I don't have a picture of mine but I'll try to put something out there.
In this one, it is the larger threaded thing on the crank. In the picture, it is about 1/2 way over the left hand threads that hold the clutch on. It is threaded OD and turns on the crank freely. Mine won't thread or slip over the LH threads at all. I think it was either put on before the crank was pinned, or it is buggered up on the ID and won't come off like it is supposed to. It was a HF refirb, I bought it and took it apart well over a year ago. Just came around on the "things to do" (again) the other day. I think if I cut the crank with the sleeve slid all the way on, I can pull it off and cut it again closer to the case. If I slide it all the way out, there isn't enough room between it and the seal to get a whizzy disk in there. It won't come out, over the threads, as far as the one above. I hate to pry or force it out more to get behind it. Unless I am missing something. Thanks, MIKE
