6-7.3 Adjustment of the Brake:
a.
The torque required to turn the winch input shaft, in the lowering direction against the worm brake, should be 40
to 45 foot lbs. If a 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 on the input
shaft. Continue this procedure until the proper torque reading is achieved. Then tighten the lock nut.
b.
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 in figure 6-3.
