RAMSEY HYDRAULIC PLANETARY WINCH MODEL RPH 12,000 PLEASE READ THIS MANUAL CAREFULLY This manual contains useful ideas for obtaining the most efficient operation from your Ramsey Winch, and safety procedures one needs to know before operating a Ramsey Winch. Do not operate this winch until you have carefully read and understand the "WARNING" and "OPERATION" sections of this manual. WARRANTY INFORMATION Ramsey Winches are designed and built to exacting specifications.
WINCH MOUNTING ESSENTIAL MOUNTING INSTRUCTIONS TO MAINTAIN ALIGNMENT OF PLANETARY WINCH COMPONENTS It is most important that this winch be mounted securely so that the three major sections (the motor end, the cable drum and the gear-housing end) are properly aligned. Excessive bushing wear and difficulty in freespooling are usually symptoms of misalignment.
CABLE INSTALLATION 1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of cable, opposite hook, with plastic or similar tape to prevent fraying. 2. Place taped end of cable into hole in cable drum, as shown below. Use 3/8-16NC x 1/2 lg. Hx. Soc. drive setscrew (part of 234171 drum assembly) to secure cable to drum. 3. Carefully run winch in the "reel-in" direction.
HYDRAULIC SYSTEM REQUIREMENTS Refer to the performance charts below to properly match your hydraulic system to the winch performance. The charts consist of: (1) first layer line pull (LB) vs. working pressure (PSI), (2) first layer line speed (FPM) vs. flow (GPM), and (3) relief valve setting (PSI) vs. flow (GPM). A motor spool directional control valve is required. SYSTEM REQUIREMENTS: 2500 PSI RELIEF VALVE SETTING* 15 GPM FLOW RATE** 10 MICRON NOMINAL FILTRATION *CAUTION: DO NOT EXCEED 20 G.P.M.
OPERATION The best way to get acquainted with how your winch operates is to make test runs before you actually use it. Plan your test in advance. Remember, you hear your winch, as well as see it operate. Get to recognize the sounds of a light steady pull, a heavy pull, and sounds caused by load jerking or shifting. Avoid conditions where load shifts or jerks occur, as they may indicate a dangerous situation.
TROUBLE SHOOTING GUIDE CONDITIONS POSSIBLE CAUSE CORRECTION / ACTION DRUM WILL NOT ROTATE AT NO LOAD Brake damaged. Inspect and replace brake. Gears damaged. Inspect and replace damaged gears. Brake not releasing See section below. Load greater than rated capacity of winch. Refer to Specifications pg.1 for line pull rating. Low hydraulic system pressure. Check pressure. Refer to HYDRAULIC SYSTEMS performance charts pg. 4. Low hydraulic system flow rate. Check flow rate.
INSTRUCTIONS FOR OVERHAUL OF RAMSEY WINCH MODEL RPH 12,000 DISASSEMBLY Take note of mounting configuration for proper mounting of parts during re-assembly. Disconnect tube (item #44) from elbows (item #24) on bottom of brake (item #6) and valve (item #45). Remove motor (item #31) from brake housing (item #6) by unscrewing capscrews (item #15). Tap motor lightly to disengage. Replace all gaskets, o-rings and seals with new ones during re-assembly. Remove coupling (item #23) from brake housing.
Remove brake housing (item #6) from end bearing (item #4) by unscrewing (6) capscrews (item #14) in a criss-cross pattern (2 turns each) until all capscrews are removed from brake housing. Remove brake parts from brake housing. Examine brake discs (item #26) for signs of wear, and replace if necessary. Examine o-rings (items #34 & #35) and backup rings (items #36 & #37) for signs of wear. Remove o-rings and backup rings from grooves in brake piston (item #3).
Remove tie plates (item #9) from end bearings (items #4 & #5) by unscrewing capscrews (item #16), as shown. Remove snap ring (item #41) and thrust washer (item #48) from shaft. Slide motor end bearing (item #4) from drum (item #1) and drum from gear housing end bearing (item #5). Remove input shaft (item #8) and thrust washer (item #47) from end bearing. Inspect gear teeth and splined end of shaft for signs of wear. If damaged, it will be necessary to replace shaft.
Generously apply grease (MOBILITH SHC 007) to teeth of ring gear (item #28), teeth of planet gears in drum (item #1) and to bushing in gear housing end bearing (item #5). Apply a small amount of grease to base of bushing on motor end bearing (item #4). Apply grease to teeth of gear and short end of shaft (item #8). Place gear end of shaft through thrust washer (item #47) and into bearing in end bearing (item #5).
Set winch on gear housing end with motor end bearing (item #4) up. Insert (6) springs (item #42) into pockets of motor end bearing (item #4), as shown, leaving top and bottom pockets empty. Install coupling (item #23) over splined end of shaft (item #8). Put (4) brake pins (item #7) into (4) holes in motor end bearing. Install well-oiled oring (items #34 & #35) and backup rings (items #36 & #37) into grooves in O.D. of piston (item #3).
Place gasket (item #28) into position on mounting surface of motor (item #31). Slide motor shaft into coupling and attach motor to brake housing (item #6). Use (2) capscrews (item #15) with lockwashers (item #22) and torque to 87 ft. lbs. (118 Nm) each. Securely connect tube (item #44) to elbows (item #24) in valve (item #45) and in bottom of brake housing (item #6). Apply at least 550 PSI hydraulic system pressure to release brake and verify that brake releases, by observing that the winch drum rotates.
