WINCH FRAME MOUNTING
Use (8) 1/2" diameter grade 5 or better bolts to attach mounting frame to the wrecker.
CABLE INSTALLATION
The RPH-25000 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-25000 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:
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.
