(5) Install the outer race removed in step (3) to the
SST; then mount them on the output gear as-
sembly.
Caution
Eliminate the gap (arrow) by turning A or B of
the selector.
76G07C-233
(7) Set the bearing housing on the SST (selector)
and install the four SST (bolts); then tighten
them to the specified torque,
Tightening torque:
19—26 N m (1.9—2.6 m-kg, 14—19 ft-lb)
76G07C-234
(8) Turn the SST (selector) to increase the clear-
ance (indicated by the arrow) with the SST
(bars) until it no longer turns.
Note
This is to seat the bearing.
(9) Turn the selector in the opposite direction un-
til the preload is eliminated (gap is reduced).

7C ASSEMBLY
(10) Mount the SST and pull scale or torque
wrench on the output gear.
(11) Increase the clearance between A and B
to obtain the specified preload/pull scale
reading.
Preload: 0.5—0.9 N-m
(5.0—9.0 cm-kg, 4.34—7.81 in-lb)
Reading on pull scale: 5—9 N
(0.5—0.9 kg, 1.1—1.98 lb)
Note
Read the preload when the output gear starts
to turn.
(12) Measure the clearance. Select adjust
shim(s) equivalent to the measured
clearance.
Thickness of shim
0.10 mm (0.004 in) 0.12 mm (0.005 in) 0.14 mm (0.006 in)
0.16 mm (0.0063 in) 0.20 mm (0.008 in) 0.50 mm (0.020 in)
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 7.

(13) Remove the bearing housing and SST.
(14) Install the required shim(s) and press the
bearing race into the bearing housing with
a suitable pipe.
(15) Install the bearing housing.
Tightening torque:
19—26 N m (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 (3).
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)
(17) Remove the bearing housing and output
gear assembly.
2. Mount the side bearing housing to transaxle case
by gradually tightening the mounting bolts in a di-
agonal pattern.
Tightening torque:
19—26 N-m (1.9—2.6 m-kg, 14—19 ft-lb)

(4) Set the six SST in the positions shown.
83U07B-382
Note
Install the bolts in the positions shown in the
illustration above.

(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).

(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.
