(4) Set the six SST in the positions shown.
83U07B-382
Note
Install the bolts in the positions shown in the
illustration above.
76G07C-244
(5) Set the transaxle case on the selectors.
(6) Tighten the SST (bolts) to the specified torque.
Tightening torque:
29—46 Nm (3.0—4.7 m-kg, 22—34 ft-lb)
76G07C-245
(7) Turn the SST (selector) to increase the clear-
ance (indicated by the arrow) with the SST
(bars), until it no longer turns.
Note
a )This is to seat the bearings.
b )To turn the SST (B), bend the bar as shown.
(8) Turn the selector in the opposite direction until
the preload is eliminated (gap is reduced).

7C ASSEMBLY
(9) Insert the SST through the oil seal hole of the
transaxle case and attach
it
to the pinion shaft.
(10) Mount the SST and pull scale or torque
wrench.
(11) Widen the clearance between A and B to ob-
tain the specified preload/pull scale reading.
Preload:
0.5 N-m (5 cm-kg, 4.3 in-lb)
Reading on pull scale: 5 N (0.5 kg, 1.1 lb)
Note
Read the preload when the differential starts
to turn.
(12) Measure the clearance between A and B.
(13) Add 0.15 mm (0.0059 in) to the measured
clearance, and select the shim(s) closest in
valve to that measurement.

Caution
a) Measure the clearance around the entire cir-
cumference, and select shims equivalent to
the maximum clearance.
b)The maximum allowable number of shims
is 3.
(14) Remove the transaxle case and selector.
(15) Install the required shim(s) and tap the bear-
ing race into the side bearing housing.

(16) Install the transaxle case.
Tightening torque:
29—46 N-m (3.0—4.7 m-kg, 22—34 ft-lb)
(17) Check that the preload is within specification.
If not within specification, return to step (2).
Preload: 2.1—3.0 N-m
(21—31 cm-kg, 18—27 in-lb)
Reading on pull scale: 20—30 N
(2.1—3.1 kg, 4.6—6.8 lb)
(18) Remove the transaxle case.
3. Install the idle gear and output gear as an assem-
bly by tapping in with a plastic hammer.

4. Install the bearing housing.
(1) Mount the bearing housing onto the convert-
er housing.
Tightening torque:
19—26 N-m (1.9—2.6 m-kg, 14—19 ft-lb)
(2) Align the groove on the idle shaft as shown.
(3) Tap the roll pin in with a pin punch and
hammer.
