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 fi t 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 follow-
ing fi gure. 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 200/246 should be 8 to
13 ft. lbs. (D-200, 13 to 18 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 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.

SERVICING OF THE OIL COOLED SAFETY BRAKE

1. Remove the drain plug and drain the worm gear oil from the worm housing.
2. Back off the lock nut, then the adjusting screw, both two turns or more by turning them
counter-clockwise.
3. Remove the cover mounting screws.
4. Remove the cover along with coil spring and leaf spring.
5. Remove the retainer plate, composition brake disc, cam plate and balls.

Note, the slots the balls are in.

6. Inspect parts as follows:
a). Composition brake discs are 1/8” thick when new. Replace if thinner than 0.080” or if

surfaces are glazed or burnt.

b). Inspect the fl at, ground surface of the cam plate and retainer plate for glazing, warpage, or

other damage. Glazing can be removed by scraping carefully.

c). Inspect the leaf spring. It should be bowed 1/8”.

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 overheating and damage to the

brake parts. Tighten the lock nut after adjustment is completed.
