pling alignment should be checked. For reference
only, the allowable angular and parallel shaft mis-

The only component requiring regular inspection or
servicing is the coupling's flexible element, which
may be accessed as follows:
DANGER
!
Disconnect all power at source before attempting
maintenance or adjustments.
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 bolts 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.
Table 1 and Figure 7--12.
MAINTENANCE
4. Re--assemble in reverse order. Bolts must be re--
torqued to 30 ft.--lbs. (41 Nm) (dry). Please note
that bolts have self--locking patches good for two
re--uses, but the application of a thread--locking
adhesive increases this number. DO NOT LU-
BRICATE BOLT THREADS!
Please note that replacement of either shaft hub re-
quires the removal of the motor, an operation best
handled by Sullair personnel.
