A hydrodynamic radial bearing including a cylindrical body having an inner wall and an outer wall, at least one gutter along the inner wall and at least one wedge-shaped recess in fluid receiving communication with the at last one gutter. The at least one wedge has a wide portion immediately adjacent the gutter and a narrow portion located away from the wide portion along the circumference of the inner wall. The bearing is manufactured by inserting the bearing into a fixture having at least one deforming protuberance located along an interior wall of the fixture so that the at least one protuberance contacts the outer wall of the bearing and elastically deforms the inner wall of the bearing. Then a machining operation is performed along the inner wall to remove the deformed portion of the inner wall. The bearing is then removed from the fixture and the machined portion of the wall retracts, forming at least one recess.

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