My brother that lives far, far away has a scooter for disabled to ride. I don't know if it is 3 or 4 wheeled. There is nothing on the scooter that gives a slight hint who mfg. it or where it came from. Anyway, a tooth broke off the drive belt and he is trying to buy a new one and we can't seem to find one. The belt is 18" in circumference. The number on the belt is 180XL037 made by Goodyear. The only place on the computer that I can find that number is in a Kirk Rudy site, but I can't order from that site. Kirk Rudy cross reference's it to # 109015. That cross reference's to Goodyear lawnmower belt 83270. Maybe some of you computer guys can find something. Thanks.
