rebuilding my 200-4r yet again,got a bad intermediate band off ebay the anchor snapped right off >.<. anyway on tear down i noticed my direct drum had some wear on the slots the tangs of the sun shell engages,looks kinda bad to me but im not an expert.uploading a few pics of what i mean,two pics of the slots and one of the topside that seems to have a small ridge around the perimeter and slight scuffing/pitting on the bushing surface.im almost positive i could smooth them out but not sure if thats a wise idea or not,atleast for the bushing area.but yeah just some reassurance of oh its fine,clean it smooth it out and run it or a eww just buy a new one would be great =)
