The case is fastened to the machine frame and is located near the center of the machine. Flange (1) is connected to the output drive shaft of the transmission. The flange is also splined to input shaft (2) of the transfer gears.Gear (3) is also connected to input shaft (2) by splines. Gear (3) is in mesh with gear (4), which is splined to shaft (6). Gear (5) is also splined to shaft (6). Therefore, gear (4) and gear (5) rotate at the same speed. Gear (5) is mesh with gear (7), which is splined to output shaft (8). Flanges (9) and (10) are connected to output shaft (8). Flanges (9) and (10) are also connected to the front and rear differential drive shafts.Power flows from the transmission output shaft, through the drive shaft and flange (1), to input shaft (2). Power then flows through gear (3), gear (4), shaft (6), gear (5), gear (7), through output shaft (8), flanges (9) and (10) to the drive shafts for the front and rear differentials.Differential And Drive Axle

When one wheel is turned slower than the other, the differential lets the inside wheel stop or turn slower in relation to the outside wheel.The output shaft of the transmission turns the drive shafts through the transfer gearbox. Power is sent through flange (1) and pinion (2). Pinion (2) turns ring gear (3) which is fastened to differential case (4). The power flows through pin (5), pinion gears (9), side gears (6) and finally to axle shafts (7) and (8).Differential case (4) contains four pinion gears (9), two side gears (6) and pin (5). The connection between pinion gears (9) and side gears (6) is at right angles through a gear mesh. Splines make the connection between side gears (6) and axle shafts (7) and (8).When the machine moves straight forward, traction under each wheel is the same, so the torque from each axle shaft is the same. Pinion gears (9) do not turn on pin (5). This gives the same effect as if both wheels are on the same axle shaft. When the torque that is sent to the axle shafts is not the same, as in a turn, torques that are not the same are put on opposite sides of the differential. This action makes pinion gears (9) turn on pin (5). The rotation of pinion gears (9) stops or slows the inside wheel and makes the outside wheel go faster. This moves the machine through a turn under full power.The differential gets lubrication from oil thrown about inside the housing.Differential
