I got the rebuild kit for my 20+ year old 2 HP single-speed Max-E-Glas pump. I got the square gasket replaced by the strainer basket. I am working on getting the impeller out (it is locked onto the shaft pretty tight)
I found this brass ring around the impeller body - I don't see it in the parts diagram from Pentair. Also you can see in the photo of the impeller - it looks like some of the plastic has been chewed away. The brass ring is loose. So what does the ring do, and do I need to replace the impeller?
