Procedure If There Is Bearing Oversize
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Audi S5, 2014 Audi S5, 2013 Audi S5, 2012 Audi S5, and 2011 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.
-- Place VAS 6075 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 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.
