(1) Differential case. (2) Disc pack. (3) Pressure plate. (4) Bevel gear. (5) Side gear. (6) Pinion gear. (7) Shaft. (8) Thrust washer. (9) Side gear.The limited slip differential is identical on the left side and the right side of the shaft (7). The limited slip differential contains the following components: bevel gear (4), four pinion gears (6), right side gear (9), two clutch packs (2), two pressure plates (3), differential case (1), shaft (7) and left side gear (5). The right axle shaft is splined to the right side gear (9). The left axle shaft is splined to the left side gear (5).

Components of the Clutch Packs (1) Differential case. (5) Side gear. (6) Pinion gear. (10) Clutch discs. (11) Clutch plates. (12) Pressure disc. The clutch pack contains the following components: four clutch discs (10), five clutch plates (11) and pressure disc (12). The clutch discs (10) are splined to the side gears (5) and (9). The clutch plates (11) are splined to the differential case (1).

No Slipping ConditionThe limited slip differential operates identically to a standard differential during straight forward operation or during straight reverse operation. The limited slip differential provides 50 percent torque to each wheel.When the machine is in a turn, the inside wheel has more resistance than the outside wheel. The resistance in the inside wheel overcomes the clutch pack. The clutch pack slips and the limited slip differential turns the outside wheel identically to a standard differential.

Maximum Slipping ConditionWhen one wheel has more traction than the other wheel, the limited slip differential sends the torque to the wheel with the most traction. The clutch packs allow the differential to send the power to the wheel with the most traction. A standard differential could only transfer the same amount of torque from the slipping side to the opposite side.
