Trying to remove the primary cover on an 82 Ironhead and did remove the nut pictured. The Phillips seems to be moving with the case but something else is hanging up in that area. I did read the manual, it just says in order to change the clutch cable you need to remove the primary cover.
Forgive me, someone already told me they didn't think I needed to remove the Phillips screw. Going to do a search.

Okay, did a search and no luck with Iron's. I got it off with a little more than 'gentle' persuasion, after loosening the primary chain.
