MAINTENANCE

WARNING

Never perform maintenance on winch while it is supporting a load.

Before performing maintenance, tag controls:

WARNING - DO NOT OPERATE -

EQUIPMENT BEING REPAIRED.

Only allow service personnel trained in safety and service on this winch to perform maintenance.

After performing any maintenance on winch, test winch to 125% of its rated capacity before returning to service. Testing to more than 125% of rated capacity may be required to comply with standards outside the USA.

Shut off air system and depressurize air lines before performing any maintenance.

Maintenance Intervals

The Maintenance Interval chart is based on intermittent operation of winch eight hours each day, five days per week. If winch operation exceeds eight hours per day, or use is under HEAVY or SEVERE conditions, more frequent maintenance should be performed. Refer to ‘Periodic Inspection’ on page 22 in “INSPECTION” section for interval guidance.

Adjustments

 

 

 

 

Disc Brake Adjustment (optional feature)

Refer to Dwg. MHP0152 on page 46.

Disc brake adjustment is not required. If disc brake does not hold rated load disassemble and repair.

If brake assembly is removed or disassembled ensure breather (23) is installed and located at top of brake housing during reassembly.

Manual Drum Brake Adjustment

Refer to Dwg. MHP0153 on page 48.

1.Release wire rope tension on drum.

2.Raise handle (104) to free brake bands (128).

3.Remove cotter pin (102) and pin (101).

4.Rotate link stud (103) clockwise to increase brake torque.

5.Install pin (101) and check adjustment.

6.Brake should be adjusted until brake lever over center position can be attained with 50 to 100 lb. (23 to 45 kg) force on handle (104).

7.Install cotter pin (102) when adjustment is completed. Bend ends of cotter pin over.

CAUTION

When any part of brake lining measures 0.062 inch (2 mm) or less, brake bands (128) or linings must be replaced.

Automatic Drum Brake Adjustment (optional feature)

Refer to Dwg. MHP0153 on page 48.

1.Remove cotter pin (102) and washer (129) at adjustment clevis (107).

2.Apply air to brake cylinder (110) and remove pin (106) and second washer (129) to disconnect clevis from brake lever

3.Turn adjustment clevis (107) clockwise to increase cylinder rod extension. Turn clevis counterclockwise to decrease cylinder rod extension.

4.Assemble clevis (107) to brake lever (105) with washer

(129)and pin (106). Release air to brake cylinder (110).

5.Measure cylinder rod extension. Length should be 1 to 1-1/2 inches (25 to 37 mm). Readjust if necessary.

6.Install cotter pin (102) and second washer (129) to secure clevis to brake lever when adjustment is complete.

7.With brake “On”, adjust screw (127) to just touch arm (124).

Pilot Air Control Valve Adjustment (optional feature)

Refer to Dwg. MHP0141 on page 60.

If winch operating speeds differ from performance specifications pilot air control valve may require adjustment. Loosen nut (271) and adjust adjusting screw (270), located in valve end cap (268), until drum speed for no-load haul-in equals drum speed for full load payout. Rotate screw (270) ‘out’ to increase drum speed and ‘in’ to decrease drum speed. It is suggested that a chalk mark be placed on drum flange so that drum rpm can be accurately counted.

Overload Valve Adjustment (optional feature)

new style

Refer to Dwg. MP2216 on page 27

5/16 in. or 8 mm open ended wrench required.

1.Adjust overload valve by turning adjustment screw located at bottom of control valve.

2.Rotating adjustment screw clockwise will increase pressure required to activate overload valve.

WARNING

This adjustment can cause overload device to NOT activate before winch’s safety limit is exceeded. This procedure should only be done by personnel trained in testing and servicing this winch.
