NOTICE:
• Do not rotate the coupler to make adjustments. This may result in equipment damage.
• Do not move or shim the driver unless you need to make adjustments. This may result
in decreased performance.
Make sure you have the following before you start this procedure:
• A micrometer or a caliper
• A maximum 1/64 in. (0.397 mm) end clearance between the sleeve and the two
coupling halves
1. Check for angular misalignment:
a) Measure from the outside face of one flange to the outside face of the opposite
flange at four points 90° apart. Use the micrometer or the caliper.
The maximum permitted mis-alignment value is 1/64 in. (0.397 mm) per inch of the
coupling hub radius.
1. Distances Across Coupling Flanges Should Be Equal (check 4 places)
Figure 3: Example of angular misalignment
b) Move or shim the drive unit, if necessary, until the permitted reading value is
obtained.
2. Check for parallel misalignment:
a) Put a straight edge across one coupling half.
b) Measure the gap between the straight edge and the opposite coupling half. Use
the micrometer or the caliper.
A gap of maximum 1/64 in. (0.397 mm) is permitted.
