ADJUSTMENT
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-108, "
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.
1. Using depth micrometer and straightedge, measure dimension
“L
1 ” between transaxle case end face and mounting face of
adjusting shim.
2. Install differential side bearing outer race onto differential side
bearing on final gear side. Holding lightly differential side bear-
ing outer race horizontally by hand, rotate final gear five times or
more (for smooth movement of bearing roller).
3. Using depth micrometer and straightedge as shown in the fig-
ure, measure dimension “L
2” between differential side bearing
outer race and clutch housing end face.
4. Install selected differential side bearing adjusting shim, and then
install differential side bearing outer race using the drift.Preload: 0.15 - 0.21 mm (0.0059 - 0.0083 in)

Reverse Idler Gear End Play
When adjusting reverse idler gear end play, select adjusting
shim for reverse idler gear. To select adjusting shim, measure
clearance between transaxle case and reverse idler gear. Refer
to MT-107, "
REVERSE IDLER GEAR ADJUSTING SHIM" .
CAUTION:
Only 1 adjusting shim can be selected.
Calculate dimension “Q” (thickness of adjusting shim) using the
following procedure to satisfy specification of end play for
reverse idler gear.
1. Using depth micrometer and straightedge, measure dimension
“Q
1” between transaxle case end face and mounting face of
adjusting shim.
2. Using depth micrometer and straightedge as shown in the fig-
ure, measure dimension “Q
2” between clutch housing end face
and end face of reverse idler gear (Rear).
3. Install selected reverse idler gear adjusting shim onto reverse
idler gear assembly.
Input Shaft End Play
When adjusting input shaft end play, select adjusting shim for
input shaft rear bearing. To select adjusting shim, measure
clearance between transaxle case and input shaft rear bearing.
Refer to MT-107, "

SHIM" .
CAUTION:
Only 1 adjusting shim can be selected.
Calculate dimension “O” (thickness of adjusting shim) using the
following procedure to satisfy specification of end play for input
shaft rear bearing.End play: 0.04 - 0.10 mm (0.0016 - 0.0039 in)
