What gun and tip?

@@TheAagaards Weller 100/140 watt with the plastic cutting tip.

nice to know, thanks

if i have to cut it out i use a die grinder with a wood type cutting blade, it removes alot of plastic fast, i typically cut a x pattern in the the ring then wedge a cheapo long flat head screw driver to pry it and fold it inward.

yessir, this is how i do it, freeze the housing with impeller removed and new wear ring, the old one will simple punch out and the new one will slide in pretty easy, if your stressed on time then i cut the old one out and use a shop press and grease to press the new ring in

I did that, still needed the press….
