ADJUSTING THE OIL COOLED WORM BRAKE

The oil-cooled, fully adjustable, automatic safety 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 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 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 following
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 13ft.
lbs. (D-200, 13 to 18ft. lbs.).

If the torque wrench does not show the proper value as it turns the worm brake adjusting bolt
should be turned clockwise 1/4 turn. Each time the adjusting bolt is turned, check the torque read-
ing. Continue this procedure until the proper torque reading is achieved. Then tighten the lock
nut.

If the torque wrench does not show the proper value as it turns the worm brake adjusting bolt
should be turned clockwise 1/4 turn. Each time the adjusting bolt is turned, check the torque read-
ing. Continue this procedure until the proper torque reading is achieved. Then tighten the lock
nut.
