Exhaust Header Stud

Postby fnickel » Tue Mar 26, 2013 6:18 pm



'92 1500 SE. One of the studs snapped while trying to get the nut off where the header pipe enters the cylinder head. The stud broke at the base of the nut, so there is still a half to three quarter inch of the stud exposed outside of head. My question is, how is the stud secured in the head? Is it threaded in (like other bikes I have) or is it secured in some other way, like a pressure fit or something else? This will help me figure out the best way to get it out and replace it. Thanks again for all the valuable information.

Fairly sure just a regular stud..like on 1000' sand 1100's and 1200's..so heat/atf-acetone soak/ etc.etc. be careful if you break it off head could be toast..

Apply some good heat around stud to aluminum not propane (not hot enough) and use one of these tools. It will grip the stud tightly and keeps turning torque in line. BTW it is threaded.

Yes, it is threaded into the head. I was able to lower the exhaust enough to clear the broken stud. I gave it some tapping with a hammer along with penetrant, and was able to get my vise grips in to get it moving. It moved relatively easily, and I was able to turn it all the way out and remove it. It has about 10 or 11 threads on it. Good thing it is a larger diameter than the lower portion that the nut attaches to. Now, I just need to order a new stud and nut, and I should be good. All this to get at the shifter shaft oil seal. I still need to find out how to remove the left side exhaust or lower it far enough so I can get at the seal. Are there exhaust seals or gaskets up in the head, and do they need to be replaced each time the header pipes are removed?
