Maintain written records of periodic inspections to provide an accumulative basis for continuing evaluation. Inspect all items listed in the ‘Frequent Inspection’ section of the Product Information Manual. Also inspect the following at the suggested intervals recommended in Table 4 ‘Maintenance Interval Chart’ on page 3:1.Siderails and Uprights. Check for deformed, cracked or corroded main

components. Replace damaged parts.

2.Fasteners. Check retainer rings, capscrews, nuts and other fasteners on winch,

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.

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.

B

(Dwg. MHP0056)

e.Inspect rope for broken strands/wires: When broken wires are evident close

to, or within, the termination, even if few in number, are indicative of high stresses at this position and can be caused by incorrect fitting of the

termination. The cause of this deterioration shall be investigated and, where possible, the termination shall be remade, shortening the rope if sufficient length remains for further use, otherwise the rope shall be discarded. One valley break may indicate internal rope deterioration, requiring closer

inspection of this section of rope. When two or more valley breaks are found in one lay length, the rope should be considered for discard. If a complete strand fracture occurs, the rope shall be immediately discarded. Where broken wires are very close together, constituting a localized grouping of such breaks, the rope shall be discarded. If the grouping of such breaks occurs in a length less than 6d or is concentrated in any one strand, it may be necessary to discard the rope even if the number of wire breaks is smaller than the maximum number, refer to table on page 2Table 3: Wire Rope

NOTICE

?Refer to Product Information and Safety Manuals for specific information. n 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 products 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 anti-seize 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 product 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.

n Disassembly

n General Disassembly Instructions

The following instructions provide necessary information to disassemble, inspect, repair, and assemble product. Parts drawings are provided in Product Parts Information Manual.

If a product is being completely disassembled for any reason, follow the order of topics as they are presented. It is recommended that all maintenance work on product be performed in a clean dust-free work area.

In the process of disassembling product, observe the following:

1.Never disassemble product 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, products are 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 and ‘O’ rings should be used when assembling product.

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 which 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

smaller than outside diameter of bearing. The end of sleeve or pipe which

contacts bearing must be square. Protect bearings from dirt by keeping them wrapped in clean cloths.

n Cleaning, Inspection and Repair

Refer to Product Parts Information Manual for item numbers referenced in the “Cleaning, Inspection and Repair” section.

n Cleaning

Clean all winch component parts in solvent (except drum brake bands and disc brake friction plates). The use of a stiff bristle brush will facilitate removal of accumulated dirt and sediments on housings, frame and drum. If bushings have been removed it may be necessary to carefully remove 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.

n Inspection

All disassembled parts should be inspected to determine their fitness for continued use. Pay particular attention to the following:

Inspect gears for

-worn, cracked or broken teeth. Replace if necessary.

Inspect bushings for

?-wear, scoring or galling. Replace if necessary.

Inspect shafts for

?-ridges caused by wear. Replace if necessary.

?-scoring or galling.

Inspect all threaded items for

?-damaged threads. Replace if necessary.

Inspect drum band brake lining for

?-oil, grease and glazing. If drum band brake lining is oil-soaked, excessively greasy or overly glazed, replace brake band. Remove small glazed areas of

band brake lining by sanding lightly with a fine grit emery cloth.

?-thickness of drum band brake lining. If drum brake band lining is less than

0.062 in. (2 mm) thick anywhere along the edges, replace brake band

assembly.

Inspect motor housing gear bores for

?-wear or scoring. For any large scratches or uneven/excessive wear patterns, replace motor housing.

Inspect motor gears (92) and (104) for

?-ridges or excessive grooving on outside diameter of gears.

?-contact between gears and gear housing.

Inspect press roller and slack wire device for

?-wear, grooves or scoring of rollers. Replace if any of these conditions exist.?-smooth rotation. Rollers must operate without binding and without excessive side-to-side play.

Inspect bearings for

?-loss of grease and evidence of grit, dirt or other contaminants. All motor bearings are factory lubricated and sealed. If dry or contaminated, replace

the bearing.

?-damage. Inspect roller bearings (needle). At any indication of damage or contamination, replace bearings.

Inspect disc brake for

?-wear. Replace brake discs if grooving pattern is no longer visible or if discs are cracked or chipped.

-thickness of disc. If less than 0.047 in (1.2 mm), replace.

n Repair

Actual repairs are limited to the removal of small burrs and other minor surface imperfections from gears, shafts, housings and machined surfaces. Use a fine stone or emery cloth for this work.

1.Worn or damaged parts must be replaced. Refer to applicable parts listing 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 edges of all shaft shoulders to remove small nicks which may have been

caused during handling.
