WINCH MAINTENANCE
Adhering to the following maintenance schedule will keep your winch in top condition and per-
forming 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 oper-
ating condition so that hot oil gasses may escape.
3. Lubricate cable with light oil.
B. MONTHLY
1. Lubricate the various grease fittings located in the ends of cable drum shaft, end bearing,
clutch housing or clutch operating linkage. Any good grade of grease containing moly-
disulfide is acceptable.
2. In the case of jaw clutch winches, check the action of the sliding clutch, making sure it is
fully engaging 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 adjustments 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 immedi-
ately.
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. Refill the winch to the oil level plug with all purpose E.P. 140 gear oil.
4. Inspect 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.
WINCH MOUNTING
It is most important that this winch be mounted securely so that the three major sections (the
clutch housing end, the cable drum and the gear-housing end) are properly aligned.
All standard H-800 Dow-Lok ® series winches are furnished with recommended mounting
angles. Angle size is 1/2 x 3 x 4 high strength steel angle.
