Dongle Squares Posted March 31 Report Share Posted March 31 So I have a couple marathon pumps I'm trying to fix up... I have the correct impellers and they match the original. My issue is the shaft seal. I have ordered like 4 different variety of shaft seal and literally none of them fit this thing. I'm at a total loss, I've never experienced this before . Picture of impeller attached to post. Also impeller pn- 35-605-1000 CMP wet end 3.0 hp Basically the impeller shaft seal fits all the way up until the lip on the shaft where it expands out wider. Any ideas? Quote Link to comment Share on other sites More sharing options...
