Downpipe removal....Snapped things....

[sinto]

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

[anutz]

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

[Jules-C]

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.

[anutz]

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?

[anutz]

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


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

YES

[anutz]

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...

[red98]

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

[red98]

found them.hope they help 

[anutz]

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

Still need to drill the clamps...


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

[fazersharp]

What's the one fazersharp ?

I was refering the the post before mine, this one

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

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 

[sinto]

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 :-)

[Jules-C]

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?

[anutz]

well, i tried to remove it and its sheared off flush with the head...


I don't think i can get to it to drill it properly....


What about taking the head off the engine......

[red98]

Be easier to remove front wheel and forks......if you remove the head you'll need a new gasket,£30 when I last bought one.....

[anutz]

yep i thought of that once i posted - so thats my next job ....what a nightmare!

[fazersharp]

AHHHHHHHH !!!I warned you TWICE

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

Its just from knowing myself, I have learnt with things like these that I am Frank Spencer and I know that I will beak it.

Sorry fella

which cylinder is it on?


on mine in the pic above it was #2, looking at it head on its 2nd from the right and i know you can get to both bolts on the middle 2 with a drill just takes a bit of origami with the drill to get it in.


failing that as above remove the forks

[anutz]

i wish i had listened to you Fazersharp...but i thought "i will be gentle...it will be ok....." it was not...i was not being rough with it, they just are so brittle!


Trying with a stud extractor kit now and then will give up and see about drilling it out completely.....


Paulfzs - its the 2nd cylinder so to the left of middle when sat on the bike.....just not enough room for my drill as wheel etc in the way


Can't stop laughing!

But surely anutz is a lot easier to remove the front end as apposed to the removal of the engine?

[anutz]

OK so managed to wangle my way in with without the wheel having to come off, no luck with the stud extractor


SO im stuck now - either i mess around drilling it out and then tap it ( i have never done that, and have no kit i.w. tap and die )


Or i take the head off and take it to a shop to get sorted ( never taken the head off either but i can see disconnecting things might be easier than working on the bike as it is - on its center stand


Any other ideas or advice

[sinto]

I think you can hire tap and dye sets, maybe from HSS Hire or somewhere like that, maybe worth trying your local yellow pages?
Where abouts are you anutz?

[Paulfzs]

surely someone on here will have a set you can borrow.


drilling isnt hard tbh, it took me about an hour to drill mine starting at 2mm going up in .5's just be gentle dont snap the drill bit.


taking the head off you need to take the engine out, took me 2 days to get mine out lol theyre a pain!!


then itll be £100000000000 to get it drilled out.


do it yourself in under 2 hours no problem
