I did something stupid while trying to get the valve gear to stop binding on an engine. I tried to rotate the stud that everything attaches to by putting the screw in with no rods on it to try to rotate the stud a few degrees and the screw broke off. Is there a way to get the old screw out?
What kind of engine and who made it? There are differences between brands so it helps to know this. The fix can be as simple as drilling out the existing screw and replacing it to having to purchase a new set of valve gear.
It is an IHC 4-8-2. I think it is about 8 years old. I hope I don't need a new set of wheels.
Carefully using a pin vise drill out as much as you can then using a verrry small easy out extract the old screw....
Yeah, you should be able to extract the screw and then just replace it with a new one. IHC used metric screws and the whole valve train is held together by tww of the same screws and some rivets. I don't know the exact size of the screw but any hobby shop should be able to match it up after you extract the remains.

On a lot of the IHC locos, the screw "screws" down into a small nut that can be accessed from the back of the driver. Using a knife blade, this nut can be pryed out and replaced with another nut and a new screw. The new nut and screw can be obtained from a junker, or used loco.
I went and got a cheap pin vise and got the old screw out. Now I just need to find a new one. I am hoping a local hobby shop has one since they do service engines. I might take the nut off anyway to try to correct my original problem. My drivers keep binding because the eccentric rod gets stuck on part of the frame.
