When you swing your arm back and forth you are swinging the throw out bearing off of the pressure plate and then back on. When you hit the pressure plate it feels like a solid block because the arm would move 1 1/8" for the entire throw of the clutch pedal. No you can't move it by hand and no you can't move it with a wrench on it.
What you are seeing is normal and doesn't indicate you put anything together wrong. It doesn't necessarily indicate you put it all together right, but it does NOT mean you put it together wrong.
Semi-common question on this forum btw.http://www.fiero.nl/forum/A...030819-2-033780.html
