Note
l
The number of shims used must not exceed three.
9. Select an appropriate adjustment shim to be used for the
differential. It should be selected by referring to the table
and selecting the shim which is nearest (on thick side) to
the largest measured value of the gap in the SST (selector).
Example: 0.54mm (0.021 in)
So the nearest shim (on thick side) to 0.54mm (0.021
in) is 0.6mm (0.014 in).
10. Remove the SST (bolts and collars) and then remove trans-
axle case.
11, Remove the SST (selector), bearing outer race and front
and center differential.
Bearing Preload
Check the shaft gears and the differential bearing preload.
Note
l
Install the diaphragm springs and selected shims.
l
If the bearing preload is not within specification, ad-
just again.
1. Set the primary shaft gear and the front and center differen-
tial assembly into the clutch housing.
2. Install the transaxle case, and tighten to the specified 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.
Note
l
Extend the handle fully and hook the pull scale to
the end of the handle.
4. Hook a spring scale to the attachment and measure the
preload.
Preload:
1.4-2.0 N-m (14-20 cm-kg, 12.2-17.5 in-lb)
