ATTACHING VALVE ASSEMBLY TO WINCH MOTOR. (SEE FIGURE 1)
Rotate winch onto its front so that smooth machined area on the winch motor is facing up.
Remove rubber plugs from holes in the side of the winch motor. Remove the 2 Motor square-cut 0-rings from
rubber plugs and re-seat at the lips of the holes from which they were removed in the motor.
Remove rubber bands from valve assembly being sure not to drop metal washers (B) and flow disk (C).
The purpose of the flow disk is to maintain back pressure for controlled release of cable under tension. If this
disk is installed improperly it will negatively affect the performance of your winch and greatly reduce its pulling
power. This is a safety item; IT MUST BE INSTALLED.
BEFORE SECURING VALVE ASSEMBLY TO THE MOTOR MAKE SURE THAT THE FLOW RESTRICTOR DISK IS IN PORT
LABELED #1 WITH THE FLAT SIDE FACING THE SOLENOID BODY AND THE CUT SIDE FACING THE WINCH MOTOR. Also,
make sure that the hole(s) in the valve assembly have thin O-ring(s) installed, then re-seat the metal washer(s).
*A small dab of axle grease can be used to help hold the metal washers in place.
Use the four allen bolts supplied (f-5/16 18 X 1 ½ SS Socket Head Cap Screw) to mount the solenoid valve to the
winch motor. Make sure to Lock-Tite the allen bolts using no washers. Tighten to 25 ft/lbs.
*Note: Lock-Tite not included.
