WINCH ASSEMBLY

1. Place the motor adapter on workbench with the motor

mounting surface down. Install a new O-ring (21).

Lubricate the brake piston seal (16) with petroleum jelly

or hydraulic oil and install on the motor support with the

seal lip down, as shown above.

2. Insert a steel disc (20) into the motor adapter, followed

by a friction disc (19). Alternately install steel and fric-

tion discs until eight (8) friction discs and nine (9) steel

discs have been installed. Finish with a steel disc on

top.

NOTE: It is good practice to lubricate the discs in gear oil

prior to assembly.

3. Install the brake plate spacer (18) and the brake piston

(15) as shown.

4. Install the spring spacer (12) and the twelve (12)

springs (11) into the brake cylinder end plate (2).

5. While holding the motor adapter and brake assembly

together, turn it over and install into the brake cylinder

end plate. Install the eight (8) capscrews (38) and lock-

washers (39) but do not tighten them at this time.

6. Loosely attach the two tie plates (4) to the bearing sup-

port end plate using capscrews (4) and lockwashers

(43).
