chinese 50cc moped

I removed my variator to derestrict the slider but forgot to put shims in. Now the variator nut is too tight and it spins but doesn’t come loose and the fan plate also wobbles about.

This is going to be expensive or at the very least a lot of work.
The crankshaft needs to be replaced.

Are you sure the threading isn't other way around?
