Method 1 – Straight Edge Alignment for Standard Sleeve Type Coupler with Black Rubber Insert
(See Figure 7A)
Proceed with this method only if satisfied that face and outside diameters of the coupling halves are square and concentric with the coupling borers. If this condition does not exist or elastomeric couplings do not make this method convenient, use Method 2.
1.Check angular misalignment using a micrometer or caliper. Measure from the outside of one flange to the outside of the opposite flange at four points 90° apart.
DO NOT ROTATE COUPLER. Misalignment up to 1/64" per inch of coupler radius is permissible.
2.At four points 90° apart (DO NOT ROTATE COUPLER), measure the parallel coupler misalignment by laying a straight edge across one coupler half and measuring the gap between the straight edge and opposite coupler half. Up to a 1/64" gap is permissible.
