Any ideas of the best way to go about tackling these, ive tried drilling through one and using larger size drill bits to increase the hole, but the only one that managed to get through was a tiny one, the others are just going blunt (HSS cobalt Dewalt drill bits :( ). drivers side needs 1 drilling out, one stud actually undone, and one nut came off as normal, passenger side how ever, 2 snapped 1 undone as normal.

 

I can not for the life of me get this damn drill bit to eat the stud that's in there, so at the moment, my clutch change is on hold. i want to get these elbows sorted while the gearbox is off the car as i have more room to play with.

 

I have a stud extraction tool BUT, last time i used one the damn things snapped in side the stud so that left me back at square one where by i had to then drill through that and the stud (when i did my blue car) so im a bit apprehensive about trying that again.

I don't understand what cutting the v into it does?

 

Do you the crimp them both together and hammer them through?

 

Not sure my self, think it releases the clamping force on the stud, but leaves enough metal to use a nut and washer to bolt the exhaust up with.

 

All i know is i put the V in, sliced through the stud, then hammered the two parts loose.

If u used a 0.8 slitter could have cut one straight line, had 0.8 gap in middle of the stud missing poked stud out and still had the thread so no need for the nuts, just new bolts..

 

Done it to mine never had a problem after that...

would rather just use nut and bolt rather than screwing into the thread again. its much easier later on if the exhaust ever needs to come back off, if you snap a bolt thats gone rusty, you just replace it, rather than all this drilling and cutting V shape milarky lol

So once you cut it do you crimp both sides together then tap it through?

 

What's the pont in using old nuts with new bolts. Just replace with new surly?

cut both sides, no need for a large V, just enough so you can cut the stud in half, this gives you the chance to hammer both halves together so they come away from the thread holding them, and they basically drop out.

 

No point using old nuts and bolts, but if you put the exhaust on, and need to take it off again and the nuts and bolts are still in newish condition, can use them again, but my point being, its better because if the exhaust has been on long enough, if the bolt snaps, you just pull it out and replace, none of this drilling crap or cutting V shapes.

Oh I see I think. You cut the line through the nut and bolt. So the bolt stays in place but the rusted nut is removed in 2.

 

Still doesn't help with the snapped nuts lol

Yeah that's what I was thinking lol.

 

So are those studs threaded into the elbow or pressed in from the other side like the wheel bolts?

Its a stud with a nut on it if stud snaps, cut through the middle of the lot it will come out in 2,

If use thin slitter can use same thread size has studs in bolts, or nut and bolts and go right through. .

Think you are getting confused with the two issues lol

 

On the original elbows its studs screwed into them with thread to use a nut on to hold the exhaust in place as per this image.

 

 

as you can see, due to age, heat and just being a stupid design, the studs thread had rusted to the point where undoing the nut, snapped the stud (as per the image above)

 

To get the stud out, i had to cut a V section into the elbow and then cut through the stud, i then hammered the two halves of the remaining stud together to get them to fall out.

 

For the replacement exhaust, ive use Nuts bolts and washers to secure the down pipe to the elbow, a much better design as if i need to remove the exhaust at a later date and the bolt snaps i just replace the bolt, rather than having to drill out snapped studs and add V shapes to the elbows.

 

Hope thats clearer.

damn it wrong image lol

 

But if its snapped up to the flange this cannot be done can it.

 

I cannot get my head around it without having the part in my hand :wack:

Right so your cutting the flange as well

Just slit it like this right through flange and stud the 2halfs of the stud will fall out leaving a threaded hole with a small slit in the flange on one side.

New nuts, bolts and washers,

 

And your away lol..

the above image is my actually elbows ive just sorted out.

 

with the power of paint invested in me, basically cut out the black painted on parts in the below image with a angle grinder.

Thats much better then my drawing lol, I did do mine on my phone.

Don't say u did too, cause I'll look even more crap at drawing

Ah simples lol

 

I thought you were cutting through the length lol?

 

So you could do it my way as well if the studs didn't snap :-)

whats your way, and we want paint diagrams, image is available on the first post lol

Cut along the length of the bolt with the nut still on, then the nut can be removed as its in 2 and the stub stays in place?

But the issue then comes with getting another nut on the stud, think you mean one of those nut splitters. just cut the nut off. problem arises from the fact there is nothing protecting the thread out in the air, so over time with heat, rust, cooling and what not, it goes rusty, expands then the bolt cant undo so ends up snapping the stud.

Shut up I know what I mean. Its been a long day as you know lol

:tt2: good to have you back on the forum.

 

lol
