pension mount casting as shown in Figure 2-3.
2. Raise rear axle housing of truck until tires clear
ground. Securely block up rear axle housing
near the wheel motor mounting flange.

from outer wheel valve stem vinyl clamp by
loosening capscrews. Lift valve extension out of
vinyl clamp.
4. Using a tire handler (or hoist and sling if body
has been removed as shown in Figure 2-4) to
grasp outer wheel assembly. Remove wheel
nuts (10, Figure 2-4) and wedges (11) securing
outer wheel to the wheel motor hub.

wheel before removing outer wheel assembly.
