Bearing outer race (transaxle case)
Note
l Since removing the bearing outer race is difficult,
use the SST.
1. Remove the bearing outer race.
Bearing outer race (secondary shaft)
1. Remove the bearing outer race by lifting out the funnel and
race together.
Roll pin
1. Align the groove for removal of the clutch housing pin with
the position of the roll pin, then tap the pin out using a pin
punch.
Bearing outer race (differential)
Caution
l Hold the SST with one hand so that it does not fall.
1. Remove the bearing outer race with a press.
Oil seal (differential)
Replacement (On-vehicle)
Jack up the vehicle and support it with safety stands. Drain
the transaxle oil. Next, use the following procedure to replace
the driveshaft oil seal:
1. Remove the front wheel.
2. Remove the splash shield.
3. Separate the front stabilizer from the lower arm.

into the transaxle case (diaphragm springs and shims
removed).
2. Mount the clutch housing onto the transaxle hanger, and
set the differential bearing outer race into the clutch housing.
Position a piece of pipe against the outer race and tap in
with a hammer until it contacts the clutch housing.
3. Set the outer races into the
SST (selector) as shown in the
figure.
Note
l Turn the selector to eliminate the gap indicated by
the arrow in the figure.
4. Set the differential assembly into the clutch housing; then
set the bearing outer race and the
SST (selector) on the
differential. Set the assembled selectors for the primary and
secondary shaft in the clutch housing.
Mount the shaft gear assemblies as shown in the figure.
5. Set the
SST (collars) in the positions shown in the figure.
6. Install the transaxle case and tighten the
SST (bolts) to the
specified torque.
Tightening torque:
37-52 N#m (3.8-5.3 m-kg, 27-38 ft-lb)
7. To seat the bearings, mount the SST (bars) on parts @and
@of the selector, and turn the selector so the gaps are
widened.
Then turn the
SST in the reverse direction until the gaps
are eliminated.

Caution
l Measure the gap around the entire circumference
of the selector
13. Use a feeler gauge to measure the gap in the selector for
the differential.
14. Add 0.15mm (0.0059 in) to the measured clearance and
select the combination of shims closest in value to that meas-
urement.
Note
l Use a maximum of two shims.
See the table below for available shim sizes.
Example: 0.32mm (0.013 in)
0.32mm (0.013 in) + 0.15mm (0.006 in) = 0.47mm
(0.019 in).
So the nearest shim (on the thick side) to 0.47mm
(0.019 in) is 0.50mm (0.020 in).
15. Remove the SST and the transaxle case.
16. Remove the selectors, the primary shaft assembly and the
-differential.
17. Remove the bearing outer races.
Assembly note
Oil seals
1. Apply transaxle oil to outer periphery.
2. Install the new oil seals with the SST.
Diaphragm spring
1. Install the diaphragm spring as shown in the figure.
Boot
1. Install the boot with the drain hole facing downward.

1. Set the primary shaft gear and the differential into the clutch
housing.
2. Install the transaxle case, and tighten to the specified torque.
Tightening torque:
37-52 N.m (3.8-5.3 m-kg, 27-38 f&lb)
3. Connect the SST and install it through the driveshaft hole.
4. Hook a spring scale to the attachment and measure the
preload.
Preload:
1.4-2.0 N.m (14-20 cm-kg, 12-17 in-lb)
5. Remove the SST.
6. With the transaxle facing in the direction shown in the fig-
ure, install the
SST to the primary shaft gear.
7. Measure the preload.
Preload:
0.1-0.25 N-m (1.0-2.5 cm-kg, 0.87-2.18 in-lb)
8. Remove the SST, transaxle case, primary shaft gear and

9. Install the secondary shaft gear and transaxle case then
tighten to the specified torque.
Tightening torque:
37-52 N-m (3.8-5.3 m-kg, 27-38 ft-lb)
