Well today I tried a fluted extractor on a 1/8" hole drilled in each one...no movement what so ever. I was being careful not to put too much torque of the extractor, but I guess I must have fatigued the metal after an hours worth of torque, heat cycling and cooling with penetrating fluid and the extractor broke off in one of the bolts...

So now I'm thinking of just putting the stator cover on with those bolts missing....they are on the top of the cover and should not cause and major leaks, at least not to start with.

The thing about extractors is if the broken bolt doesn't come out first time don't screw with then I mean heating and putting oil on them over and over just drill them out put the thread repair of your liking and be done with it as the broken extractors are hard to drill out Ken

The one bolt I'll drill out as close to the threads as I can and see if I can tap it out. The other one with the broken extractor...I have nothing to loose on that one so I'm going to weld a washer then a nut and see what happens.

Well with nothing left to loose on those bolts I first built up the bolt where the extractor broke off with weld since it was recessed a bit, then I welded on a washer, and then a large bolt. First bolt did not have good penetration on the washer so it came off when I started to try and remove the bolt, second one did the trick....bolt started to move and I slowly and carefully loosened and tightened little by little until it came out.....Whooo!!! Chased the threads with a M6x1 tap... threads are not too bad.

The other one I decided to drill it out, was a tad off center so had to use a carbide bit on my dremel to bring the rest of the bolt out to the old threads. I then worked the tap down and in a few times....top 1/4" of the threads are pretty buggered up, but the rest are pretty nice.

Think I might use a dab of blue loctite on those two bolts once I have a fastener in there,
So all in all not a bad outcome I think.

Sweet, you got to be the windshield instead of the bug this time.

I was gonna say: There's always JB Weld!!

Glad it worked for ya. I usually don't mess with extractors, unless I'm more then 75% sure it'll work.... Welding works 99% of the time (just not always the first try haha)
