you need the correct clutch puller ($35@ your dealer or if youre lucky like i was you can find someone here close to you to borrow one), it just screws into the threads in the clutch where the center bolt was pushing on the crank seperating the clutch from the crank, you have to wedge something in the clutch (breakerbar, pipe, wood) to hold it from spinning, some are real stubborn, you may need to heat it up or try packing some grease into the center whole for some extra hydraulic help
