(3-3/4 pints of S. A. E. 140. )6-7.3 AdjustmentoftheBrake:a.The torque required to turn the winch input shaft, in the lowering direction against the worm brake, should be 40to 45 foot lbs. If a torque wrench does not show the proper value as it turns, then the worm brake adjusting boltshould be turned clockwise 1/4 turn. Each time the adjusting bolt is turned, check the torque reading on the inputshaft. 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.
