Snap!

[J.M.]

Don't you just hate it when this happens...

Removed 7 successfully. 6 removed just the nuts. 1 removed the stud with the nut firmly attached. One snapped the stud.

What would be your preferred method to get this out? I will be attempting it tomorrow evening, probably around 6 or 7pm as to give it some extra soaking time.

At least now I can give the exhaust a good going over to get it all Chromed up and new looking. Will also get it properly welded up as to get rid of my bodgetastic repair that I did.

Edit: also how would you best clean up the remaining studs? Wire brush? Tap and die set?

Thats pretty shitty, really feel for you, hopefully some heat and mole grips will get em out, if not weld a nut onto it?

get 2 nuts on there if u can and impact wrench it out, otherwise as above said, weld a nut and get it off. Mole grips will just chew up the stud further!

Get a good pair of stilsons round it rather than mole grips.

The two nuts are my current favoured idea. There really isn't the room to be playing around with mole grips and I doubt their success in this scenario.

I don't have access to welding equipment, but in the worse case scenario I guess a bike shop does.

If it snaps again then I'll just drill it out and tap it. My neighbour helped us drill and tap the snapped stud on the GS500 motor. Though I would like it not to come to that.

Soak the bugger with repeated applications of proper penetrating oil for a couple of days before you attempt anything.

[iMark]

Oil, more oil and even more oil... then try the 2 nuts...

Plenty of WD-40 over night and Mole Grips worked for me but it fucked up the stud pretty bad.. but they got replaced anyway

Theres a little known products called "freeze & release"

It has a penetrating oil + freezes the thing you are attacking.. worked great the few times i've needed it.

I guess I have no immediate need to remove this stud. It will be at least a couple of days before I have the gaskets I need to rebuild the top end. A few more days soaking it is then.

Mr.Z, that "freeze & release" product looks too good to be true; it's making me sceptical! Is it really that effective?

Out of interest, now don't shoot me down too hard...

Could you put the exhausts back on with new studs where they have come out, where they haven't could you just put a locktight nut on the stud and tighten up? Or would that not work?

Nylock nuts have nylon inserts and exhausts get pretty hot...

Little concentric roller bearing type things inside that grip as you turn. It locks onto that un-threaded collar part of the stud.

They are a very handy bit of kit.

If you have ACF-50 then soak it in that, it worked a treat on mine. It's designed to wick into the tightest gaps and kill corrosion and is also a very good lubricant (better than WD-40)

[gavbriggs]

With the steel stud in an alu thread I was alway taught to 'shock' it with boiling water whilst putting pressure on by turning

It should work if you can get the hot water to pour slowly on the head???? Might want to block the ports with a rag or a carrier bag first though

I got a phone call from the small local garage at 1pm today (only took the head down this morning), saying that they had tried welding the stud to remove it but were simply unable to do it and I would have to take it to someone more specialised.

Dropped the head back off in my dad's garage on the way home. As I turned up tonight, I was greeted with this:

Should clarify, I wasn't expecting him to do anything to it. I'm just keeping my bike/bits in there whist I work on it as I have nowhere else safe (from kids or weather) to work on it.

Tomorrow is cleaning up and grabbing 2 new studs. Then it's pretty much on to the reassembly soon!

So what did he use / do to get the blighter out. Might be useful to know!

[Vincent]

JM, if you can get them, use deep-domed nuts on the new studs, they help to stop the studs rotting.
