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 30 ft.-lbs. (40.7Nm) (dry).
Please note that capscrews have self-locking
patches good for two re-uses, but the applica-
tion of a thread-locking adhesive increases this
number.
Please note that replacement of either shaft hub
requires the removal of the motor, an operation best
handled by Sullair personnel.
