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.
In the as-installed condition, if the winch is mid mounted then at least one tie plate must be attached to
the mounting feet at the bottom of the winch to maintain alignment. NOTE:
then 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 installed configuration.
If the winch is foot mounted
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 midmount applications and will meet the criteria of
serving as a solid and true mounting surface.
When mounting the winch with other than the recommended Ramsey Angle Kit, the mounting hole
patterns described on page 12 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 lockwashers will be
needed to mount winch. Capscrews should be torqued 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. Hex. Soc.
drive setscrew (part of 234173 to secure cable to drum.
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.
After installing cable, check freespool operation. Disengage clutch and pull on cable at a walking speed.
If cable "Birdnests", loosen jam nut (item #19) and turn nylon screw (item #15) 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.

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 that 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 a cable pileup on one end of
drum. If this happens, reverse the winch 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 cable drum, for hooking onto the load. The clutch is
operated by the clutch shifter lever or air shifter.
WARNING:
DO NOT DISENGAGE CLUTCH UNDER LOAD.
MANUAL CLUTCH SHIFTER (Refer to page 12)
TO DISENGAGE CLUTCH: Run the winch in the reverse (reel out) direction until load is off the cable. Pull handle
out and rotate 90o. With handle in the "DISENGAGED" position cable may now be free-spooled from drum.
TO ENGAGE CLUTCH: Pull handle out, rotate 90o 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 shift 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. To hookup light to the vehicle electrical system refer to
the Electrical Schematic on page 13.
AIR CYLINDER CLUTCH SHIFTER (Refer to page 13)
TO DISENGAGE CLUTCH: Run the winch in the reverse (reel out) direction until load is off the cable. Apply air
pressure to the .125-27 NPT port: 80 PSI (min.), 150 PSI (max.). CAUTION:
TO ENGAGE CLUTCH: Remove air pressure from the cylinder (a return spring engages the plunger). Run winch in
reverse until the clutch engagement indicator light (green light) is lit. DO NOT attempt to pull a load unless the
green light is lit. To hookup light to the vehicle electrical system refer to the Electrical Schematic on page 13.
MAINTENANCE
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
Pressure must not exceed 150 PSI.
3. Check to see that drum cable does not overrun (BIRDNEST) when freespooling. Refer to page 3.
4. Replace drum bushings and seals when seals begin to seep grease. Refer to OVERHAUL INSTRUCTIONS,
page 8. Add additional lubricant, Mobilith SHC 007, to gears if required.
