I have a few ELGIN pocket watch movements that have bad forks. My question is how do I take them apart to change the pinions. It looks like it unscrews but I don't want to attempt til I have some advice.
thank you

Unfortunately for answering the question Elgin watch company made lots of different watches and without seeing a picture or which pallet fork were discussing it's hard to give an exact answer. So basically you're dealing with either screw in or friction in. To give you a clue I'm attaching a page out of the 1915 parts book.

Hi PostalWatchGuy,

If you try and unscrew a friction fit arbor, you won't do any damage and it might still come out. However, if you try and drive out a screw fitting one, you certainly will do some damage, so always try the screw route first. BTW, they're arbors with pivots, they don't have pinions.

Regards,

Graham

Thank you for proper part name. It does show threads like it is screw on. Does it screw clockwise or counter clockwise.

Counter-clockwise to unscrew, like a regular right hand thread screw.
