    I think if you contact whirlwind propellers, they are the distributor for the circle-s redrive. you might find an answer to your question.

    The belt is a GATES POLY CHAIN GT #8MGT-720-36 ...720MM / 28.35 INCH, 90 TEETH... Use that item number then pull up the specs from Gates if you need more specs...Those backside ribs are what gives that distinct sound from the idler when running....Here's an ebay auction for one.... https://www.ebay.com/itm/GATES-POLY-...1USB-4&vxp=mtr

    I'm going to move this into the Reduction Drive forum for future readers to access the belt info
