I was replacing my sprocket on my MS261 and figured i would grease the cage bearing while i was at it. When i tried to remove the clutch drum it took a bit of a work and was slightly stuck on. When i got it off i noticed a bunch of residue along the outermost section all the way around. Do i just clean this off and put it back on there or do i have a bigger issue and need to replace more? See pic below for the residue
