Shim, Determining
WARNING: This page is about a different variant/trim than selected.
The specified bearing pre-load is obtained by adding a constant pre-load figure of 0.25 mm to the reading obtained.
Example:
Measured value 0.70 mm
+ Preload (constant value) 0.25 mm
Shim thickness = 0.95 mm
Example:

NOTE:
Allocate the shims. Refer to the Parts Information.
- Remove the transmission housing and remove the tapered roller bearing outer race from the transmission housing.
- Counter Support, for example, -22/2-
- Internal Puller 46 to 58 mm, for example, -21/7-
If the measured shim thickness is larger than those listed in the Table, then install two shims that add up to the necessary thickness.
- Install the shim with the correct thickness, thickest shim first.
Tolerance variations make it possible to find the exact shim thickness required.
- Install the outer race/tapered roller bearing with the selected shim (in the example: 0.95 mm) and tighten the transmission housing.
- Support the transmission housing with the -3144- directly under the bearing mount.
