RL, the only thing that would allow movement if all is tight would be the spring compressing, maybe they are supposed to do that. All I know is, I can very well remember thinking similar thoughts years ago and while having someone else move the wheel while I felt just how much it was moving around in the slot, BAD IDEA! lots of pain! That was about 1979, I don't remember what I did. I know I didn't file or grind anything. But I can still feel that pain! PS don't tell anyone, Jim D
