WINCH FRAME MOUNTING
Use (8) 7/8 inch diameter grade 5 or better bolts to attach mounting frame to wrecker.
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 the cable opposite the hook end into the hole in the drum barrel. Secure cable to drum barrel
using setscrew furnished with winch. TIGHTEN SETSCREW SECURELY.
3. Carefully run 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 loosening the setscrew.
HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts, below, 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, first layer (FPM) vs. Flow (GPM).
Performance based on a motor displacement of 11.9/5.95 cubic inches with 13 GPM maximum flow rate. See page 13 for
motor port size.
