REAR BUMPER ASS’Y w/ EXTENSIONS
(52H11 with 52H13 Extensions)
INSTALLATION INSTRUCTIONS
1.
Review all directions and diagrams provided before starting bumper installation.
2. Trim truck frame to indicated dimensions (See Fig. 1). 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 this measurement and the dimensions in Fig.
1, the vertical channel [P/N: 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. 2). Once the length has been determined for the
vertical channels, weld them to the truck frame (See additional notes on next page).
4.
Center the bumper weldment [P/N: 52H12] with factory installed extensions [ P/N: 52H13]
on the vertical channels [P/N: 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. 1 & 2).
