3.

Allow the repaired area to cool. Quenching with water is
acceptable. Inspect the repair. Rough spots, minor
scorching and excess coating deposits can be wet sanded to
remove the imperfections. To return the gloss finish, reheat
the surface carefully.

For large bare surfaces or new parts:
Coating these components can be done more economically and
with better end results by using an electrostatic powder
application process or flamespray process. Contact
Ingersoll-Rand Technical Assistance for more information.

For specific disassembly and assembly information refer to
‘Assembly’ or ‘Disassembly’ in the “MAINTENANCE” section.

Adjustments

Disc Brake

Brake adjustment is not required. If the disc brake does not hold
100% of rated load at mid drum, disassemble and repair.

NOTICE

• Winches are provided with a breather plug located at the
top of the disc brake housing. If the brake assembly is
removed or repaired ensure the breather is installed and
located at the top of the brake housing during reassembly.

Manual Drum Band Brake

Optional feature. Refer to Dwg. MHP1372.
1.

Release wire rope tension on the drum.

2.

Raise handle (135) to free brake bands (136 and 137).

3.

Remove cotter pin (139) and pin (138).

4.

Rotate brake link stud (141) clockwise to increase brake
torque.

5.

Install pin (138) and check adjustment.

NOTICE

• If brake band cannot be adjusted to hold the rated load,
replace the brake band assembly.

6.

Adjust brake so when brake handle locks (goes over-
center), brake will hold rated load.

7.

Install cotter pin (139) when adjustment is complete.

8.

Lift up the brake handle to free position.

9.

Loosen capscrew (101) and rotate cam stop until both ends
of the brake band are an equal distance from the drum
brake band surface.

10. Tighten capscrew (101).

Automatic Drum Band Brake

Optional feature. Refer to Dwg. MHP1281.
For adjustments, references to “clockwise” and
“counterclockwise” directions, in the text, refer to directions as
viewed from the head end of capscrew (120).

NOTICE

• If brake band cannot be adjusted to hold rated load, replace
the brake band assembly.

1.

Loosen jam nut (117) closest to plunger (114).

2.

Adjust band assembly using capscrew (120).
a.

To loosen band brake, turn capscrew (120) in the
counterclockwise direction.

b.

To tighten band brake, turn capscrew (120) in the
clockwise direction.

NOTICE

• If the capscrew (120) is not accessible, the jam nut (117)
[located closest to the head of capscrew (120)] may be used to
adjust the band brake. Ensure capscrew turns with nut.

3.

When adjustments are complete tighten jam nut (117)
closest to plunger (114).

Remote Pendant Control Valve Adjustment

Optional feature. Refer to Dwg. MHP1305.
If winch operating speeds differ from performance specifications
the pilot air control valve may require adjustment.
1.

Loosen nut (271) and adjust adjusting screw (270), located
in the valve end cap (268). Screw in to slow payout speed;
screw out to increase payout speed.

NOTICE

• Turning adjusting screw (270) clockwise (in) decreases
payout speed. Counterclockwise (out) increased payout
speed. It is suggested that a chalk mark be placed on the
drum flange so that drum rpm can be accurately counted.

2.

Adjust until drum speed for no-load haul-in equals the
drum speed for full load payout.

Disassembly

General Disassembly Instructions

The following instructions provide the necessary information to
disassemble, inspect, repair, and assemble the winch. Parts
drawings are provided in the Parts Section.
If a winch is being completely disassembled for any reason,
follow the order of the 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 the winch any further than is necessary
to accomplish the needed repair. A good part can be
damaged during the course of disassembly.

2.

Never use excessive force when removing parts. Tapping
gently around the 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 the part being heated is already worn or damaged
beyond repair and no additional damage will occur to other
parts.

In general, the winch is designed to permit easy disassembly and
assembly. The use of heat or excessive force should not be
required.

4.

Keep the work area as clean as practical, to prevent dirt and
other foreign matter from getting into bearings or other
moving parts.
