WINCH FRAME MOUNTING

Use (8) 1/2" diameter grade 5 or better bolts to attach mounting frame to the wrecker.

CABLE INSTALLATION

The RPH-20000 winch has two tapered pockets cast into the drum. One pocket is for installations
with the wire rope wound over the drum. The other pocket is for an underwound wire rope. When
properly used, the wedge pocket design is one of the most secure anchoring methods available.

1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of wire
rope, opposite hook, with plastic or similar tape to prevent fraying.

2. Slide the wire rope through narrow end of pocket against the drum flange and wrap the wire rope
around the anchor “puck” and pull the wire rope and anchor back into the wide end of the pocket.
Use a soft hammer to drive the back side of the wire rope, firmly seating the wire rope and anchor,
into the pocket.

3. Carefully run the winch in the “reel-in” direction. Keeping tension on end of cable, spool all the
cable onto the cable drum, taking care to form neatly wrapped layers.

The wire rope can easily be removed from the drum by driving the anchor out the wide end of the
pocket.

HYDRAULIC SYSTEM REQUIREMENTS

Refer to the performance charts, below, to properly match your hydraulic system to RPH-20000 winch

performance. The charts consist of:

(1) Line pull (lb.) first layer vs. working pressure (PSI) and (2) Line speed, first layer (FPM) vs. gallons per

minute (GPM). Performance based on a motor displacement of 8.0 cubic inches with 15 GPM maximum
flow rate. See page 13 for motor port size.

PERFORMANCE CHARTS

CLUTCH OPERATION

To engage clutch:

BASED ON 8.0 CU. IN/REV. MOTOR

1. Move the clutch control valve to the “clutch engaged” position.

2. Anytime the temperature is below freezing, run the motor in the “cable out” direction only until the
drum starts to turn. In extreme cold temperatures (below 0o F/-18o C), pull out on the cable by

hand only until the drum starts to turn.

3. Wait at least 3 seconds for the clutch to fully engage, after which the winch is ready to winch in
the cable.

WARNING: Do not attempt to engage the clutch by first running the winch motor and then moving
the clutch control valve to the "clutch-engaged" position while the motor is running. Do not start
picking up the load at the same time the clutch is being engaged.

To disengage clutch:

Run the winch in the "cable out" direction until the load is off the cable.

1.

2. Move the clutch control valve to the "clutch-disengaged" position.

The cable may now be pulled off by hand.

WINCH OPERATION

The best way to get acquainted with how your winch operates is to make test runs before you use
it. Plan your test in advance. Remember, you hear your winch, as well as see it operate; learn to
recognize the sounds of a light steady pull, a heavy pull, and sounds caused by load jerking or
shifting. Gain confidence in operating your winch and its use will become second nature with you.

The uneven spooling of cable, while pulling a load, is not a problem, unless there is a cable pileup
on one end of drum. If this happens reverse the winch to relieve the load and move your anchor
point further to the center of the vehicle. After the job is done you can unspool and rewind for a
neat lay of the cable.

MAINTENANCE

Adhering to the following maintenance schedule will keep your winch in top condition and performing
as it should with a minimum of repair.

A. WEEKLY

Check the oil level and maintain it to the oil level plug. If oil is leaking out, determine location and

1.

repair.

2. Check the pressure relief plug in top of the gear housing. Be sure that it is not plugged. Lubricate

cable with light oil.

B. MONTHLY

1. Check the winch mounting bolts. If any are missing, replace them and securely tighten any that are

loose. Use grade 5 or better bolts.

2. Inspect the cable. If the cable has become frayed with broken strands, replace immediately.

C. ANNUALLY

1. Drain the oil from the winch annually or more often if winch is used frequently.

2. Fill the winch to the oil level plug with clean kerosene. Run the winch a few seconds with no load in the

reel in direction. Drain the kerosene from the winch.

3. Refill the winch to the oil level plug with all purpose SAE 80W-140 gear oil.

4. Inspect frame and surrounding structure for cracks or deformation.
