INSTALLATION INSTRUCTIONS – REAR BUMBER ASSEMBLY w/ EXTENSIONS
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 bottom of the truck frame to the ground (NOTE: This should
be performed on a level surface). Based on this measurement and the dimensions in Fig.
A, 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 truck frame (see additional
notes on the next page).
4. Center the bumper weldment
[Pt. No. 52H12] with factory
installed extensions [Pt. No. 52H13] 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).
