Today I tried to take apart my headset to clean n grease it all up, my first time doing this job. Watched plenty of videos from YouTube seemed easy enough all came apart as it should but...... The steerer tube will not release from the frame. I've sprayed it with release spray, tapped it with a mallet and nothing!
It won't budge am I missing something a release clip etc??

Thanks in advance
Rich

Undo allen screw and remove cap top of the steerer tube. undo clamp bolts on stem, remove stem and handle bar assembly forks just drop out. some times need a bit of help with an Irish screwdriver but normally a doddle.

Yep done all of that got aggressive too! Tied the forks to the frame, loosely, just in case they shot out and gave the tube a beating with a hammer (block of wood on top of the tube)

Nothing........

Guessing it never got removed by the 1st owner

Mad

If possible try installing the stem and bars loose - (Without any spacers below the stem and without installing the top cap)

While sitting on the bike, lock the front brake and rock the bike forward and backward to get some play in the bottom headset bearing.

If you can get that "clunk" then you should then be OK to remove

Shocked Shocked Shocked


Bigger hammer then. Trouble is, there isn't anything solid on which to support the frame and hammer against is there, not without damaging tubes and paint. you cant even heat it up properly without damage, tricky...

Question on refitting a stem. How much overlap of the stem clamp is acceptable? I have a new stem with greater lift and angle, but it is much taller at the end where it connects to the steerer tube. The top Allen bolt is level with the top of the steerer but there is then another bit above the Allen key that is no longer touching the steerer. The bottom Allen bolt is fine as expected. The top cover still screws down.
Not sure if I'm happy with it, but it should be fine.
Famous last words!

2 to 2.5mm if I recall

Do you have any spacers below it and if so what size ?

I had the same problem recently swapping one Kore stem for another Kore stem, which was slightly taller.

To solve it, I replaced a 5mm spacer with a 2.5mm one

Three ok, could do just never really thought about it. Taking 1 of the spacers out or putting a Smaller 1 in would be the safer option and one I will look at. Don't know why I didn't think about the spacers, I suppose it's because I was trying too hard to lift the bars.
