Yeh thats the one !!, if the fella does that then he does not run the risk snapping the stud trying to get it out.

I watch these posts because sooner or later im going to need them on my 98 running OEM exhaust on untouched nuts ( all be it 16k dry only miles since 2001 ) like I said I am already soaking me nuts in preparation for the day

just ignore people saying the engine needs to come out to drill, it doesnt.

What's the one fazersharp ?
Mines is original too, 23,000 miles, '98 seen some rain I'm fairly sure, some with me riding it anyhow, and I don't think it's been touched before I got it! Just need to pray it all goes well when we have to do it ;-) I best start getting the penetrative oil into it now :-)

Geez Paul, are you saving up bikes? There doesn't look like there is any space for spare parts though ;-)

Re: Downpipe removal....Snapped things.... - anutz - 03-04-15

thanks all for the input - going to try the locked nuts method first, shall update soon...

Re: Downpipe removal....Snapped things.... - Jules-C - 03-04-15

If it's snapped off more or less flush with the surface of the clamp my preferred method is nuts like these eBay items 19053881990 or 281390078158. Saves having to do any drilling. Never found any stainless ones tho.

Re: Downpipe removal....Snapped things.... - anutz - 03-04-15

i think thats whats happened, i have just the "Nut" that snapped off in the socket - and its flush with the clamp - so fair bit left.....

Might take a look at these nuts before i try remove anything - and the rivet nuts seem a good idea

Have you got ebay links, i cannot seem to find those items?

Re: Downpipe removal....Snapped things.... - anutz - 03-04-15

OK found them.....sleeve nuts.....

They look ok, do you need to drill the clamp holes?

YES

Re: Downpipe removal....Snapped things.... - anutz - 03-04-15

Regardless of what i do - is this likely to be an MOT issue - assuming i either get them out and replaced or use some magic nuts, if its clamped properly etc...

Re: Downpipe removal....Snapped things.... - red98 - 03-04-15

As long as the exhaust is not blowing you will be ok.....if whats left of the thread is not damaged the sleve nut is the best /easiest way to go....use this method on my thou last year, will see if I can find the piccies.....oh, yes, you will have to drill the mounting flanges out a little, easy to do as soft like the nuts :rolleyes

Re: Downpipe removal....Snapped things.... - red98 - 03-04-15

found them.hope they help

Re: Downpipe removal....Snapped things.... - anutz - 03-04-15

What about using these, similar items mentioned earlier in the thread...

http://www.screwfix.com/p/joint-connector-nuts-m6-x-17mm-pack-of-50/83521

Still need to drill the clamps...

In your pictures, you seem to have a screw on stud extender....is that what they are called?

This was talked about not so long ago, what you need is a ----- damit I cant remember the name but it has a long shaft before its a nut and I think you drill out the bracket a little to accommodate the nuts shaft.Im sure somone will be along shortly and tell you properly

Edit------- they are called rivet nuts,
Search this forum for "snapped studs" you are not alone

Good memory, Sir. Here's the thread you need http://foc-u.co.uk/index.php/topic,12338.msg137697.html#msg137697

This bit

Good memory, Sir. Here's the thread you need http://foc-u.co.uk/index.php/topic,12338.msg137697.html#msg137697

So yes they are called rivet nuts and you do have to drill the clamp hole wider to acomadate them, or use sleave nuts or stud extender like has been mentioned. I would not risk getting the stud out, consider the snapped nut a warning

Re: Downpipe removal....Snapped things.... - fazersharp - 03-04-15

RED 98

Why did you use that extra spacer between the clamp and the bolt, was your stud extender poking above the clamp and is that extra spacer bigger than the stud extender so it sits over the part sticking above the clamp ?

made them myself, just a bit of tube that I cut to length and then ran a tap down.....those screwfix connectors might work, they wont be threaded all the way down though..cut the head off and run a tap down, should work and screwfix are open today....will depend on how much broken stud you have left weather you have to open up the flange holes or not, wont br much bigger,2mm at most I would of thought ..

yes, thats right fazersharp.the break in the stud was more or less inline with the flange.extra spacer just slips over the extension tube...might of been able to trim the extension tube a bit more and done without it but not much broken stud to play with....been on the bike for about a year now and no problems, much easier than boring it out Wink

Re: Downpipe removal....Snapped things.... - sinto607276 - 03-04-15

I've never heard of rivet nuts till now, and managed to get any stuck bolts out using the method I said before, maybe I've been just lucky? but always keen to learn other ways in case it's needed :-)

Re: Downpipe removal....Snapped things.... - Jules-C - 03-04-15

Didn't need to drill the clamp with the nuts I found on eBay. They are a snug fit inside Motad clamps. Original pipes clamps might have smaller diameter holes that need drilled?
