Procedure if there is bearing oversize
WARNING: This page is about a different car, the 2015 Audi S7, 2015 Audi RS 7, 2014 Audi S7, 2014 Audi RS 7, and 2013 Audi S7. However, it is still accessible from the selected car via links, so may be relevant.
-- Place Straight Edge - 500mm VAS6075 straight across the bearing and determine the distance to the contact surface on the transmission housing on both sides with the feeler gauge.
-- Write down the measured value.
-- Place the straight edge 90° offset across the bearing and determine the distance to the contact surface on the transmission housing on both sides with the feeler gauge.
-- Write down the measured value.
Selecting the Shim(s):
NOTE:
Use the smallest value take from the four values to select the shim(s).
- Specified value, bearing oversize = 0.5 to 0.8 mm
| Smallest bearing oversize (example = 0.1 mm) | |
| + | Shim(s) thickness, (thickness = 0.3 mm) |
| = | Bearing pre-load, (specified value = 0.5 to 0.8 mm) |
Example:
1 shim:
0.1 mm + 0.3 mm = 0.4 mm, "bearing pre-load is too small"
2 shims:
0.1 mm + 0.3 mm + 0.3 mm = 0.7 mm, "bearing pre-load is in the specified range"
- Result: Insert two 0.3 mm shims to reach the bearing pre-load = 0.7 mm within the 0.5 to 0.8 mm specified value.
