Title: Roller Direction in Variator
Post by: Vision on June 09, 2023, 12:31:33 AM
It's strange that this information isn't listed anywhere, not even in the manual. The best I can come up with is the roller side with the more composite material should be on the right side which is facing the V. 

This information comes from a comment from a youtube video. The person making the comment is contradicting the video creator and who says it should be facing the left. The commentator suggesting the right says he spoke with the Kymco factory.

Years of experience with these things shows that it really doesn't matter.  They're not actually "rollers" - they slide to and fro without rolling. That's why some are actually asymmetric in shape and they're called "sliders".  Or even "sliding rollers"! Performance may vary slightly, but you can always try them a different way. I grease the roller/sliders with a touch of lithium grease. Feel free to experiment.

Agreed to roller points, no difference how you put it.

For greasing: made the experience (in dusty ambiance) roller which were lightly greased had more wear due to collected muck.

I would only greasy the ones which are covered by a plate (some models) or according to factory standarts.
 Saw, when CVTs innert ramps were nicely polished, less wear on ramps and rollers.

Yes, when there's a difference - the metal side of the roller goes to the right when dropping in at 12 o'clock.

Well I put them in with the metal side on the left per the youtube comment. Is this a problem?

No.
Just next time try them to the right.
This is per Robot, the Vespa guru.
