General Machine Products 70524 Adams CD3 Continuous Duty Winch - Manual (Page 14)

AK 7/18/2012 ver 5
If the winch has not been used for an extended period of time, inspect the interiors of the drive housing and final
drive housing for water deposits and rust due to the elements or condensation. Particular attention should be given
to any damaged bearings, seals or gaskets. The oil should be checked for contamination, abrasive foreign particles
and lubrication qualities. As required, oil should be added or completely drained and filled.
The wire rope should be inspected visually for kinks, bends, cuts or broken strands while operating. Wire rope that
does not meet OSHA criteria must be replaced.
Depending on the total length of the wire rope versus the length most often used, it is possible that the top lays will
show the most wear. To obtain additional life, subject to the proper conditions, the rope can be rotated end for end.
The hydraulic system should be checked periodically for:
♦ Overheating
♦ Abnormal noise
♦ Maintaining a clean, sufficient, quantity of hydraulic oil of the proper grade.
♦ Keeping all connections sufficiently tight to prevent oil leakage and air from entering the system.
♦ Changing the hydraulic system oil filter at the frequency recommended by the filter manufacturer.
IMPORTANT - BEFORE THE WINCH IS ACTUATED, THE FULL LOAD BRAKE MUST BE
BLED. See Section 3.05 Full Load Brake.
WARNING - THE FULL LOAD BRAKE MAY NOT HOLD THE RATED LOAD IF THE CASE
DRAIN IS LEAKING FLUID.
IMPORTANT - THE LOAD HOLDING ABILITY OF THE FULL LOAD BRAKE SHOULD BE
TESTED ON A PERIODIC BASIS.
6.02 LUBRICATION - An ongoing routine for assuring proper lubrication should be a part of the overall
maintenance program.
The gearbox oil reservoir must be checked and main-
tained. To check for the proper oil level, examine the sight
gauge on the front of the gearbox. The lubricant level
should be maintained to the middle of the oil level sight
gauge. To add oil, remove the filler plug in the gearbox
cover. Add 80W 140 oil as required to bring the oil level
up to the middle of the sight gauge. Do not overfill!
Screw the filler plug back into the gearbox cover.
The gearbox oil level should be checked every seventy-
five (75) hours of operation and should be completely
drained and filled with new oil at least every other year.
The drain plug is located on the underside of the gearbox.
To drain the gearbox, remove the oil drain plug located on
the underside of the gearbox. Remove the filler plug in
the gearbox cover. After the gearbox is completely
drained, reinstall the oil drain plug. Add six (6) U.S. gal-
lons (22,7
l) of fresh 80W140 oil as described above and
reinstall filler plug.
