ABSTRACT:
A method of setting up the required running tolerances in a gerotor pump having annulus and rotor meshed together and located in a body comprises pressing a cover plate (FIG. 1) or equivalent as an interference fit into the body and then allowing it to relax and recover elastically to set up the required tolerances at axial ends of the gerotor set.
