my fault! nothing personal. I was searching forever and all threads I found said "search", this one just sent me over the edge. I found this and it was quite helpful but not complete. hopefully it helps somebody else. I got the odo out and found the slipped gear, I will try using some adhesive to fix it.

there were some threads about this issue a while back but most don't exist.
