Oh an to answer your q, flip over the quick release to loosen it. There should now be a gap between the stem and head of qr. Tap down on the head of the qr to dislodge to wedge nut inside.

If you can’t get wedge nut to budge, unscrew the qr completely and pull out the stem. Then use rods and tools and monkey strength to get it to budge. (Maybe even evaporust, if you got it)

After you have made sure that the wedge nut has been losened (by hammering on the screw) and it is still stuck, you can try to use the handlebars to turn it left and right (while fixating the wheel with your legs) to try and losen it. Be careful though if your stem is in a bad shape. Last time I had this isse the handlebar clamp part of the stem disintegrated and I held the handlebars in my hands while the rest of the stem was still stuck. In the end I managed to hammer it out but it's better to just twist it upwards.

This! Except there is no head, Its a different kind of screw you can take out.

As i understand i take D out of the entire thing. Amazing that you found this pic, Aside from the screw thats EXACTLY the kind of rod that is used.

Might still be clamped. Check if it is possible to screw back in or take a flashlight and look into the fork. If it is still there you need to screw back in and give a tap with a hammer. If no more wedge nut just wiggle the handlebars

>how to get it out?
If the wedge actually fell down then it's not holding the stem in anymore. You can remove the stem. Then remove the wedge.
If it is still there, you need to re-thread the bolt back in some and then knock it down, to release the stem. Make sure the bolt has a reasonable purchase or you will damage the threads.

Lubricant will not help if the body of the stem is actually badly stuck because it will not penetrate the corrosion.

instead then you just use force. Once you're using enough force to possibly bend your fork or wheel or bars consider plugging the stem, upside down, and soaking it in white vinegar. That actually will do something to galvanic corrosion. Wd40 won't.

take this as a lesson to buy a tub of grease, and routinely clean/grease mating parts, and grease threads.

so is the corrosion surely galvanic? i thought that was a consequence of a differential in the electric natures of dissimilar metals...

sorry you're not op

all the really badly stuck stems and seatposts i've ever encountered have been aluminium in a steel frame and yeah it's galvanic corrosion.
according to brandt and i think he's right from trying it fruitlessly penetrating lube does nothing to galvanic corrosion.
