Determining Shim Thickness
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2010 Volkswagen Jetta, 2009 Volkswagen Jetta, 2009 Volkswagen GLI, 2008 Volkswagen Jetta, and 2008 Volkswagen GLI. However, it is still accessible from the selected car via links, so may be relevant.
The required bearing tension is reached as follows:
The specified bearing preload is reached when the determined measured value (0.14 mm) is subtracted from the inserted adjustment shim (1.70 mm).
A constant figure of (0.40 mm) is added to the reading.
Example:
| Inserted adjusting shim | 1.70 mm |
| - measured value | 0.14 mm |
| + Preload (constant value) | 0.20 mm |
| Adjusting shim thickness | 1.76 mm |
-- Select the correct adjusting shim thickness according to the table. Refer to ADJUSTMENT SHIM TABLE .
-- Remove the transmission housing and remove the tapered roller bearing outer race from the transmission housing.
A - Counter-support, for example, kukko support 22/2
B - Internal puller 46 to 58 mm, for example, kukko extractor 46-58 mm 21/7
-- Remove the adjusting shim (1.70 mm) from the transmission housing.
