    Replace pump.... not usually fixable for that flaw.

    I'm starting the disassembly. I figure since I'm going to replace the seal I should replace the bearing too. Does thet sound like a good idea?

    All I will need is the seal, clip, and bearing, right? Can I order these parts separately?

    I have my bearing puller setup on the shaft. Does this look correct? I am concerned that the brass housing will not withstand the lateral force of the puller.

    Do I need to remove the little clip inside the seal before I push the shaft out?

    I've uploaded some pictures.

    If the shaft is scored, replacing the seal will be futile.

    The bearing seems tight and like new, so I decided to just replace the seal. The shaft seems to be smooth. The seal is visibly worn from the shaft spinning in it over time. Now I just need to find a new seal and do a pressure test to see if this solved the problem.Click image for larger version.

    That is not the opinion he wanted to hear.
    Bob, you are correct. These pumps are crap and when they leak you replace them. His repair will fail.
