ADJUSTING THE OIL COOLED WORM BRAKE

The oil-cooled, fully adjustable, automatic 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 lock nut on the adjusting screw.
2. Tighten the brake by turning the adjusting screw clockwise. CAUTION:

Only ¼ turn is usually required to adjust the brake. Over-tightening can
cause overheating, 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 below.
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 Model HDG-350 should be 9 to 15 ft. lbs.
If the torque wrench does not show the proper value as it turns, then the worm
brake adjusting bolt should be turned clockwise ¼ turn to increase the torque
setting. Each time the adjusting bolt is turned, check the torque reading. Con-

tinue this procedure until the proper torque reading is achieved. Then tighten
the lock nut.
