Insert dial indicator (052a) with measuring pin into the measuring device (052).
Press adjusting piece (052b), part 10 from measuring device, against the measuring device (052) and position dial indicator (052a) on "0" under 2 mm preload. Tighten clamp screw, checking the "0" position of the dial indicator (052a) and re-align if necessary.
The measuring pin for the dial indicator (052a) is screwed into the adjusting piece (052b)

The adjustment dimension (A) is the design basic setting of the drive pinion, the deviation in basic setting (a) having to be within the permissible tolerance in the positive or negative direction. The deviation in basic setting (a) is the dimension which is to be read off on the end face of the drive pinion.

If the adjustment dimension is outside the tolerance, the installed shim should be reground or a new shim of the appropriate thickness should be installed and a new spacer sleeve should be used for the tapered roller bearings in order to guaranteed satisfactory operation.
