2008 Buddy Pamplona 150, 14k miles.
Playing around with roller weights, found belt was worn and cracking. Ordered new one from Scooterworks. They sent (as ordered) 742x20x30. Manual says this is right (for 125).
Putting it on I noticed it was a little wider than the old one. Reinstalling variator, everything seemed extra snug. Secured the nut (super tight (I thought)), lit it up, turned up the throttle, whole variator assembly spun itself off. Everything went flying.
I compared the old belt to the new. Old (stock) says 742x20x28. New is 742 x 20 x 30. I assume first number is length around (OD?), second is external width (18 on old, 19.5 on new). What is the third number? Could that be why everything spun out?
Now I've gotta get a new variator, etc because I'll never find all the parts all over the parking lot.
Thoughts?
