Thanks dabba,
That answered 98% of my original question. I'm still a little concerned about the seeger ring being real loose. Maybe its fine because with the original plastic impeller it was kind of tight fitting and maybe because the jitsie impeller seems to have a little more lateral play. The ring turns freely on the shaft but if you move the impeller outward on the shaft it does lock it in. Maybe I'll order a new ring just to be sure. After doing some research on the ring its called a seeger grip ring. Its designed to be used on shafts that are not grooved, which is weird because a ours does have a shallow groove. It is the only ring they make that can be reused according to seeger-orbis the manufacturer.
