The hydraulic flow enters the speed control at the input
port (IN). Flow comes from the manifold valve block
(port PF).
The controlled flow going out of the speed control at the
controlled flow port (CF) goes to the spinner assembly
to power the spinner wheel hydraulic motors.
The hydraulic flow going out of the speed control at
the exhaust port (EX) is directed back to the manifold
valve block (port EX) and is used to power and control
the conveyor belt motor.
The spinner speed control does not have any user
serviceable parts. If the valve is malfunctioning, it will
need replacement.
LEFT AND RIGHT HAND SPINNER WHEEL
HYDRAULIC MOTORS
The spinner wheel hydraulic motors receive hydraulic
power from the manifold valve block solenoid valve
S1. Activation of the solenoid valve S1 is controlled at
the hand held ON/OFF switch. Hydraulic flow from the
block (port PF) is routed through the spinner speed
control. The controlled flow from the speed control
(port CF) is sent to the left hand motor port “A”. Flow
leaves the left hand motor through port “B” and enters
the right hand motor at port “B”. Flow out of the right
hand motor joins the case drain from the left hand
motor and returns to the manifold valve block at port
“SR”.
The direction of rotation is opposite from each other. The
right hand spinner wheel rotates counterclockwise, the
left hand spinner wheel rotates clockwise (as viewed
from above the WideSpin 1530 TM). The spinner
wheels are a direct drive from the hydraulic motors.
If the spinner or the spinner motors fail to operate,
check the following:
● Quick-disconnects not attached. Check one at port
“SR” on the manifold valve block and one on the
opposite end of the hose connected to port “CF” on
the spinner speed control valve.
● Spinner Speed Control set too low.
● Trucks throttle and/or governor set too low to provide
adequate engine RPM and hydraulic flow.
● Trucks hydraulic flow selector on wrong setting.
● Check for restricted operation with other
components. Check for a buildup of top dressing
material or obstructions caught under the spinner
wheels. Spinner wheels should not rub on the
directional shields.
● Check for loose hydraulic motors or out-of-position
hydraulic motors.
● Relief valve is bypassing all hydraulic power back
to the tank.
● Trucks Pump not operating.
● Damaged or non-functional motors.
● Mechanical problems with the motor and the spinner
wheel coupler. Check for sheared keys or damaged
coupling spider.
● Loose motor, check mounting screws and mounting
position.
Hydraulic flow leaving the spinner motors returns to
the manifold valve block, entering at port “SR”. Flow is
routed through the valve block is returned to the truck
through the “Pressure Out” hydraulic hose and quick
disconnect fitting.
PRESSURE OUT HYDRAULIC HOSE
The pressure out hose is part of the mounting kit. Refer
to the mounting kit manual for proper hose routing and
connection.
The quick disconnect on the pressure out hose must
be properly and completely connected to the truck. If
the quick disconnect is not properly connected to the
truck, excessive pressure can build up in the WideSpin
1530 TM resulting in a safety hazard and causing
serious damage to the top dressers hydraulic system.
TO AVOID SERIOUS BODILY INJURY and
To Avoid Serious Damage to the
WideSpin 1530 TM,
Both Hydraulic Hoses Must Be Properly and
Completely Connected To the Truck.
SECURELY CONNECT ALL
QUICK DISCONNECT FITTINGS!!
