12. Install the brake cylinder assembly over the primary
sun gear, making certain the brake cylinder engages
the ring gear adapter teeth.
13. Install the brake clutch assembly over the primary sun
gear. When installed correctly, the outer race should
turn freely in the same direction as the drum turns to
spool wire rope out. For most Braden assemblies, this
will be clockwise as viewed from the motor end.
14. Before installing the brake discs and friction discs,
check their condition. Both kinds of discs should be
flat and their teeth should not be pointed. The friction
discs should have groove in the friction material.
Replace discs, if necessary.
15. Install the brake discs. Start with a brake disc and end
with a brake disc. Alternate brake and friction discs
until there are nine (9) of the friction discs and ten (10)
of the brake discs.
16. Install the brake plate spacer on top of the brake discs.
17. Measure the brake stack-up as shown. The measure-
ment should be a minimum of 3/16" from the top of the
brake plate spacer to the top of the brake cylinder. If
the measurement is less than 3/16", remove the brake
plate spacer and add a brake disc to the top of the
brake package. Replace the brake plate spacer and
repeat procedure. Do not exceed an overall height of
¼".
