Removing Exhaust a Stud

The MIG welded on bolt was going to be my orginal plan of action, but I was hoping to maybe find a solution that would not need me to get the bike somewhere. So hopefull the stud remover should work a treat... I'll let you know how it gets on. I'll also have to give blueto a text and see if he found his, else I to will be going to Machine Mart or something to get one.

Whatever you do don't buy the set from halfords, me and my dad snapped the first 3, it would appear they are made out of silver toffee.

Next time grind half the nut off, then tap the rest of the knackered nut off it with a punch. As soon as you've broken the side of the nut, stop so you don't weaken the stud more than necessary.
Or use a nut splitter if you can get one in there?

Yep, appears that I did remove the nut all wrong, something to remember I think. But aleast I know for next time, splitting the nut would have made things much easier, though thats a lesson learn't for me.

I'd definately be mig welding it now.

The "easy out" type things are absolutely horrible, they;re very easy to snap. And also very hard to drill out.

Could you remove the head and take it to your mate to avoid riding it without MOT?

err... not ever taken a head off myself, that could just lead to a whole world of complication.

Hi.

I had my own nightmare with this last summer. Broken bolt in head for front pipe. Steps were as follows:

Drill through broken bolt using 4mm drill.
Use easy out.
Easy out broke.
Order Cobalt drills of various sizes.
Drill through broken Easy out
Use another easy out, heat and WD40
Easy out broke.
Drill through Easy out and snap Cobalt drill in there.
Remove head and take to engineering firm in Horndean
Firm drilled 1mm hole, partly in head and partly in remnants of old bolt.
Firm centre drilled waste to about 5mm so not to damage thread.
Firm then peeled out waste of bolt.

This drilling technique will require you to level off the broken bolt with the head so you can drill the 1mm hole.

p.s. The engineering firm charged me £30.

Best of luck.
Tim.

Never cut the stud, always cut the nut off of it.

Had a similar problem of my own recently when I undertook an engine swap with my pater, about same sort of stud length left sticking out too.

Plenty of loosening fluid required, and we used a pair of mole grips to hold the stud. I was fortunate with how easy it came out to be honest, but the method used was spray with penetrating oil, leave to soak, spray some more then have a go at getting out, keeping constantly spraying with oil as it is extracted so it's well lubed up

Mole grips are pretty useful as you can get plenty of squeeze on the stud, and if this fails you can try other methods. Up to thee though.

This is the said stud -



I'm hoping I'll get it out with the stud remover.
