Was fitting a new water flange that fits to the head and the bolt has snapped inside the head any ideas how the hell I'm going to get it out. Not sure why it snapped as only had the torque wrench set to specified 20nm.
Please help....
-
can you get molegrips on the end of the thread to turn it?
If not you could try a set of easy outs, but failing that your gonna have to dust off the old drill + tap and die set.
Cant think of another way off hand. soz :sad:
-
Tried mole grips but no gud and then made it so a flat head screwdriver would turn it and that snapped.... Yep am left with drilling I think problem is access is a bit tight and I aint used a tap and dies set before but looks like this could be the time. :cry:
-
do you mean the screw driver snapped or the bolt snapped more?
-
If you havnt used a tap and die set before you might want to take the head off and get a local engineiring firm to do it for you.
Can be very tricky if you drill it out on the p!ss.
:cool:
-
Yep the bolt snapped more.
Been and got some more small drill bits. Is already at a bit of an angle. Going to drill a hole if I can and then try an extractor set and if that don't work I'll be well narked. Deffo didn't want to get the head off. Thats just more hassle. arrrghhhh
-
lol hope it goes well mate!!!!
Keep us posted! :wink:
-
Will do mate fingers crossed and toes and everything else as if it don't work will have to think of something
-
im sure it'll work! when u trying it?
-
Today, problem is I already tried drilling and started going off centre so need to start again Might sand it down a bit so its flat and can start a fresh.
-
Remember to use left handed drill bits, I've had a 0% success rate at removing sheared off bits with screw type extraction tools, but best of luck!
-
WEll I've got a pilot hole drilled of to machine mart later to pick up a screw extractor and then finger crossed. What do you do with a left handed drill bit???
-
It cuts counter-clockwise instead of clockwise like normal drill bits, with the idea that whilst drilling a hole - it could also turn the stuck bolt out.
Whereas the normal drill bit, essentially tightens the stuck threads by turning it in further. Bear in mind stud extractors are very hard steel, therefore very brittle, if you snap that off, there's no chance to drill it out.
A lot of people stick a small weld and nut onto the end of the thread to turn it out.
-
Ches mate,
Am passed the welding a nut on bit although would have tried that if I'd have thought.
Can you get these left handed drill bits from anywhere B&Q etc/
-
What I'm about to suggest sounds seriously pikey, but stick with me....
Have you considered whacking a small stardrive into the sheared bolt? the shock could loosen the bolt a bit, and the stardrive is quite sharp and will bite into the bolt...
I just had to do this after rounding the allen head bolt on my crank sensor on my mk3....after taking the whole front of the car off to gain some room....
Sometimes you just need to get medievel.... :smiley:
-
lol that could well work! but if you snap the torx bit you are in a world of hurt as their toughened and bill be a b!tch to drill out!! :sad:
-
the shock could loosen the bolt a bit,
Apparently there is a freeze spray that can also shock the bolt.
-
lol that could well work! but if you snap the torx bit you are in a world of hurt as their toughened and bill be a b!tch to drill out!! :sad:
if you snap the torx drive you would need a carbide drill, plenty of cutting compound and even more patience!!
-
If you try an easyout, (stud extractor), do not go too big on the hole. As the easy out bites into the snapped bolt or stud, there is a risk of expanding the damaged bolt out even further thus 'locking' it into position. If this happens, then drill out the bolt as far as possible without going into the threads, then use a tap to clear out the remenants of the old bolt. You need to be very acurate with the drilling though.
-
Yep ended up having to tap a new hole...All back together now though and doesn't leak so thats good.
-
Nice one. :wink:
