Removing Exhaust Studs

Hey,

I went to put my exhaust on yesterday and managed to strip a stud. Theres no way to thread a new nut on to remove it.

Theres one stud holding the pipe onto the engine. The other 3 pipes are fitted tightly.

Whats the best way to remove it? Will it be possible to run it with just the one stud?

My dads a sheetmetal worker so i may ask him to weld me a nut on and see if it will come out that way.

Would a stud extractor remove the stud? (Maybe a stupid question)

Cheers,
Shaun

A proper stud extractor would probably shift it, one of these not the drill screw in type

Welding a nut on like you suggested is also a good way, you might as well get it out, it's best to have them fitted as it will probably eventually blow with the strain on the other stud.

Do u know the exact name of them?

Cheers again,

They are just "Stud Removers" as far as I know, you also use them to fit studs as well
Machine Mart sell them or you see them on some of the specialist tool stalls at car/bike shows

go straight to that type IMO dont mess around with other methods.

i started with two nuts on the thread that was left to try and get it off by locking them which stripped the thread off then i tried a blowtorch which did nothing but turn the stud blue. i then tried cutting a slot in it which didnt work either.

i then bought a draper extractor, https://www.amazon.co.uk/Draper-14156-Stud-Extractor-6-19mm/dp/B0001K9Q1S/sr=8-1/qid=1160058961/ref=sr_1_1/202-7177073-8876633?ie=UTF8&s=diytools , which didnt work...its just seems to mash up the stud so im about to buy a set like the ones above and i hope to god it works Exclamation

I'm not sure I'd heat the engine with a blow torch. However, heating it up is a good idea so if you can run the engine to get it warm, it wil make life easier. Use some penetrating spray like Plusgas (NOT WD40) to help.

Definitely go straight to the good stuff. When getting the pipes off the Thundercat, 4 of the 8 just snapped off. Not that it mattered in that case. Laughing

I reckon if your Dad can weld a nut on, this is your best chance. There is no better way of whacking a huge amount of heat into a seized joint. Just be careful not to get any spatter in through the exhaust port.

Top Tip: Go to a specialist fastner suppliers and buy a handful of BRASS M8 muts. Use these on the exhaust studs. They are softer than the steel of the studs so if they seize on again in the future, you can just welly them off. The thread in the nut should strip before you risk damaging the studs.

Stinkwheel's advice will do the job perfectly. Get the nut on as far as you can then cut the stud off flush to the top of the nut and then weld it. Should come out easy then.
