Note
l Turn the bars until the SST (selector) can no longer
be moved.
6. To seat the bearings, mount the bars on parts @ and @I
of the selector, and turn the selector so the gap is widened.
7. Turn in the reverse direction until the gap is eliminated.
8. Install the
SST to the differential pinion gear through the
transaxle case.
9. Turn the
SST with a torque wrench. Adjust the SST (selec-
tor) with the bars until the specified preload is obtained.
Preload:
0.03-0.74 N#m (0.3-7.6 cm-kg, 0.26-6.60 in-lb)
10. Remove the SST.
11. Measure the clearance around the entire circumference of
the
SST (selector).
12. Select the proper adjust shim(s) to be used for the differen-
tial by referring to the table and selecting the shim which
is nearest (on the thick side) to the largest measured clear-
ance in the selector.
