Well folks, I got it back together without splitting the tractor. The worst part was tapping the roll pins into place in the holes in the pressure plate housing. Very tedious tiny little love taps with a 6 OZ ball peen hammer. But all went well and the clutch release and engagement is right at the top of the throw. I had to push almost all the way down before to release the clutch, so those levers must have been cracked a long time. Thanks again Kenneth S and DJ54.
