bearing inner race into the differential
case.
7. Apply locking sealant (Thread lock super 1303 or equivalent) onto the thread of the drive gear.
CAUTION:
The drive gear back, threaded holes, and drive gear bolts shall be cleaned and decreased suffi-
ciently.
8. Assemble the drive gear to the differential case. Apply anti-corrosive oil onto threads and seats of the
drive gear bolts, and tighten to the specified torque.Side gear endplay standard:
0.2 mm (0.008 in) or less. Every gear shall rotate
smoothly with no abnormal feeling of drag.
