Sequence of Adjustments


If the pinion and ring gear have to be adjusted, it is important to comply with the following sequence in the interest of a streamlined work process.
- Determine total shim thickness "Stotal," (S1 plus S2) for specified pre-load for tapered roller bearing/differential gear.
- Determine shim thickness S3 so pinion will be installed in position determined in production on special test machine.
- Distribute total shim thickness "Stotal," (S1 plus S2) such that specified backlash is present between ring gear and pinion.

The goal of the adjustment is to again achieve the position of quietest operation that was determined on the test machine in production.

The greatest possible care and cleanliness during all installation work and measuring procedures are absolutely necessary for a satisfactory result.
