HYDRAULIC SYSTEM REQUIREMENTS

Refer to the performance charts to properly match your hydraulic system to HDP-50000 winch performance.

The charts consist of:

(1) Line pull (lb.) ﬁrst layer vs. working pressure (PSI) and (2) Line speed (FPM) ﬁrst layer vs. ﬂow (GPM).

Performance is based on a motor displacement of 11.9 cubic inches with 25 GPM maximum ﬂow rate. See

page 10 for motor port size.

HYDRAULIC SYSTEM REQUIREMENTS

WINCH OPERATION

The best way to get acquainted with how your winch operates is to make test runs before you use it.

Plan your test in advance. Remember, you hear your winch, as well as see it operate. Learn to recog-

nize 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.

CLUTCH OPERATION

To engage clutch:

1. Move the clutch control valve to the “clutch engaged” position.

2. Anytime the temperature is below freezing, run the 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 running the winch motor and

then moving the clutch control valve to the “clutch-engaged” position while the mo-

tor is running. 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.

CABLE INSTALLATION

1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of wire

rope, opposite hook, with plastic or similar tape to prevent fraying.

2. Insert the end of cable, opposite hook end, into the hole in drum barrel. Secure cable to drum

barrel, using setscrew furnished with winch. TIGHTEN SETSCREW SECURELY.

3. Carefully run the 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.

WINCH OPERATION

MAINTENANCE

Adhering to the following maintenance schedule will keep your winch in top condition and per-

forming 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 the gear housing cover. 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 frequently.

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 75W-90 synthetic gear oil.

4. Inspect frame and surrounding structure for cracks or deformation.

TROUBLESHOOTING GUIDE

CONDITIONS POSSIBLE CAUSE CORRECTION

OIL LEAKS FROM

WINCH

1. Seals damaged or

worn.

1. Replace seal.

2. Too much oil. 2. Drain excess oil. Refer to OPERATION.

3. Damaged gaskets. 3. Replace gaskets.

WINCH RUNS

TOO SLOW

1. Low ﬂow rate 1. Check ﬂow rate. Refer to HYDRAULIC SYS-

TEMS performance chart page 2.

2. Hydraulic motor

worn out.

2. Replace motor.

CABLE DRUM

WILL NOT FREE-

SPOOL

1. Clutch not disen-

gaged

1. Check air pressure to clutch cylinder: 100 PSI

Minimum required. Refer to page 10 for port

location.

BRAKE WLL NOT

RELEASE

1. Brake line discon-

nected or blocked.

1. Check brake function.

MAINTENANCE

2. Disconnect tube #40 from elbow #43 on valve #41 and ﬁtting #29 on brake #30b. Remove motor #33 and

gasket #30a by removing (2) capscrews #22. Remove valve #41, if needed, from motor by loosening (4)

capscrews #16.

30a

DIS-ASSEMBLY

1. Drain oil from gear housing cover by removing pipe plug #37 and relief ﬁtting #32. Remove tensioner

assembly.

INSTRUCTIONS FOR OVERHAUL

3. Remove (12) capscrews #18 to remove gear housing cover and gasket from ring gear. Remove

input thrust washer, sun gear and input carrier assembly from inside ring gear. Remove ring gear

and gasket. Remove output carrier assembly. Inspect gear housing cover bushing #15 for damage

or wear. Replace if damaged or excessive wear.

4. Remove (8) capscrews #20 to remove clutch retainer plate #10 from clutch piston. Remove

clutch #9.

5. Remove clutch housing #27 with piston #28 inside. To remove piston from clutch housing apply air to 1/8”

port. Remove o-rings #28 and #35 and inspect for damage or wear.

6. Remove (9) springs #39, thrust washer #26, gasket #31, output shaft #12 and spacer #13 from gear end

bearing. Inspect output shaft bushing #14 for damage or wear. Replace if damaged or excessive wear.

7. Remove winch tie bars #2 and #3 by removing (8) capscrews #19, (8) lock washers # 24, and (4)

shoulder bolts #25. Pull gear end bearing #7 from drum assembly #1.

8. Pull drum assembly #1 from end bearing #6. Remove quad-rings #34 from grooves in drum bush-

ings. Remove input shaft #11 from end bearing. Examine splined ends of input shaft for signs of wear,

replace if damaged. Examine drum assembly #1 for signs of wear.
