TROUBLESHOOTING (CONTINUED)
LUBRICATION
To ensure continued satisfactory operation of the winch, all points
requiring lubrication must be serviced with correct lubricant at the
proper time interval as indicated for each assembly.
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 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 performance of 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 its associated components.
Note: Intervals are based on winch operation in a normal
environment as described in “INSPECTION” section. In ‘Heavy’
or ‘Severe’ operating conditions adjust lubrication intervals
accordingly.
General Lubrication
1. Drain and replace oil in the motor, disc brake and reduction
gear after the first 50 hours of initial winch operation.
Thereafter, drain and replace oil according to 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 on page 22.
The reduction gear and disc brake are filled and shipped 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 3 quarts (2.8
litres). Oil from the reduction gear assembly also provides
lubrication for the disc brake.
On winches equipped with a disc brake, the reduction gear is
vented through the disc brake breather plug.
Recommended Lubricant
* Units are shipped from factory with ISO VG 100 (SAE 3 EP)
lubricant. Reduction Gear capacity is approximately 3 quarts
(2.8 litres).
Recommended Grease
Automatic Band Brake:
Brake cylinder will not
release.
Band brake out of adjustment. Adjust band brake to maintain correct cylinder stroke.
Leaking cylinder seals. If air is noticed escaping from cinder breather when attempting to release
brake, replace or repair cylinder.
Dirty filter in air supply. Clean or replace filter.
Faulty dump valve. Check dump valve exhaust port. Air should exhaust when control valve
handle is neutral. If no air escapes, replace dump valve.
Automatic Disc Brake:
Brake fails to release. Low air supply pressure. Ensure air pressure at inlet to disc brake is at least 50 psig (3.4 bar/340 kPa).
Leaking piston seals. Inspect brake breather. If air escapes from brake breather when attempting to
release brake, replace brake seals.
No release pressure at brake port. Check for proper operation of winch controls.
Sticking brake piston. Apply 50 psig (3.4 bar/340 kPa) to brake release port and check for brake
disc movement. (Brake discs can be viewed through brake breather hole.)
If brake discs do not move, disassemble and inspect disc brake as described
in “MAINTENANCE” section.
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.
Yearly Drain and refill winch reduction gear oil.
Drain and refill winch motor oil.
