Please be carefully check the goods appearance, size, shape before ordering. How to Select the correct belt? 1. Determine the series type. 2. Measure the ”Outer Diameter” (O.D.) of the driven pulley on the jack shaft. 3. Measure the ”Center Distance” (C.D.), which is the exact distance between the center of the engine crankshaft and the center of the jack shaft, must be precise. 4.

Friendly tips Belts are rubber products. As the working time increases, the transmission belts are prone to wear or aging.

  • Wrong Size.
Item Package Quantity: 3
Did not fit properly to my GY6 qmb 139 motor chinese moped. Joc 50 with BBK. Disappointed as this was the umpteenth time I've purchased parts for moped and I'm getting tired of false advertising/not clear and misleading sizing. I assume has to somewhat do with a language barrier. really selling out of country- you need to know their language- tranlate correctly and provide a clear objective for your product and it's future purchaser. Just saying. Can't tell you how the build actually is or how long it lasts as it did not fit. ... show more
