Tool Procedure
Feeler
gauges
1. Insert feeler gauges between the coupling faces at various points around the
circumference.
Do not rotate the shafts.
2. Reposition the equipment until the difference between the minimum and maximum
distance values is within the permissible range.
2. Check the parallel alignment:
a) Place a straight edge across the two hubs.
b) Measure the maximum offset at various points around the periphery of the hubs.
Do not rotate the shafts.
c) Reposition the equipment until the offset is within the permissible range.
See Maximum allowable misalignment for Rexnord Omega couplings.
A E10 coupling with a 3° angular misalignment will have a 0.191 in. (0.485 cm) difference
in measurements between L1 and L2. This is within the 0° to 4° misalignment that is
allowed for that size of coupling.
