Everything seems to be working, I'm not getting anything below 65, but on a 100 degree day I don't even care, it's better than what I had before. So thanks for your input guys.
Like RichardJ says, you are going to take out some bearings with that kind of belt tension. More attention is needed to get to the root cause of the issue.
