WINCH MOUNTING
ESSENTIAL MOUNTING INSTUCTIONS TO MAINTAIN ALIGNMENT OF PLANETARY WINCH COMPONENTS
It is 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 free spooling are usually
symptoms of misalignment.
In the as-installed condition, if the winch is mid mounted at least one tie plate must be attached to the mounting feet
at the bottom of the winch to maintain alignment. NOTE: If the winch is foot mounted at least one tie plate must
remain mounted at mid point of winch to maintain alignment. It is always desirable to use both tie plates in the final
install configuration.
Angle Mounting Kit, #251173, is recommended for maximum ease in mounting the winch. The angle kit will allow
the winch to be mounted in upright or mid mount applications and will meet the criteria of serving as solid and true
mounting surface.
When mounting the winch with other than recommended Ramsey Angle Kit, the mounting hole patterns described on
pages 14-15 must be used. The mounting surface must be flat within .015 inch and sufficiently stiff to resist flexing. If
a steel plate is used for foot mounting it should be .750 inch thick. For this mounting application eight (8) 5/8-11NC
x 1-1/2 Lg. Gr. 5 capscrews with lock washers will be needed to mount winch. Capscrews should be torque to 173 ft.
lb. (235 Nm)
NOTE: If angles or a steel plate are used in mounting winch, tie plates provided with winch are to be attached to the
remaining mounting pads, whether they be side or foot.

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 234173 drum assembly) to secure cable to drum.
3. Carefully run winch in “reel-in” direction. Keep tension on end of cable, spool all the cable onto the cable drum,
taking care to form neatly wrapped layers.
After installing cable, check free spool operation. Disengage clutch and pull cable at a walking speed. If cable “bird
nests”, loosen jam nut (item #22) and turn nylon screw (item #19) clockwise to increase drag on drum. If cable pull
is excessive loosen nylon setscrew by turning counterclockwise. Tighten jam nut when proper setting is obtained.
CAUTION: Over-tightening of jam nut may strip nylon setscrew.

HYDRAULIC SYSTEM REQUIREMNTS
Refer to the performance charts below to properly match your hydraulic system to the winch performance. The charts
consist of: (1) line pull (LB) first layer vs. working pressure (PSI); line speed, first layer (FPM) vs. flow (GPM). A
motor spool directional control valve is recommended.
SYSTEM REQUIREMENTS
2300 PSI RELIEF VALVE SETTING
15 GPM FLOW RATE*
10 MICRON NORMAL FILTRATION
Caution: Do not exceed 30 gpm. If exceeded, motor and winch may be damaged.
The best way to get acquainted with how your winch operates is to make tests 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.
The uneven spooling of cable, while pulling a load, is not a problem, unless there is cable pileup on one end of drum.
If this happens, reverse the drum 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.
When pulling a heavy load place a blanket, jacket or tarpaulin over the cable about five or six feet behind the hook. In
the event of a broken cable. This will slow the snap back of the cable and could prevent serious injury.
The winch clutch allows rapid unspooling of the cable from the cable drum for hooking onto the load. The clutch is
operated by clutch shifter lever or air shifter.
WARNING: DO NOT DISENGAGE CLUTCH UNDER LOAD
MANUAL CLUTCH SHIFTER (Refer to page 9)
TO DISENGAGE CLUTCH: Run the winch in reverse (reel out) direction until load is off the cable. Pull handle out and
rotate 90˚. With handle in the “DISENGAGED” position, cable may now be free-spooled from drum.
TO ENGAGE CLUTCH: Pull handle out, rotate 90˚ and release handle. Run the winch in reverse until the clutch handle
snaps fully into the “ENGAGED” position. DO NOT attempt to pull a load unless the handle is fully at the “ENGAGED”
position. If manual shifter indicator light is present, the green light is lit when clutch is fully “ENGAGED”. DO NOT
attempt to pull a load unless the green light is lit.
AIR CYLINDER CLUTCH SHIFTER (Refer to page 9)
TO DISENGAGE CLUTCH: Run the winch in reverse (reel out) direction until load is off the cable. Apply air pressure to
the .125-27NPT port: 80 PSI (min.), 150 PSI (max.) CAUTION: pressure must not exceed 150 PSI.
TO ENGAGE CLUTCH: Remove air pressure from the cylinder (a return spring engages the plunger). Run winch in
reverse until the clutch is fully engaged. DO NOT attempt to pull a load unless clutch is fully engaged. If shifter indicator light is present, the green light is lit when clutch is fully engaged. DO NOT attempt to pull a load unless the
green light is lit.
MAINTAINANCE
1. Inspect the cable for damage and lubricate frequently. If the cable becomes frayed with broken strands, replace
immediately.
2. Check that the clutch is fully engaging. See OPERATION instructions, above, for the appropriate clutch shifter.
FOR MANUAL CLUTCH ONLY: Monthly disengage clutch, put several drops of oil on the shaft and work clutch IN
and OUT several times to lubricate inside of clutch cylinder.
3. Check to see that drum cable does not overrun (bird nest) when free spooling. Refer to page 3.
4. Replace drum bushings and seals if seals begin to seep grease. Refer to OVERHAUL INSTRUCTIONS, page 8.
Add additional lubricant, Mobilith SCH 007, to gears if required.
