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.
1.
Begin the undercarriage assembly by removing the front bumper of the
vehicle. There are four 1/2"-13 x 1-3/4" acorn head bolts with 1/2"
washers, two nut plates and two bumper shim plates to remove.
Note: The bumper shim plate prohibits the proper mounting bolts from
being installed. Either discard the plate or increase the size of the holes
located on the front.
Note: If your vehicle is equipped with a Blocker Beam™, review the
Technical Service Bulletin on page 33.
2.
Attach each HANGER PLATE (2) to the truck frame rails using two
1/2"-13 x 1-1/4" bolts and washers. Secure all bolts using a 1/2"-13 top
lock nut.
Note: Loosely attach all nuts until all undercarriage plates are
positioned.
3.
Rest both ZEE BRACKETS on the truck frame rail and fasten two
1/2"-13 x 1-1/2" bolts with washers to the hanger plate. Loosely tighten
1/2"-13 top lock nuts to all bolts.
4.
Install one 9/16"-12 x 1-1/2" bolt with a 9/16" washer inside of the truck
frame bumper bracket to the side zee bracket ear. Loosely thread a
9/16"-12 top lock nut to each bolt.
5.
Mount the PUSH BEAM to the hanger plate using two 1/2"-13 x 1-1/2"
bolts and top lock nuts.
Note: The proper height for the push beam is
approximately 12-1/2" from the ground to the center of the beam.
6.
Remove the M12-1.75 x 35 (10.9 Gr.) rear spring shackle bolt with
tabbed nut on the outside of the frame rail. Position each HANGER
SUPPORT PLATE on the outside of the hanger plate and truck frame rail.
Note: If your vehicle does not have a Blocker Beam™ installed on it, you
will need to add three 1/2" washers between the plate and the truck
frame rail. The washers are not needed if your vehicle came with the
Blocker Beam™ installed.
Reattach an M12-1.75 x 60 (10.9 Gr.) bolt and
the original tabbed nut. Bolt the support plate into the truck frame rail
using two 1/2"-13 x 2" bolts. Secure the support plate to the hanger plate
and push beam using two 1/2"-13 x 2-1/4" bolts and lock nuts.
7.
Once all of the undercarriage plates have been positioned and the proper
push beam height is set, proceed to tighten all top lock nuts. Reference
the chart on page 4 for maximum bolt torque.
8.
Replace the bumper using the existing hardware.
9.
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 locking 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.
