Hello,
I recently purchased a used Jet JTAS10 table saw, and have noticed that the arbor binds up when raised to it higher height range. This happens whether or not the blade is installed. I can smell the hot rubber from the belts and do see a few sparks when making a cut, but when forcefully turning the blade by hand, I see no metal-to-metal points of contact. The shaft which gets turned for adjusting the blade height has some score marks and the arbor assembly becomes hot. Views from the top and bottom are limited and I am ready to remove the top to get a better view. Any suggestions before I take a deeper dive? The photos from above may not be helpful.
Thanks,
Steve
