ADJUSTMENT
Differential Side Bearing Preload

When adjusting differential side bearing preload, select adjust-
ing shim for differential side bearing. To select adjusting shim,
measure clearance “L” between transaxle case and differential
side bearing outer race. Refer to MT-108, "
DIFFERENTIAL
SIDE BEARING ADJUSTING SHIM(S)" .
CAUTION:
Up to 2 adjusting shims can be selected.

Calculate dimension “L” (thickness of adjusting shim) using the
following procedure to satisfy specification of preload for differ-
ential side bearing.
1. Using depth micrometer and straightedge, measure dimension
“L
1 ” between transaxle case end face and mounting face of
adjusting shim.
2. Install differential side bearing outer race onto differential side
bearing on final gear side. Holding lightly differential side bear-
ing outer race horizontally by hand, rotate final gear five times or
more (for smooth movement of bearing roller).
