You may be able to find a kit on E-bay that replaces both cogs and the belt, and reduces speed for more torque. I just did that conversion on my Harbor Freight 7x10/12. That would maybe result in a more commonly available belt to boot.
Sk8ter,Thanks I have searched little machine shop and online...the belt is 1.5x100x9
seems no one has it
Yes thank youYou're welcome.
