torque driver mod

[stuckchuck]

so im getting a new Naruku T.D. within the week and have seen a few threads on mods, like shaving the top surface down to right before the top oil seal and elongating the slot in the td to get more travel in the pulley but this might be different. I want to take a port map of it in a sense wrap a piece of paper around it, flush and square on the ends. take a pencil mark out the new slot on it. and then transfer that to my old worn groove torque driver i am replacing.

This is the torque driver i'm getting. it has three different slots in the photo but product description says two?. so who was cut new paths in a t.d. ? any input will help greatly.

I plan on drill press to cut basic shape,use a bit just smaller then the slot im making stagger the holes end to end then a few hours hours with a dremmel and file/files to true it up and smooth edges? maybe extend some life to a otherwise worn out part?
a. i don't need to do this as im getting the new part shortly. B. is for balance if i do it right a slight balance issue might be there as its not cnc cut? javascript:add('%20:needpics:%20')

Any and all input is what im askin for and ill post it when and if it makes it into the burner so to say

You don't really need to map it out that way. Pretty much just get the angle(s) you would like to use and cut at that angle. Make the slots as long as they can be without interfering with seals. The grooves need to be as smooth as possible. Not like polished, but straight and smooth so the pins don't catch anywhere. The tough part will be making the grooves work together right by positioning them correctly. I've cut one just to show it, but never cut the second.

the grooves in your link is exactly what is was thinking and how i was contemplating it, i agree the 180* of exact rotation is key to getting it to work.

its a old part im trying on so its no real loss, and the original grooves are slightly wallerd out in it, still usable in a pinch but needs to be relpaced.I noticed it when the scooter began to engage the clutch early or not disengage and be stuck in a higher gear when slowing down then re-accelerating, and that came and went. i took the whole cvt apart to inspect it and saw the grooves were a little outa shape lol
