MAINTENANCE
WARNING
• Never perform maintenance on winch while it is supporting a load.
• Before performing maintenance, tag controls:
WARNING - DO NOT OPERATE -
EQUIPMENT BEING REPAIRED
• Only allow Ingersoll Rand trained Service Technicians to perform
maintenance on this winch.
• After performing any maintenance on winch, test winch to 125% of its rated
line pull at mid drum before returning to service. (Testing to more than 125%
of rated line pull may be required to comply with standards and regulations set
forth in areas outside the USA.)
• Shut off air system and depressurize air lines before performing any
maintenance.
• Do not use Trichloroethylene to clean parts.
• Use of other than genuine Ingersoll Rand parts may result in safety hazards,
decreased performance and increased maintenance and will invalidate all
warranties.

General
Correct disassembly (to prevent loss or damage of good parts), repair, assembly,
testing and adjusting are critical to proper winch operation. Maintenance procedures
are technical in nature and require training and experience to accomplish correctly.
In addition, repair and testing require specialized equipment that is not typically
found at the winch-mounting site.
Proper use, inspections and maintenance increase the life and usefulness of your
Ingersoll Rand equipment. During assembly, lubricate gears, nuts, capscrews and all
machined threads with applicable lubricants. Use of antiseize compound and/or
thread lubricant on capscrew and nut threaded areas prevents corrosion and allows
for easy disassembly of components.
It is extremely important that anyone involved with maintaining the winch be
familiar with the servicing procedures of these winches and be physically capable of
conducting the procedures. These personnel shall have skills that include:
1. Proper and safe use and application of mechanics common hand tools as well as
special Ingersoll Rand or recommended tools.
2. Safety procedures, precautions and work habits established by accepted industry
standards.
Ingersoll Rand cannot know of, or provide all the procedures by which product
operations or repairs may be conducted and the hazards and/or results of each
method. If operation or maintenance procedures not specifically recommended by
the manufacturer are conducted, it must be ensured that product safety is not
endangered by the actions taken. If unsure of an operation or maintenance
procedure or step, personnel should place the product in a safe condition and
contact supervisors and/or the factory for technical assistance.
NOTICE
• Refer to the Product Parts Information Manual for drawings unless specified
elsewhere.

Adjustments
„
Drum Guard
Refer to Dwg. MHP2676.
Drum guard panels must be adjusted to suit wire rope departure angle. Adjust per
procedures in Product Information Manual.
„
Disc Brake
Refer to Dwg. MHP2786.
Disc brake adjustment is not required. If disc brake does not hold rated load
disassemble and repair. If brake assembly is removed or disassembled ensure breather
(29) is installed and located at top of brake housing during reassembly.
„
Manual Drum Band Brake
Refer to Dwg. MHP0209.
1. Release wire rope tension on drum.
2. Raise handle (104) to free brake bands (128).
3. Remove cotter pin (102) and pin (101).
4. Rotate link stud (103) clockwise to increase brake torque.
5. Install pin (101) and check adjustment.
6. Brake should be adjusted until brake lever over center position can be attained
with 50 to 100 lb (23 to 45 kg) force on handle (104).
7. Install cotter pin (102) when adjustment is completed. Bend ends of cotter pin
over.
CAUTION
• When any part of brake lining measures 0.062 inch (2 mm) or less, brake
bands (128) or linings must be replaced.
„
Automatic Band Brake
Refer to Dwg. MHP0209.
1. Remove cotter pin (102) at adjustment clevis (107).
2. Apply air to brake cylinder (110) and remove pin (106) to disconnect clevis from
brake lever (105).
3. Turn adjustment clevis (107) clockwise to increase cylinder rod extension. Turn
clevis counterclockwise to decrease cylinder rod extension.
4. Assemble clevis (107) to brake lever (105) with pin (106). Release air to brake
cylinder (110).
5. Measure cylinder rod extension. Length should be 1 to 1-1/2 inches (25 to 37
mm). Re-adjust if necessary.
6. Install cotter pin (102) to secure clevis to brake lever when adjustment is
complete. Bend ends of cotter pin over.
7. With brake on , adjust screw (127) to just touch arm (124).

Pilot Air Control Valve (optional feature)
Not shown in Product Parts Information manual.
If winch operating speeds differ from performance specifications, pilot air control
valve may require adjustment.
1. Loosen nut (271) and adjust adjusting screw (270), located in valve end
cap(268), until drum speed for no-load haul-in equals drum speed for full load
payout.
2. Rotate screw (270) ‘ out’ to increase drum speed and ‘in’ to decrease drum speed.
It is suggested that a chalk mark be placed on drum flange so that drum rpm can
be accurately counted.
3. Tighten nut (271) after adjustment.
Automatic Band Brake:
Brake cylinder will not release. Band brake out of adjustment. Adjust band brake to maintain correct cylinder stroke.
Leaking cylinder seals. If air is noticed escaping from cylinder breather when attempting to release brake,
replace or repair cylinder.
Dirty filter in air supply. Clean or replace filter.
Faulty dump valve. Check dump valve exhaust port. Air should exhaust when control valve handle is in
neutral. If no air escapes, replace dump valve.
Automatic Disc Brake:
Brake fails to release. Low air supply pressure. Ensure air pressure at inlet to disc brake is at least 60 psig (3.4 bar/340 kPa).
Leaking piston seals. Inspect brake breather. If air escapes from brake breather when attempting to release
brake, replace brake seals.
No release pressure at brake port. Check for proper operation of winch controls.
Sticking brake piston. Apply 60 psig (3.4 bar/340 kPa) to brake release port and check for brake disc
movement. (Brake discs can be viewed through brake breather hole.) If brake discs do
not move, disassemble and inspect disc brake as described in “MAINTENANCE” section on
page 6.
