I counted the gears. I have a counter gear set adding another ratio to the mix.
My clutch drive shaft has a 15 tooth gear on it and that drives the counter shaft gear of 42 tooth. the small gear on the counter shaft is 17 tooth and that drives the final gear of 36 tooth. Not real sure how to add/multiply/divide to get final ratio. Having all of that information where do I get gear sets? I usually buy from bladepowersports.com or partsforscooters.com and I do not see that either carry the type of gears in my buggy. Should I be replacing the final gear sets or the chain spocket gears?
Last question, Tom says to freeze the gear behind the variator, why? That gear is a press fit on a beveled shaft, freezing the gear whould cause the gear to shrink making it harder to press onto the shaft. From a mechanical press fit application shouldn't I freeze the shaft (shrinking it) and heat the gear (expanding it) so the two slip together?
