1.
Begin the installation by removing the PLASTIC AIRFOIL mounted to the
bottom of the front bumper.
Note: The airfoil will need to be permanently
removed or notched to accommodate the undercarriage assembly.
2.
Remove and discard the three bolts that secure each tow hook to the
truck frame. The tow hooks should remain in the same position.
3.
Align the UNDERCARRIAGE MOUNTING POCKETS (at each end of the
PUSH BEAM) with the tow hook mounting brackets on the vehicle.
Note:
Use a hydraulic floor jack to help facilitate the installation procedure.
4.
Install two M12 x 1.75 x 45 (8.8 Gr.) bolts with M12 washers to the SIDE
TOW HOOK MOUNT for each end of the assembly.
Note: Loosely attach
all nuts until the remaining hardware is in position.
5.
Proceed to install one M12 x 1.75 x 40 (8.8 Gr.) bolt with an M12 washer
through the TRUCK FRAME and REAR TOW HOOK MOUNT for each
side of the push beam. Both bolts will tighten into the existing tow hook.
6.
Install the the two 5/8"-11 x 2-1/4" bolts and 5/8" washers through the
REAR SUPPORT ARMS and TRUCK FRAME CROSSMEMBER. Secure
each bolt with a 5/8"-11 top lock nut.
7.
Once the undercarriage is positioned with the appropriate hardware,
tighten all top lock nuts. Reference the chart on page 4 for maximum
bolt torque.
8.
Position the LIGHT TOWER into the accepting pockets on the push beam
and tighten using two 1/2"-13 x 1-1/4" bolts with washers. Secure each
bolt with a 1/2" top lock nut. Mount each PLOW HEADLIGHT to the light
tower with the hardware kit provided.
Complete the assembly by plugging the connectors from the lights into the
connectors on the vehicle wire harness.
12-1/2"
WARNING: Most new trucks are
equipped with driver and passenger’s
side air bags. DO NOT remove, disable, or
reposition any sensory equipment related to
the safe operation of the air bags.
ALWAYS follow the vehicle manufacturer’s
recommendations for installing snowplowing
equipment.
Failure to comply with the above warning may
result in serious injury or death.
CAUTION: If your vehicle is equipped
with oversize tires, they may come
into contact with the undercarriage hanger
plates when turning the vehicle.
The problem may be resolved by setting the
steering stops on the vehicle. If this does not
correct the problem, the original tires will need
to be installed on the vehicle.
The recommended push beam height for all
undercarriage assemblies is 12-1/2" from the
center of the push beam to level ground. DO NOT
exceed 14" in height for any undercarriage.
