Stuck how?

Does the stem bolt turn loose?

If so then loosen it and then twat it with a hammer to knock the angle clamp thingymajig down.

If you've done that and you know the bolt is loose and the angle clamp doodah is loose and its still stuck then make sure your handlebars are still on and turn them while locking the forks (with wheels) on between you firm thighs.   The stem should turn with this amount of leverage.   

If not then give the stem a tap (as in major thwack) with a rubber mallet.    Do the top and try sideways!!

If its still stuck then it looks like its rusted in and some idiot didn't grease it before installing.

Try the usual WD40 and diesel loosening methods.


This might be a risky method as I haven't put much thought into it.   It could cause futher wedginess!! 

If your forks have a big hole at the bottom then you could try removing the bolt and screwing it in from the bottom.

Screw it through the clamp doodah and give it a whack.    It will either loosen the stem or wedge it even further..............or do fook all!!

Another suggestion....................If the hole at the bottom of your forks is massive then the clamp doodah will fall out and maybe you could fit something UP your forks to whack the stem out!!


Thats it, I'm all out of ideas!!

Make sure your wheels, seat and bars are still on!!

Its far easier when your sat down, holding the front wheel and twisting the bars and whacking it off at the same time!!

Yep,cheers Moley ,all sorted now

next question is removing the cups from the crank housing? do i need a special tool(other than myself )

use a drift (bit like a long thick centre punch) and a hammer

Yeah hammer n drift for the bb and wiggle wiggle with the stem mate

Use an extension bar from a socket set and tap it out with a hammer.

The extension bar end will be slighty rounded so it wont damage the cups too much.  Dont use anything sharp like a screwdriver etc, etc.

When you reinstall everything..................use plenty of grease on everything apart from brake pads, rims and your seat and grips etc, etc   

Basically any metal on metal mechanical gubbins.  It will stop squeaking from components and it will make it easier to install and remove afterwards if you want to change anything.
