2. Using depth micrometer and straightedge as shown in the fig-
ure, measure dimension "O
2 " between clutch housing end face
and end face of input shaft rear bearing.
3. Install selected input shaft rear bearing adjusting shim onto input
shaft.
MAINSHAFT END PLAY

When adjusting mainshaft end play, select adjusting shim for
mainshaft rear bearing. To select adjusting shim, measure clear-
ance “M” between transaxle case and mainshaft rear bearing.
Refer to MT-102, "
MAINSHAFT REAR BEARING ADJUSTING
SHIM" .
CAUTION:
Only 1 adjusting shim can be selected.

Calculate dimension "P" (thickness of adjusting shim) using the
following procedure to satisfy specification of end play for main-
shaft rear bearing.
1. Install mainshaft assembly to clutch housing.
2. Install snap ring to transaxle case.
3. Install transaxle case to clutch housing, and temporarily assemble them with fixing bolts. Install tempo-
rarily snap ring to mainshaft rear bearing.
4. Install dial gauge to bore plug mounting hole, and expand snap
ring. Lift mainshaft assembly through control assembly installa-
tion hole, and push it against transaxle case. This state shall be
defined as base. Moving distance of mainshaft assembly, with
snap ring fit on main rear bearing, becomes “M”.
DIFFERENTIAL SIDE BEARING PRELOAD

When adjusting differential side bearing preload, select adjust-
ing shim for differential side bearing. To select adjusting shim,
measure clearance “L” between transaxle case and differential
side bearing outer race. Refer to MT-103, "
DIFFERENTIAL
SIDE BEARING ADJUSTING SHIM(S)" .
CAUTION:
Up to 2 adjusting shims can be selected.

Calculate dimension “L” (thickness of adjusting shim) using the
following procedure to satisfy specification of preload for differ-
ential side bearing.

Assembly and Disassembly (RS5F51A)ECS008CA
PRE-INSPECTION

Check the clearance between side gear and differential case as
follows.
1. Clean final drive assembly sufficiently to prevent side gear thrust
washer, differential case, side gear, and other parts from sticking
by gear oil.
2. Upright differential case so that side gear to be measured faces upward.
3. Place the drift below and a dial gauge onto side gear. Move side
gear up and down, and measure the clearance.
CAUTION:
There should be no resistance and gears should rotate
freely.
4. If not within specification, adjust the clearance by changing side
gear thrust washer thickness.
5. Turn differential case upside down, and measure the clearance
between side gear and differential case on the other side in the
same way.
DISASSEMBLY
1. Remove final gear mounting bolts, and then separate the final gear from differential case.
2. Remove differential side bearing (clutch housing side) using the
drift and pullers.
3. Remove differential side bearing (transaxle case side) using the
drift and pullers.

INSPECTION AFTER DISASSEMBLY
Gear, Washer, Shaft and Case

Check side gears, side gear thrust washers, pinion mate shaft,
pinion mate gears, pinion mate thrust washers and differential
