Differential Side Bearing Preload

Differential Side Bearing Preload





- When adjusting differential side bearing preload, select adjusting shim for differential side bearing. To select adjusting shim, measure clearance "L" between transaxle case and differential side bearing outer race.
- Calculate dimension "L" (thickness of adjusting shim) using the following procedure to satisfy specification of preload for differential side bearing.
Preload: 0.15 - 0.21 mm (0.0059 - 0.0083 inch)
Dimension "L" = (L1 - L2) + Preload
L: Thickness of adjusting shim
L1: Distance between clutch housing case end face and mounting face of adjusting shim
L2: Distance between differential side bearing and transaxle case





Adjusting Shim

CAUTION: Up to 2 adjusting shims can be selected.





1. Using depth micrometer and straightedge, measure dimension "L1" between clutch housing case end face and mounting face of adjusting shim.
2. Install outer race onto differential side bearing on final gear side. Holding lightly the outer race horizontally by hand, rotate final gear five times or more (for smooth movement of bearing roller).





3. Using depth micrometer and straightedge as shown in the figure, measure dimension "L2" between differential side bearing outer race and transaxle case end face.





4. Install selected adjusting shim and then differential side bearing outer race.
