Stuck exhaust collars
I'm in the process of doing a general buff up of the TRX and I cannot get the exhaust collars off.
I've owned the machine for about 5 years and I've never taken them off and I don't know if they've ever been removed.
Before I start making a removal tool has anybody got any tips that may help?
The nuts have been removed and there has been a liberal application of WD40.
Any advise gratefully received
Cheers

Re: Stuck exhaust collars
If you got the nuts off thats a good start. Plenty of penetrating oil and perseverance should work once you get a bit of movement they should eventually come off. I tried to do the same on my 2006 BMW and snapped 3 out of 4 studs just getting the nuts off.
Keep at it,

Hi mikeyb90!
A quite easy way to loosen the collars is - riding it with the nuts removed
I didn't try it myself but someone at the German forum said so and it sounds quite good to me
At least it sounds like much less work and really worth a try.
Lazy greets from Munich!

Re: Stuck exhaust collars
Have a search on the forum: lets of info.
But no easy fix though. Problem is heat effect on different types of metal in collars and studs.
Try heat, WD40 soaking, Crowbar behind them (but watch fins on motor), hammer, chisel etc.....

Re: Stuck exhaust collars
Grind a U shape that will fit around the stud into a long(ish) slim metal chisel and hammer away............

Re: Stuck exhaust collars
As a penetrating oil WD40 is not very good, deisel is much better, The inside of the collar stud hole corrodes and closes the clearance. As above heat / cool cycles and liberal dosing of penetrating fluid will help, as will gently prying off from the rear.
Riding without the nuts isn't such a bad idea, but I would put a knackered old nut on one stud of each collar so it holds on the threads, doesn't stop the collar from working loose but it does stop it from running down the tubes and stops the header flange rattling around in the head.

Re: Stuck exhaust collars
Thanks everybody
I'll sort out some better releasing fluid or try the diesel
I like the idea of running the motor, that should put a bit of pressure in the right direction
Also: looks like this forum is quite active, which is good thing
Once again cheers all

If it's not made in China, it's a fake!

Re: Stuck exhaust collars
I recently had to tackle this issue as ea collar had frozen onto one of the studs.
The only way I finally got them off was by using a well made solidly built "Toyota" power steering puller (thanks dad)
I will get a photo of it the next time I am over there.
When I re applied the collars I coated the threads with Loctite nickel anti seize 771, to prevent this from happening again hopefully

Re: Stuck exhaust collars
It was a pitman arm puller so it's quite solid and chunky for a small puller. Others that are thinner will just flex and pop off. We tried
