PB Blaster is a better penetrate than WD-40. Or soak it in ATF. After soaking some, try and work the shafts back and forth. If that doesn't work. Remove the butterflies and knock the shafts out.

Make sure that you mark the butterflies before removing them. Also, you have to file/grind the peening over of the butterflies screws to make the removal. Make sure you peen them over after reinstalling [ask me how I know !!!].
