Best guess is 3.5" diameter. Belt number is 34-669. It is pretty stretched and burnt so measurements will not be accurate. Please let me know if you find it, I am down till I find another. Jimi
Jimi, just went online and it said that for Rockwell table saw parts to contact Delta..I am thinking that perhaps Delta may have your table saw belt online. Let me know. Joyce PS: need to know the circumference of that old belt and I'll bet you can get it from Delta.
