the clutch is held in place by one nut, but its a bit hard to take it off with regular tools. you will need to hold the plate in place(or have someone else do it for you) while you use a power tool to crack open the nut. after you take it off, be careful not to loose any shims or other parts from the back of it, and make sure they go back on in the same order. thats pretty much it.
