Exhaust studs

[Crusty Snippets]

Heating

Heating the studs is the ONLY way that works. Heating the aluminum is futile. It dissapates the heat too quickly.

The studs might need to be heated (to an orange/yellow) repeatedly to get them to release.

I can not agree completely with the above. There can obviously be more than one way to do the job. I can agree that heating the studs is what worked for others. And I will make note of the technique.

However having just removed the four studs from my 400 Seca without any breakages or drama, and using a stud remover. I have never broken a stud, and removed many over the years.
Using two nuts is a good plan for installing the studs IMO. But for removal the nuts are further from the base of the stud than a stud remover would be. The extra distance IMO causes the stud to twist rather than break free. The stud remover can put tension on the stud at a closer point to the base. With a one foot bar, a hard yank creates more pressure on the inner threads.

It is possible that I could have broken the same studs as you guys. But there is always more than one way to do a job.
Sometimes it might be the right way, the wrong way, and my way.

Thanks for the help!!!

Thanks for all your help guys!! I used the torch and heated it and turned it out gently with a pair of vise grips!! Question though, I need to buy a few replacement studs. I'm assuming I can get these at the Yamaha dealer or equivalent bike dealer?

Thanks again I really appreciate the help.

You can get them pretty much anywhere as long as you know what length, size and thread pitch. They are nothing special.

I keep a rod of SS all thread around and just cut one off when I need it.

Thanks!

Thanks I appreciate the info. I was looking for a long threaded stainless steel rod that was the right size here tonight so I could cut to the size I need but couldnt find any metric size only standard!? In a country that has spent so many tax dollars converting everything to metric for the past 40 years one would think you could find one!!

Thanks again!!
