Remove the wire ring from the coupling sleeve and let it hang between the sleeve and one of the flanges.

Place a straight edge across the two coupling flanges.

Measure the maximum offset at various points around the periphery of the coupling without rotating the coupling.

Is the maximum offset within the acceptable range as per the 'Parallel' table?

Measure from the outside of one flange to the outside of the other ('Y') at intervals around the periphery of the coupling using a micrometer or caliper.

Determine the maximum and minimum dimensions without rotating the coupling.
