explained in Reassemble Check Valves, page 32.
NOTICE
After reassembly, allow the thread locker to cure for
12 hours, or per instructions of the manufacturer,
prior to operating the equipment. The equipment will
be damaged if the diaphragm shaft fastener loosens.
Apply a high-strength thread locker to attach the
fastener to the diaphragm plate.
Apply a medium-strength thread locker to the shaft
side of the fastener to attach the diaphragm to the
shaft.
