WARNINGS:
CLUTCH MUST BE TOTALLY ENGAGED BEFORE STARTING THE WINCHING
OPERATION.
DO NOT START WINCH MOTOR BEFORE ENGAGING CLUTCH
DO NOT DISENGAGE CLUTCH UNDER LOAD.
STAY OUT FROM UNDER AND AWAY FROM RAISED LOADS.
STAND CLEAR OF CABLE WHILE PULLING. DO NOT TRY TO GUIDE CABLE.
DO NOT EXCEED MAXIMUM LINE PULL RATINGS SHOWN IN TABLE.
DO NOT USE WINCH TO LIFT, SUPPORT, OR OTHERWISE TRANSPORT
PEOPLE.
A MINIMUM OF 5 WRAPS OF CABLE AROUND THE DRUM BARREL IS
NECESSARY TO HOLD THE LOAD. CABLE ANCHOR IS NOT DESIGNED TO
HOLD LOAD.

HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts, below, to properly match your hydraulic sys-
tem to RPH 50000 winch performance. The charts consist of :
(1) Line pull (lb.) first layer vs. working pressure (PSI) and
(2) Line speed, first layer (FPM) vs. Flow (GPM). Performance based on a
motor displacement of 9.6 cubic inches with 25 GPM maximum flow
rate.

CAUTION: SYSTEM BACK PRESSURE MUST NO EXCEED 50 PSI OR

BRAKE SHAFT FAILURE CAN OCCUR. IF BACK PRESSURE EXCEEDS
50 PSI, AND CANNOT BE REDUCED, AN EXTERNAL CASE DRAIN
SHOULD BE RUN FROM THE MOTOR CASE DRAIN PORT (SEE
PAGES 20-21) TO TANK OR A LINE/CONNECTION THAT HAS A
PRESSURE BELOW 50 PSI. THE DRAIN LINE MUST BE ROUTED SO

AIR SYSTEM REQUIREMENTS

The cable tensioner requires an independent, adjustable regulated air supply of
between 50 and 90 PSI.
CAUTION: DO NOT EXCEED 100 PSI AIR PRESSURE TO THE AC-
TUATORS. THIS COULD CAUSE DAMAGE TO THE ACTUATORS.
The clutch release cylinder requires an air supply of between 100 and 120 PSI.

WINCH FRAME MOUNTING

Use (8) 5/8 inch diameter grade 5 or better bolts to attach mounting frame to
wrecker.
Before operating winch for the first time, remove the cover from the breather
vent at the back of the air cylinder and the relief fitting on top of the clutch
housing.

4
CLUTCH OPERATION
To engage clutch:
1. Move the clutch control valve to the "clutch-engaged" position.
2. Anytime the temperature is below freezing, run motor in the "cable out"
direction only until the drum starts to turn. In extreme cold temperatures
(below 0° F/ -18° C), pull out on the cable by hand only until the drum
starts to turn.
3. Wait at least 3 seconds for the clutch to fully engage, after which the
winch is ready to winch in the cable.
WARNING: Do not attempt to engage the clutch by first run-
ning the winch motor and then moving the clutch control
valve to the "clutch engaged" position while the motor is run-
ning. Do not start picking up the load at the same time the
clutch is being engaged.
To disengage clutch:
1. Run the winch in the "cable out" direction until the load is off the cable.
2. Move the clutch control valve to the "clutch-disengaged" position.
3. The cable may now be pulled off by hand

2 SPEED CONTROL OPERATION

Your winch is equipped with a 2-speed hydraulic motor. It is controlled by the
application of 12 vDC to the Motor Control Valve solenoid. Do not change
motor speed while winch is in operation. Loss of load control and/or
damage to your winch could result.
CABLE TENSIONER OPERATION
If you remove the cable entirely from the winch or this is a new instal-
lation:
The cable tensioner is not intended to be energized on a bare drum. Before
applying air to the cable tensioner, install the cable.
To adjust the free spool effort of the cable tensioner: Disengage the
winch clutch and free spool some cable off the drum. Adjust the air pressure to
the cable tensioner to achieve the desired free spool effort that also prevents
“bird-nesting” of the cable.
CAUTION: DO NOT EXCEED 100 PSI AIR PRESSURE TO THE AC-
TUATORS. THIS COULD CAUSE DAMAGE TO THE ACTUATORS.

5
CABLE INSTALLATION
1. Unwind cable by rolling it out along the ground to prevent kinking. Se-
curely wrap end of wire rope, opposite hook, with plastic or similar tape to
prevent fraying.
2. Insert the end of the cable opposite the hook end into the hole in the drum
barrel. Secure cable to drum barrel using setscrew furnished with winch.
TIGHTEN SETSCREW SECURELY.
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.
4. Apply air to the cable tensioner. Wind about 5 wraps of cable onto the
drum and stop. Using a hammer tap these five wraps of cable over
against the cable anchor flange side of the cable drum.
5. Finish spooling all the cable onto the cable drum, taking care to form
neatly wrapped layers.

The wire rope can easily be removed from the drum by loosening the setscrew.

WINCH 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. Gain
confidence in operating your winch and its use will become second nature with
you.
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.

6
MAINTENANCE
Adhering to the following maintenance schedule will keep your winch in top
condition and performing as it should with a minimum of repair.
A. WEEKLY
1. Check the oil level and maintain it to the oil level plug. If oil is leaking out,
determine location and repair.
2. Check the pressure relief plug in top of the gear housing. Be sure that it is
not plugged.
3. Lubricate cable with light oil.
B. MONTHLY
1. Check the winch mounting bolts. If any are missing, replace them and
securely tighten any that are loose. Use grade 5 or better bolts.
2. Inspect the cable. If the cable has become frayed with broken strands,
replace immediately.
C. ANNUALLY
1. Drain the oil from the winch annually or more often if winch is used fre-
quently.
2. Fill the winch to the oil level plug with clean kerosene. Run the winch a
few seconds with no load in the reel in direction. Drain the kerosene from
the winch.
3. Refill the winch to the oil level plug with all purpose SAE 80W-140 gear
oil.
4. Inspect tiebars and surrounding structure for cracks or deformation.

Cable Tensioner Overhaul
Note: Your winch will come in either
an overwound or underwound version.
The disassembly and reassembly is
the same for either, but the appear-
ance and mounting of the cable ten-
sioner will be different (see figures at
right and below). If you are not certain
which version the winch you are work-
ing on is, refer to pages 19 and 20.

1. Disconnect the air supply from

the cable tensioner at the “T”
fitting (item #12).

2. Remove nuts (item #8) from

actuators (item #14) that hold UNDERWOUND
the actuators to the tensioner
plate (item #1). Remove pin
(item #3) by removing cotter pin
(item #11) and washer (item
#10) on both sides.

3. Remove the tensioner plate and

inspect the actuators for damage.

4. Remove and replace any dam-

aged parts. Tighten capscrews
(item #6) that attach tensioner
bar to tensioner plate to 20-25 ft-
lbs. torque.

OVERWOUND

18
5. Insert the pin (item #3) through the bracket (item
#5) and secure with the washer (item #10) and
cotter pin (item #11). Replace nuts (item #8) and
tighten to 8-10 ft-lbs. torque.
6. Center the tensioner bar between the drum
flanges. Loosen (do not remove) the mounting
bolts (item #7) and center with a scale or tape
measure. Tighten the mounting bolts to 60-70 ft-
lbs. torque.
7. Reconnect the air supply to the “T” fitting (item
#12) on the cable tensioner. Do not tighten more
than 1/4 turn beyond hand tight. If the cable was
removed, do not energize the cable tensioner until
the cable is installed. See the instructions on
page 6.
