To disassemble, remove both screws and
reinsert one screw in the vacant hole (threads
on bushing). Tighten this screw until the
bushing is loosened in the hub. If the bushing
does not loosen, tap on the hub. Go to Step 3.
Installing The Torque Arm
Step 3:
The maximum length threaded rod is furnished
for normal mounting. (Consult the factory for
recommendations on a longer arm.) The
threaded rod can be cut to any desired length.
One rod end must be secured to the tab on the
Electrically Released Brake and the other end
must be secured to a solid base. Although the
torque arm may be mounted in either direction,
the position of the tab and arm is important.
Recommended position relative to shaft rotation
is shown in Figure 4. On reversing applications
where the rod is in compression every other
cycle, the rod must be relatively short, or a
special heavier rod may be necessary.

Do not connect rigid conduit
directly to the conduit box. A minimum of 12”
of flexible liquid tight conduit or other suitable
flexible wiring with appropriate fittings is
required. Flexible wiring is required to prevent
side loading of bearing on bearing mounted
clutches and possible deformation or breakage
of the conduit box or clutch/brake components
during assembly.
