Great video. Question, looking at your video it appeared that the surface of the cover that the oil rotors spin against had some amount of galling on them. Is it typical that you have some galling and how much is ok? You seem to have lots of experience with these pumps. This is my first rebuild and not sure if i need to be buying new housings or not as I have some galling.
Yes that was an example of a used one. You will pretty much always see come galling on the covers as well as in the housings. It really depends on how much scoring and how deep it is. If in doubt always buy new covers and rotors/outter rotors (if they are scored up). They are not very expensive and it is cheap insurance.
