INSTALLATION INSTRUCTIONS – REAR BUMBER ASSEMBLY
1. Review all directions and diagrams provided before starting bumper installation.
2. Trim truck frame to indicated dimensions (see Fig. A). These dimensions will facilitate the
mounting of the rear light assembly if it is also being mounted.
3. Measure the distance from the top of the truck frame to the ground (NOTE: This should be
performed on a level surface). Based on this measurement and the dimensions in Figure
1, the vertical channel (Pt. No. 63H94) may need to be modified in length to meet the Office
of Motor Carrier Safety (OMCS) regulations. Regulation 393.86 requires that no bumper be
located more than 30" off the
ground when the truck is empty,
and the end of the bumper should
not be located more than 24" from
the extreme rear of the vehicle,
including truck bodies (see Fig. B).
Once the length has been
determined for the vertical
channels, weld them to the bottom
of the truck frame (see additional
notes on next page).
4. Center the bumper weldment (Pt.
No. 52H12) on the vertical channels
(Pt. No. 63H94). Position rear of
bumper from rear of the hoist as
indicated by the bumper location chart. This is
crucial in order to ensure that the container longsills do not contact the bumper during the
dump cycle (see Fig. A & B).
5. Weld the bumper weldment to
the vertical channels (see Fig. A
& C).
