Drilling Out Sump Plug?

[UlsterSV]

Good folk of sv650.org, how is this done? Can it be done using a bog standard drill bit? I've managed to round the sump plug. It's royally fooked. I drilled right through the head and used an allen key to try to undo it, but to no avail. So now I'm left with a very round plug with a very big bloody hole through it. Is there any way of drilling it out? Or any other way I could try to undo it? I have a couple of bits that are meant to drill out rounded bolts but the tips are very flat so I don't know how they are meant to work :?

Any advice is very much appreciated!!

weld a nut the the plug and undo it with that.

:) Hi there!
What we do if we get prob's like this on cars,is to either get some mole-grips on it,or if you've already drilled through it,and you have any Spline type tools,try and bash one up through the hole,and then undo it! I know this sounds like a real bodge,BUT Ford Ka's spark-plugs shear off in the cylinder head,and this is the only way to get the remains of the 'plug out without removing the Head!
Good Luck! :)

Try a set of plumbers pipe wrenches,always works on stubborn nuts for me :)

you can get stud exstractors which you tap in and then use a spanner to undo also try lightly i mean lightly so as not to damage the threads tapping it with a hammer to loosen it first

I wouldn't use an extractor, if there's anything left to grip, and with a rounded bolt head there is, then pipe grips or mole grips or similar is by far the best solution.

Ok, thanks all. Will try the mole grips or pipe grips this weekend and see how I go. And if they don't work, I think I'll have to resort to this ](*,)

I've a set of these (http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=102089&ts=64544&id=96028) and they are very good, a useful investment.

Cheers Mark.

Interesting looking devices sir, I might just grab a set.


I keep hearing horror stories of Suzuki bolts being made of cheese. Whenever I get the opportunity I replace any I remove with Stainless Socket headed bolts. However, I have never felt the need to change the oil drain plug.

I have to question why I read of drain plug problems. They should never be torqued that tight as to make removal a problem. Perhaps investment in a set of decent flank drive sockets should be a pre requisite for any home mechanic.

Don't use a spanner with stud extractors, you are asking for it to snap, use a tap wrench, that is why the have a square head

indeed, the only reason I can think of is the fact it's upsidedown, so people tighten it up by mistake first?
