Remove reduction pinion gear from transaxle case.

Measure dimension “D” between the end of reduction pinion
gear and the adjusting shim mating surface of reduction pin-
ion gear.

Measure dimension “D” in at least two places, and take
the average.

Calculate dimension “A”.
e. Measure dimension “E” between the end of idler gear and idler
gear bearing inner race mating surface of idler gear.

Measure dimension “E” in at least two places, and take
the average.
f. Select proper thickness of reduction pinion gear adjusting shim.
Refer to “Parts Information” for reduction pinion gear adjusting
shim selection.
2. Install reduction pinion gear and reduction pinion gear adjusting
shim selected in step 1-f on transaxle case.
CAUTION:
Apply ATF to reduction pinion gear bearing.
3. Press idler gear bearing inner race on idler gear. Refer to AT-
336, "COMPONENTS" .
4. Press idler gear on reduction pinion gear.
CAUTION:

Apply ATF to idler gear bearing.

Press idler gear until idler gear fully contacts reduction
pinion gear bearing adjusting shim.
5. Set manual shaft in “P” position to fix idler gear.
6. Tighten lock nut of idler gear to the specified torque. Refer to AT-257, "
Components" .
CAUTION:
Lock idler gear with parking pawl when tightening lock nut.
7. 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

Completely remove all moisture, oil and old sealant, etc. from the transaxle case and side cover
mounting surfaces.
3. 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.
4. Tighten side cover fitting bolts to specified torque. Refer to AT-
257, "Components" .
CAUTION:

Do not mix bolts A and B.

Always replace bolts A as they are self-sealing bolts.
