Refer to Dwg. MHP0165on page 54.

NOTICE

Match mark throttle valve parts to ensure proper re- assembly.

1.Remove two capscrews (302) and lockwashers (96) that hold the valve body retainer (305).

2.Mark square end on valve body (316) and handle (300) to ensure correct orientation during reassembly.

3.Drive out pin (301) and remove handle (300).

4.Make note on how spring (303) is positioned before removing it. Pull valve body (316) out of valve bushing (314) while disconnecting spring (303).

5.Remove seal rings (315) from valve body (316).

6.Check parts for score marks or wear.

7.Measure clearance between valve bushing (314) and valve body (316). Clearance between valve bushing and valve body should not exceed 0.002 inch (0.05 mm) or excessive air leakage will occur.

K5C2-E Control Valve Disassembly

Refer to Dwg. MHP 2180 on page 52.

Handle Removal

Follow disassembly instructions for K5C2 Control Valve.

Reverse Valve Removal

1.Remove capscrews (938), (925) and washers (924) from seal bracket (939). Remove seal bracket from housing. Remove and discard ‘O’ rings (941) and (942).

2.Remove capscrews (721) and washers (902) from exhaust flange (955) and exhaust adapter (723). Remove and discard ‘O’ rings (942) and (722).

3.Move reverse valve (943) out exhaust flange side of housing until ball (916) is visible on reverse valve. Allow ball (916) to drop out of bushing (944) and remove ball (916).

4.Remove bushing (944) out exhaust flange side of housing.

NOTICE

Dowel pin (945) allows the bushing to be removed only from the exhaust flange side of housing. Ball (916) retains reverse valve (943) in bushing (944).

Do not remove reverse valve (943), bushing (944) and ball (916) at the same time, damage may occur to bushing.

Piston Removal

Follow disassembly instructions for K5C2 Control Valve.

Pilot Valve Removal

Follow disassembly instructions for K5C2 Control Valve.

Emergency Stop Removal

1.Remove adapter (706) and E-Stop button (705).

2.Remove plunger (707). Remove and discard ‘O’ rings (703).

3.Pull spring (711) out of valve housing and discard.

Overload Valve Removal

1.Remove cap (700). Remove and discard grommet (701).

2.Pull out plunger (702), remove and discard ‘O’ rings (703).

3.Remove capscrews (901) and washers (902) from cover (719) underneath valve housing.

NOTICE

Cover (719) retains spring (718). To remove capscrews (901) and washer (902) unscrew in a crisscross pattern.

4.Remove adjusting screw (720).

Cleaning, Inspection and Repair

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 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.

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 shafts for ridges caused by wear. If ridges caused by wear are apparent on shafts, replace shaft.

4.Inspect all threaded items and replace those having damaged threads.
