LUBRICATION
To ensure continued satisfactory operation of winch, all points
requiring lubrication must be serviced with correct lubricant at
proper time interval as indicated for each assembly.
The lubrication intervals recommended in this manual are based
on intermittent operation of winch eight hours each day, five days
per week. If winch is operated almost continuously or more than
the eight hours each day, more frequent lubrication will be
required. Also, lubricant types and change intervals are based on
operation in an environment relatively free of dust, moisture, and
corrosive fumes. Use only those lubricants recommended. Other
lubricants may affect winch performance. Approval for use of
other lubricants must be obtained from your Ingersoll
Rand
distributor. Failure to observe this precaution may result in
damage to winch and/or its associated components.

NOTICE
• Do NOT use synthetic lubricants in air motor. Synthetic
lubricants will result in oil blowing by piston rings.
Component Lubrication
General Lubrication
Correct lubrication is one of the most important factors in
maintaining efficient winch operation.
1. The recommended grade of oil must be used at all times. Use
of unsuitable oil may result in excessive temperature rise,
loss of efficiency and possible damage to lubricated
components. Refer to ‘Recommended Lubricants’ section.
2. Drain and replace oil in motor, disc brake and reduction gear
after the first 50 hours of initial winch operation. Thereafter,
drain and replace oil according to operating environment
(yearly in NORMAL and HEAVY; quarterly in SEVERE), or
more frequently if desired.
3. Always inspect removed oil for evidence of internal damage
or contamination (metal shavings, dirt, water, etc.). If
indications of damage are noted, investigate and correct
before returning winch to service.
4. After winch operation, allow oil to settle before topping off.
5. Always collect lubricants in suitable containers and dispose
of in an environmentally safe manner.
Motor
Refer to Dwg. MHP2126 on page 20.
The motor is splash lubricated by oil in motor housing and has no
other means of lubrication. It is therefore important to use only
good quality, non-detergent motor oil to ensure maximum
performance and minimum downtime for repairs. Refer to
‘Recommended Lubricants’ section.
Oil capacity for the K5B-546 motor is 3 quarts (2.8 litres). Add
oil through filler opening until oil flows from level plug hole.
Add oil slowly to prevent spilling.
The motor should be level-checked daily or at the start of each
shift after any accumulated water has been drained off. When
motors are operated in temperatures below freezing, wait long
enough at end of shift for water to separate from oil but not long
enough for it to freeze. Drain water then refill to level plug (225),
located on side of motor housing (217). If desired, all oil may be
drained at end of shift and motor refilled with new oil.
INTERVAL LUBRICATION CHECKS
Start of each shift Check flow and level of air line lubricator
(approximately 6 to 9 drops per minute
required at maximum motor speed).
Check winch motor oil level.
Monthly Lubricate components supplied by grease
fittings.
Inspect and clean or replace air line filter.
Check reduction gear oil level.
Year ly Drain and refill winch reduction gear oil.
Drain and refill winch motor oil.
Note: Intervals are based on winch operation in a normal
environment as described in the “INSPECTION” section. In
‘Heavy’ or ‘Severe’ operating conditions adjust lubrication
intervals accordingly.
