One question that arises regularly in training is about doing alignment checks. Is it okay to just check the alignment? Of course, it is. As a matter of fact, many industries have dedicated crews to specifically do alignment checks. The major difference is no equipment is moved, just measured. We lockout, remove guards, install the laser, measure and record the data.
There a few reasons for alignment checks.
Even when we are going to perform an alignment on a piece of equipment, it is a good practice to record a pre-alignment measurement to document or maybe explain any possible issues later. Data is good. Once misalignment is discovered or verified. It should be corrected. If not immediately, then scheduled very soon after to eliminate the detrimental effects on the machine.
Be sure to follow the COMPLETE procedure of precision shaft alignment from the beginning. I recommend against quick shim adjustments or moves. If I am doing the job, I will remove and discard the shims and begin cleaning, etc… Follow the pre-alignment steps as prescribed by VibrAlign for successful results.
