K5B Motor Lubrication Locations
(Dwg. MHP2126)
Air Throttle
Refer to Dwg. MHP0165 on page 54. Periodically, depending on
winch usage and severity of environment, lubricate lever air
throttle (local and remote) with recommended grease at grease
fitting (246).
Wire Rope
Follow wire rope manufacturer’s instructions. At a minimum,
observe the following guidelines.
1. Clean with a brush or steam to remove dirt, rock dust or other
foreign material on surface of wire rope.
CAUTION
• Do not use an acid-based solvent. Only use cleaning fluids
specified by wire rope manufacturer.
2. Apply Ingersoll Rand LUBRI-LINK-GREEN
or ISO VG
100 (SAE 30W) oil as a wire rope lubricant.
3. Brush, drip or spray lubricant weekly, or more frequently,
depending on severity of service.
Reduction Gear Assembly
Refer to Dwg. MHP0140 on page 20.
It is recommend that the first oil change be done after
approximately 50 hours initial operation. Always inspect removed
oil for evidence of internal damage (metal shavings, dirt, water,
etc.).
The reduction gear is filled to the correct levels prior to shipment
from the factory. Check oil level before initial winch operation.
This component is splash lubricated by oil in the housing and has
no other means of lubrication. It is therefore important to use high
quality Extreme Pressure (EP) rust and oxidation inhibited gear oil
to ensure maximum performance and minimum down time for
repair.
CAUTION
• Do not over fill. Excess oil will reduce operating efficiency
and increase oil temperature.
To ensure correct performance, highest efficiency and long life, it
is essential that lubricating oil be maintained at correct level.
Rotate drum until fill plug is located at top dead center then add
oil up to level plug hole. Oil capacity for reduction gear assembly
is 4 quarts (3.8 litres).

Disc Brake (optional feature)
Refer to Dwg. MHP1348 on page 20.
The friction plates and drive plates are in a self contained oil bath
and have no other means lubrication. After an oil change or winch
overhaul remove the breather plug (22) and pour a small amount
of oil [4 to 6 ounces (0.2 litres)] through breather hole in brake
housing. Allow oil to fully settle between fillings.
NOTICE
• If too much oil is added excess oil will be discharged through
breather plug when control valve is actuated.

Seals and Bearings
If winch is disassembled, clean all parts thoroughly and coat
bearings and seals with clean grease. Refer to ‘Recommended
Lubricants’ section. Use sufficient grease to provide a good
protective coat. Lubricate grease fittings monthly with 2 or 3
pumps of a grease gun.
