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