Section view of transfer and bevel gears (1) Pinion (2) Transfer gear (3) Transfer gear (4) Transmission input shaft (5) Transmission output shaft (6) Bevel gear (7) Shaft (bevel gear)The transfer and bevel gears are located in the transfer case. The transfer case is attached to the transmission case. The transfer and bevel gears transfer mechanical power from the transmission through the brakes to the final drive.A drive shaft connects the yoke on the torque converter to the yoke on the transfer case. The yoke on the transfer case is connected to transmission input shaft (4) by splines.When a speed clutch and a direction clutch are engaged, power is sent from the planetary transmission to transmission output shaft (5). Then, the power is sent to transfer gear (3) .Transfer gear (3) turns transfer gear (2). Transfer gear (2) is connected to pinion (1) by splines. Pinion (1) turns bevel gear (6) .Bevel gear (6) is fastened to bevel gear shaft (7) by bolts. The inner axle shafts send power to the brakes.The bevel gear, the pinion, and the transfer gears are lubricated with oil from the power train oil system. Oil flows through passages in the transfer case and through a tube in the bevel gear case. Oil from the tube lubricates the gears by spray lubrication.
