The auxiliary cam plate is configured to be coupled a rotatable shaft (114). A central shaft opening (308) extends through the auxiliary cam plate. A plurality of piston openings (312) surround the central opening and extend through the auxiliary cam plate. A circumferential cut (404) is formed in and extends around the outer peripheral surface (306) of the auxiliary cam plate. The auxiliary cam retainer has a plurality of ramps (614) formed therein, and each ramp slopes upwardly from a first end to a second end. A plurality of substantially flat pads (616) are disposed between each of the ramps, and each pad extends between the first end of one ramp and the second end of another ramp.
