The wear mark(s) on top of your belt could be from rubbing against the starter bendix. I have those marks on probably 5 belts in my garage. It's basically one continuous line all the way around the belts. As long as the bushing(s?) the bendix sits into are ok, then I think it's just the way some of these engines are designed. Chinese scoots aren't perfect. See if the closest part of the bendix (to the belt) is directly above the line on the belt. Exactly. It is one continuous line all the way around. And yep, it sits right above where the line is. I was wondering if there was something i could do to fix this? Would this cause major belt damage over time - or just cause the minor line to a certain extent and doesn't get much worse from there? |

Atma, is the photo of the belt during installation or after you have run the scooter? This was as soon as I opened the case yesterday to document the belt wear. |

The back of the belt is hitting something within the belt housing. Are you sure you are using the right size belt? Too long a belt will let it flap around and strike something. Also, check the operation of the driven pulley. That belt isn't pulled down all the way into the center of the variator pulley like is should be. With a too large belt, it is possible the variator is open without the weights pushing it. Without tension, the ramp plate can have enough room to wiggle, which would destroy the guides. Funny you mention the belt being too long, that didn't really occur to me. Its a 1p39qmb, would that change the belt size at all, even by .1 somewhere? I've heard of 669-18.1-30, and so on. Also, would the system not adjust the belt into the correct position whilst moving? Or is that done manually, and i've been putting the belts on incorrectly all the while? That would makes sense, most likely elongating the belt, causing all the problems.. I'm purchasing a new variator and clutch pulley assemblies in the morning, i'm hoping this will fix any problems. The only things that aren't stock on this scoot are the carb, the CDI, and the belt. what better time to change that, eh? |

Hey guys. So, here's the thing. I put new guides on my variator about a week ago - Dr. Pulley. I imagined they would last forever, right? To my surprise, they have vanished. Obliterated completely, only to leave bruised metal in it's wake. The stock ones I had on there were coming apart at the seems, literally, though they ended up lasting 3k km. I would imagine that the new, beautiful Dr. Pulley ones would at least double that mileage, but not at all. There must be something wrong somewhere in the CVT, yes? Also, on the belt, (which this is the third one...first two cheap chinese, this one's kevlar) there happens to be this line of wear that appears. I figured it was because of the horrible guides i had previously, letting everything knock around too much, so I flipped the belt after the guide change to see if the line would still appear. It has. Since the new guides have gone MIA, the belt wear could still be caused by the moving and shaking of the guideless variator, yes? I did, however, find one tiny remainder of one of the guides, in the bottom of the CVT cover. Anyone know what could be going on? I'm ordering a new variator tonight, definitely- but could it be clutch related? The spring seems fine, the clutch shoes are decent, no misshape on the clutch bell, etc. Something i'm missing? I'll attach some photos. Image of the wear  Damage near the weights  Hope everyone is having a nice day so far, by the way. |

Namaste, and Hello, everyone! I've been lurking these boards (this and scootdawg) for a couple of months, and i'm finally deciding to create an account.
Name's Kaius, though Atma fits. I own a 50cc TaoTao scooter, black, as you can see from my picture. You guys have helped me out over the course of the last few months without even knowing it, ha. You and youtube have turned me into my own mechanic with this little guy, and I really appreciate it.
I'm living in South Carolina. I work retail to pay the bills and teach Yoga here and there as a passion. The climate is great out here most of the time for scooting, and that's great because its my only form of transportation for the moment!
I've been having fun replacing things on it so far. Carburetor, roller weights, belts; its all good fun. I've always had a four wheel understanding, working on my old SUV and my buddy's Corolla and such, but with this 4 stroke i'm learning a lot. Hopefully a lot of this knowledge will transfer over when i'm able to obtain a motorcycle at some point.
Anyway, i'm here, and I hope to get cozy.
Here's to many miles. (:
