Defining thickness of shim "S3*"
WARNING: This page is about a different car, the 2004 Audi A4, 2003 Audi A4, and 2002 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
| Formula: | ||
| "S3*" | = | "Stotal" - "S4*" |
| Example: | ||
| Total shim thickness "Stotal" of "S3" + "S4" |
1.60 mm | |
| - | inserted shim "S4*" | 1.00 mm |
| = | Thickness of shim "S3*" | 0.60 mm |
- Remove outer race of tapered roller bearing, insert shim "S3*" in transmission housing and re-install outer race. See Pressing in outer race for double tapered roller bearing
- Re-insert fully assembled pinion in transmission housing.
- Install transmission cover and tighten bolts to 22 Nm.
- Rotate pinion in same direction and in opposite direction to hollow shaft 5 turns in both directions, so that tapered roller bearings slip into place.
- Install measuring tools and secure with bolt (arrow) to transmission housing.
- Set dial indicator (3 mm measuring range) to "0" with 2 mm pre-load.
- Loosen bolts of transmission cover and turn pinion freely.
If correct shims were selected, the dial indicator should show the following value:
- 0.05 to 0.15 mm
- Tighten bolts of transmission cover to 22 Nm.
- Remove measuring tools.
- Rotate pinion in same direction and in opposite direction to hollow shaft 5 turns in both directions, so that tapered roller bearings slip into place.
