Installation Instructions
Mounting the Spreader onto the
Vehicle
1. Install the inverted “V” in the
spreader using the 3/8 - 16X 1” hex
bolts, 3/8” nuts, and 3/8” washers
provided.
2. Remove the tailgate from the
vehicle.
3. Lift the spreader by attaching the
lifting device to the slot on the
passenger side of the rear inside
brace.
4. Place the spreader on top of two
pieces of lumber so that the lumber
rests under the side gussets as
shown in figure 7. NOTE: This will
help to remove any excess material
that accumulates under the
spreader.
5. Place the spreader in the back of the
vehicle so that it is centered to the
vehicle and the rails of the spreader
are 14” from the rear of the truck.
6. Bolt the spreader to the vehicle
frame through side gussets and the
lumber.
7. Tie the spreader to the vehicle from
the tie-down eyes to the vehicles
anchor points.

Things to Know after Mounting the
Spreader
A. The tie-down straps are provided for
the purpose of securing the
spreader to the vehicle only and are
not to be used for any other
purpose. It is imperative that the
spreader be tied to the vehicle at all
times.
B. Be sure to verify with vehicles
manufacturer that the factory
installed anchor points are designed
for this application.
C. Periodically check to see if the
spreader mounting hardware is
securely tightened.
Mounting the Spinner/Chute
Assembly
1. Attach the Spinner/Chute Assembly
to the spreader inserting the lock
pins, shown in Figure 8, into the two
holes located at the end of the rails
of the spreader as shown in Figure 9.
2. Install the roller chain between the
sprocket mounted to the
Spinner/Chute Assembly and the
Motor Sprocket. Make sure both
sprockets are in-line with one
another. Tighten the gearbox
sprocket set screw. Install the roller
chain master link. See Figure 10.
Figure 8.
Figure 9.
Figure 10.

3. Adjust the tension of the roller chain
by loosening the Pillow Block
Bearings that are supporting the
Spinner Shaft. Move the shaft either
towards or away from the Motor
Sprocket to adjust the tension. The
correct chain tension should allow a
5/16” deflection in the chain
midway between both chain
sprockets. See Figures 11-12.
NOTE: Be sure to maintain the
vertical alignment between the
Spinner Shaft and the bearings
before re-tightening the hardware.
4. Install the chain guard using the
three ¼-20 X ¾” hex head bolts, lock
washers, and nuts.
5. Torque the 3/8-16 x 1-1/4” Pillow
Block Bolts to 236 Inch-Pounds (20
Foot-Pounds).
NOTE: At this point the spreader control
unit is ready to be installed. For
installation and operation instructions,
please refer to the “Electric Spreader
Control Manual” that has been provided.
Figure 11.
Figure 12.
CAUTION
Do not over-tighten the chain
tension. This can cause damage to
the chain, shaft, bearings and the
Motor.

Spreader Maintenance
1. Use dielectric grease on all electrical
connections before an electrical
connection is made or after a
connector is disconnected.
2. Grease the following:
a. Idler Shaft Bushings (2)
b. Drive Shaft Bushings (2)
c. Spinner Shaft Bushings (2)
d. Flanged Bearing located
between gearbox and clutch
e. Gearbox Input Shaft Bearing.
NOTE: Do not over grease. Can
cause seal damage.
3. Check the alignment of the
sprockets periodically.
4. Inspect the bearings in the motor
and the pillow blocks for proper
lubrication periodically.
5. Maintain the correct tension on the
following chains using the following
information:
a. Drag Chain Tension-Check to
make sure that the distance
between the end of the rail and
the point of contact between the
chain and the lower flange of the
rail is 26” to 30”. See Figure 13.
Turn the screws shown in
Figures 14 and 15 to adjust the
chain tension as needed.
Figure 13.
Figure 14.
Figure 15.

b. Motor to Conveyor Shaft Drive
Chains-Adjust the chain tension for
the sprocket assembly which
transmits power to the conveyor
shaft by loosening the pillow block
bearing bolts and sliding the shaft
and bearings in the desired
direction. Then torque the 3/8-16
Pillow Block Bolts back to 236 Inch-
Pounds (20 Foot-Pounds) when
finished. See Figure 16. NOTE: Be
sure to maintain the horizontal
alignment of the shafts to the
chains. Failure to do so could result
in damage to the sprockets, motor,
shafts, and chains.
Figure 16.
c. Motor to Spinner Shaft Drive
Chain-Correct tension for the
Drive Chain is also a 5/16”
deflection at the mid-point
between the two sprockets.
Adjust the chain by loosening
the Pillow Block Bolts as was
shown in Figures 11 and 12 and
slide the pillow blocks in the
desired direction.
6. Empty the spreader of all snow
control material when not in use to
prevent a frozen feed chain.
7. Wash out the spreader when it is
not in use and at the end of the
season to remove all snow control
materials. Thoroughly dry all metal
surfaces. Paint and oil all bare
carbon steel surfaces to help protect
against rust build-up. Properly store
spreader during the off-seasons.
