2. Adjust the differential side bearing preload
Note
To inspect and adjust the preload, use
(15) Install the bearing housing.
Tightening torque:
19—26 Nm (1.9—2.6 m-kg, 14—19 ft-lb)
(16) Check that the preload/pull scale reading
is within specification. If not within specifi-
cation return to step (2).
Preload: 0.03—0.9 N-m
(0.3—9.0 cm-kg, 0.26—7.81 in-lb)
Reading on pull scale:
0.3—9 N (0.03—0.9 kg, 0.066—1.98 lb)

(1) Remove the bearing outer race and adjust
shims from the transaxle case. (Refer to page
7B—106)
(2) Set the differential assembly into the convert-
er housing.
(3) Install the outer race removed in step (1) into
the SST; then set them on the differential as-
sembly.
Caution
Eliminate the gap by turning either A or B of
the selector.
(4) Set the six SST in the positions shown.
Note
Install the bolts in the positions shown in the
illustration above.
83U07B-383
(5) Set the transaxle case on the selectors.
(6) 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) 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 un-
til the preload is eliminated (gap is reduced).
(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 0.3 mm (0.0118 in) to the measured
clearance, and select the shim(s) closest in
valve to that measurement.

the maximum clearance.
b)The maximum allowable number of shims
is 3.
