- Mount magnetic plate (020b) 116 589 01 21 00 part 04 on the end face of the drive pinion to measure the adjustment dimension "A" .
- Install measuring device (020a) 116 589 01 21 00 part 01 together with gauge stand (022) and dial gauge in the left bore of the rear axle housing.
- Read off adjustment dimension "A"
. The adjustment dimension must be within the tolerance.
On the gear set in the example listed the deviation is + 0.15 mm from the basic dimension in the positive direction and corresponds to the dimension which is written on the end face of the drive pinion. A further 1.5 mm is to be added to this deviation due to the height of bevel gear head of 39 mm. The measured value is thus + 1.65 mm.
The adjustment dimension "A" is the basic design adjustment of the drive pinion, the basic deviation "a" must be within the permitted tolerance in the plus or minus direction. The basic deviation "a" is the dimension which is written on the end face of the drive pinion.
If the adjustment dimension is outside the tolerance, the shim (S) which was installed is to be reground or a new shim of suitable thickness is to be installed. However, it is absolutely essential that a new spacer sleeve is used for the tapered roller bearings.
