Broken Exhaust Stud

Post by Scully » Wed Jun 18, 2014 12:53 am

I was removing my pipes and ended up breaking a stud. I have an idea of how to remove it by heating the stud with a blow torch and thrn using a pair of vice grips to remove it. I just want to see if this is the best method for removing it. Also looking at the gasket, I read on another topic that they can be hard to tell if they are there. I did a little digging and think they are but not sure.When I run my finger out the exhaust port I can feel a definite ridge which I think is the old gasket. Am I correct in thinking that?

Thanks

Good luck, you can also try an extractor tool be sure to block port with a clean rag if drilling into stud.

I use an 90 degree pic like a dental pic.

I never removed a stud but would probably try as you describe to start.
I only had one crush gasket on my front pipe- nothing on rear. That from the factory. I've heard of guys having no crush gaskets at all.
Aways put your brain in gear before you let the clutch out on your mouth.

If there is enough stud showing, slot it with a dremil tool. Then use an impact driver with a straight blade (manual type- Crappy tire $ 20)

If it doesn`t work-- drill 1/8 th and use a bolt extractor.

If these don`t work, check with a good mec type guy and use a Heli- coil. Check out Heli-coil on line.

Good Luck !! :pray:

I have had awesome luck removing broken bolts and studs with snap-on left hand drill bits, it comes in a kit with extracters. :clap: :clap: :clap: Usually the drill bit will catch the stud and spin it out.

I removed the gaskets no problem there. I tried to remove the stud by heating it but no luck there. I looked at Crappy Tire's website and a manual impact driver is $42. Going to try that route next. What a pain in the A$$ :swear:

Personally, I'd try heating the area around the stud without heating the stud itself....causes the metal to expand in the area around the stud, releasing it... usually better done with an acetylene torch. I've even used a wet cloth or paper towel to help keep the stud cool. I used to use asbestos wrap, but haven't done that in awhile. :doh: Then if you can, get a pair of vice grips on the broken stud. If the stud is too short, then cut a groove as indicated above and use a screw driver. I know, kind of a dicey job, but hey, that's how you learn to be gentle with exhaust studs. :wink: :anxious:

nothing to add to remedies offered other than for future fastener removal from things that have been heated and cooled repeatedly over time.It's a good idea to soak with penetrating oil, clean exposed threads, then soak some more with penetrating oil, before attempting to remove.
oh yeah, and give the penetrating oil some time to work, like maybe a day or two.

Well I am happy to say that it has finally been fixed. After trying it myself without any luck a guy that works with my son said he could do it. He has a bunch of experience working on Harleys for lets say 1%ers. After trying to get time that worked for him and me I finally gave up and took it to a car shop by my house and they removed them without any damage. :cheers: When I bought the pipes I ordered them through an acquaintance who owned his own shop making custom bikes. Great deal on the pipes. But when the :joker: put the pipes on he used lock tight on the nuts. Hence the problem breaking the stud when I removed it. Anyway it is done and I can finally get out riding.

:clap: :clap: :clap: Nice to hear it finally worked out for you. How do the new pipes sound? Any issue with the "noise Police"?

Glad to hear you got the stud out and fixed up :cool:

Exhaust studs should be made of some kind of unbreakable super steel :think:

Same pipes. Just removed them because I was getting some backfiring.
