I need to change the clutch hub on my '96 sportster. Yes I have a manual but is says something about removing a clip behind the hub and I can't even see that. I know I need to take the left hand thread nut off. Do I have to use a puller to slide the hub off the shaft? Will the clutch shell come with it? I read somewhere I'll need a press, what for? Please tell me how to get this off, I'm to po' to put it in the shop. Thanks
