stuck tuf neck stem

[kjilaja]

You only need to undo the top (smaller) bolt to remove the stem, if you can undo the bolt and the stem still won't move give the top of the bolt a tap with a hammer, the wedge could be stuck in the forks

If you can't undo the bolt stick the bike upside down and squirt WD40 down the steerer tube and let it soak for a while

I've tried squirting wd40 down the tube and it's still not budging.the smaller stem bolt seems to be stuck to the bigger bolt underneath,and the more I try and loosen it the edges are starting to round so now the spanner won't even grab properly.desperately need this stem out as it's my fav haro bike and don't want to ruin it,cheers

Turn the bike upside down, then try inserting a suitable steel rod into the underside of the forks & twat it with a hefty hammer, forcing out the stem...

If it has a hollow stem bolt, plug it with something suitable, turn bike upside down, fill fork tube with diesel, leave overnight, empty out  decent set of locking mole grips on your now rounded bolt, should undo.

If its a solid stem bolt, no need to plug it.

good luck

WD40 isn't much use, I use red diesel.

If it is starting to round just say feck it and use vice grips as tight as you can get.

You need to be able to loosen the bolt attached to the wedge a few turns, once the bolt has risen 5-10mm tap it down to dislodge the wedge.

Once you've dislodged the wedge, hold the forks with a wheel between your knees and twist bars from side to side.

Cheers mothwasp that worked a treat,all I need to do now is get the wedge off the bolt,it's jammed on,I've sprayed it with wd40,hopefully this will work,thanks everyone else for there ideas.....

No problem mate, glad you removed it.
As for the stuck wedge, place the bolt in a vice extremely tight, then use mole grips (or anything similar) to turn the wedge. Obviously use appropriate lube to aid the process...!!
