I'm having an issue with my CVT system and I'd thought I'd throw it out there to find a solution.


Here is a history of what's going on:

I current belt is 46 1/4 and 1.23 inches it's an old belt and I assume it was originally 1.25. I ordered a Dayco HPX 5001 belt as it fit the specs and was a High performance belt. I put it on the machine and ran it for a couple minutes and turned the machine off and found this:



So I checked my old belt and it matched the size. The tension is not that tight. I installed the belt without much difficulty by walking it over the driven.
The only issue I have with the old belt is an oscillation at about 3/4 power:






I'm at a loss and don't want to replace the replacement until I figure it out. I do have a custom engine mount that may need adjusting.

Any insights or suggestions would be much appreciated.

Thanks

Mike
