Exhaust Hanger Vibration Damper

Post by Harrymail »

On my GT550A, I just want to check that I am placing this item in the correct place. The parts diagram shows that it is placed last on the hanger bolt, with the washer and nut against it. It looks though that it would make more sense to place it between the two exhaust hangers. At present I am having trouble with the LH Outer exhaust touching the frame near the front foot peg and want to make sure I have everything correct.

Anybody know the correct positioning ? Also anyone else had trouble with the exhaust touching the frame ?

Cheers, Paul

Harry I put the washer between inner and outer exhausts myself. As you say it makes sense that way. I also make sure there is a washer between the exhaust and the frame to allow movement between the two.

The thick washer in the picture is designed to slot into the mounting hole of the inner bracket so that when the two are held together it provides a location for the anti vibration pad to fit to. The flanged nut then goes over the pad. If the thick washer isn't located properly then the inner bracket position will be wrong, only by mm but it could be enough

Thanks Barney & Canaletto. I have had the vibration spacer in both these positions, and have made sure that the ring spacer is located within the hanger for the inner exhaust. Works fine on the RH side of the bike. But on the LH side the outer exhaust touches the frame. I have removed the exhaust and had a look and it would appear that it has been touching the frame for some time. Also it looks like the centre stand is also touching the exhaust. The exhaust has marks in two places where the frame / centre stand is touching the exhaust. Picture below. Its only the outer exhaust that is a problem. I'm just putting the bike back together after the engine has had a rebuild, so am trying to get everything spot on. I am beginning to think that something is bent somewhere. I wonder what is the normal gap between the frame and the LH Outer. Perhaps the bike has fallen over at some time before I owned it ??

Just confirming you have a cushion fitted on the stand to protect the exhaust?

Yes, the cushion is in place. I have learnt from the previous owner that he dropped the bike on the left side on his drive. The stand saved the exhausts. I am thinking that the stand may be slightly bent. Something else must also be bent for the exhaust to touch the frame though. Possibly the frame itself is bent at the hanger. Will see if I can take some measurements tomorrow.

Got the exhaust on satisfactorily in the end. I put a piece of rubber between the frame and the exhaust. Tightened the header first, then the hanger bolt. I then removed the rubber and the exhaust clears the frame by about 5mm. Will do for now but will have to keep an eye on it as it may slip back against the frame.
