Clutch Adjustment?

All arms are set evenly and have no funny marks or wear on them.The arms pivot on a roller or a pins.The throwout bearing does have a light mark on the front of it,all the way around.The mark is a scuff and you can't catch your finger nail on it.I used a fork return spring.
I noticed when I picked the pressure plate to look at it something rattled abit.On the pressure plate there are 3 groups of springs.4 in each group.In each group of springs there are 2 springs that have a roller,bushing,or some kind of spacer between the springs.So there are 3 of these one for each group of springs.Well one of these roller,bushings,or some kind of spacer is moving around abit.The other two are not.
Did I loose you yet? LOL I need to find a picture of a pressure plate all broken down to see what this part is and what it does?
