Practical procedure when readjusting the drive set

If it is necessary to adjust drive pinion and ring gear, following this sequence will ensure an efficient working procedure:

1. Determine the total thickness of shims "Stot (Si plus S2). For the specified pretension on tapered roller bearing/differential.

2. Determine the thickness of shim "S3".

3. Split the total thickness "Stot" into Si and S2 so that the specified circumferential backlash is given between ring gear and drive pinion.

The aim of this adjustment is to restore the smoothest running position which can be achieved on test equipment in the production line.

Greatest possible cleanliness when performing all assembly work and measuring procedures are prerequisites for a correct result.

When carrying out assembly work on the final drive assembly, it is only necessary to readjust drive pinion and ring gear or drive set if components have been replaced which have a direct influence on the adjustment. Refer to the following table to avoid unnecessary adjustment work.
