4. Once the fluid covers are removed, the
diaphragm on the side of the pump which was
last pressurized with air will be separated from
the center section/air cover. This allows you to
grip the diaphragms.
5. To loosen, grip both diaphragms securely around
the outer edge and rotate counterclockwise. One
diaphragm assembly will come free and the other
will remain attached to the shaft. Remove the
freed diaphragm (10), screw (14) if it remains in
the shaft, and air side plate (9).
