Help with stuck trombone

[Shasta]

Hello fellas

I cannot get my right trombone out.  I spoke to Mark and tried prying the bone down with large screwdriver while yanking on the handle with large vice grips to no avail.    Does anybody have any suggestions or advice?  Thanks for the help, Matt

Matt,

Got another idea to try.  Go take a ride to heat the exhaust up.  Then put on some leather gloves to protect from the hot parts, and give the tools method I explained a try with it hot.  The heat expansion could very well make the difference.

For others curious about this:  Maremont changed the ID of the Cherry Bombs - made them bigger.  Such that I can no longer swage the ID with a die to make them closely fit the TromBones.  Now they will rattle unless I changed the build.  So I now install welded-in shims on both ends to cradle the Trombone.  It's now more difficult to build the system with bones and more costly - so the cost is increased while we lost adjustability - they must remain full length.  Also they are now assigned left & right - not interchangable because the fit is much closer and the tubes have enough variance to make them have to be assigned.  For these reasons I no longer encourage the purchase of Trombones.  On Matts, I tested their insertion and removal several times during the build and at QA inspection. They went in & out snugly but repeatedly w/o needing tools.  Now that he has them, has installed them and heated them up, and I can no longer put my hands on, of course now they get SNAFU'd.  Murphy's Law. I am confident it's because of the sharp edges inside, of the welded shims and the edges of the little perforations gripping the close fitting Trombone.  I suspect he doesn't have sufficiently sized tools as I do, to force the removal. (And then make an adjustment to the latch so tools aren't needed while it breaks in.) Frankly I can't imagine anyone on the board having better advice for Matt than I do, being as how I know his system intimately, I built it, and this is a new problem brought on by Maremont's change.  IOW - this is new, and very few folks have Bones built with weld-shims. But if you have an idea, let's hear it!

Before MarkT's reply, I was going to suggest getting them up to temperature and trying again. If that doesn't work, with the pipes hot, use some air-in-a-can (computer dust blaster) to spray the cold air at the trombones, then yank.

BTW, I'm not speaking from experience as I don't have MarkT exhaust.

"Yanking on the handle"?  I hope that's incorrect description.  It needs to be lifted high and pulled hard (if stuck).

don't know the actual design of Mark T's trombones, but when I pull the cores from my viking exhaust I have heated up the outside with a heat gun expanding only that. works every time.  running the bike heats up everything and everything expands, might work might not depends on the design.

Thanks for the tips.  I'm going to give these different heating/cooling techniques a shot tomorrow. 

Mark I did lift all the way up on the handle and pulled hard...up and out.  I'll report back and thanks again for the help.
