DIFFERENTIAL BEARING PRELOAD
Requires special tool No. SK-119-FGC
Assemble the differential case (57) and end cap (58),
and bolt the crownwheel (56) to it. Fit the differential
unit into the maincase (1) using dummy bearings SK-
119-FGC, and fit the sideplate (3). Adjust the shims
(103) if necessary, to achieve 4 – 6 lbs.ft of bearing
preload torque (to turn the diff assembly in it’s bearings
when oiled.).
The table below is to inform you of which sideplate
spacers should be used with which crownwheel when
mounted on a TPT differential. The reason that there are
two sets of spacers, is that the crownwheels have
different mounting distances.
