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.
