Are you sure you have to take it all apart? Anyways, take the variable speed line off. I usually then remove those outer bolts you see that hold that hydraulic plunger in and remove it. Then you will see two bolts directly opposite of each other on the outer sheave. Take one out, make sure flat washer comes with. Drive that pin out then you can remove that outer sheave. Inside the inner sheave there is a lock nut, can't remember size of nut off the top of my head. Ideally you would use a larger impact 3/4 to 1" drive, but if you don't have you can engage seperator drive and try getting it off without an impact. Once you get that locknut off you will need some kind of puller assembly to get the inner sheave off the shaft as the shaft is tapered. I have made on that goes through the slots
you will see. That inner sheave is heavier than the outer one so don't drop that one on your toes. When you put it back together you want to make sure that is tight, if it isn't you will wear the splines prematurely.
