alignment at assembly. The only component requir-
ing regular inspection or servicing is the coupling
flexible element, which may be accessed as fol-
lows:
Disconnect all power at source before attempting
maintenance or adjustments. Follow lockout pro-
cedures (See Safety Section).
INSPECTION/REMOVAL OF FLEXIBLE ELE-
MENT
1. Loosen fasteners securing wireform guard to the
distance piece and remove to allow access to
the coupling assembly.
2. Loosen and remove all capscrews securing each
flexible element half to the shaft hubs.
3. Inspect each element body for signs of tears or
separation away from the metal flanges - if any
faults are found, elements must be replaced and
Sullair contacted for further assistance.
4. Reassemble in reverse order. Capscrews must
be re-torqued to 39 ft.-lbs. (53 Nm) (dry). Please
note that capscrews have self-locking patches
good for two re-uses, but the application of a
thread-locking adhesive increases this number.
DO NOT lubricate capscrew threads.
Please note that replacement of either shaft hub
requires the removal of the motor, an operation best
handled by Sullair personnel.
