Output Transfer Gears
(1) Case. (2) Drive gear. (3) Shims. (4) Idler gear. (5) Gear. (6) Shaft. (7) Yoke assembly. (8) Yoke assembly. (9) Oil reservoir.
The output transfer gears are at the output side of the transmission. The transmission output shaft is connected to drive gear (2) by splines.Drive gear (2) is engaged with idler gear (4). Idler gear (4) is engaged with driven gear (5). Driven gear (5) is connected to shaft (6) by splines. Yoke assemblies (7) and (8) are connected to shaft (6) by splines. Yoke assembly (7) is connected to the short drive shaft that goes to the rear differential. Yoke assembly (8) is connected to the drive shaft that goes to the bearing cage and to the front differential.The flow of power in the output transfer gears goes from the transmission output shaft to drive gear (2). The power then flows from drive gear (2) to idler gear (4). From idler gear (4), the power flows to driven gear (5). The power then flows from the driven gear to shaft (6).At shaft (6), the flow of power divides. Some of the power goes from yoke assembly (7) through a drive shaft to the rear differential. Some of the power goes from yoke assembly (8) through a drive shaft and through the bearing cage to the front differential.Shims (3) are used to adjust the end play of gear (2).Reference: Refer to the Service Manual module for Systems Operation, "Input Transfer Gear and Output Transfer Gear Lubrication" for the theory of operation for the lubrication of the input transfer gears.
