WINCH MOUNTING
Use (8) 3/4" diameter grade 5 or better bolts to attach winch to the wrecker.
Before operating the winch for the first time, remove the cover from the breather vent at the back of the air
cylinder and the relief fitting on top of the clutch housing.
CABLE INSTALLATION
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. Insert the end of cable, opposite hook end, into the hole in drum barrel. Secure cable to drum barrel, using
setscrew furnished with winch. TIGHTEN SETSCREW SECURELY.
3. Carefully run the winch in the “reel-in” direction, winding one full wrap of cable on the drum.
4. Apply air to the cable tensioner. Wind about 5 wraps of cable onto the drum and stop. Using a hammer tap
these five wraps of cable over again the cable anchor flange side of the drum.
5. Finish spooling all the cable onto the cable drum, taking care to form neatly wrapped layers.
HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts to properly match your hydraulic system to RPH-50000 winch performance.
The charts consist of:
(1) Line pull (lb.) first layer vs. working pressure (PSI) and (2) Line speed (FPM), first layer vs. flow (GPM).
Performance based on a motor displacement of 9.6 cubic inches with 25 GPM maximum flow rate. See
page 16 for motor port size.
