ADJUSTING THE BRAKE
All parts of the oil-cooled automatic safety brake are bathed 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 (see drawing on Page 10).
2. Increase the brake torque 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 com-
pleted.
If the brake does not respond to adjustment, then a new flat spring (item #3) and/or brake discs (item #31) may be needed.
Brake torque can be checked/set as follows: A torque wrench can be equipped with a special adapter to fit the input coupling of
the winch. The adapter can be made by welding a 1" diameter straight motor shaft, with 1/4" key, in a 1" hex socket as shown
in the following figure.
This special adapter will fit into the motor shaft coupling. Place coupling onto drum shaft in winch. Turn the torque wrench so
that the drum turns in the "CABLE OUT" direction (lowering direction). The torque setting for the brake should be 155 to 160 ft-
lbs. If the torque wrench does not show the proper torque value, the adjusting screw should be adjusted 1/4 turn (clockwise if
torque is low or counter-clockwise if torque is high). 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. If proper adjustment cannot be made,
follow overhaul instructions on Page 10.
After the brake has been adjusted to the proper torque setting, as described above, disengage clutch. Start vehicle engine and
run winch in the "CABLE IN" (raise direction). Allow winch to run in this direction for one minute.
Place your hand on the brake housing. If housing is not hot to the touch then run winch in the reverse direction (cable out) for
one minute. Brake housing should begin to heat.
When these conditions exist, proper installation has been made.
