So my belt snapped on my 50 cc sunl elite one day when i was at top speed (30 mph) and hit a bump in the road....took the cover off my cvt and the belt was in shreds...i got a new belt from napa....same size as the previous belt.....i borrowed an impact wrench from a friend and decided i would get to work on it.....well first of all i rounded the variator nut off which really ticked me off.....using the impact wrench properly and using the right size socket the nut was still such cheap metal it rounded right off.....so i removed the clutch and slipped the belt around the variator and then opened my clutch up and put the belt in that way....put it all back together and now when i start it im getting a chug chug chug sound and my accelerator does nothing at all.....also from what ive seen in diagrams and on youtube my belt is supposed to be either up on the variator and down on the clutch or visa versa and instead its down on both of them i believe...i have pictures but im not 100 percent sure on how to upload them but i will attempt to......it was running fine until this belt snapped and im sure its something ive done wrong somewhere along the way because im no expert by any means.....if anyone has any advice it would be much appreciated because this scooter is my only means of transportation at the moment....thanks guys

Well you will have to take the VARIATOR off, some of the weights probably CAME out fell out when you took the CVT over off. Also any weights in there are probably laying on there side and not in the ramps correctly. Standing still the belt should be down in the Variator and on top on the Clutch pulley: Alleyoop  |

As far as rounding off the Variator nut, I probably can guess what you did. You used a short socket and the socket did not go all the way on the nut. If you look at your impact wrench the square part that snaps into the socket is longer than a regualr socket wrench. So what happened is that part was protruding to far into the socket and now the socket was not all the way on the nut.

Then if you did you used the wrong size, I have taken off my variator and clutch more than you can shake a stick at and Its the same nut on both going on 5 years now. They have special sockets to use with impact wrenchs.
You have to push and keep it nice and striaght and then hit the switch and not constant a few quick raps.

really i used the right one....17mm i believe but dont quote me on it cause i dont remember right off hand.....but i know i had the right one.....but really its neither here nor there because in the end its stripped out like a *%&^#*........at this point the question is how would i get it off being rounded as bad as it is and being as tight as the variator nuts are? and from there do i put the belt on the shaft on the variator and close the clutch and put it on around the closed clutch instead of the closed variator or how should i go about that part

Use a nut splitter tool to get it off.

Use whats called a monkey wrench or pipe wrench and it will compress itself around the nut. Wedge a small open end wrench between the teeth of the gear and the inner variator housing.  |

If you mess up the gear teeth by wedging something in to hold it still, you won't be able to use your kick starter. Better to use a strap wrench to hold the assembly still while you use the monkey wrench to get the nut off, or use a nylon engine stop (cheaper).
