Ok if you never had a primary clutch apart there are some things to know.First mark the top cover ,spider ,movable sheave and stationary sheave with a dot or X.These things need to line back up when you reassemble.If you are making tools then make your clutch holder to fit in a 2" truck receiver.You will need to use a torch to heat up the spider and burn the thread locker so you can remove the spider.You will need a 3' pipe to put on the breaker bar.The torque for the spider is 250 ft.lbs jam nut 235 ft. lbs. Use red loctite to reassemble.Good luck.
