One of the many things I love about my job is the numerous challenges we face during the field alignment portion of our Precision Shaft Alignment Training.

Prior to the training, there were some repeatability issues when attempting to perform a precision alignment on this piece of equipment. One of the main causes of non-repeatability is soft foot.

During the pre-alignment steps a couple of things were noted that could contribute to this situation.

  1. The shims were not the correct size, they were “B” size and should have been “A”.
  2. They were not clean.
  3. They mic’d out different thickness than what they were labeled.
  4. The spacer plates were rusted, corroded and uneven.

After making the corrections to these items and completing all the pre-alignment steps, the alignment took about 20 minutes and total alignment time from start to finish was just over 40 minutes.

The results? A precision shaft alignment meeting 3600 rpm tolerances on an 1800 rpm motor.
