Removing a rounded stem bolt.

<< < (2/3) > >>

Rombloke:
if you dont wanna try and save the bolt, (which in fairness looks shot), then just drill the head of the bolt off.

once this is done, the stem will be free, and you should be able to (as dave says) knock the wedge out from the underside of the forks

ok?

Tried a few different things including soaking in WD40, mole grips, cutting a notch and using a screwdriver.....

nothing worked it would budge.

My drill wa srubbish too and wouldnt even mark it.

So I decide to go with the suggestion of my local bike mechanic and SAW the whole head off!!!

It took effin ages to do and made a mess of the stem thats for sure (gonna need some serious buffing)

And guess what?

The bolt was COUNTERSUNK!!!

The las time I undid a stem like this I was 14 or so so I didnt remember this, it certainly didnt look countersunk.

But now it just seems pretty fooked, theres a large part of the very strong steel bolt head recessed into the stem - definteley wont "drop out", theres no way to  grip it now obviously either.

Any ideas to for rescuing this disaster?
