DESCRIPTION
CAUTION:
The
differential
is
serviced
as
an
assembly only do not attempt to disassemble.
Failure to follow these instruction will result in
damage to the differential.
The Trac-Rite™ differential is a helical gear differen-
tial. The differential has two side gears (3), two thrust
washers (1) and one spacer (2).
It also has six pinion brake shoes (1) which pivot on
the six pinion gear (2) shafts (3).

OPERATION
CAUTION:
The
differential
is
serviced
as
an
assembly only do not attempt to disassemble.
Failure to follow these instruction will result in
damage to the differential.
When one wheel begins to spin the pinion gears (2)
on that side, are forced toward the pinion brake shoes
(1). The pinion brake shoes then cause frictional drag
on the opposite pinion gears and the side gear. These
friction forces transfer the power to the opposite
wheel. Once the frictional forces are overcome, differ-
entiation will occur. The torque will be continually
biased by the frictional forces to the high traction
wheel.
CLEANING
CAUTION: The differential is serviced as an assembly only do not attempt to disassemble. Failure to follow
these instruction will result in damage to the differential.
Flush the differential case and gears through openings in the case with light oil.
DIFFERENTIAL-ELECTRIC LOCKER
DIAGNOSIS AND TESTING
1. Lift one rear wheel of the ground.
2. Turn key to the on position.
3. Place vehicle in drive/first gear and transfer case in LOW LOCK.
4. Activate locker switch.
5. Manually rotate the wheel that is off the ground. The wheel should lock once the dog clutch is aligned.
6. Turn off locker switch.
7. Manually rotate the wheel that is off the ground. The wheel should turn.
