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 the clearance by changing the
thickness of differential side gear thrust washers. Refer to AT-
535, "Final Drive" .
4. Install lock pin.
CAUTION:

Do not reuse lock pin.

Make sure that lock pin is flush with 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- 5 0 8 ,
"Adjustment (1)" .
7. Tighten final gear and tighten fixing bolts to the specified torque
in numerical order shown in the figure after temporarily tighten-
ing them. Refer to AT- 5 0 3 , "
COMPONENTS" . Clearance between side gear and differential case
with washer:
0.1 - 0.2 mm (0.004 - 0.008 in)

6. Set manual shaft to “P” position to fix idler gear.
7. Tighten idler gear lock nut to the specified torque. Refer to AT-
416, "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 the thickness of reduction pinion gear bearing
adjusting shim.
9. After properly adjusting turning torque, clinch idler gear lock nut
as shown.
CAUTION:
Do not reuse idler gear lock nut.
OUTPUT SHAFT END PLAY

Measure the clearance between side cover and the end of the
output shaft bearing.

Select proper thickness of output shaft adjusting shim so that
clearance is within specifications.

7. Install output shaft adjusting shim on output shaft bearing.
Assembly (2)ECS004MF
1. Apply locking sealant (Locktite #518) to transaxle case as
shown in illustration.
2. Fit the mounting part of output shaft bearing on side cover to
output shaft bearing, and after adjusting knock pin position,
install it with light taps using a soft hammer and things like that.
CAUTION:
When installing, to avoid getting damaged and deformed,
set the mounting part straight to parallel with the mounting
surface.
3. Tighten side cover fixing bolts to specified torque. Refer to AT-
416, "Components" .
CAUTION:

Do not mix bolts A and B.

Always replace bolts A as they are self-sealing bolts.Output shaft end play (A − B):
0 - 0.15 mm (0 - 0.0059 in)
