Should just slide out after everything is removed, unless there is corrosion or it's bent. Which could be the reason why it's not working smoothly in the first place.

Make sure you deburr the thread holes for the butterfly screws BEFORE trying to pull the shafts out. Otherwise you will score the bores and it will vacuum leak.
When you put the shafts back in, assemble the butterflies to the shafts lightly then hold up to a light and check for proper alignment. Once butterflys are seated correctly tighten and stake the screws.
