together for use later when main housing is
reassembled.
7. Before damaged shims are discarded, measure
and record total thickness of the pack. The
dimension will be needed to calculate depth of
drive pinion in main housing when gear set is
installed.

pinion shaft toward top assembly. Support
bearing cage under flange area with metal or
wood blocks. Press drive pinion through bearing
cage. Figure 2.37.
