Determining adjustment shim
WARNING: This page is about a different car, the 2004 Volkswagen R32. However, it is still accessible from the selected car via links, so may be relevant.
The specified bearing pre-load is obtained by adding a constant pre-load figure of (0.30 mm) to the reading obtained.
Example:
| Measured value | 0.70 mm |
| + pre-load (const. value) | 0.30 mm |
| Thickness of adjustment shim = | 1.00 mm |
- Remove transmission housing.
- Pull outer race/tapered roller bearing out of transmission housing.
A - Support , e.g. Kukko 22/2
B - Internal puller 46 to 58 mm , e.g. Kukko 21/7
- Determine thickness of adjustment shim according to table.
- Determine replacement part number of adjustment shim according to Electronic Parts Catalog (ETKA).
- Insert adjustment shim of determined thickness, thickest shim first.
The following adjustment shims are available:
| Shim thickness (mm) | |||
| 0.65 | 0.85 | 1.05 | 1.25 |
| 0.70 | 0.90 | 1.10 | |
| 0.75 | 0.95 | 1.15 | |
| 0.80 | 1.00 | 1.20 | |
If the measured shim thickness is greater than listed in the table, 2 shims corresponding to the measured value can be installed.
Different tolerances make it possible to measure the required shim size exactly.
- Press in outer race again and tighten transmission housing to tightening torque.
