WINCH MAINTENANCE
Adhering to the following maintenance schedule will keep your winch in top condit ion and performing
as it should with a minimum of repair.
A. WEEKLY
1. Check the oil level and maintain it to the oil level plug. If oil is leaking out, determine location and
repair.
2. Check the pressure relief plug in top of the gear housing. Be sure that it is in good operating condi-
tion so that hot oil gasses may escape.
3. Lubricate cable with light oil..
B. MONTHLY
1. Lubricate the various grease fi ttings located in the cable drum, end bearing, clutch housing or
clutch operating linkage. Any good grade of moly-disulfi de containing grease is acceptable.
2. In the case of jaw clutch winches check the action of the sliding clutch, making sure it is fully en-
gaging and disengaging with the cable drum. Observe the jaws on both the clutch and cable
drum, checking for rounding of the driving faces. If rounding has occurred they should be
replaced immediately.
3. In the case•of Dow-Lok clutches,check the action of the locking ring. Make sure it is spring
loaded and free to move fully against the cable drum in the engaged position and that it is pulled
fully away from the cable drum and latched when disengaged.
4. Check the winch mounting bolts. If any are missing, replace them and securely tighten any
that are loose. Make sure to use only grade 5 bolts or better.
5. Check the torque setting of the oil cooled worm brake. Make any adjust ments required, following
the procedure described in ADJUSTING THE OIL COOLED WORM BRAKE in the Owner's
Manual.
6. Check alignment of chain and sprockets and adjust as required to minimize wear.
7. Inspect the cable. If the cable has become frayed with broken strands, replace immediately.
C. ANNUALLY
1. Drain the oil from the winch annually or more often if winch is used frequently.
2. Fill the winch to the oil level plug with clean kerosene. Run the winch a few minutes with no
load in the reel in direction. Drain the kerosene from the winch.
3. Refi ll the winch to the oil level plug with all purpose E.P. 140 gear oil.
4. Inspeet frame and surrounding structure for cracks or deformation.
5. Gear wear can be estimated by rocking the drum back and forth and if necessary drain oil and
remove cover for closer inspection.
