Powermaster booster pump repair

Replace vanes, rotor and cam ring. This pump would run but made no pressure

pump parts come out the end after ring is removed

         Drilled a hole to get at an end of the wire ring

        wear plates, cam ring, and outlet only fit one way as they are keyed or pinned

       Vanes had worn enough that one got out and no pumping happened.

          going back together

Sometimes the wire snap ring can be reused, We used a snap ring on this one with some machine work
