Trac-Lok Differential

DESCRIPTION
The Trac-Rite differential is a helical gear differential. The differential has two side gears, six pinion gears and six pinion brake shoes.

NOTE: The differential is serviced 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, differentiation will occur. The torque will be continually biased by the frictional forces to the high traction wheel.
