Ramsey Winch H-930r DOW-LOK w/Air Shifter for Grant Wrecker - Manual (Page 6)

C. ANNUALLY
1. Drain the oil from the winch annually or more often if winch is used frequently.
· After draining, fill the winch to the oil level plug with clean kerosene.
· Run the winch a few seconds with no load in the “Reel In” direction.
· Drain the kerosene completely from the winch.
· Refill the winch with 10 1/4 pints all purpose SAE 140 EP gear oil.
2. Inspect frame and surrounding structure for cracks or deformation.
3. Gear wear can be estimated by rocking the drum back and forth and if necessary drain oil and remove cover for closer
inspection.
CABLE INSTALLATION
1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of cable, opposite hook, with plastic
or similar tape to prevent fraying.
2. Insert the end of cable, opposite hook end, under drum and into the hole in drum barrel. Secure cable to drum barrel, using
setscrew furnished with winch. TIGHTEN SETSCREW SECURELY.
3. Carefully run winch in the “reel-in” direction. Keeping tension on end of cable, spool all the cable onto drum, taking care to
form neatly wrapped layers.
The wire rope can easily be removed from the drum by loosening the setscrew.
ADJUSTING THE OIL COOLED WORM BRAKE
The oil cooled, fully adjustable, automatic worm brake operates in the worm housing lubricant, all parts being submerged in oil.
When the brake wears to the point that the load begins to drift, the brake can be adjusted as follows:
1. Loosen the adjusting screw lock nut.
2. Tighten the brake by turning the adjusting screw clockwise. CAUTION: Only 1/4 turn is usually required to adjust the brake.
Over-tightening can cause over-heating, and damage to the brake parts. Tighten the lock nut after adjustment is completed.
If the brake does not respond to adjustment then a new leaf spring and brake disc is needed.
A torque wrench can be equipped with a special adapter to fit the
input shaft (worm) of the winch. The adapter can be made by
welding a nut to the end of a piece of tubing as shown in the fol-
lowing figure.
After welding the cap and nut to the tubing, slot the tubing, as
shown. This will allow the special adapter to slide over the keyway
and will then act as a large socket. A torque wrench can then be
used to apply the proper torque. Turn the torque wrench so that
the drum turns in the spool out direction or lowering direction. The
torque rating for the brake on the Model H-930R Dow-Lok should
be 65 to 75 ft. lbs. If torque wrench does not show the proper
value as it turns, then the worm brake adjusting bolt should be
turned clockwise 1/4 turn. Each time the adjusting bolt is turned,
check the torque reading. Continue this procedure until the proper
torque reading is achieved. Then tighten the lock nut.
