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).
