I recently decided to put tune up my bandsaw that I have not used in a couple of years. It is an old craftsman. When putting on the new blade I noticed the top wheel(tire?) is loose and whenever I started to tighten the blade it would begin to tilt. I would hand turn to see if the blade was aligned and it would run off the front of the tire. I could not find any way to tighten this. Any comments or help would be appreciated. I may have left the old blade on with some tension
