6-3. 1 The oil-cooled, fully adjustable, automatic safety brake operates in the worm gear 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:
a.
Loosen the lock nut on the adjusting screw.
b.
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. If the brake requires
more tightening than 1/4 turn, a torque wrench should be used to check the proper torque, at the worm each time
the adjusting screw is turned. Refer to paragraph 6-7. 3 ADJUSTMENT OF THE BRAKE. Tighten the lock nut
after adjustment is completed.
6-3. 2 If the brake does not respond to adjustment, a new leaf spring and brake disc are needed. After installing new
part, see paragraph 6-7. 3 ADJUSTMENT OF THE BRAKE.
6-4 ATTACHING WIRE ROPE TO THE DRUM
6-4. 1 General. The winch has two tapered pockets cast into the drum. One pocket is for installations with the wire rope
wound over the drum. The other pocket is for an under-wound wire rope. When properly used, the wedge pocket design
is one of the most secure anchoring methods available.
