Stud removal

Christian Roberts /

So I'm trying to take care of a exhaust stud that I stupidly snapped the other day. None of my removal methods have worked so far. I don't have an extractor. Tried double nut but there wasn't quite enough space. Dremeled a slot for a flathead, aero kroil soaked, and still won't budge. I know you can weld a nut on, but I don't have the means to do that.

Any thoughts?

Maybe super glue a nut on ?

Re: Stud removal

You can weld a nut on with two 12 volt batteries, jumper cables, and a nickel. I saw MacGyver do it once.

Pics would help everyone here to ascertain the situation and the best method of removal. Words just dont cut it.

Re: Stud removal

Left handed drill bits. Harbor freight has them. Put them in a drill, drill in reverse. Drill bit catches and spins out the stud.

Re: Stud removal

Loctite and CRC both make freeze sprays that come out at -20 degree F and will make the stud contract and allow the liquid to seep in between the stud and the exhaust header. Alternate between a torch on the exhaust header (expansion) and freeze spray on the broken stud (contraction) along with a few gentle taps with a hammer several times and then let it sit overnight and it should come out with a needle nose pliers. All of the above ideas will work just be careful

Re: Stud removal

Same thing you do on a car engine block. Heat it up and turn it out. if its aluminum cylinder it should not be a problem at all to get out.
