Variator/Belt Issue?

[sccruzean]

Hello All,

I had a bit of "chatter" coming from the belt area so I decided to investigate and found that the variator nut was loose. I thought that it might be a good idea to put some lock tight on the threads and took the nut off. As I did that, the variator popped off and the belt fell off.

No big deal...

Well after an hour of trying to put everything back with no success I decided to look for help here and learned that you have to compress the clutch make it all fit.

Once back together I took it for a ride and now when I am starting out the whole thing shudders and shakes and feels like it is going to die. The interesting thing is that once it gets up to about 20mph it seems to smooth out and run much better.

I am at wits end, any help would be appreciated.

Thanks,

Chris

Not sure I'm understanding your terms. The pulley on the engine is the variator. The driven pulley at the back is the clutch. How many miles on your scoot. The rear pulley,(clutch) requires a thin film of grease on its internals. There are u-tube videos that demonstrate disassembling these. That might help you get going in the right direction. The thing shouldn't shake like you said.
Good luck
Chris

Had simular problem on my 260. When your variator face fell off did you notce the condition of the Aluminum spline in the variator and the crank? The variator fan face spline is probably worn badly and needing to be replaced. When you put the bolt on the face face may still be slipping on the crank spline.
The belt is a another main issue when putting the variator fan face back on, and you really need the belt loose so the fan face can be torqued on the shaft.
Max - keep us informed and good luck

You need to completely remove the variator, clean it and verify that all the rollers are correctly oriented and back in place. You may have on turned sideways. This is very common and can cause a lot of vibration.

rockynv is right, but remember when putting the variator back on you can have the rollers come out of place, so you need to put back together, put your screws in, hold together from the work brench to where it slides on tight as you slide the shaft back through the variator.

Rockynv is right on this, I should have added it in my message, Mine on the new variator were
out of sink and I took it apart and found it was the rollers not in propper place
