I noticed when I rebuilt mine that someone had taken a punch or chisel to the threads. This was pretty common as a way to make sure they didnt come apart in the future. I had to file what I could and work that retainer back and forth with a punch and hammer to remove it. It was a pain in the @ss but I got it off eventually. I imagine you could use some sort of spanner wrench with the clutch gear stuffed in a vice.

Good luck, Jeff
