Glad you found it! You are REALLY fortunate in 2 ways. First that you did the job before the whole thing blew up (which sounds like it was really close). And second, that the belt was walking off like it did. If the WP hadn't been quite as bad as it was, you might have not know about the problem and just buttoned it back up. If that had happened, something would have surely failed not too far down the road. All you lost was some time, and had some anxiety attacks. Might be a good time to buy some lottery tickets
