CHAPTER 12

REPAIR OF M916/M920 REAR TANDEM AXLE

Section 1. FORWARD REAR AXLE

12-1. Description.

The forward rear drive unit of the tandem axles is a front-mounted, single-reduction,

through-drive type employing a two-gear transfer train.

The unit incorporates hypoid reduction gears and

bevel type gears in the main differential assembly and interaxle differential assembly, which is located

behind the helical drive gear on the input shaft (figs. 12-1 and 12-2). Lubrication is accomplished by

oil pump feed, splash, and spray. The unit has a no-spin positive locking differential identical to the one in

the M915. (See para 11-2 for description.)
