Mechanical Shift System

The Borg-Warner 13-56 manual shift transfer case (7A195) is a part-time three-piece transfer case. The case is magnesium, except for the F-350 with 137-inch wheelbase, chassis cab with E4OD transmission that has an aluminum front case half and an opening for a power takeoff (PTO). The unit is lubricated by a positive displacement oil pump that channels oil flow through drilled holes in the rear output shaft. The pump turns with the rear output shaft, and allows towing of the vehicle with transfer case in NEUTRAL position without disconnecting the rear driveshaft.

The input shaft (7017), front output shaft, 4WD indicator switch, and shift lever are located on the front case half. The rear output shaft, output shaft bearing retainer (or slip-yoke type bearing retainer), and drain and fill plugs are located on the rear case half. Two types of bearing retainers are used: a rear fixed output circular flange and a slip-yoke type.
