Ingersoll-Rand FA5T manual Disassembly

5.Hold cam adjustment screw in position (venting air) and tighten red setscrew.

6.If required, adjust payout limit switch. Test winch set points by operating winch through three complete cycles to ensure consistent limit switch operation within +/- 2 feet (2/3 metre) of set points.

7.Install access cover when final adjustments are complete.

Constant Tension Adjustment (optional feature)

Refer to Dwg. MHP1865 on page 12.

The regulator is preset at 0 psig (0 bar/0 kPa), therefore requires adjustment when winch is installed. To adjust for specific load applications, regulator pressure may be adjusted to increase or decrease tension setting.

Regulator gauge and regulator are accessible through cover.

WARNING

•When adjusting regulator, ensure winch control lever is locked in neutral position and tension selector lever is in the NORMAL position.

•Winch supply air is NOT shut off during regulator adjustments. To prevent accidental winch operation, allow only a single person, trained in safety, operation and maintenance of this product, to conduct regulator adjustments.

Regulator Adjustment Procedure:

Refer to Dwg. MHP1865 on page 12.

1.Attach test load of desired weight to load line, or connect load line to scale.

WARNING

•Ensure load line is connected to load and excessive slack is taken up before activating auxiliary valve. When activated, auxiliary valve will automatically engage and winch will operate at full speed to set tension on load line.

2.With winch control valve remove all slack from load line.

Setting with test load:

1.Actuate auxiliary valve to TENSIONING position. Winch should operate, causing load line to become taut. To increase tension, turn regulator knob clockwise until load begins to rise. Turn regulator knob counterclockwise a minimum of ¼ turn, or until load is balanced (does not raise or lower). Note pressure indicated on gauge for future setting reference.

Setting with scale:

1.Actuate auxiliary valve to TENSIONING position. Winch should operate, causing load line to become taut. To increase tension, turn regulator knob clockwise until scale indicates desired tension. Note pressure indicated on gauge for future setting reference.

Disassembly

General Disassembly Instructions

The following instructions provide necessary information to disassemble, inspect, repair, and assemble winch. Parts drawings are provided in parts section. If a 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 and ‘O’ rings should be discarded once they have been removed. New seals 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 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.

Winch Disassembly

Refer to Dwg. MHP0157 on page 40, MHP2093 on page 44 and MHP0152 on page 46.

1.Remove wire rope from drum.

2.Operate winch to position reduction gear drain plug at it’s lowest position.

3.Relieve pressure in air lines by operating winch control several times after air supply has been turned off.

WARNING

•Shut off, bleed down and disconnect air supply line before performing any disassembly procedures.

4.Disconnect and tag air lines.

5.Remove winch from its mounting and take to a suitable work area before beginning disassembly.

6.Remove lower case drain plug (225) on K5B motor housing (217) and allow oil to drain into a suitable container. Loosen fill cap (210) to vent motor housing.
