Parts are galled together. Aluminum and stainless are really prone to galling but steel can too. You might try a heat gun and penetrating oil/liquid. On marine transmission I ran into this all the time. In the USA I use PBBlaster or Liquid Wrench. When you put steel and aluminum together anti-seize compound goes a long way.

There are frequent questions on how to remove parts frozen by time, but I haven't seen anything recently on pedal spindle threads frozen in cranks and
cannot find anything helpful in the archives.
I am very anxious to remove a pedal from a crank that I wish to preserve. I am not so worried about the pedal. The crank is aluminum and has a blanking plate (with small hole in its center) on the inboard end of the threaded hole in the crank. The pedal spindle is steel, presumably with some remnant of chrome plating. Is there a method of getting the pedal out that is reasonably sure of not causing damage to the crank or its threads?
Any help will be greatly appreciated and I will report back on its effectiveness.
