GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
I noticed that the parts catalog lists housing and seal, but didn't find one. There was residue from some kind of brittle sealant under the wear plate.
Housing and seal means the impeller housing and the shaft seal in the top of it. No gaskets except some sort of gasket sealer under the plate--whatever you have on hand.
