INSPECTION AFTER DISASSEMBLY
Case and Housing
• Check the bearing mounting surface for wear, cracks, and damages. Replace if necessary.
• Check the mating surface for wear, cracks, and damages. Replace if necessary.
• Check the oil seal mounting surface for wear, cracks, and damages. Replace if necessary.
Bearing
Check the bearing for damage and unsmooth rotation. Replace if necessary.
ADJUSTMENT
Differential Side Bearing Preload
• When adjusting differential side bearing preload, select adjusting
shim for differential side bearing. To select adjusting shim
, mea-
sure clearance (L) between transaxle case
and differential side
bearing outer race
. For selecting adjusting shim, refer to the lat-
est parts information.
CAUTION:
Up to 2 adjusting shims can be selected.
• Calculate dimension (L) (thickness of adjusting shim) using the fol-
lowing procedure to satisfy specification of preload for differential
side bearing.
1.
Using a depth micrometer and a straightedge, measure dimen-
sion (L
1
) between transaxle case end face and mounting face of
adjusting shim.
CAUTION:
L
1
: Measure at 4 point by approximately 90 degrees and use
the average value.
2.
Install differential side bearing outer race onto differential side
bearing on transaxle case side. Holding lightly differential side
bearing outer race horizontally by hand, rotate final gear five
times or more (for smooth movement of bearing roller).
3.
Using a depth micrometer and a straightedge as shown in the
figure, measure dimension (L
2
) between differential side bearing
outer race and clutch housing end face.
CAUTION:
L
2
: Measure at 4 point by approximately 90 degrees and use
the average value.

Install selected differential side bearing adjusting shim and then
install differential side bearing outer race (transaxle case side)
using the drift (A) (SST: ST30720000).
CAUTION:
Replace differential side bearing and differential side bear-
ing outer race as a set.
Reverse Idler Gear End Play
• When adjusting reverse idler gear end play, select adjusting shim
for reverse idler gear. To select adjusting shim
, measure clear-
ance between transaxle case
and reverse idler gear (rear)
.
For selecting adjusting shim, refer to the latest parts information.
CAUTION:
Only 1 adjusting shim can be selected.
• Calculate dimension (Q) (thickness of adjusting shim) using the fol-
lowing procedure to satisfy specification of end play for reverse
idler gear.
1.
Using a depth micrometer and a straightedge, measure dimen-
sion (Q
1
) between transaxle case end face and mounting face of
adjusting shim.
2.
Using a depth micrometer and a straightedge as shown in the
figure, measure dimension (Q
2
) between clutch housing
end
face and end face of reverse idler gear (rear)
.
CAUTION:
Q
2
: Measure at 4 point by approximately 90 degrees and
use the average value.

Install selected reverse idler gear adjusting shim onto reverse
idler gear (rear).

TRANSAXLE ASSEMBLY
• 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. For selecting
adjusting shim, refer to the latest parts information.
CAUTION:
Only 1 adjusting shim can be selected.
• Calculate dimension (O) (thickness of adjusting shim) using the fol-
lowing procedure to satisfy specification of end play for input shaft
rear bearing.
1.
Using a depth micrometer and a straightedge, measure dimen-
sion (O
1
) between transaxle case end face and mounting face of
adjusting shim.
CAUTION:
O
1
: Measure at 4 point by approximately 90 degrees and
use the average value.
2.
Using a depth micrometer and a straightedge as shown in the
figure, measure dimension (O
2
) between clutch housing end
face and end face of input shaft rear bearing.
CAUTION:
O
2
: Measure at 4 point by approximately 90 degrees and
use the average value.
3.
Install selected input shaft rear bearing adjusting shim onto input
shaft.
Striking Rod End Play
• When adjusting striking rod end play, select adjusting shim for
striking rod. To select adjusting shim
, measure clearance
between transaxle case
and striking rod shim
. For selecting
adjusting shim, refer to the latest parts information.
CAUTION:
Only 1 adjusting shim can be selected.
• Calculate dimension (R) (thickness of adjusting shim) using the fol-
lowing procedure to satisfy specification of end play for striking
rod.
