Transfer Case: Description and Operation

Transfer Case Description and Operation





The Honda AWD transfer case (1) is mated to the rear side of the 5-speed automatic transmission assembly beside the differential. The transfer case assembly consists of an aluminum case and side cover and drive and driven gears. The gear set is a hypoid design. Both the drive and driven gear shafts are supported by tapered roller bearings. Pinion depth, gears backlash, and bearing preloads are adjusted during production using 25, 40, and 80 mm shims of various thickness. The internal components of the transfer case are lubricated by hypoid gear oil.





The transmission (1) differential drive gear rotates the transfer output sub-shaft (2). The transfer output sub-shaft is splined to and drives the transfer case input gear (3). The transfer case output shaft (4) transfers power through the output flange to the Variable Torque Management rear differential (6) via a 2-piece propeller shaft assembly (5).
