hello all, I received a replacement clutch sprocket, the big one that holds the clutch pucks. I am trying to replace it. I got the small gear off with ease, but now I am stuck on removing the large one. How do I do it? Any picture would be nice. I screwed the clutch remover into the center hole using the big side. Then after doing the same procedure as with the smaller gear, it just pops off. Can't get it off been trying for 3 days now.
