Fitting new gasket into silencer


Gray
 Share

Recommended Posts

I've bought a new gasket to fit into the silencer part of the exhaust to get a better seal on my Beowulf.


The gasket doesnt push far enough into the silencer tube because the top 1/3 diameter of the silencer has ridges inside from some kind of welding. The remaining 2/3 is nice and smooth. Currently there are a few tiny gaps at the base of the slits on the silencer where the gasket doesnt slide under.


Am I ok to file these ridges down to make it smooth enough to slide the gasket into the silencer so that the slits have the gasket underneath?


Can post photos if required to make it clearer.


thanks

Above you can see the gap (picture is sideways) where I think the gasket should cover. I also have a jubilee clip to fit around the outside but is the gasket supposed to slide inside to cover these gaps on the slits completely?

In the top left corner of the pipe you can see the welding ridge, running my fingers around the remaining part of the 'circle' is nice and smooth. Obviously this ridge is preventing the gasket sliding all the way inside.


Should I gently sand/file it down to make it smooth like the remaining 2/3 of the circle?

It goes in fine.


The gasket gets squashed when I try to push it further into the pipe.

I think I'm going to buy a small round file and some sandpaper and clean the inside of the pipe.

That's what I'd do, mate....... :wink:

Thanks for the replies.


It only took a small piece of sandpaper to remove whatever it was in the pipe. Maybe it was some kind of thermal paste. It was rusted now whatever it was.


Gasket fits fine, put on the exhaust and secured with a jubilee clip.


Only need to change oil filter and fill with new oil then I can start the bike. Been off the road since early October so am hoping there won't be any further problems

I've had the bike running today and when I put my hand at the bottom of the seal where the gasket is I can feel air coming out.

There is still a huge amount of air coming out of the end of the exhaust and it makes a great sound.


Would it be worth taking off the jubilee clip and covering the whole of the joint in exhaust tape from Halfords then put the jubilee clip back on?


something like this ? http://www.halfords.com/motoring/paints-body-repairs/head-gasket-exhaust-repairs/holts-gun-gum-flexiwrap-silencer-repair#tab1


Obviously this gap needs sealing but even more so as I am going to try and schedule an MOT for tomorrow or Saturday so I can be mobile again.


thanks

if its only blowing a little a bit of paste will possibly work


on larger holes the paste will shrink and crack with the heat and fall out!


its not uncommon for joints to leak a little
