BODY PADS

It is not necessary to remove the dump body to
replace body pads. Pads should be inspected during
scheduled maintenance inspections and replaced if
worn excessively.
1. Raise the body to a height sufficient to allow
access to all pads.
Place blocks between the body and frame.
Secure blocks in place. Never work under a
raised body unless safety device(s) are in posi-
tion to prevent dump body from lowering.
2. Remove hardware attaching pads to the dump
body. (Refer to Figure 3-4)
3. Remove body pad and shims. Note number of
shims installed at each pad location. (The rear
pad on each side should have one less shim
than the other pads)
4. Install new pads with the same number of shims
as removed in step 3.
5. Install the mounting hardware and tighten to 88
N·m (65 ft lbs) torque.
6. Remove blocks from frame and lower body onto
the frame.
