DIFFERENTIAL TRAC-RITE
DESCRIPTION
The Trac-RiteŸ differential is a helical gear differ-
ential. The differential has two side gears, six pinion
gears and six pinion brake shoes.
NOTE: The differential is seviced as an assembly
only if damaged, but can be disassembled for
cleaning. The assembly should be cleaned every
time a bearing is changed due to damage.
OPERATION
When one wheel begins to spin the pinion gears on
that side are forced toward the pinion brake shoes.
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.
DISASSEMBLY
(1) Remove differential ring gear bolts.
(2) Remove differential case cover locating screws
(Fig. 38).
(3) Remove differential case cover.(4) Remove side gear and thrust washer (Fig. 39).
NOTE: Mark all component locations.
(5) Remove three pinion brake shoes (Fig. 40).

CLEANING
Clean the differential case and gears with light oil
or a lint free cloth.
NOTE: Never use water, steam, kerosene or gaso-
line for cleaning.
INSPECTION
NOTE: Minor corrosion, nicks or scratches can be
smoothed with 400 grit emery cloth and polished
out with crocus cloth.
(1) Inspect pinion gears teeth for chips and cracks
(Fig. 42).
(2) Inspect pinion gears shafts and brake shoes for
scratches, flat-spots or worn (Fig. 42).(3) Inspect side gears teeth for chips and cracks
(Fig. 43).
(4) Inspect pinion and side gear bores for scratches
(Fig. 44).
NOTE: If any damage is found the differential must
be replaced as an assembly. Individual components
can not be replaced separately.
