b. Move side gear up and down to measure dial indicator deflec-
tion. Always measure indicator deflection on both side gears.
c. If not within specification, adjust clearance by changing thick-
ness of differential side gear thrust washers. Refer to “Parts
Information” for side gear thrust washers selection.
4. Install lock pin with pin punch.
CAUTION:

Do not reuse lock pin.

Make sure that lock pin is flush with differential case.
5. Press on differential side bearings.
CAUTION:
Apply ATF to differential side bearings.
6. Install differential side bearing outer race and differential side
bearing adjusting shim on transaxle case. Refer to AT- 3 4 0 ,
"Adjustment (1)" .
7. Tighten final gear and tighten fixing bolts to the specified torque
in numerical order as shown in the figure after temporarily tight-
ening them. Refer to AT- 3 3 5 , "

3. Install reduction pinion gear and reduction pinion gear bearing
adjusting shim selected in step 2-e on transaxle case.
4. Press idler gear bearing inner race on idler gear. Refer to AT-
337, "ASSEMBLY" .
5. Press idler gear on reduction pinion gear.
CAUTION:
Press idler gear until idler gear fully contacts adjusting
shim.
6. Set manual shaft to “P” position to fix idler gear.
7. Tighten idler gear lock nut to the specified torque. Refer to AT-
246, "Components" .
CAUTION:
Lock idler gear with parking pawl when tightening lock nut.
8. Measure turning torque of reduction pinion gear.

When measuring turning torque, turn reduction pinion
gear in both directions several times to seat bearing roll-
ers correctly.

If turning torque is out of specification, decrease or
increase thickness of reduction pinion gear adjusting
shim.
9. After properly adjusting turning torque, clinch idler gear lock nut
as shown.
CAUTION:
Do not reuse idler gear lock nut.

4. Measure dimensions “1 ” and “2 ” at side cover and then cal-
culate dimension “A”.

Measure dimension “ 1” and “ 2” in at least two places.
5. Measure dimensions “
2 ” and “3 ” and then calculate dimen-
sion “B”.

Measure dimension “ 2” and “ 3” in at least two places.
6. Select proper thickness of output shaft adjusting shim so that
output shaft end play (clearance between side cover and output
shaft bearing) is within specifications. Refer to “Parts Informa-
tion” for output shaft adjusting shim selection.
7. Install output shaft adjusting shim on output shaft bearing.

1. Apply locking sealant (Loctite # 518) to transaxle case as shown
in figure.
CAUTION:
Completely remove all moisture, oil and old sealant, etc.
from the transaxle case and side cover mounting surfaces.
2. Fit mounting part of output shaft bearing on side cover to output
shaft bearing, and after adjusting knock pin position, install it
with light taps of a soft hammer and things like that.
CAUTION:
When installing, to avoid getting damaged and deformed,
set mounting part straight to parallel with the mounting sur-
face.“A”: Distance between transaxle case fitting sur-
