General
This section has the description and repair procedures for the differential, speed reducer, drive axle, and the
mounts for the axle housing.
Description
The drive unit assembly is fastened to the frame of
the lift truck by the axle mounts. See Figure 1 and
Figure 2. The outer ends of the axle housings are
the spindles for the wheel bearings. The cups for the
wheel bearings are pressed into the wheel hubs. The
nut on the end of the spindle holds and adjusts the
preload on the wheel bearings. The axle shafts are
fastened to the hubs by capscrews. Studs and nuts
fasten the wheel to the hub and brake drum. The
back plate and brake assemblies are fastened to the
axle mounts.

the pinion to the reduction gear. The reduction gear
is engaged with the drive gear on the differential.
