I went on to the APP site and looked for reports of a similar problem. I verified that the cam was bad and then I watched a UTube video on how to replace the cam. It was a simple repair. I also got a new drive belt, which is much tighter than the one I removed. It seems as though it might be a little too tight but we'll see how it goes. It may stretch a bit and reduce the side load on the bearings. It was an easy fix that took about 15 Mins.
