I’m replacing the clutch plates on my buddies 98 softail custom and was wondering if it was necessary to loosen the clutch hub main shaft nut, after I remove the adjuster screw? I watched a video where someone loosened it but he also replaced the primary chain. just want to make sure I do it correctly.

 

You don`t need to remove the clutch hub retaining nut.

Your friend, however, needs to buy a Factory Service Manual (not haynes, not chiltons...Genuine Harley Davidson).
