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 and that 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 it 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 thru grease fittings located on 

drum barrel and clutch. 

 
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 (31 & 94) located at bottom of gear cover 
(3) and bottom of brake cover (18).  Then remove the fill plugs (39 & 94) located at the 
top of the gear cover (3) and the top of the brake cover (18). 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 Mobilube SHC SAE 75W-90 (1/2 quart), then fill the gear end 
with Mobilube SHC SAE 75W-90 oil (19 quarts) and replace both of the fill plugs.
