oh ok. you had me going there!
here's a trick when removing the clutch cover. slightly loosen the clutch cover bolts, hold the cover in place and lightly tap the perimeter of the clutch cover. in most cases this will allow you to remove the cover with the o-ring in the cover. this can save a lot of time when reinstalling. for those who have installed the clutch cover gasket you know what i'm talking about.
