Older threaded headset, the quill stem wont pull out?
? Peugeot PX, the headset is original, only difference I see is that instead of a hex bolt to run into the steerer\wedge it has a bolt with a nut on top instead of hex.
Well the bolts out, the stem turns in the headset but will not pull up and out.
Have I missed something? The hex bolt quill stems came out -is this possibly different.
It's soaking in wd-40, 2 guys pulling at it, I'm not so into the hammer method unless last resort.
Headset is original Peugeot stuff, not corroded.
Are there diff 'versions' of quill stem\headsets from France?
Thanks, my buddies bike so I'm less into the 'tough love' I'd do if he wasn't looking.

It could be wedged or corroded to such a degree that you'll have to put in a bolt, replacing the origional one, pound it down to loosen the assembly. Perhaps after the WD soaks in, you may be able to fish it out, but I bet it's the wedge binding the thing up. OHB

Not a wedge, flat round bolt, the old stem bottom end flat as well.
The bottom of the quill cylinder was cut 8 slots vertical 2 inches, the nut\wedge goes inside then flanges by forcing the tube slats outward.
Different fer sure, not seen by me before.
We're good to go, thanks.

I'm not sure of your location, but when I lived in the UK, I used "Plus Gas" releasing agent to help disassemble corroded exhaust systems. I used it recently to free a seized pedal (it had been assembled without grease, and the steel axle had seized to the aluminium crank arm). "Plus-Gas" dripped onto the thread and left for an hour or so worked wonderfully! Look around for an equivalent - good luck!

I can see why the industry went to the angled offset wedge.
No corrosion on the stem or inside tube. Bikes nice for 70's.

Is there a reason for this system? I guess it is a good strong mating.

Try this. Remove front wheel. Flip bike over. You should be able to use a long blade screwdriver and give it a moderate wack.The wedge looks like an exploded cork? I'd soak it with WD-40, and or Liquid Wrench.
