CABLE INSTALLATION
An “A” or “B” decal on the clutch end bearing indicates the spooling direction of the cable. Also, a letter “A” or “B” is
stamped in the end bearing on the clutch end indicating rotation direction. If the decal is damaged or unreadable,
contact Customer Service for additional instructions to determine proper direction. To reverse the rotation direc-
tion, exchange positions of the cartridge and plug shown below.
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. Insert the end of the cable through roller fairlead.
3. Place taped end of cable under tensioner plate and into hole in cable drum. Use the 3/8-16NC x 1/2” long hex
socket drive setscrew (included with drum assembly) to secure cable to drum.
4. Carefully run winch in the "reel-in" direction. Wind about 5 wraps of cable onto the drum and stop. Using a ham-
mer tap these five wraps tightly over against the cable anchor flange of the drum. 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 #20) and turn nylon setscrew (item #17) 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 oper-
ate. 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 dan-
gerous situation.
The uneven spooling of cable, while pulling the load, is not a problem, unless there is a cable
pileup on one end of the 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, and 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 dimensional drawing page 12):
TO DISENGAGE CLUTCH: Run the winch in the reverse (reel out) direction until the load is off
the cable. Pull handle out and rotate 90°. With handle in the DISENGAGED” position, cable may
now be free-spooled from the drum. TO ENGAGE CLUTCH: Pull handle out, rotate 90° and re-
lease 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 the dimensional drawing 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:
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 engage-
ment indicator light (green light) is lit. To install 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 bro-
ken strands, replace immediately. Cable and hook assembly (100’ long cable) P/N 524118
may be purchased from a Ramsey distributor.
2. Check that the clutch is fully engaging. See OPERATION instructions, above, for the appro-
priate clutch shifter. FOR MANUAL CLUTCH ONLY: Monthly, disengage clutch, put several
drops of oil on the clutch handle shaft and work clutch handle IN and OUT several times to
lubricate inside the shifter assembly.
3. Check to see that the drum cable does not overrun (“birdnest”) when freespooling. Refer to
page 2 if it does.
4. Replace drum bushings and seals if seals begin to seep grease. Refer to the Overhaul In-
structions, pages 6-11. Add additional lubricant, Mobilith SHC 007, to gears and drum bear-
ings if required.

input shaft (item #13).
Place end of shaft with output sun gear on it into drum (item #1). Rotate shaft to engage planet gears with
output sun gear. Place Gear End Bearing on Drum and engage planet gears with ring gear.
Assemble motor end bearing (item #11) to drum assembly and use mounting angle (item #2) and capscrews
(items #19) loosely to hold both end bearings together. Assemble mounting angle (item #3) and partial ten-
sioner assembly together with capscrews (item #65). CAUTION: Mounting angle capscrews are different
lengths! Ensure the correct capscrews are installed. Tighten capscrews to 55 ft-lbs (75 Nm). If neces-
sary, remove and replace the shifter assembly (manual, item #5, or air-cylinder, item #6), as follows:
MANUAL CLUTCH SHIFTER ASSEMBLY
Loosen setscrew (item #23) and jam nut, then unscrew shifter assembly (item #5). Be sure slot in ring gear
is not aligned with clutch shifter hole. Rotate drum, if necessary, to ensure hole and slot are not aligned.
Reinstall shifter assembly with plunger, jam nut, and handle positioned in gear housing as shown below.
Thread assembly (with handle engaged in cylinder slot) into the gear housing. Pull drum toward the gear
end bearing housing to remove play. Hold drum in position and continue threading the shifter assembly in
until the gap between the end of the handle and cylinder is 7/16 +0/ -1/16 inch and handle is in the horizontal
position (see below). Note: This gap will vary with drum endplay. With the drum pulled against the motor end
housing, the gap should be 3/8 inch.
Lightly tighten jam nut. Rotate drum until handle snaps fully into the engaged position. Pull handle out and
rotate 90°. Verify that drum can be rotated freely (at least one full revolution) with clutch shifter at the DIS-
ENGAGED position. Securely tighten jam nut while holding the handle. Tighten setscrew (item #23) se-
curely. Re-check clutch operation as described on page 4.

posite sides.
Install roll pin (item #42) into new motor coupling below bottom of spline teeth. Insert motor cou-
pling (item #29), engaging it with the discs and the input shaft.
Place gasket (item #31) on mounting surface of motor (item #34). Slide motor shaft into coupling. Attach
motor to motor end bearing housing using (2) capscrews (item #22) and (2) lockwashers (item #28).
Evenly tighten to 49 ft-lbs. (66 Nm) torque.
Install the counterbalance valve (item #50) to the motor using (4) capscrews (item #16) and (4) lock-
washers (item #26). Tighten to 17 ft-lbs (23 Nm).
Securely connect fittings (item #30) to motor end housing and counterbalance valve, and connect tube
assembly (item #49) to fittings.
Apply at least 550 PSI hydraulic system pressure to brake and verify that brake releases (winch drum
will rotate).
Insert capscrews (item #55) through top plate and slotted
tensioner plate. Install springs (item #60), washers (item
#28), and secure with nylon lock nuts (item #66) to desired
cable tension. Springs require a small amount of compres-
sion before capscrews engage nylon lock nut threads. If it is
difficult to compress springs to engage capscrews with nylon
lock nut, loosen tensioner mounting bolts (item #65). Tighten
capscrews to 55 in-lb (75 Nm). Recommended spring com-
pression is 0.75” per spring. See figure at right.
Insert the end of the cable into the opening of the roller fair-
lead so that it passes under the tensioner plate and install
cable into the cable anchor.
Watch the tensioner as the cable is spooled onto the drum.
The tensioner must be free to move without obstruction to
function properly. If tensioner touches any surrounding
structure, correct the problem.

RAMSEY WINCH warrants each new RAMSEY Winch to be free from defects in material and
workmanship for a period of one (1) year from date of purchase.
The obligation under this warranty, statutory or otherwise, is limited to the replacement or re-
pair at the Manufacturer's factory, or at a point designated by the Manufacturer, of such part
that shall appear to the Manufacturer, upon inspection of such part, to have been defective in
material or workmanship.
This warranty does not obligate RAMSEY WINCH to bear the cost of labor or transportation
charges in connection with the replacement or repair of defective parts, nor shall it apply to a
product upon which repair or alterations have been made, unless authorized by Manufacturer, or
for equipment misused, neglected or which has not been installed correctly.
RAMSEY WINCH shall in no event be liable for special or consequential damages.
RAMSEY WINCH makes no warranty in respect to accessories such as being subject to the
warranties of their respective manufacturers.

prove its products through changes in design or materials as it may deem desirable without be-
ing obligated to incorporate such changes in products of prior manufacture.

tive. Bills for service, labor or other expenses that have been incurred by the Buyer without ap-
proval or authorization by RAMSEY WINCH will not be accepted
