LUBRICATION
To ensure continued satisfactory operation of the winch, all points
requiring lubrication must be serviced with the correct lubricant at
the proper time interval as indicated for each assembly.
The lubrication intervals recommended in this manual are based
on intermittent operation of the winch eight hours each day, five
days per week. If the winch is operated almost continuously or
more than the eight hours each day, more frequent lubrication will
be required. Also, the 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 the performance of the
winch. Approval for the use of other lubricants must be obtained
from your Ingersoll-Rand distributor. Failure to observe this
precaution may result in damage to the winch and/or its
associated components.
Note: Intervals are based on winch operation in a normal
environment. In ‘Heavy’ or ‘Severe’ operating conditions adjust
lubrication intervals accordingly.

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
since the use of unsuitable oil may result in excessive
temperature rise, loss of efficiency and possible damage to
internal components. Refer to the “Recommended
Lubricants” section.
2.
Drain and replace oil in the reduction gear after the first 50
hours of initial winch operation. Thereafter, drain and
replace oil according to the operating environment as defined
by the “Periodic Inspection” interval table in the
“INSPECTION” section, 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 drain oil into a suitable container and dispose of in
an environmentally safe manner.
Oil Capacities
Reduction Gear Assembly
Refer to Dwg. MHP1756 on page 13.
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 inhibiting 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 the lubricating oil be maintained at the correct
level. Rotate the drum until one of the removable plugs is located
at top dead center then add oil up to the level plug hole. Oil
capacity for the reduction gear assembly is 4 qts (3.8 litres).
