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 at least one tie plate must be attached to the
mounting feet at the bottom of the winch to maintain alignment. NOTE:
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, at
Angle Mounting Kit, #251006, 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 14 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) 1/2-13NC x 1-1/2 Lg. Gr. 5 capscrews with
lockwashers will be needed to mount winch. Capscrews should be torqued to 85 ft. lb. (115 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.
*CAUTION:
If longer bolts (minimum Grade 5) are substituted to mount winch or to mount a roller
guide at the side mount pads, bolt length must be such as to allow a maximum of .56 inch thread
length engagement in the tapped holes in sides of each end bearing. Refer to page 13. Use of
excessive length bolts will not allow tie plate to tighten down properly. Torque bolts to 55 ft. lbs. (75
Nm).

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. 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 #21) 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.

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.
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 the 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 13)
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 freespooled 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.
AIR CYLINDER CLUTCH SHIFTER (Refer to page 14)
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: 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 engagement indicator light (green light) is lit. DO NOT attempt to
pull a load unless the green light is lit. To connect light to the vehicle electrical system refer to the
Electrical Schematic on page 14.
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.
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 7. Add additional lubricant, Mobilith SHC 007, to gears if required.
