Gears
1. Inspect synchronizer cones for wear.
2. Inspect individual gear teeth for damage, wear, and cracks.
3. Inspect synchronizer ring matching teeth for damage and
wear.

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.
