MAINTENANCE
Tulsa Rufnek series planetary winches, like any other piece of machinery, need to be
periodically serviced and well maintained to insure proper operation.
Good maintenance consists of four steps.
1. A daily inspection to insure that there are no oil leaks present, all mounting bolts and
other fasteners are tight, and that the wire rope is in good condition.
2. Changing the oil in both the gearbox and the brake section. (
Severity of use will
determine the need for oil changes but the oil should be checked at a minimum of every
500 hours. Factors such as extremely dirty conditions or widely varying temperature
changes may dictate even more frequent servicing).
3. Lubing drum bushings and sliding clutch with grease. The drum bushings are lubed thru
two grease zerks located on drum barrel.
4. Complete teardowns and component inspections. (
Again, severity and frequency of
use will determine how often this should be done).
If the equipment that this winch is
mounted to is subject to standards for this type of inspection, then those standards must
be followed. If oil changes reveal significant metallic particles then a teardown and
inspection must be made to determine the source of wear.
Rufnek series planetary winches are designed with a common oil reservoir for the gearbox
and brake. The winches are shipped from the factory filled with Mobilube SHC SAE 75W-
90 synthetic gear oil which is satisfactory for operation in ambient temperatures from -40°F
to +110°F. If winch will be operated in temperatures outside this range, contact Tulsa
Winch for recommendations.
The oil is drained by removing the drain plugs (86 & 81) located at bottom of gear housing
(60) & bottom of brake cover (2), then remove the fill plugs (74 & 81) located at the top of
the gear housing (60) & the top of the brake cover (2). Inspect the oil for signs of metallic
particles and/or burning and dispose of in a proper manner. Then re-install the drain plugs.
Fill the brake end with (1 pint) Mobilube SHC SAE 75W-90, then fill the gear end with (7
quarts) of Mobilube SHC SAE 75W-90 oil and replace both of the fill plugs.
OIL CAPACITY = 7 1/2 QUARTS
