INSPECTION
Perform frequent inspections on equipment in regular service. Refer to Product
Information Manual.
Periodic Inspection
Refer to Table 2, ’Inspection Classifications,’ on page 2 for suggested winch
inspection classifications for Periodic Inspection intervals. Select inspection periods
most appropriate to application conditions.
Maintain written records of periodic inspections to provide an accumulative basis for
continuing evaluation. Inspect all items listed in ‘Frequent Inspection’ section of the
Product Information Manual. Also inspect the following at the suggested intervals
recommended in Table 3, ’Maintenance Interval Chart,’ on page 3:
1. Siderails, Spacers, Uprights and Skid. Check for deformed, cracked or corroded
main components. Replace damaged parts.
2. Fasteners. Check retainer rings, capscrews, nuts and other fasteners, including
mounting bolts. Replace if missing or damaged and tighten if loose.
3. Drum and Sheaves. Check for cracks, wear or damage. Replace if necessary.
4. Wire Rope. In addition to ‘Frequent Inspection’ requirements, also inspect for
the following:
a. Build-up of dirt and corrosion. Clean with steam or a stiff wire brush to
remove dirt and corrosion if necessary. Lubricate after cleaning.
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-crown throughout the life of the wire rope. Recording of the
actual 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,
A. Wire; B. Crown to Crown; C. Strand; D. One Lay.
(Dwg. MHP0056)
5. All Components. Inspect for wear, damage, distortion, deformation and
cleanliness. If external evidence indicates damage, disassemble as required to
conduct a detailed inspection. Inspect gears, shafts, bearings, sheaves, springs
and covers. Replace worn or damaged parts. Clean, lubricate and reassemble.
6. Brakes. Individually test brakes installed to ensure proper operation. Brakes
must hold a 125% rated load at mid drum without slipping. If indicated by poor
operation or visual damage, disassemble and repair brake(s). Check all brake
surfaces for wear, deformation or foreign deposits. Clean and replace components
as necessary. Adjustments can be made to the drum band brake to compensate
for normal brake lining wear. Refer to ‘Adjustments’ in the “MAINTENANCE”
section. If brake band cannot be adjusted to hold rated load, replace the brake
band assembly. Adjustments cannot be made to the disc brake. The disc brake
must be repaired as described in the “MAINTENANCE” section.
7. Foundation or Supporting Structure. Check for distortion, wear and continued
ability to support winch and rated load. Ensure winch is firmly mounted and that
fasteners are in good condition and tight.
8. Control Valve. Check control valve operation. Ensure control valve handle moves
freely in both directions without sticking and automatically returns to neutral
when released.
9. System Relief Valve. Ensure hydraulic relief valve is properly set to stop the
winch when loads exceed 150% (+/- 25%) of winch rated capacity. If winch does
not shut down, contact your distributor or the factory for repair information.
10. Slack Line Detector. Inspect rollers for wear and grooves or ridges. Replace worn
or grooved rollers. Check arms move freely and activate sensor valve. Ensure
rollers rotate freely. Check sensor valve plunger operation. If damaged or stiff
replace sensor valve.
11. Press Roller. Inspect rollers for wear and grooves or ridges. Ensure rollers rotate
freely. Lubricate roller bores if rotation is rough or stiff. Check springs keep press
rollers tight against wire rope drum diameter.
12. Emergency Lowering Device. Provide auxilary supply air to emergency lowering
power entry port and activate valve. Verify winch operation.
13. Winch Guard. Verify fasteners are tight and in good condition. Ensure guard is in
good condition.
14. Labels and Tags. Check for presence and legibility of labels. Replace if damaged
or missing.
Records and Reports
Inspection records, listing all points requiring periodic inspection should be
maintained for all load bearing equipment. Written reports, based on severity of
service, should be made on the condition of critical parts as a method of
documenting periodic inspections. These reports should be dated, signed by the
person who performed the inspection, and kept on file where they are readily
available for review.

TROUBLESHOOTING
This section provides basic troubleshooting information. Determination of specific causes to problems are best identified by thorough inspections performed by Ingersoll Rand
trained technicians. The chart below provides a brief guide to common winch symptoms, probable causes and remedies.
SYMPTOM CAUSE REMEDY
Winch will not operate. Insufficient oil supply. Verify oil supply pressure and volume at winch inlet meets the requirements listed
in the “SPECIFICATIONS” section in Product Information Manual. Clean oil filter.
Winch is overloaded. Reduce load to within rated capacity.
Disc brake does not release. Pressurize disc brake release port and check for excessive leakage from the case
drain port. If excessive leakage is noted disassemble and repair motor as
recommended by the motor manufacturer.
Shipping plugs may still be in place. Remove shipping plugs in valve and motor ports.
Motor may be damaged. Disassemble and clean the motor and replace any broken or damaged parts.
System relief valves set too low. Adjust system relief valves to meets the requirements listed in the
“SPECIFICATIONS” section in Product Information Manual.
Load continues to move when winch is
stopped.
Brake is slipping. Check brake friction disc wear.
Winch is overloaded. Reduce load to within rated capacity.
Control valve may not be correct type. The
correct control valve should have all ports
open to reservoir when the spool is in the
neutral position.
If the motor ports in the valve are blocked by the spool (closed center) when the
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.
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.
Insufficient oil supply. Verify oil supply pressure and volume at winch inlet meets the requirements listed
in the “SPECIFICATIONS” section in Product Information Manual. Clean oil filter.
No oil supply to winch. Check oil supply line connections, hoses and valves.
Winch is overloaded. Reduce load to within rated capacity.
System not delivering full pressure to
winch.
Confirm pump is running and on stroke. Check upline flow controls are set as
required to run the winch.
Relief valve dumps full pressure. Confirm no downline restrictions of valves are blocking free flow back to tank.
Relief valve set too low. Install pressure gauges in motor lines and apply a stall pull on the winch. If
pressure is low, increase relief valve setting until recommended pressure is
obtained.
Relief valve is partially open. Remove relief valve and visually inspect and repair or replace worn or damaged
parts. Clean all parts thoroughly in a suitable solvent. Reassemble, reinstall and
reset relief valve pressure setting.
Oil level in reservoir too low. Suction
line may be restricted or have an air
leak causing cavitation at the inlet
pump. ‘Whining’ noise at pump is an
indication of this problem.
Check oil level in reservoir. Check suction line externally and internally for damage.
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.
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 oil flow. Inspect oil 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” section on page 6.
Insufficient oil supply. Verify oil supply pressure and volume at winch inlet meets the requirements. Refer
to “SPECIFICATIONS” section in Product Information Manual. Clean oil filter.
Hydraulic oil may be cold. Run hydraulic pump to warm and circulate oil through system.
Control valve lever hard to actuate, or
lever does not spring return to neutral.
Valve spool sticking. Remove and disassemble control valve. Repair control valve as recommended by
the valve manufacturer.

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 technicians to perform maintenance on
this product.
• 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 than
125% of rated line pull may 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 safety hazards,
decreased performance, and increased maintenance and may 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 products, 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.
Adjustments
Disc Brake
Disc brake adjustment is not required. If disc brake does not hold rated load,
disassemble and repair.
If brake slippage occurs during tests prior to placing winch in service or during
normal use of the winch, follow the winch disassembly procedure and check brake
wear.
1. Inspect the brake friction plate (55) for wear. Friction plates (55) have 0.008 in
(0.2 mm) deep grooves on each side. Replace the friction plates (55) if grooves
are no longer visible.
2. Measure total friction plate (55) and steel plate (56) stack up. Check that
measurement is not less than 0.268 in (6.80 mm). Refer to Dwg. MHP3082 on
page 6.
(Dwg. MHP3082)
NOTICE
• Original friction plate thickness is 0.059 in (1.5 mm).
Automatic Band Brake
Refer to Dwg. MHP3088 on page 6.
1. Loosen locknut ‘B’.
2. Tighten nut ‘A’ until one of the adjustment dimensions is achieved.
3. Tighten locknut ‘B’.
4. Check brake operation.

Overload Device
Refer to Dwg. MHP2330 on page 7, A. Adjust Torque Limiter Valve to Limit Winch Lift
Capacity to 125% of the SWL.
CAUTION
• Overload is factory set and should not be adjusted without consulting an
Ingersoll Rand trained technician.
(Dwg. MHP2330)
1. Connect winch to the hydraulic supply.
2. Release securing screw and adjusting screw in order to increase or decrease the
SWL (increase SWL by tightening adjusting screw on torque limiter valve).
Adjustment must be made for an overload of 25% maximum of SWL.
3. Tighten securing screw.
Hydraulic System General Maintenance
The hydraulic hoses must be clean and free from moisture. Hydraulic inlet ports sizes
are 1/2” BSP. The inside diameter of the hydraulic supply lines must not be smaller
than 1/2”. Before making the final connections all hydraulic supply lines should be
purged. Supply lines should be as short and straight as installation conditions will
permit. Long transmission lines and excessive use of fitting, elbows, tees, etc. cause
head loss.
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.
Hydraulic Motor
Inspect as recommended per motor manufacturer’s literature. Establish a schedule as
part of an overall maintenance schedule.
Reservoir
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. Change fluid every 1000 to 2000 hours of operation depending upon severity
of application and operating environment. If manufacturer’s requirements
recommend fluid changes sooner, follow those recommendations.
Spare 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.
Cleanliness
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.
Filter 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 can do the
most good, but, if the filters are not replaced when dirty, the money spent for the
filters and their installation will have been wasted. A filter that gets dirty after 1 day
of service and then is not cleaned until 29 days later allows 29 days of 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 clean-out holes, filler caps and breather cap filters on the
reservoir are properly fastened.
11. Do not run the system unless all normally provided filtration devices are in place.
12. Make certain that the fluid used in the system is a type recommended by the
manufacturers’ of the system or components.
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.”
Disassembly
NOTICE
• Refer to the Product Parts Information Manual for drawing and item numbers
referenced in the “MAINTENANCE” section.
General Disassembly Instructions
The following instructions provide the necessary information to disassemble, inspect,
repair, and assemble winch. Parts drawings are provided in the Product Parts
Information 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 the winch be
performed in a clean dust free work area.
In the process of disassembling the 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 the winch.

6. When grasping a part in a vise, always use leather-covered or copper-covered
vise jaws to protect the surface of the 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 the
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 smaller
than outside diameter of bearing. The end of sleeve or pipe that contacts
bearing must be square. Protect bearings from dirt by keeping them wrapped in
clean cloths.

Cleaning, Inspection and Repair
Cleaning
CAUTION
• A bearing that appears loose or does not rotate smoothly must be replaced.
Failure to observe this precaution will result in bearing and/or winch
component damage.
Clean all winch component parts in solvent (except for the brake friction discs). The
use of a stiff bristle brush will facilitate the removal of accumulated dirt and
sediments in the drum and reduction assembly. If drum wear rings have been
removed it may be necessary to carefully scrape old Loctite® from the drum wear ring
grooves. Dry each part using low pressure, filtered compressed air. Clean the brake
friction discs using a wire brush or emery cloth. Do not wash the brake friction discs
in liquid. If the brake friction discs are oil soaked, they must be replaced.
Inspection
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 all bearings for play, distorted races, pitting and roller or ball wear or
damage. Inspect bearings for freedom of rotation.
4. Inspect shafts for ridges caused by wear. If ridges caused by wear are apparent
on shafts, replace the shaft. Inspect all surfaces on which oil seal lips seat.
These surfaces must be very smooth to prevent damage to the seal lip.
5. Inspect all threaded items and replace those having damaged threads.
6. Inspect the brake stationary plates and friction discs for oil. If the stationary
plates have become glazed, sand them lightly using fine emery cloth and a flat
surface as backing. Inspect the remaining brake parts for warpage or other
damage, and replace damaged parts as necessary.
7. Measure the thickness of the brake friction discs. The brake friction discs must
show an even wear pattern. If the brake friction discs are 0.047 in (1.2 mm) or
less, replace the discs.
Repair
Actual repairs are limited to the 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 Product Parts Information
Manual for specific replacement parts information.
2. Inspect all remaining parts for evidence of damage. Replace or repair any part
which is in questionable condition. The cost of the part is often minor in
comparison with the cost of redoing the 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. Polish the edges of all shaft shoulders to remove small nicks which may have
been caused during handling.
6. Remove all nicks and burrs caused by lockwashers.
7. Replace all gaskets, oil seals, and ‘O’ rings removed during winch disassembly.

confirming the rating of the winch. Test loads shall not be less than 100% of rated
line pull and should not exceed 125% of the rated line pull. Testing to more than
125% of rated capacity may be required to comply with standards outside of the
USA.
The minimum load test for European countries are according to the information
below. If not found below you should use the tests recommended by FEM.
The dynamic test shall be carried out with an overload coefficient 1 = 1,2 i.e. with a
load equal to 120% of the safe working load. All motions shall be carefully operated
in turn, without checking speeds of temperature rises in the motors.
The static test shall be carried out with an overload coefficient 2 = 1,4 i.e. with a
load equal to 140% of the safe working load. The test must be carried out under still
conditions and consists of hoisting the safe working load a small distance above the
