Guys,

Any ideas on how to remove a stripped clutch cover bolt? Tried using a screw extractor but it snapped inside the bolt making things effectively worse..

The broken ez out is a problem what you can try is use a torx bit that is just smaller
than the head of bolt slightly larger than the drill bit you used, drive it into the bolt
head the points of the torx bit will cut into the bolt head. If the broken ez out dosn't
keep the bit from going in far enough then you can unscrew it with the stuck in the
bolt torx bit. Use a hammer and an extension on the torx bit to drive the bit into the
head of the bolt. Usually the grip from the 6 points of the hex bit will grab the bolt
and it will come out.

Drill off the head
Remove the cover
There will be enough of the headless screw showing to remove it with vice grips

6mm is .24"
so nothing bigger then that to start with.
Slightly larger than the inner diameter of the stripped head hold

Assuming that you have some basic knowledge....
If you do not have a good drill and drill bits, this can go south pretty fast.


I’ll give it a shot! What drill bit do you recommend?

Well, I have a cordless 24v drill with some gold drill bits. Hmm. I’d love to have it done professionally but I have no clue where to take it to. Maybe some auto garage?

That will work but if you have a T-40 torx bit try to drive it into the bolt
head and see if you can get enough purchase to unscrew it once you
drill more your committed to drilling the head off. I was just looking at
my bike and I don't think you will have enough left after drilling to get
it out. But you should be able to remove the case once the head is off
and then you will have no problem removing it. The only problem is going
to be that broken ez out.

Ugh, a simple clutch plate replacement turned into a nightmare..

I do have a t-40 but are you saying I should attach it to the drill and drill counter clockwise?

No what you want to do is drive the t-40 into the bolt head with a hammer works best
if you have an extension on the bit. You are trying to get the 6 points of the torx bit
to cut into the outside edge of the hole you made in the bolt head with the drill bit
so the t-40 will be stuck in the head of the striped bolt then by hand try to unscrew it.

Thank you everyone for your help! I was able to pick up a T35 bit and hammered it in and was able to extract the stripped bolt!

I knew you would get it it's always best to try the least destructive method
first. I have been using that method for years has not failed me yet. And
Ducati fastner's are some of the softest I have ever come across.

Glad to hear you successfully removed the offender. Given that the bolt was tight to begin with (problem #1), another method to bust it all out is to use an old-school impact driver. You could use the blade bit and just give it a good whack with a hammer. Once it's loose, just unscrew!
