Description
General
This section has the description and repair procedures for the differential, speed reducer, drive axle, wheel
bearings, and mounts for the axle housing.
Description
The drive axle assembly is fastened to the frame of
the lift truck by separate mounts. See Figure 1. The
drive axle assembly can rotate in the mounts. The
outer ends of the axle housings are the spindles for
the wheel bearings. The wheel bearings are tapered
roller bearings with the cups pressed into the hubs.
The nut on the end of the axle housing adjusts and
holds the wheel bearings. The axle shafts are fas-
tened to the hubs by capscrews and two dowel pins.
The back plate and brake assembly are fastened to
the axle mounts. The axle housing also has bearing
journals for the upright.
The outer wheel bearing is lubricated by gear oil from
the differential housing. The inner wheel bearing is
lubricated by wheel bearing grease.
