Carefully inspect both halves of the metal face seal be-
tween the motor support/brake cylinder and the ring gear.
If the metal contact faces show signs of excessive wear
or mechanical damage, or the rubber rings are brittle or
damaged, the seal should be replaced.
ASSEMBLY
1. Set the motor support/brake cylinder on a bench with
the motor end down.
2. Starting with a steel disc, alternately install a steel then
a friction disc until nine of each type disc have been
installed (ending with a friction disc). It is advisable to
lightly lubricate the brake discs with oil that will be used
in the winch prior to assembly.
3. Install the spacer plate (Item 82) on top of the last fric-
tion disc.
4. Install the retaining ring (Item 81). Turn the assembly
over with the motor end up and be sure all brake plates
are stacked squarely against the spacer plate.
5. Install new O-rings and backup rings (Items 86 and 87,
88 and 89) into the brake cylinder as shown. It is VERY
important to position the O-rings and backup rings as
shown above to prevent brake cylinder leakage.
6. Lightly lubricate the sealing surfaces of the brake pis-
ton (Item 90) and install it into the brake cylinder until it
touches the brake discs.
