27. Tighten the bolts of the transaxle housing in the
same manner as in step 22.
Tighten
Tighten the bolts to 29 NSm (22 lb–in).
28. Using differential preload adapter DW240–130, turn
the differential gear assembly right and left 2 or 3
times to allow the bearing settle.
29. Using differential preload adapter DW240–130 and
a small torque wrench, measure the preload of the
differential gear. From this valve deduct the valve
measured in step 23. This is the preload of the
counter driven gear.
S Preload:
New bearing: 0.33–0.76 NSm (3.21–6.77 lb–in)
Used bearing: 0.17–0.38 NSm (1.48–3.39 lb–in)

91. Apply formed in place gasket (FIPG) to the trans-
axle rear cover.
FIPG: three bond 1281 or equivalent
Seal bend width: 1.2 mm (0.047 in.)
92. Install the transaxle rear cover to the transaxle case
with the 9 bolts.
Tighten
Tighten the bolts to 25 NSm (18 lb–ft).
93. Install the counter driven gear assembly to the
transaxle case.
94. Install the differential gear assembly to the trans-
axle case.

5. Using a suitable puller, remove the tapered roller
bearing of transaxle case side.
6. Using a pin punch and hammer, drive out the pin
from the ring gear side.
7. Remove the differential pinion shaft from the case.
8. Remove the 2 differential pinion gears, 2 differential
side gears, 2 differential pinion thrust washers and
2 differential side gear thrust washers.

Assembly Procedure
1. Using transaxle housing side bearing outer race
adapter DW240–140 and adapter handle
DW240–170, install a new side bearing outer race
into the transaxle housing.
2. Install the shim to the transaxle case.
Notice : First install a shim of the same thickness as be-
fore.
3. Install a new side bearing outer race into the trans-
axle case.
4. Coat the thrust washers, side gears, pinion gears
and pinion thrust washers with ATF.
5. Install the 2 differential side gear thrust washers to
2 differential side gears.
6. Install the 2 side gears with 2 thrust washers, 2 pin-
ion gears and 2 pinion thrust washers into the dif-
ferential case.
7. Coat the pinion shaft with ATF.

8. Install the pinion shaft so as to align the lock pin
holes on the pinion shaft and differential case.
9. Measure the side gear backlash while holding 1
pinion gear toward the case.
S Standard backlash:
0.05
0.20 mm (0.0020–0.0079 in.)
If the backlash is out of specification, install the
correct thrust washer to the side gear.
10. Referring to the table below, select thrust washers
which will ensure that the backlash is within the
specification.
Try to select washers of the same size for both
sides.
Thrust washer thickness : mm (in.)

1.00 (0.0394)1.15 (0.0453)
1.05 (0.0413)1.20 (0.0472)
If the backlash is not within the specification,
install a thrust washer of a different thickness.
11. Using a hammer and punch, drive in the pin
through the case and hole in the pinion shaft.

12. Using a hammer and chisel, stake the differential
case.
13. Using a press, install the tapered roller bearing into
the differential case.
14. Using a press, install the tapered roller bearing into
the differential case.
15. Remove any formed in place gasket (FIPG) materi-
al and be careful not to get oil on the contacting
surfaces of the transaxle housing or transaxle case.
16. Install the differential to the transaxle case.

17. Install the transaxle housing and 16 bolts of the
transaxle housing temporarily.
18. Tighten 8 or 9 bolts out of 16 bolts of the transaxle
housing completely.
Tighten
Tighten the bolts to 29 NSm (22 lb–ft).
19. Using differential preload adapter DW240–130, turn
the differential gear assembly right and left 2 or 3
times to allow the bearing settle.
20. Using differential preload adapter DW240–130 and
small torque wrench, measure the preload of the
differential gear.
S Preload:
New bearing: 0.78–1.37 N.m (6.9–12.2 lb –in)
Used bearing : 0.39–0.69 N.m (3.5
6.1 lb–in)
If the preload is not within the specification, re-
move the differential from the transaxle case.
Re–select the transaxle case side adjusting
shim according to the following table.
