23. Lubricate the brake cylinder o-ring and install it over
the brake cylinder. Push it all the way against the
motor end plate.
24. Install the motor adapter over the brake cylinder
using the
SPECIAL
BRADEN capscrews and wash-
ers. Torque to 110 lb-ft (150 N-m).
25. Attach the tie plates to the end plates. Locate the
curved edge toward the top of the hoist. Secure the
tie plates using the
SPECIAL
shoulder bolts and
washers, and torque to 110 lb-ft (150 N-m).
26. Install the tee fitting and hose to the brake release
pipe nipple. Use a good grade of thread sealant or
sealing tape on the threads. The hose will be
installed toward the LH side of the hoist assembly.
27. Lubricate the motor o-ring, and install it over the
motor pilot.
DO NOT
use standard capscrews to install the tie
plates. The
SPECIAL
shoulder bolts are used as
locating dowels for the hoist assembly. Use of stan-
dard fasteners can lead to looseness in the hoist,
possibly resulting in excessive wear and heat gener-
ation inside the hoist.
CAUTION
DO NOT
use standard capscrews to secure the
motor adapter to the end plate.
The capscrews used to secure the motor adapter to
the end plate are of
SPECIAL
design, and
MUST
be
used. Using standard capscrews to mount the motor
adapter can result in joint failure that can allow the
motor shaft to come uncoupled from the brake clutch
and gear train. Failure of this type can result in loss
of load control which can result in property damage,
severe injury or death.
