Received my replacement cover and bearings for Bearingate, when I went to replace it this afternoon, the bolt that holds the flywheel / hobbed bolt in place (which consistently unwinds itself), came out caked with black gunk and appeared to have been worn down. This was after wiping it down quite a bit: https://photos.app.goo.gl/Zfvo0mZH0pQ5ovwG2 I'm assuming the flywheel is grinding away? I tried not to tighten the bolt too much, but it then comes undone and I come back and it is almost falling out. Do I just need a replacement flywheel? When putting everything back together, I swapped this one with one of the other long ones, but that might just grind away further.
