D. All Rockwell-Standard bronze bushed differential pinions should be ball burnished after bushing installation.
Install the bushing with a small stepped drift. The small O.D. should be .010" smaller than the bushing
burnished I.D. and 1 1/2 times bushing length. Always install bushings so end is even with the I.D. chamfer or
about 1/16" below the spherical surface.
E. When assembling component parts use a press where possible.
F. Tighten all the nuts to the specified torque. (See torque limits following service instructions). Where a lock-wire
is employed, use soft iron locking wire to prevent possibility of wire breakage.
G. The burrs, caused by lock washers, at the spot face of stud holes of cages and covers should be removed to
assure easy reassembly of these parts.
REASSEMBLY. (Table 4-2 ).
1.

Splined Shaft.
A. If new cups are to be installed, press firmly against pinion bearing cage shoulders.
B. Lubricate bearings and cups with light machine oil.
C. Press rear thrust and radial bearings firmly against
the pinion shoulders with a suitable sleeve that will bear
only on bearing inner race.
D. Install radial bearing lock ring and squeeze ring into pinion shaft groove with pliers.
