Broken bolt removal

[Ploddit]

Any hints for this:

One of the rear mounting bolts for the standard bashplate snapped (even after copious WD40 over a week).

Its in a removable chassis part (51502 i think)

I was thinking of trying these facom reverse thread extractors (eezyout type). But I think it'll be hard given the difficulty to drill the bolt.

Or this type:

This type is another alternative as I think if I can remove the part I'll have 10mm or so I could grab.

I've got no idea which tool would be the most effective as I don't meet rusted in bolts in the South of France very often, but hopefully someone has more experience than me.

Thanks

I've had success using an Allen Key as a broken bolt extractor. Just find a suitable size (quality allen key of course) measure across two corners, find a drill just under size, drill bolt, hammer in the Allen Key and use this to remove. Then six corners give really good grip over the full length of the hole if you choose the correct drill size.

Yes I work/help out at a motorcycle garage and they use a similar technique but using torx bits with a 1/2" drive....

I'll just try and remove the part and try cheapest first.

Must remember that and try it next time.

Funnily enough I did the same to one of my bash plate bolts recently, so all this is very handy. Would never have thought of using the allen/torx head method.

Nice one chaps.

Hmmm so cheap this one:

I've had another bolt tig welded on before and the heat aids removal as well.
Also in my experiance if the eazi out snaps you is buggered.
don't like them.....but thats me
If its not a blind hole i have also just increased drill size till whats left is
minimal then used a flat face punch to distort the remaing bolt fragment
to the point that a pair of snipe nose will twist it out.

OFC liberal heating with hot air gun is a winner too.

Just redid a 6mm thread for the timing belt tensioner.

Reminds me how good these are, easy and better than new repair....

Timesert inserts are the boys`s! Saved me a few quid when some numpty stripped the tensioner threads on the missus` astra timing belt

If there`s a bit of thread stuck out the other side and you can get to it I`ve had a really good few success storys by screwing a nut onto the exposed thread and MIG welding it on, as previously mentioned the heat helps too, deffo worth a try.
