Primary belt abnormal wear
I recently bought an Ultra Bee off of Alibaba through a company called Changzhou Proluxe Technology Co., Ltd. At the 207th mile marker I found my belt had torn through the backseat protective shield and the belt cover plastics. When I pulled the cover the belt was worn half away but only like the teeth of the belt were worn away. The outer part wasn't wearing. Also, the belt was EXTREMELY tight. The company said It was basically not a defect and that they wouldn't cover it. To me, this seems to be a misalignment. Now, I replaced the belt with a new one. Tried my best to align everything with a laser to make sure the jackshaft and the motor pulley is perfectly aligned. I checked the tightness of the belt and have it set to 13 mm of deflection midway between the pulleys. 80 miles later my belt is already wearing the same way the last one did. I can't afford to replace this belt every 200 miles! Can anyone help me where to go from here?
