Broken head bolt
Need help. My son-in-law broke a head bold off. He drilled and tried using
a eazy-out on it. Unfortunately a young would be helper with more strength
than brains came and tried forcing it and BROKE the eazy-out off .
It's Too hard to drill. Any suggestions would be appreciated.
Just happy it wasn't my TT
Thanks , Gordon Clayton gclaytonsr@yahoo.com

Re: Broken head bolt
Is any portion of the bolt sticking above the head surface? If it is, weld a large nut to it and try turning the nut. See a photo of the process in this thread.

Re: Broken head bolt
Thanks Mark but no such luck it's all down in the hole.
I have no idea how to help him. Too hard to drill and I doubt if it could be broken up
with a drift pin. I'm at a loss.

Re: Broken head bolt
You will need to remove the cylinder head in order to remove the broken stub - a bit more work involved but well worth the end result !

Re: Broken head bolt
thanks will let him know if he hasn't removed the head as yet.
Any thoughts on if an arc welder could weld something to
the broken piece ? I am not familiar with an arc welder at
all. OR what if he cut new threads further up and used a
shorter head bolt that he would have to make up. I know
we are not dealing with very high compression. As you
can tell, I'm no mechanic. I dabble mostly in wood.
Thanks for your help. Gordon Clayton

Re: Broken head bolt
Find your local Snap-On tool vender. They sell drill bits strong enough to drill an easy out or a broken tap! No idea of cost, but if that's what it takes!

Re: Broken head bolt
Another option after removing the head and hopefully you have a straight on access is to use a Hougen Brand Roto-broch. It is a hollow drill bit with a pilot. You can remove the pilot and carefully use either a 3/8" or 7/16' bit just enough to get around the broken piece. It has saved me many of times. Hope this Helps!
