Rear Axle - 10 1/2AA
DIFFERENTIAL-TRAC-RITEDESCRIPTION
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(tm) differential is a helical gear differential. 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, differentiation will occur. The torque will be continually biased by the frictional forces to the high traction wheel.
