Thread dial disengaging

You should easily be able to see if the screw is bent by running the lathe and looking at the screw rotating.
 
thanks, tomorrow or Sunday I'll dial indicator it if it's not visible
 
I did move the lathe with a strap ...

That could do it, although I hope this is not the case. I can't see what else would physically kick out an indicator, though.
 
I have the Australian version of the SB9A. On mine, there are two setscrews on the shaft that holds the thread dial in place. One on the dial body and one one the apron. On mine, they are both on the front, but the pictures I've seen of the SB show the dial screw on the top and the apron screw on the front. If one is loose, the dial will still be able to rotate too easily.
