How to remove broken header bolts

[Eric G]

Take a look at machine shops in your area that work on diesel engines. They usually have EDM's (electrical discharge machining) that will remove the bolt in place.

Several of our agricultural machine shops here in our area do this when just this type of event happens. They usually charge about 150/hole. Heck, if you weren't so far away I have one in my lab for a project I could haul out.

Best of luck!
