I have a Delta 20" Bandsaw Model 28-641. I am unable to turn the tension wheel. If you look at my youtube below you can see this problem. Oddly on the phone Delta said it was broken and another shop guy I emailed said it appeared the unit was taken apart and reassembled incorrectly. However in the exploded view it looks fine. Also look at images.
I am a shop/technology teacher and received this used unit from my supervisor as it was going up for auction due to closing a shop but the previous teacher is retired and moved away.
My youtube link which you can see trying to turn the tension wheel:
