CHAPTER 10

REPAIR OF M916/M920 FRONT AXLE

10-1. Description

a.

The axle has steering ends bolted to the outer ends of the axle housing. A cardan joint in the

axle shaft located within the axle ball and socket permits the shaft to rotate and drive the wheel while

allowing it to steer the vehicle (fig. 10-1 and 10-2).

b.

The drive unit for the front axle is a single reduction unit that employs a heavy-duty spiral

bevel or hypoid pinion and gear. The differential and gear assembly is mounted on tapered roller

bearings. The straddle mounted pinion has two tapered roller bearings in front of the pinion teeth which

take the forward and reverse thrust and a third bearing behind the pinion teeth to carry the radial load.
