INSTRUCTIONS
Due to the variations in type and model of trucks, dump bodies and PTO assemblies, no one set of instructions will be
applicable to all units. The following information is offered as a guide for laying out an individual unit. Considerable
latitude is permitted in mounting of parts. The mounting kits contain sufficient parts to allow mounting on most any
type of truck. Read the material in this manual carefully before attempting installation.
Recommended sequence of installation is as follows:
1. Mounting of pump and pump drive.
2. Installation of cab controls.
3. Mounting of spreader.
4. Installation of hydraulic hose and electrical wiring.
5. Filling hydraulic reservoir and lubrication.
6. Checking for leaks and functioning.
CAUTION
Be careful when drilling so as to not damage truck frame, gas tank, or any other important
components.
DO NOT WELD ON VEHICLE FRAME! Such welding can lead to fatigue cracking and must be avoided.
NOTICE!
DO NOT PUT HOLES INTO TOP OR BOTTOM FLANGES—to do so may void truck manufacturer’s
warranty. When drilling holes in frame member, drill only through vertical web portions.
NOTICE!
Connect welders ground directly to one of the items being welded anytime an arc welder is used on
the vehicle or anything connected to the vehicle. Refer to Manufacturer’s instructions.
IMPORTANT!
Disconnect electrical components from electrical system when welding on equipment to
prevent component damage due to power surges or excessive current.
INSTALLATION INSTRUCTIONS
HYDRAULIC RESERVOIR AND FILTER
(if HECO Supplied)
The hydraulic reservoir is mounted on the truck frame on either side. It should be as close to the truck cab as
practical and where filler neck is accessible with the suction line being as short as possible. Drill four 7/16” (1.1cm)
diameter holes through the frame channel vertical web for the mounting holes for the tank brackets and bolt the
reservoir into place.
The filter is installed on the tank using a pipe coupling and a close nipple. Use thread sealer as explained in the
Hydraulic Hose section under Installation Instructions. The oil must flow through the filter in the direction of the
arrow on the filter head casting. After installation, the element should be down and vertical.

CAB CONTROL VALVE
(If HECO Supplied)
When selecting a location for the cab control, there are a number of things to consider:
1. Select a suitable location for the operator to adjust the control and to turn it On and Off.
2. Check for clearance with the seat in all positions.
3. Check the transmission gear shift in all gears for clearance with the valve and the valve lever in the On and Off
positions.
4. If there are any other controls, such as parking brake, plow and wing controls, check for clearance.
5. Under the cab check for interference with transmission, etc.
6. Check to see that control valve location does not interfere with entering or leaving the cab.
I N S TA L L AT I O N I N S T R U C T I O N S
All holes in the truck cab walls, floor and firewall for control wires, hoses and cables are to
CAUTION be grommetted, plugged and sealed to prevent entrance of engine fumes, dust, dirt, water
and noise.
TAILGATE BAFFLES
Tailgate baffles are furnished to bolt or weld to the inside rear corner of the tailgate.
1. Gather parts needed to install tailgate baffles in truck dump body.
2. Close the tailgate and slide each baffle down until it clears the floor by 1/8” (.3cm). Clamp into position with
1/8” (.3cm) clearance between the baffle and the side of the dump body.
3. Swing the tailgate open approximately 8” (20.3cm) and check clearance between baffles and the floor. At an 8”
(20.3cm) gate opening, the leading edge of the baffle should almost touch the floor of the dump body.
4. Trim the top edge of the baffle to suit the dump body and bolt in place using hardware provided.

1. Locate the LH and RH mounting brackets on each
side of the dump box. Position the center of the
pivot 9 3/4” (10.9cm) below the dump box floor
and 1 1/4” (3.18cm) past the rear of the dump
box as shown in Figure 4. If the unit will use the
spinner attachment, the brackets may have to be
mounted further rearward. Drill mounting holes
in the dump box and bolt the brackets in place.
2. To locate the stabilizer bar measure down 17 1/2”
(44.45cm) from the dump box pivot point and
forward 2 1/8” (35.4cm) as shown in Figure 5.
Clamp the stabilizer bar to the truck frame when
one of the three pivot holes are at the measured
location. Mark and drill two 9/16” (1.43cm)
holes in the truck frame and attach using 1/2”
hardware. See Mounting parts list in operator’s
manual.
3. To determine the second hole location in the
leveling links, measure the distance between
the spreader pivot point and the dump body
pivot point. This is the “X” dimension shown in
Figure 5. Mark the leveling link the “X” dimension
plus 1/2” (1.27cm) from the center of the single
hole and drill 29/32” (2.3cm) diameter hole in all
four links. The extra 1/2” (1.27cm) is to allow for
settling of the spreader when it is attached. Cut
off the remaining material 1” (2.54cm) past the
center of the drilled hole.
4. Lift the spreader into place and pin in all three
pivot point locations being sure to use the pin
locking devices (cotter pin, pin catch) at each
location.
5. Carefully raise the dump body through its
complete range of movement. Make sure the
spreader stays level. If not, adjust the position of
the stabilizer bars until it does stay level.

HYDRAULIC HOSE
Determine the pressure port of the pump (Figure 12). Install the
pressure hose into this port. Connect the suction hose to the
opposite port and to the tank outlet on the reservoir. If necessary,
use plastic tie straps to support hoses so they will not catch on field
obstructions, or contact muffler or moving parts.
Use thread sealer on all fittings, except O-ring and JIC adapter,
O-ring valves and motors, etc. When using thread sealer, do not
put in on the first three threads of the fitting. Too much on the
fitting or on the first three threads will force it into the oil stream
where it could damage the system.
Figure 12 - Hydraulic Pump
Assemble the system as shown in the Hydraulic System section underGeneral Operating Procedures in the operator’s
manual. Place the hose clamps as needed to keep hoses away from hot or moving parts. Do not let hoses hang so
low as to be snagged. Do not stretch hoses tight.
The Hydraulic Hoses supplied are as follows:
Pressure Line - Two wire braid hose, one end fitting crimped on, the other end fitting to be field installed after
cutting hose to length. See assembly instructions on the following page.
Suction Line - Single spiral wire reinforced to be cut to length. Fittings to be assembled with double hose clamp.
All Return Lines - Double cotton braid to be cut to length as necessary. Fittings to be assembled with single hose
clamps.

HYDRAULIC HOSE MAINTENANCE
WARNING
To prevent serious personal injury testing should be conducted in approved test stands with
adequate guards to protect the operator.
Hose assemblies in operation should be inspected frequently for leakage, kinking, abrasion, corrosion or any other
signs of wear or damage. Worn or damaged hose assemblies should be replaced immediately.
I N S TA L L AT I O N I N S T R U C T I O N S
Clean
Clean assembly by blowing out with clean compressed air. Assemblies may be rinsed
out with mineral spirits if the tube stock is compatible with oil, otherwise hot water at
150°F (65.55° C) maximum may be used.
Inspect
Examine hose assembly internally for cut or bulged tube, obstructions, and cleanliness.
For segment style fittings, be sure that the hose butts up against the nipple shoulder;
band and retaining ring are properly set and tight, and segments are properly spaced.
Check for proper gap between nut and socket or hex and socket. Nuts should swivel
freely. Check the layline of the hose to be sure the assembly is not twisted. Cap the
ends of the hose with plastic covers to keep clean.
Test
The hose assembly should be hydrostatically tested at twice the recommended working
pressure of the hose.
Test pressure should be held for not more than one minute and not less than 30
seconds. When test pressure is reached, visually inspect hose assembly for: 1. Any
leaks or signs of weakness. 2. Any movement of the hose fitting in relation to the hose.
Any of these defects are cause for rejection.
STORAGE AND HANDLING
Hose should be stored in a dark, dry atmosphere away from electrical equipment, and the temperature should not
exceed 90° F (32°C).

control access, does not contact any moving parts or sharp edges and is kept away from any hydraulic lines or
heated parts. All lights and reflectors which are blocked by the spreader must be moved to meet all applicable local,
regional or national codes.
CONTROL PANEL (TGC-18 ONLY)
The control panel is equipped with a conveyor indicator light. The purpose of the indicator light is to be aware
when the conveyor is running. The control panel must be mounted in the cab such that the indicator light is clearly
visible. The pressure switch that activates the indicator light must be plumbed into the conveyor hydraulic circuit.
(See Hydraulic System parts list in operator’s manual, item 52) Wire as shown in figure 5. (See Control Panel parts
list in operator’s manual.)
NOTICE!
The conveyor must be moving (Indicator light on) whenever the dump box is being raised. Failure to
do so will result in the shearing of the leveling link shear pin and possible damage to the conveyor
hopper.

MIRROR INSTALLATION (TGC-18 ONLY)
The mirror is used to monitor the material flow into the conveyor. It can be mounted to the left or the right side of
the spreader. Bolt the mirror mount to the spreader through the existing hole in the lip of the spreader, and attach
mirror (Figure 6). Rotate the mounting weldment and /or adjust mirror so that from the driver’s seat the conveyor
is visible. Drill a 9/32” (.71cm) diameter hole for the lower mounting hole and secure with the enclosed hardware.
