I recently rebuilt a 8274 and was having a real difficult time getting the brake shaft drilled and tapped. 4 machine shops and 3 broken taps when my machinist buddy built me a nice split ring. He can make more if anyone is interested let me know figuring out numbers to get aluminum stock or stainless here is a pic if interested it would also allow use of a threaded bolt. Let me know if interested we can make a bunch.
