Can we talk about the weird vibration I felt on the cutter head last Friday?
Working on a sand reclamation job near Mobile. Felt a high frequency hum through the deck plates around 3 PM. Not the usual shake. Checked the suction pressure gauge, it was jumping between 85 and 110 psi real fast. Shut it down and found a chunk of old timber wedged between two cutter teeth. Thing was petrified. Anyone else had a weird vibration turn out to be something simple like that? How did you spot it?

That pressure gauge jump is a dead giveaway. I always watch for that needle dance more than the vibration itself.

Honestly, @emma_rodriguez30 is spot on about watching the needle. Read an old service manual that called it the "tattle-tale" for a reason. Saw it happen just last week on a unit where the vibration felt normal, but that gauge was jumping like crazy. Ended up being a worn piston in the compressor. Tbh, you can feel a lot of things, but that needle doesn't lie.

Ever notice how a steady vibration can feel fine but that gauge jump points right to a specific issue? I had a unit last month with a real jittery needle on the low side, but the high side looked rock solid. Traced it back to a failing expansion valve starving the evaporator. The vibration was there, but the gauge told the whole story. What's the weirdest problem you've caught just from watching the gauges?
