After countless adjustments, nailed the laser alignment on that temperamental gearbox today.

It's been a headache for ages, but seeing it run smooth is so satisfying. My foreman even gave a nod of approval, lol.

Honestly, laser alignment can be overkill for some gearboxes. We had a similar issue at a plant last year, and it turned out the foundation was shifting, so no amount of alignment held. Sometimes you gotta look at the bigger picture, like mounting surfaces or wear patterns. Seeing it run smooth is great, but if the root cause isn't fixed, it'll be back in a month. Just my two cents from dealing with vibrating pumps all day.

Examine the foundation before even pulling out the alignment tools. What specific indicators do you look for when suspecting foundation problems, like hairline cracks or uneven wear on mounting bolts? In my experience, skipping the basic checks leads to repeated failures, and it's frustrating to see the same issues recur. Have you found any reliable methods to monitor foundation stability over time, especially in older plants? It seems like a cultural problem in maintenance where we rush to fix symptoms instead of diagnosing the system.

My buddy had a similar thing with a conveyor motor last spring, where they kept realigning it but the vibration kept coming back. Turns out the concrete pad had cracked and was settling unevenly, so like @riley_miller25 said, the root cause was totally missed. They ended up having to pour a new foundation section before any alignment would stick. I mean, it's crazy how often we jump to tweaking without checking the basics, idk.

Given @wrenbrown's example, how do you balance the urgency to fix immediate alignment issues with thorough foundation inspections? Is there a checklist or protocol you follow to avoid missing these root causes?
