a. Build-up of dirt and corrosion. Clean with steam or a stiff wire brush to
remove dirt and corrosion if necessary.
b. Loose or damaged end connection. Replace if loose or damaged.
c. Check wire rope anchor is secure in drum.
d. Verify wire rope diameter. Measure the diameter of the wire rope from
crown-to-crownthroughoutthe lifeofthe wirerope.Recording of theactual
diameter should only be done with the wire rope under equivalent loading
and in the same operating section as accomplished during previous
inspections. If the actual diameter of the wire rope has decreased more than
1/64 inch (0.4 mm) a thorough examination of the wire rope should be
conducted by an experienced inspector to determine the suitability of the
wire rope to remain in service. Refer to Dwg. MHP0056 on page 2.

control valve is in the neutral position, remove valve and replace with correct
tandem center (A & B to tank) or float center motor spool (P, A & B to tank) valve.
There is excessive back pressure acting on
the reverse port of the winch motor and disc
brake charge port.
Install pressure gauges in motor lines. Run the pump at its maximum RPM and, with
the control valve in the neutral position, read the pressure gauges. Pressure greater
than 140 psig (9.6 bar/9.8 kg/cm²) is too high. Check hose and control valve size.
Replace if necessary.
Winch does not lift load or does not lift
rated capacity. Winch does not lift/pull
load.
Motor may be damaged. Remove and disassemble motor as described in “MAINTENANCE” on page 6.
Examine all parts and replace any that are worn or damaged.
Insufficient oil supply. Verify oil supply pressure and volume at winch inlet meets the requirements listed

Replace suction line if damaged. If cavitation has occurred, it is recommended that
the pump be disassembled and inspected for worn, pitted and damaged parts.
Repair and replace parts as necessary.
Relief valve is partially open. Remove relief valve and visually inspect and repair or replace worn or damaged parts.Cleanall partsthoroughlyin a suitablesolvent. Reassemble, reinstallandreset
relief valve pressure setting.
Oil leak from motor end of winch. Reduction assembly is leaking. Disassemble winch and inspect reduction assembly seals.
Motor does not run smoothly, runs hot or
makes excessive noise during operation. Air entering hydraulic system. Check hoses and hose connections.
Incorrect oil type. Replace oil with type recommended in “LUBRICATION” section in Product
Information Manual.
Winch runs slow. Improper hose or fitting sizes. Check fittings, connections and hoses for correct size and length. Replace parts that
may cause restricted line flow. Inspect filter.
Motor may be damaged. Remove and disassemble motor as recommended by the motor manufacturer.
Examine all parts and replace any that are worn or damaged.
Brake(s) not releasing. Refer to brakes in “MAINTENANCE” on page 6.

MAINTENANCE
WARNING
• Never perform maintenance on the 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 the winch, test winch to 125% of its
rated line pull at mid drum before returning to service. (Testing to more
than125%ofratedlinepullmay be required to comply with standards and
regulations set forth in areas outside the USA.)
• Shut off hydraulic system and depressurize lines before performing any
maintenance.
• Do not use Trichloroethylene to clean parts.
• Use of other than genuine Ingersoll Rand parts may result in a hazard,
decreased performance, and increased maintenance and may void all
warranties.
nGeneral
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.
nMaintenance Intervals
Refer to Table 3 ‘Decoking Winch Maintenance Interval Chart’ on page 3 for
recommended maintenance schedule.
NOTICE
• Perform an annual winch load test for all applications.
•The decoking application is considered severe conditions. The interval
chart is intended for that specific application.
nAdjustments
nGuarding
Refer to Dwg. MHP2676.
Winch guard panels must be adjusted to suit wire rope departure angle. Adjust per
procedures in Product Information Manual.
nDisc Brake
Refer to Dwg. MHP2674.
Disc brake adjustment is not required. If disc brake does not hold rated load,

complete. Bend ends of cotter pin over.
7. With brake ‘On,’ adjust screw (127) to just touch arm (124).
nHydraulic System General Maintenance
Hydraulic systems operate efficiently when properly maintained. The following
information should be developed into a routine maintenance procedure to ensure
the hydraulic system and components operate efficiently.
nHydraulic Motor
Inspect as recommended per motor manufacturer’s literature. Establish a schedule
as part of an overall maintenance schedule.
nReservoir
Maintain fluid level at all times. The fluid should be checked after the first 10 hours
of initial operation. If satisfactory, routine checks should be made each 100 hours of
operation to verify that the fluid (class and type) meets the requirements of the
pump.Changefluid every 1000to2000hours of operationdependingupon severity
of application and operating environment. If manufacturer’s requirements
recommend fluid changes sooner, follow those recommendations.
nSpare Parts
Spare filter elements should be available to allow filter replacement as necessary to
maintain a clean hydraulic oil supply. Other spare parts (hoses, fittings, etc.) should
also be available to limit equipment downtime in the event that repairs are
necessary.
nCleanliness
Keep equipment clean. A thick layer of dirt acts as insulation, causing the hydraulic
system to retain heat resulting in higher operating temperatures. If the system is
opened for inspection or repair, a clean work area prevents foreign contaminants
from entering the system and damaging component internal parts.
nFilter Maintenance
Filters must be maintained. The key to good filtration is effective filter
maintenance. Check filter condition frequently.
Keep a record of how often filters need replacing and use this record to establish a
service schedule. Routinely replacing the filter before it affects operation of the
winch reduces unexpected downtime and potential wear. A system may be
equipped with the best filters available, and the filters positioned properly so they
candothe most good,but,if the filters arenotreplaced when dirty,themoney spent
for the filters and their installation will have been wasted. A filter that gets dirty after
1dayof serviceandthen isnot cleaneduntil29 dayslaterallows 29daysof unfiltered
fluid. A filter is only as good as the maintenance given to it.
Service Suggestions:
1. Set up a filter maintenance schedule and follow it carefully.
2. Replace the original filter cartridge after 50 hours of operation.
3. Change or clean filters as required or indicated by visual indicators on filters
supplied with such devices.
a. Average Operating Environment - replace filter cartridge after each 500
hours of operation.
b. Dirty Operating Environment - replace filter cartridge after each 250 hours
of operation.
4. Clean suction strainers after first 10 hours of operation and every 100 hours
thereafter.
5. Inspect filter elements that have been removed from the system for signs of
other system damage.
6. Do not return to the system any fluid that has leaked out.
7. Always keep supplies of fresh fluid covered tightly.
8. Use clean containers, hoses and funnels when filling reservoir. Use of a filter cart
when adding fluid is highly recommended.
9. Use common sense precautions to prevent entry of dirt into components that
have been temporarily removed from the system.
10. Make sure that all cleanout holes, filler caps and breather cap filters on the
reservoir are properly fastened.
11. Donotrun the system unlessallnormally provided filtration devicesarein place.
12. Make certain that the fluid used in the system is a type recommended by the
manufacturer’s of the system or components.
6 Form MHD56375 Edition 2

The above recommendations are based on an open system equipped with micro-
air breathers. Open systems without micro-air breathers are not recommended.
Visual inspection cannot be used to determine cartridge replacement. Particles
below 40 microns are not visible to the human eye.
Before changing from one type of fluid to another (for example, from a petroleum-
base to a fire-resistant fluid) consult component and filter manufacturers on the
selection of the fluid and the filters that should be used. Follow recommended
flushing procedures when changing fluids. Also consult ANSI B93.5M-1979 “Practice
for the Use of Fire Resistant Fluids for Industrial Hydraulic Fluid Power Systems.”
nDisassembly
nGeneral Disassembly Instructions
The following instructions provide necessary information to disassemble, inspect,
repairand assemblewinch. Partsdrawings areprovided inProductPartsInformation
Manual.
If winch is being completely disassembled for any reason, follow the order of topics
as they are presented. It is recommended that all maintenance work on winch be
performed in a clean dust free work area.
In the process of disassembling winch, observe the following:
1. Never disassemble winch any further than is necessary to accomplish needed
repair. A good part can be damaged during the course of disassembly.
2. Never use excessive force when removing parts. Tapping gently around
perimeter of a cover or housing with a soft hammer, for example, is sufficient to
break the seal.
3. Do not heat a part with a flame to free it for removal unless part being heated is
already worn or damaged beyond repair and no additional damage will occur
to other parts.
In general, winch is designed to permit easy disassembly and assembly. The use
of heat or excessive force should not be required.
4. Keep work area as clean as practical to prevent dirt and other foreign matter
from getting into bearings or other moving parts.
5. All seals, gaskets and ‘O’ rings should be discarded once they have been
removed. New seals, gaskets and ‘O’ rings should be used when assembling
winch.
6. When grasping a part in a vise, always use leather-covered or copper-covered
vise jaws to protect the surface of part and help prevent distortion. This is
particularly true of threaded members, machined surfaces and housings.
7. Do not remove any part that is a press fit in or on a subassembly unless removal
of that part is necessary for repairs or replacement.
8. When removing ball bearings from shafts, it is best to use a bearing puller. When
removing bearings from housings, drive out bearing with a sleeve slightly
smallerthanoutside diameter ofbearing.The end ofsleeveorpipe that contacts
bearing must be square. Protect bearings from dirt by keeping them wrapped
in clean cloths.
nWinch Disassembly

nCleaning, Inspection and Repair
nCleaning
Clean all winch component parts in solvent (except drum brake bands). The use of
a stiff bristle brush will facilitate removal of accumulated dirt and sediments in the
reduction assembly, on housings, frame and drum. If bushings have been removed,
it may be necessary to scrape old Loctite® from bushing bores. Dry each part using
low pressure, filtered compressed air. Clean drum brake band using a wire brush or
emery cloth. Do not wash drum brake band in solvent. If drum brake band lining is
oil soaked, it must be replaced.
nInspection
All disassembled parts should be inspected to determine their fitness for continued
use. Pay particular attention to the following:
1. Inspect all gears for worn, cracked or broken teeth.
2. Inspect all bushings for wear, scoring or galling.
3. Inspect shafts for ridges caused by wear. If ridges caused by wear are apparent
on shafts, replace shaft. Inspect all surfaces on which oil seal lips seat.
4. Inspect all bearings for play, distorted races, pitting, and roller or ball wear or
damage. Inspect bearings for freedom of rotation.
5. Inspect all threaded items and replace those having damaged threads.
6. Inspect drum band brake lining for oil, grease and glazing. If drum band brake
lining is oil-soaked, replace brake bands as a set. Remove glazed areas of band
brake lining by sanding lightly with a fine grit emery cloth.
7. Measure thickness of drum band brake lining. If drum brake band linings are less
than 0.062 in. (2 mm) thick anywhere along edges replace brake bands (128) as
a set.
nRepair
Actual repairs are limited to removal of small burrs and other minor surface
imperfections from gears and shafts. Use a fine stone or emery cloth for this work.
Do not use steel wool.
1. Worn or damaged parts must be replaced. Refer to the applicable Parts Listing
for specific replacement parts information.
2. Inspect all remaining parts for evidence of damage. Replace or repair any part
that is in questionable condition. Cost of the part is often minor in comparison
with cost of redoing job.
3. Smooth out all nicks, burrs or galled spots on shafts, bores, pins or bushings.
4. Examine all gear teeth carefully, and remove nicks or burrs.
5. Polishedgesofallshaft shoulderstoremovesmallnicks causedduringhandling.
