Guest Post by Bob Dunn from I&E Central, Inc.

I had the opportunity use the Easy-Laser XT440 to assist a customer aligning a machine that had perpetually given them problems, with bearings always running hot. They had recently aligned the machine with dial indicators, but when we checked, it was off by .007, and this on a 3600 RPM motor. We removed their old shims and did a soft foot check indicating .032 under one of the feet. Further inspection showed an angular gap under one foot. It turns out that when new, someone had ground down the feet on the motor to better align to the pump – obviously not a precision job. We step-shimmed to fill the angular gap, then aligned the machine in a single move. Several of the techniques we used were unfamiliar to these mechanics.


  1. Do your pre-alignment homework to detect and correct foundation issues.
  2. Be sure mechanics are really trained in alignment – not just how to push the buttons. By the way, Ludeca Inc. and I&E Central provide excellent training.
  3. The Easy-Laser XT-Series is a fast, accurate, and incredibly easy-to-use tool for coupling alignment and more. If you use something else, you should see what you are missing!
