RE-ASSEMBLY
1. Press brake hub into place over worm shaft and key.
2. Assemble balls in #2 slots of cam. Use stiff grease to hold balls into place and slide cam over end of worm. Be
sure that balls are secure, between cam slots and hub slots.
3. Install retainer plate, smooth side toward brake disc.
4. Install the gasket on the cover with a small amount of grease or sealer.
5. The coil spring goes over the adjusting screw on the inside of the cover.
6. Install the notches of the leaf spring on the pins protruding through the cover. The hollow side of the leaf spring
goes toward the brake.
7. Install brake housing cover, making sure the protruding pins go through the leaf spring and into the holes in the
retainer plate.
8. Bolt cover into place with the mounting screws. Install drain plug and add 3-3/4 pints all purpose E.P. 140 oil.
9. Turn winch in the hoisting direction at least one turn of the input shaft.
10. Turn the adjusting screw in until it is finger tight.
TEST FOR PROPER BRAKE ASSEMBLY
After the brake has been adjusted to the proper torque setting (see Adjustment section above), disengage clutch.
Start vehicle engine and run winch in the reel in (hoisting 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, run winch in the reverse direction (cable
out) for one minute. Brake housing should be hot to the touch.
When these conditions exist, proper installation has been made. If heating becomes noticeable when running the
winch in forward rotation (hoisting direction), the brake should be again disassembled. When disassembled, place
the brake balls in the alternate set of slots in the cam plates, then carefully follow the instructions for re-assembling
and checking the brake.
