3 To determine the size of the shim washer to be
interposed between the pinion and the bearing,
position two opposed flanges, as shown in the fig-
ure. Tighten bolt (5) so that bearings can turn
freely.
4 Position the bearing supports on the differential
unit and tighten the bolts two by two.
5 Measure diameter (d) of the bearing seats.
6 Position pin (7) between the bearing seats and
measure size (Y) with a gauge.
- BE CAREFUL NOT TO TIGHTEN EXCESSIVELY.
