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 completed.
If the brake does not respond to adjustment, then a new flat spring (item #3) and/or brake discs (item
#32) 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" dia. 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.
