(15) Adjustment bolt (pinion)
(16) Bevel pinion shaft The differential is used to transfer power from the transmission output shaft to the final drives. The final drives then transfer power to the wheels. The differential allows the rear wheels to turn at different rates of speed. When the machine is turned, the differential allows the inside wheels to turn at a slower rate of speed than the outside wheels. The differential can be unlocked or locked by the operator. The differential lock control button (17) is located in the cab on the right joystick control.The output shaft of the transmission directly turns bevel pinion shaft (16). Bevel pinion shaft (16) turns bevel gear (9), which is fastened to differential case (gear) (13). The differential has spider shaft (8) for pinions (6). The differential has two side gears: left side gear (5) and right side gear (11). The connections between four pinions (6) and the two side gears are at right angles through a gear mesh. Left side gear (5) and right side gear (11) are connected to the shafts by splines which are connected to the final drives.When the machine is moving straight in a forward direction and the differential is in the UNLOCK position, the same amount of torque is applied to the wheels on each side. The same amount of torque that is sent to each shaft for the final drive stops pinion (6) so the pinions cannot turn on spider shaft (8). This gives the same effect as if both tandem drives are being driven by the same shaft. When the machine is turned, different forces are applied to the opposite sides of the differential. This action will turn pinions (6). The rotation of pinions (6) allow the inside wheels to rotate at a slower rate of speed than the outside wheels. This moves the machine through the turn under full power.

Location of dash panel differential lock indicator
The differential can be locked by pressing differential lock control button (17). This button is located on the right joystick control in the cab of the machine. Pressing differential lock control button (17) pressurizes oil behind the piston in the differential lock. Locking the clutch discs (3) together forces the shaft to each final drive to turn together at the same speed. Pressing differential lock control button (17) again releases the oil pressure behind the piston. The reduction in oil pressure releases the differential lock. This will allow the two output shafts to turn at different speeds.The housing for the differential runs on tapered roller bearings. Pinions (6) turn on manganese bronze bushings. Pinions (6), left side gear (5), and right side gear (11) turn against
