Hm...I seem to have extra parts trying to put my Axe back together...

I took out the main shaft and two rings came loose. It's either the collar or the bushing - not sure which. It's part number 30 and/or 25. *shrug* Their circumference is too big to fit inside the bearing and I'm not sure if it should be on top of the bearing or hang below. Anybody have any idea? Anybody have any idea what I'm talking about?
