11 A spacer (70) of a desired thickness sets the clearance between an end face (20) of a fluid displacement device rotor and an end plate (24) of a fluid displacement device housing. Initially the spacer (70) is located on either the end face (20) or the end plate (24). The end face (20) is then positioned adjacent said end plate (24). Next, the rotor is axially displaced relative to the housing to a desired position wherein the spacer (70) is in contact with both the end face (20) and the end plate (24). Finally, the rotor is secured in said desired position.
