Bearing Preload
Check the shaft gears and the differential bearing
preload.
Note
a) Check that the correct adjust shims were
selected.
b) If the bearing preload is not within specifi-
cation, adjust again.
1. Set the primary shaft gear and the differential into
the clutch housing.
2. Install the transaxle case, and tighten to the speci-
fied torque.
Tightening torque: 37—52 N-m
(3.8—5.3 m-kg, 27—38 ft-lb)
3. Connect the SST and install it through the
driveshaft hole.
4. Measure the preload.
Preload: 1.4—2.0 N-m
(14—20 cm-kg, 12.1—17.3 in-lb)
5. Remove the SST.
6. 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)
76G07A-046
8. Remove the SST, transaxle case, primary shaft
gear and differential.
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)
10. Check the secondary shaft preload with the SST.
Preload: 0.2—0.4 N-m
(2.0—4.0 m-kg, 1.7—3.4 in-lb)

1. Install the magnet and the differential assembly.
2. Install the primary shaft gear assembly and the
secondary shaft gear assembly together.
3. Shift to 2nd gear and position the shift fork and shift
rod assembly as shown.
Insert the spring seat and spring into the reverse
lever shaft, install the steel ball, and place a scraper
knife so that it contacts the steel ball.
With the edge of the control end against the knife,
when the control end is pushed in the direction of
the arrow in the figure so that the ball goes into
the shaft, the rod will at the same time line up with
the shift rod coupling hole in the clutch housing.
6. Set each clutch hub sleeve to the neutral position,
and tap the shift rod from above so that the steel
ball goes into the center groove (of the 3 grooves
in the control end).
7. Pull the ball part of the control end forward so that
the steel ball goes into the detent in the groove.

8. Fit the crank lever in between the change arm and
the control end, and connect the crank lever shaft
to the crank lever.
9. Align the pin holes of the crank lever shaft and the
clutch housing, and insert the pin.
Note
Use a new O-ring for the crank lever shaft.

10. Install the gate © and the shift rod ©, and tight-
en the gate mounting bolt.
Note
The mark (indicated by the arrow in the fig-
ure) and the gate mounting bolt hole must be
in the same direction.

11. Install the reverse idle gear and the reverse idle
shaft.
12. Connect the magnet to the clutch housing.
13. Align the end of the interlock sleeve with the con-
trol lever indicated by the arrow, and, at the same
time, face the reverse idle shaft screw hole in the
direction shown in the figure.
76U07A-122
14. Apply a thin coat of sealant to the contact surfaces
of the clutch housing and transmission case, tight-
en the transaxle case installation bolts to the speci-
fied torque.
Tightening torque:
18—26 N m (1.8—2.7 m-kg, 13—18.8 ft-lb)
15. Insert the SST to driveshaft coupling hole.
