CHOKE ADJUSTMENT—GASOLINE ENGINE

CHOKE ADJUSTMENT
(HONDA ENGINES ONLY)

1. Engines are shipped with choke adjusted to the
completely closed position when the choke is
engaged. The choke only requires adjusting if
inspection reveals the choke is not fully closing.

2. Move the throttle control to full choke position.

3. Turn the choke adjusting screw counterclockwise

ve to seven turns.

4. Attempt to move the choke rod in the direction
of the choke adjusting screw. If the rod has no
movement, no adjustment is necessary.

5. Return the choke adjusting screw to its original
position or clockwise until it touches the choke
lever. If the choke rod has movement, bend
the engaging tab in the direction away from the
choke adjusting screw until there is no choke rod
movement.

6. In the event that bending the tab fails to remove
all choke rod movement, partially straighten out
the bend in the choke rod. This bend is near the
governor arm.

7. The choke adjusting screw, when properly
adjusted, stops excessive force from being
exerted on the choke actuator.

HYDRAULIC UNIT INSTALLATION

Port

Direction

Hydraulic Unit Installation

Recommended installation sequence:

1. Install the pump (not provided).

2. Install the hydraulic reservoir.

3. Install the cab control valve (optional).

4. Install the hydraulic hoses (not provided).

5. Fill the reservoir and check the system.

Pump

Because of the wide range of possible installations
for this hopper spreader, no pump is supplied with the
unit. If your vehicle does not have a pump suitable to
your application, one may be purchased from a local
truck equipment supplier.

The pump should produce 9 gal/min at 1500 psi at
normal operating speed and have 1" NPT suction and
discharge ports.

Hydraulic Reservoir Installation

Cab Control Valve Installation

1. With the seat fully forward, select a suitable
location to mount the cab control valve, allowing
for the operator to adjust the control and to turn it
ON and OFF.

2. Check for clearance with ALL controls in the cab.

3. Under the cab, check for interference with
transmission, etc.

4. Check to see that the cab control valve location

does not interfere with entering or leaving cab.

5. Fabricate a bracket to mount the cab control valve
in the selected location.

6. Insert a grommet into each hole drilled for this
installation.

7. Mount valve and plumb the pump and motor to
the valve. Plumb Port "Auger" to Port "B" of the
gearbox motor, and Port "Spinner" to Port "B" of
the spinner motor.

Position the reservoir outlet as high as, or higher than,

the pump inlet. Keep the hose distance as short as

possible.

The reservoir should have a capacity of 1‑1/2 to

2 times the pump maximum ow rate in gal/min.

8. Conrm proper rotation of drive shafts. Spinner
shaft should rotate clockwise. Check for hydraulic
uid leaks.

DRIVE CHAIN AND SPINNER CHAIN—
GAS MODELS

• Verify that the drive sprocket set screws and the
clutch sprocket mounting bolts are tight.

CAUTION

Overtightening the roller chains may damage
the bearings on the gear case and the engine.
Overtightening will also shorten the life of the
roller chain and of the sprockets.

• Correct tension allows for 1/4" of deection
midway between the pulleys/sprockets.

1/4"

CONVEYOR PINTLE CHAIN TENSION

Check the conveyor chain tension by conrming that

the chain is visible in the chain tension port. If the
chain is too tight, it will be above the port; if too loose,
it will be below the port.

To increase engine chain tension: Loosen the four
bolts that secure the engine mount to the engine
base and pull the engine away from the clutch.
After correct tension is achieved, retighten the
engine mount bolts.

Spinner drive chain tension is maintained by

the chain tensioner. Check the chain tensioner

pivot point and lubricate as required for smooth
tensioner movement. Full instructions on adjusting
spinner drive chain tension are in the "Mounting
the Spreader" section of these instructions. Under

"Chute Installation—Gas Models" see "Adjust
Spinner Drive Chain Tension."

 If Conveyor Chain Is Too Loose

1. Loosen the two bearing mounting bolts on each
side of the conveyor idle roller at the cab end of
the hopper.

2. Loosen the jam nut on one of the idler take‑up
bolts. Tighten the take‑up bolt by turning it
clockwise while holding the jam nut. Repeat with
the opposite take‑up bolt, tightening equally on
both passenger's side and driver's side until the
chain is in the middle of the chain tension port.

3. Tighten the bearing mounting bolts to 30 ft‑lb.
Tighten the tensioner jam nuts.

 If Conveyor Chain Is Too Tight

1. Loosen the jam nuts on both sides. Back off the
idler take‑up bolt evenly on both sides. Then
loosen the bearing mounting bolts.

2. Adjust the chain tension until the chain is visible in
the chain tension port.
