P gasket replacement time - the lower bolt on the alternator has sheared - the remains look like it was previously overtightened, as its not fresh metal on the sheared end.

I can't grip it with mole grips, I can't find my 'easy out' set, I don't have a hot enough flame, or a welder.

I can't put it back together with just the top bolt as it will rotate without the bottom bolt in place and throw the belt.

On top of that, it has just started chucking it down my shed is too full of wifes stuff (somehow) so I can't retire there either....

Out with the chisel and big hammer I think!

Have had more failures than successes with Easiout's. Hammer and chisel usually sorts it

Tried that first, now the whole thing is so far down the hole, I can't even get a punch on it. Drilling right through is the next option, from the rear !

What make, James? The bolt around the extractor is collapsing, so I was hoping to get it punched out from the back.

mines a snap on badged one they arent cheap ,drilling out and a recoil would be cheaper

I should have just drilled out in the first place. Damn screw extractors. Its not shifting.... I have nothing hard enough now to drill the extractor out, and a new bracket is £250 + vat.

I think I can use the PAS pump mounting bolt and a bracket from that to locate the bottom of the alternator - which is all the bottom bolt seems to do anyway - assuming the PAS pump and alternator are reasonably in line.... I can't see at the moment as its all in bits.....

If the brackets off the block.

Phone locally see if any engineering companys see if anyone has a spark erosion set up.

I had to get it done once when a jnr eng snapped an easi out in a blind hole in the african jungle.

50 dollar but saved hours of grief

Try a Colbalt drill slow with some oil as lube

Problem with trying to drill out a very hard item (screw extractor or bolt) in an aluminium housing is that the drill is very prone to run off centre, giving you a big hole, not where you want it

Thanks for all the suggestions . I put it all back together and used a repair washer on the nearest pas pump bolt to stop the alternator pulling onwards . Bodge .

You can see the bolt had been like that for s while and it seems like it was screwed in to the alternator .

If you can get to the rear of the sheared bolt you could try drilling the bolt with say a 3.5mm drill up to the end of broken extractor, you may then be able to get a 2.5mm punch on to the end of the extractor and give it some sharp hits with a hammer. The shock may cause the extractor to unscrew and pop out the remnants of the bolt. at least that may allow you to drill and helicoil the hole, failing that it is probably spark erosion time

The only one on eBay I am all sorted thanks - if the imaginative engineering solution doesn't hold, I will have to replace the bracket.

That's not too bad a price (inc postage), would cost you more than that to have the extractor spark eroded out of your one. I would bite the bullet and go for it, less chance of it letting you down in the future if your temporary repair were to fail (and no it isn't me selling it)
