Ok so I have took the old plates out and I put the new ones in but the clutch pushes to far out, in other words its all most like the clutch in pulled full. I have looked at the outer clutch cover or hub and I can see that it is worn about 2mm's. Is this normal?

If I keep the Fiction plate with the rubber dumpers in but put the worn plates back it works and the clutch doesnt slip for now.

What am I doing wrong, do I need a new outer cover, any ideas?
