Frustrating is about as accurate of a term as I can think.

Before I removed the top I was less than .007 off. After I removed it I found that the middle belt was not tight and so I ordered new belts and bought and installed new bearings.

After reassembly, I notice that the center belt is still not as tight as the others. I've tried to swap them around and it's the same outcome. If I run it for more than 30 seconds the belts get hot! I checked the pulley alignment and its good. Surely that's not normal? Could the arbor be bent? My HF dial indicator and magnetic basr is all over the place but I don't trust it as a quality tool to justify a new arbor

Lastly if I only put in 2 bolts I can get it close but the third is off enough that I would have to grind the hole larger. I would be OK with this except I know it was very close before.

All help is appreciated!!
