SAFETY I STRUCTIO S
• Read all installation, safety and maintenance instructions completely before
operating this equipment
• Keep all personnel clear of moving parts while equipment is being operated.
• Do not operate equipment in need of maintenance! Repair immediately!
• While operating this equipment, use common sense, use caution, be alert
and be safety-conscious.
AVOID HIGH-PRESSURE FLUIDS
Escaping fluid under pressure can penetrate the skin causing serious injury.
Avoid the hazard by relieving pressure before disconnecting
hydraulic or other lines. Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands and body from
high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid injected into
the skin must be surgically removed within a few hours or gangrene
may result.

Packing List:
Check the materials received against the order and packing list to verify that
all components have been received. Some hydraulic components may be
shipped direct from the manufacturer.
Position Spreader Trough:
The trough is to be mounted solidly on the rear of the dump body
directly below the tailgate hardware, as close to the body as
possible.
Set the tailgate in the horizontal position by pivoting it in the lower hinges and supporting it
with the chains. Mark a line across the rear of the body at the lower surface of the tailgate.
Raise the tailgate.
Place the spreader trough against the body just under the tailgate with the auger drive on
the right side. It should be 1” below the line and against the body. The trough should be
parallel to the dump body floor and centered from side to side. Verify that the trough cover
and dump body tailgate may be opened and closed without interference.
Attaching Trough to Dump Body:
The trough is attached to the dump body rub rails by using the quick-detach hardware as
shown in figure #2.
Sealer Strip:
If irregularities in the rear of the body cause openings between the body and the trough lip,
you may want to add a 7 gauge sealer strip welded or bolted to the lip to close these gaps.
Tailgate Shields:
Bolt or weld the shields to the inside of the tailgate to prevent material spillage at the ends.
See figure #1.

QUICK-DETACH HARDWARE I STALLATIO
Quick Detach Hardware Installation
1. Position spreader in desired position against rear of dump body.
2. Center body Q-D bracket on body rub rail and flush with end of body.
3. Weld or drill holes and bolt bracket to body.
4. Bolt the hanger bar to the spreader end plate. Do not tighten bolt.
5. Assembly the hanger pin bracket to the hanger bar and lock in place with hair pin keeper.
6. Moving the hanger bar, locate a good place near the top of the body for the hanger pin
bracket. Weld it to the body. Tighten bolt.

FOR CHIPPI G ATTACHME T
Chipping Attachment Assembly:
1. Bolt the mounting bracket weldment to the front plate of the roll spreader, flush with the
front plate.
2. Mount the chipping attachment to the trough by bolting the attachment bar to the bracket
weldment.
Stabilizer Bar:
The object of the stabilizer bar is to create a parallelogram linkage between the dump body
hinge pin, stabilizer bar, and the chipping attachment. This ensures that the chipping attachment
will maintain a 50˚ angle to the road surface at any dump angle. (Reference Figure 1)
1. (Reference Figure 2) Position the stabilizer bar on the chassis so that the hole is 8.5” directly
below the dump body hinge pin. Weld the stabilizer bar in place.
2. (Reference Figure 2) Install one of each of the stabilizer rods in the stabilzier bar and the stabi-
lizer weldment on the chipping attachment. old the chipper attachment at the 50˚ angle to the
ground and weld the rods together. Insert the lynch pins through the stabilzer rods.

HYDRAULIC SYSTEM - I STALLATIO I STRUCTIO S
Mounting instructions for:
Thru-shaft hydraulic pump, reservoir, filter, valve and hoses (all standard truck and hydraulic
spreader plumbing installations).
General:
The Thru-shaft pump, valve, reservoir & filter, with mounting brackets and fasteners, may be
used on most any truck with an existing transmission PTO and continuously operating
dump hoist pump installation.
CAUTION: If dump body is rais d for asi r ump installation, it must b block d s cur ly
b for disconn cting hoist pump.
Important:
1. Taking time to plan location of major hydraulic components will save time in further plumb-
ing operations.
2. All pipe fittings should be cleaned before installing and all other hydraulic components to be
kept as clean as possible during assembly.
3. Check rotation of PTO for proper pump mounting.
4. Pump must be mounted so shaft rotates in direction of arrow.
5. Two (2) U-Joints (one standard type and one slip type) must be used on ends of each piece
of shafting installed in drive train.
6. Yokes on U-Joints must be in phase (lined up) for smooth operation. CAUTION! A set
screws in U-Joints must be tight and proper y safety wired.

PUMP I STALLATIO
1. Check PTO RPM with truck engine at 2000 RPM. This reading should be in the operating
range of 1,200 to 1,500 RPM. If this range cannot be achieved, it will be necessary to
change the PTO accordingly.
2. Pump is installed between transmission PTO and existing hoist pump. Remove existing
shaft connecting PTO to hoist pump.
3. Determine best location for pump and mount on bracket,
(following general instructions below):
a. Keep in mind location of suction hoses, pressure hoses, and valve.
b. Pump drive shafting should be in as straight a line as possible, not to exceed 15-
degree bend at any U-joint.
c. Pump drive shafting may be cut to length as needed.
d. If hoist pump is swivel type, that moves as dump body is raised or lowered,
distance should be allowed between new pump and hoist pump for workable
slip U-joint.
e. Short leg of pump bracket is bolted inside truck chassis frame.
f. Pump is bolted to long leg of bracket, using holes which best align pump.
g. Mounting bracket may be re-bent as needed and any excess cut off.
h. Furnished brace may be welded as needed for added support on pump bracket.
NOTE: Moving of hoist pump may be required; follow above general instructions as needed for
re-installation of hoist pump.

1. ydraulic components should be
kept as clean as possible during
assembly operations.
2. Galvanized pipe and pipe fittings
must not be used because flaking of
galvanizing material can cause
damage to major hydraulic
components.
3. A pipe joint sealant compatible with
hydraulic oil must be applied to all
NPT fittings. (Teflon tape is not
recommended.)
4. Sufficient hose should be allowed
for raising dump body without
kinking or stretching hose.
5. ose should be protected where
severe wear may be caused by
vibration or sliding movement.
6. Long runs of hose should be
supported by tie wiring or clamping.
7. Pressure and return hoses,
connected to spinner or auger
motors, may be reversed for proper
motor rotation.
8. Three hose lines to rear of truck
may be installed inside truck frame,
under dump body floor, and secured
in place.
9. Use hose manufacturer's
recommendations for fitting reusable
hose ends.
10. To eliminate hose twisting, allow
hose end clamp to remain loose
until hose end fitting is screwed
tightly in place.
