All clutch plates have a wave spring between the friction materials. This allows for a slightly smoother engagement. Some also have too much wave in the spring, spreading the friction material to far apart reducing the clearance between the flywheel and the pressure plate. There is always some clutch break-in required with new clutches to get the fuzzys off. Some times just letting it set for a few days, will let things compress and it will work just fine. Hope it does not have to come back apart. Good luck.

The older I get, I only want to work on older rigs.
