A progressing cavity pump assembly having a collar assembly adapted to conne ct the housing and a tubing string, the collar having an inside diameter upset and the rotor having a rotor head axially spaced from a rotor helix, the rotor head having an outer diameter forming a stop, the stop adapted to land on the inside diameter upset. A method of timing a progressing cavity pump assembly including providing a collar assembly, the collar assembly having an inside diameter upset, movably connecting the collar assembly and the housing, providing a rotor having a rotor head axially spaced from a rotor helix, the rotor head having an outer diameter forming a stop, selectively adjusting the relative positio n of the collar assembly and the housing to form a pathway substantially corresponding to th e rotor helix, landing the stop on the inside diameter upset, and fixing the relative position of the collar assembly and the housing.
