Sump bolt sheared

[carvern]

Time to change the oil, simple job, I thought. Had already purchased a new sump plug bolt, so drained oil changed filter and time to screw in new bolt and Snap! Head sheared straight off. Left with the thread inside the sump pan and the head in my hand. No way am I drilling it out can't get the bike up high enough to get a drill to it anyway. Managed to screw the head back in slightly and slapped some liquid steel around it.

What a  knightmare.

Good idea not to give it too much welly  when doing up the new one.. Torque it  up? 

[Burchy]

Might be worth getting one of those 90 degree transfer boxes that go on a drill.  Push the bike up onto a plank and park on the prop stand this will give you a lot more room to play with underneath.

Don't think I'd be happy riding around with a bit of glue holding all the oil in 

Beggars the question .  Why did you happen to have a new sump bolt handy?

[carvern]

Very aware not to tighten to much, I think in fact they are designed to shear of if torqued too much so as not to strip the thread, but what you do after its left in there I'm not quite sure?

[carvern]

The thread part of the bolt is probably about 5mm up the thread of the sump so don't think there is any chance of it coming out, plus the bolt head is half a turn up the thread with liquid steel holding it in place.

[Bryn]

If the head has sheared off can we assume the thread thats left in there isn't in too tight? If not once the metal glue stuff goes off perhaps it will undo....

Wouldn't use it until I'd got it out... Not worth a new engine 

[carvern]

Got underneath and tried to move the thread that was in there, but it wouldn't budge so guess it not going to come out.

[Bryn]

How about sidestand, fine drill, about 4 mm to make a small hole.. Then tap a torx bit into the hole ....

[O.C.]

Engine drain bolt torque setting is 30 nm or 22 ftl b great care should be taken not to exceed this figure

I suggest you drill out the damaged plug and replace it with a new one   

[carvern]

Only thought I had with drilling it out is wouldn't the action of the drill screw it further in and possibly through into the sump?

[Burchy]

As long as you drill at a decently fast speed and let the bit do the work, the old threaded bit won't move.  Just don't lean too heavily on the drill and you'll soon have a decent hole

This sounds like its going to get very messy!

No ....not if you pilot drill it first and then use a Bolt extraction tool...like this 

If you don't feel confident in doing it yourself then I would suggest that you approach someone who is ...no offence

Play it safe, very safe, get it to the dealer or get them to collect it and let them sort it. Probably cost you an hours labour, £60-£70 but could be worth it in the long run.

I agree with the Wolf
Wouldn't chance it until it's fixed, which it needs to be sooner or later anyway for the next change of oil
