Check under images and you'll see what I mean.
Also how does the impeller look?
Sorry to rain on your parade.
bobodaclown said:Great. Hope the rest of things go well and no more hickups.
bobodaclown said:Check then length of the new screw with the old one, if the impeller is slipping. I think it will tighten down more cause its reverse threaded.
For the diffuser I'm not positive but think it only goes on one way. You've got to spin it till they all line up.
