How remove broken bolt?

[showcrop]

What are those called?

I looked and looked before posting and all I could find was "extractor"

In my experience, easy outs and extractors work on things that are easy to get out or extract.

But... I still try them... my set has about 2/3 of the originals; because the other 1/3 have been scrapped after snapping off in things that aren't so easy out or extractible.

In those cases... then you have to figure out how to get the broken easy out... out... and if it breaks short... good luck... and they don't drill easily, because they're hardened steel.

So... anyway... if you use an easy out... or extractor... try the tips above with a little heat and/or penetrating oil

BUT... BE EASY ON THE EASY OUT!!! If it doesn't work... pull it out before it breaks.

At least then, you'll have an easier time drilling and re-tapping.

And all this is what about five of us like about this particular type of extractor.

Okay thanks for trying!

I agree. I also stand by... harder to snap... is still possible to snap. One of the most important things about using any kind of extractor is to know its limits; because if they break, you often have a bigger problem on your hands.

In a practical sense, my problems with snapping have usually occurred when I tried to use adapters and such to get more torque on the extractor. If I had stuck with the handle or chuck that came with the extractor, there would be less chance of snapping it.

Which... I guess I'm saying... be smarter than I was...

It's hard to tell, without something for scale, but I think this particular instance is too small for one of my broken pipe nipple "cheats"... which is... If I can get a small chisel in there and get a bite around the edge... in some cases, I've been able to deform the piece enough by pounding the edges towards the center... to simply pull it out with a pair of needle nose.

What's the appropriate tool to remove this broken bolt? This is a hydraulic limiter/regulator from a JD 7100 planter, for the markers.
The adapter broke off, at the top, in this picture, I want to get it out.
It's hollow.

Is there a screw that I can screw in one way, tighten it up against the the broken bolt/adapter, then turn it the other way to back it out?

What tool/screw should I use to remove the broken part?

Thank you!

None of us commenteers have mentioned one thing that might be advantageous in your situation... your regulator is hex shaped...if you use any type of extractor... after you have applied your choice of heat/penetrating oil, etc...

When it comes down to it, you might be better off clamping the whole shebang upside down in a good vice that can grip the extractor right where it goes into the regulator... and then using a socket and T-bar on the other end of the regulator to turn the regulator itself... but be gentle...

I recently ran across a reference to this product: CRC Freeze-Off Super Penetrant. Seems to be available online and at many auto parts stores. If I were you, I'd try it on this. You super-cool the remains of the bolt and then try your Easy-out or other tool. Assuming the guy working on the old JD A in the video wasn't using smoke and mirrors, the product seems to work. It works the opposite of heat: instead of expanding the outside, it shrinks the bolt. Worth a try.

I had to pull brass plugs out of aluminum castings in my younger days. If the plug wouldn't come out, I used a propane torch to heat the casting. If it still wouldn't move I drilled out the center of the plug and chilled an EZ out with CO2. The cold EZ out shrunk the plug enough to relieve it from the heated casting. I can't remember ever having to drill out the plug and install a heli-coil.

Those are fluted extractors

This sounds a little crazy, but I worked in a power house and we used a cutting torch to remove steel cap screws broken off in cast iron water softeners. The bolts will melt out before it harms the cast. I once had an exhaust stud broke off in a Ford manifold. I figured if it worked at work it should work at home. I carefully burnt the stud out, chased and cleaned up the threads and it worked well. just my experience.

That is generally true. As you are heating one part and it is turning red, it is obvious that little heat is making it to the adjacent attahed part.

Perfect, thank you!
