Cheap Arse Clamps on the Exhaust how

[xlr8tion]

HEY SO YOU ARE GOING TO PUT ON SOME TORS.....But how do you...

Remove the broken tail of the bolt from the Clamp?

Triumph makes the clamps out of SS and the bolts are galvanized and soft, I think, so they will sacrifice if you try to over tighten them and crush the pipe or cat outlet and conversely they snap when being loosened so the techs can get them off in one revolution and charge you for a whole new clamp.

I got some absolutely mint tors with perfect gaskets and the clamps had bolts snapped on 3 of the 4 clamps(manifold and two of the three tors)

I have soaked them in Vinegar to dissolve the rust then I will soak them in Kroil and try to make the three turns clockwise with a vise grip(then the end of the bolts threads are ruined so its only coming out that way..No reversing it....


Does anyone else have any idea how to remove these soft bolt frags out of the clamps so I do not have to fork over 40 bucks for a set of 4?

Attached is a pic.....

Thanks...Greg

Did you try heating the clamp?

I'd put it down to the neglect from the PO. I've never heard of problems with the clamps and had mine on and off numerous times.

You're not going to put ketchup on that clamp are you?

250 miles of neglect...These were pulled off new and Jardines put on immediate...There is hardly any carbon on the muffs and the cat looks NOS.

My hypothesis is these are soft iron bolts with a slight galvanic coating....You'd want them to be sacrificial rather than have some hack tech get all torque happy and crush the inlet and outlets on the cats...

I am not asking whos fault it is..I am asking how to get the bolts out...

These bolts are like the Bevel box drain plug, IMO-Just a higher NM snap off value....

My bike that I am putring them on has bolts that are FUSED IRON OXIDE to the clamp...They will snap on the first quarter turn.

I'll clean the cat bypass pipe with molasses and water and it will do just as good as a job as soda blasting...Seriously!

OH ya the things you can do with Molasses. We have a great history with molasses up here in Boston. Boston's Great Molasses Flood of 1919

That curse is deep and wide. We only have a few left and the curse will be over.

Step drill to the tap drill size and remove the buggered threads and tap. or remove the weld on nut and add another. Seriously though I would just remove them and buy new bolts from the local hardware store. You might want to check with a local machine shop. Myself I would just pop them in my mill and be done with it but then I might have run machines for a bunch of years. Use some thread butter when you go back together with them. A new bolt is with the new clamp along with the cat delete probably 8mm So you could get away with tap drilling with a F drill .257" and run a 5/16-18 UNC tap thru her. Then you can use a american bolt
