Ingersoll-Rand FA2A, Parts, Operation And Maintenance Manual

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 FA2A air motor is designed without an oil sump. The only
lubrication necessary for operation is that provided by a
lubricated air supply.

Any excess lubricant or moisture in the motor housing will be
discharged through the exhaust.

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.

INTERVAL

LUBRICATION CHECKS

Start of each
shift

Check flow and level of air line lubricator
(adjust flow to approximately 3 drops per
minute at maximum motor speed.).

Monthly

Inspect and clean or replace air line filter.

Check reduction gear oil level.

Yearly

Drain and refill winch reduction gear 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.

General Lubrication

1.

Drain and replace oil in the disc brake and reduction gear
after the first 50 hours of initial winch operation.
Thereafter, drain and replace oil according to the intervals
recommended.

2.

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.

3.

After winch operation, allow oil to settle before topping
off.

4.

Always collect lubricants in suitable containers and dispose
of in an environmentally safe manner.

Reduction Gear and Disc Brake Lubrication

Refer to Dwg. MHP0501.
The reduction gear and disc brake are filled with oil, from the
factory. Check oil level before initial winch operation.
These components are splash lubricated by the oil in the housing
and have no other means of lubrication. It is therefore important
to use high quality, Extreme Pressure (EP) rust and oxidation
inhibited gear oils to ensure maximum performance and
minimum down time for repairs. Oil capacity is approximately 2
quarts (1.9 litres).

Oil from the reduction gear assembly also provides lubrication
for the disc brake.
The reduction gear is vented through the disc brake breather
plug.

Initial Reduction Gear Assembly Oil Change

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.).

Lever Control Valve Lubrication

Refer to Dwg. MHP1314.
When changing the reduction gear oil, lubricate the lever control
valve at fitting (313). Use one stroke of recommended grease to
lubricate.
