Chuck, thanks so much for the explanation. I have disassembled one and I thought that was the way it worked. Thanks for confirming that. The bad one did not act any different from the new one so I a bit puzzled as to why. But replacing it I have not had any problems for over a week now.

I probably need to check the pucks and most likely replace them with thicker ones. I imagine that the cam is somewhat shorter than it was when it was new. There is a bit of clatter from all of them although not bad at all.

Thanks again.
