It was a while ago. I think I machined up a sleeve out of stainless steel for the ceramic half to have a snug fit into the impeller . The ceramic half will stay put in the impeller ( not spin ) because it is held in place under tension from the spring and the neoprene surround sleeve will help it to grip . Yes the ceramic ring is a loose fit on the shaft . Look at my post with the pics.
