quited to rotate one side gear while
the other is held stationary. The
initial breakaway torque may exceed
250 lb. ft. The rotating torque re-
quired to keep the side gear turning
with new clutch plates is 100 to 250
lb.
ft. With re-used clutch plates, the
minimum torque required is
40 lb. ft.
(The torque may fluctuate 10-40
lb. ft.).
REMOVAL AND
DISASSEMBLY OF
DRIVE PINION AND
BEARING RETAINER
1. Turn the carrier case upright,
and remove the pinion shaft nut
(Fig. 24). Then remove the U-joint
flange (Fig. 25).
2. Remove the seal
(Fig.
53) and
the slinger.
3. Remove the pinion, bearing,
and retainer assembly from the car-
rier housing. Measure the shim
thickness with a micrometer. Record
this original shim thickness. If a new
gear set is installed during assembly,
a new shim will have to be installed.
The original shim thickness is one of
the factors necessary in determining
the new shim thickness.
Extreme
care must be taken not to damage
the mounting surfaces of the
retainer and carrier.
