Clutch CRIMAZ CMX Race

Hi! Can someone explain to me how to mount the Crimaz clutch to the engine! I do not understand how it will be done from the text on the website " This means that the heavy assembled clutch basket no longer rotates on the crankshaft. Instead it is attached to the input shaft through the cog found on the primary-drive, the lighter inner basket is then attached to the crankshaft instead. " I

Am i suposed to attach the clutch to the primary drive?! ....I don't understand a thing! Maybe some pictures could help

Thanks in advance! / Jonas
