A6 Quattro Sedan V6-2.8L (AHA) (1998)
R - Actual dimension between ring gear axis and face of drive pinion in position of quietest running for this gear set:
R = Ro + r
Vo - Hypoid offset
Gear set, adjusting sequence
If drive pinion and gear ring have to be adjusted, the following sequence is recommended for maximum efficiency:
1.) Determine total shim thickness "Stot" for S1 + S2 for the specified pretension of tapered roller bearings for differential.
2.) Determine total shim thickness "S3" so that the drive pinion is installed in the same location as on the test machine during production.
3.) Distribute total shim thickness Stotal (S1 + S2), so that the specified backlash between ring gear and drive pinion is maintained.
