As far as I can tell it's a friction fit and should just pull off. Probably it's a friction and corrosion fit by now. Does anybody know any tricks for pulling off the socket and needle hub without snapping the shaft?
I thought about adab of penetrating oil like PB Blaster, but they are pretty small pieces.

Some insist that you have to twist off clockwise, I have wound up with many 'clock spring on a stick' so the trick is to remove the needle at the junk yard, and if it does not work, try another speedo.

If you can get the outer piece to expand more than the shaft, it might come off. I'd hold a match over the round disk and let it heat from the bottom of the flame, no warranty implied or otherwise! Or touch it with a small soldering iron. It's not plastic, is it?

I twisted carefully against the stop (counterclockwise) and gave the needle cap a slow firm pull. It came off as advertized. Maybe it was just luck. Anyway it saved another trip to the junk yard that tpsierra recommended. I didn't get around to trying heat on the socket. Probably a soldering iron would have been ok. But this time twist and pull worked just fine. Thanks a whole lot for all the good advice. Somebody oughta write a book.
