My Fix for my Failed Shim Mod
« on: July 20, 2016, 12:56:41 AM »
Even though I believe my shim mod was sound and only failed due to the nut backing off, I still didn't want to take a chance on it again. But, I can't afford to get my primary machined or right now even sliders. I also want some low gearing for my kind of riding. I came up with a fix that I hope will be stronger than stock, but I still got even lower gearing than with the shim. Here's what I did.

My old cam plate didn't strip completely. It backed off and sheared the splines from the inside half, all the way around. But the splines still remained on the outside half. I cut the center out and ground the side with splines flat and smooth. Then I ground the other side all the way down to the splines and down to 1mm thickness. I ground it as round as I could. I lined up the splines with the splines on my new cam plate and welded it in. I tried to make sure it was as smooth and well balanced as possible. I thin put the CVT back together. This did the same job as the shim, but with more splines to mesh instead of less. I got even lower gearing this time, about 3.4:1.

Here is a pick of the shim.

Sorry, I didn't get anymore pics. Once I get started on something, I usually don't stop until I'm done. I usually don't take time for pics.

Thanks guys. I rode down the road to my parents house this evening. It seems OK. I used a torque wrench and lock tight this time. If I didn't screw anything else up, it should be good. The clearance is tight between the belt and case, but it has a little space. It will get closer with wear. I'll have to check it from time to time.

Hope it works out for you.  Like i said with your previous post i have never seen a shim be a good long term solution but then again i have never seen anyone weld the shim on the plate either so who knows.   Keep us posted on how you come out on it.
I can imagine a world completely at peace.  A world where there are no weapons, no war, and no violence at all.  And I can imagine us taking over that world because they would never expect it.

Sure thing. If it isn't storming, I'm going for a ride tomorrow. I don't see a problem with my design, but it's possible I could have screwed something up. I'll keep my fingers crossed and hope for the best.

Took a ride a couple of weeks ago. I ripped up some mud holes and slung some gravels. So far, it's holding up good.

I think with it welded to it you should be fine.  It COULD strip it over the long haul but it would likely be from abuse/putting the machine where it shouldnt be and not using your head to get it out.  Im not saying you will do that im just saying it looks like a strong fix and normal use of the machine I would think it will hold up ok.

I like to play a little, like I said, ripping up mud and slinging gravel. But, I'm not nearly as rough on it as a lot of people. I do know throttle control and rarely go WOT.
