When aligning a misaligned coupling, which type of misalignment is usually corrected first?

In the process of aligning a misaligned coupling, it is essential to follow a systematic approach to achieve proper alignment and ensure optimal performance of the machinery. Vertical angular misalignment is typically corrected first because it often has the most significant impact on the coupling's overall operation.

Addressing this type of misalignment initially allows for a more effective correction of the angular relationship between the two shafts, which is crucial for reducing wear and tear on the coupling and preventing undue stress on the equipment. Once the angular misalignment is corrected, adjustments can then be made for both horizontal and vertical misalignments.

By prioritizing the vertical angular misalignment, technicians can ensure that the coupling will function more efficiently, leading to improved reliability and reduced maintenance issues in the long term. This methodical approach aids in optimizing the alignment process, ensuring that subsequent adjustments for horizontal and vertical misalignments are performed with less interference and more accurately.
