How to dismantle stem for a new one?

how do you take off the stem off a Fuji track bike?! there seems to be something unscrews at the top but then ???
would this two be switchable?

thanks a lot in advance as usual :)

looks like you have a 'quill' stem - so they should be swappable.. if the diameter is identical.

sizesw are either 1inch or 1 1/8inch (others are rare)

1 - undo the allen key at the top of the stem
2 - give it a little tap down to ensure that the expander wedge is free.
3 - slide out the stem straight up- done!

This looks like an OK guide to fitting the new one..

Normally I would point you to the PARK tools website, but they don't bother with this particular job..

Yes !

Give it a twist to loosen it up a little bit.

if i twist it, the fork/wheel moves... do i need to hold them in place? hurts the legs!!! :(

Put the front wheel between your legs and give the handle bars a sharp twist left and right, this should come out with a little force.

Two types:

if it's an expander type; unscrew the top bolt til it's sticking out about 1cm, then wack it with a hammer (not too hard), that forces the expander out the bottom of the stem - you should now be able to remove it.

if it's a wedge type, then it may have become stuck in there (they should come loose straight away). Turn it upside-down spray some Plus gas, WD40, etc, leave it over night, then try again.

this stem is cursed!! its locked in real tight!! :( almost fell from twisting :O

Do like Tris said, unscrew the bolt and when it is sticking around 1cm out of the top of the stem, give it a hit (downwards) with a hammer (or something like a rolling pin)

it looks like this now

i tried hitting it with rolling pin and twisting agian... nuttin

Did you hit the bolt (not the stem) ?

ROFL!! lemme get back to u!

dammit - no lcuk! i hit just below where the threads are!

Nah.. on the top of the stem.. not the headset!

FixAxioN please take a picture a bit wider, so we can show you where you should be hitting !

(it is on the very edge of both your pictures at the top)

you've unscrewed the locknut for the headset! use an allen key in the bolt at the very very very top of the stem! Good luck with getting that back together...

Should be hitting stem bolt.. not headset

having loosened it first of couse!

Take the cap off the top, undo, bang, twist

Where do you live? Somone save the bike!!! :)

ahhh!! i understand - lemme try again - just won the item LOL
