Thanks Gary for the reply.
I took photos as I started disassembly and unless it was wrong before I started then I have it back like it was. I’ll take another look at it though.
Mike I never seen one of those brass rings with only three bolts in it. Maybe that ring is off center? There should be a place where you can get four bolts in it. Also those bolts that hold that brass ring down are special. They have a shorter head. Check it out when you can!
