broken easy out....how do i remove it
 

So I was at the shop today getting ready to take my head apart completely apart and clean it entirely before re-assembling it. As I started taking off the water flange and some of the oil galley allen bolts, I broke off an easy out piece that I was using on the allen bolt that sits between cyl's 2 and 3. FACK! How do I remove it?! Its sitting flush with the bolt as well which REALLY sucks. The head is a 96 spec gsr so most of you can get an idea of what I'm talking about

can you get a pic up of the bolt and broken tool?

take it to a machine shop and have them take it out

Re: broken easy out....how do i remove it
 

not so easy out after all? :P

Re: broken easy out....how do i remove it
 

ouch...that is ugly...
+1 for machine shop...

Re: broken easy out....how do i remove it
 

i was at the machine shop when it happened! i gotta take it to this one place that has industrial drilling machines and either use one of their machines or HOPe they have an edm machine

Re: broken easy out....how do i remove it
 

whats an edm machine?
How about putting it up in a jig so its really stable and using a left handed drill bit in a drill press? I know that tool steel is super hard but they gotta have some kind of drill bits that are harder, right?
I assume you work at a machine shop, the other guys dont have any suggestions?

Electrical Discharge Machine- plunge tool, or probe type in this case.. it uses rapid spark discharge from the probe to the work piece to erode the metal. the probe never acutally makes contact with the work piece so hardness doesn't really matter.

it's possible to drill it out with a solid carbide drill, but those are pretty expensive for one-time use.. i would imagine you could get them in left hand..

i still say try to find a shop with an EDM. :thumbup:

Re: broken easy out....how do i remove it
 

Found a shop, cost me 81 bucks for their time to get the broken piece out :/


Another question, I told them to leave the old allen bolt in(saved me mulah) and I would just drill it out and retap myself, do they make oversized allen bolts and is it logical to go over sized even tho I still need to drill out?

Re: broken easy out....how do i remove it
 

Wow that EDM machine is pretty crazy!. Ive never even heard of that before.
So did the machine shop use an EDM machine to fix your head?
81 bucks isnt too bad. Its alot cheaper than a head!
I would only step it up if the threads are damaged, but thats just me. No sense in fixing something if its not broken. Im sure they make allen bolts in any size you need. I think theyre NPT plugs arent they?
