Claim 11:
12. A compressor comprising:
a shell;
a bearing housing fixed within the shell, the bearing housing including a central body and a plurality of arms extending radially outward from the central body, each of the arms having a first aperture;
a non-orbiting scroll including a plurality of second apertures;
an orbiting scroll supported on the bearing housing and meshingly engaged with the non-orbiting scroll;
a plurality of bushings each having a third aperture, each of the second apertures in the non-orbiting scroll receiving one of the bushings;
a plurality of fasteners rotatably securing the non-orbiting scroll relative to the bearing housing, each of the fasteners extending through the third aperture of a corresponding bushing and received in a corresponding one of the first apertures in the bearing housing; and
a plurality of first spacers, each of the first spacers received in the third aperture of a corresponding bushing and configured to engage one of the corresponding bushing and a corresponding fastener to restrict radial misalignment between a first longitudinal axis of the corresponding bushing and a second longitudinal axis of the corresponding fastener,
wherein a clearance gap is disposed radially between an inner diametrical surface of the corresponding bushing and a shaft of the corresponding fastener,
wherein each of the first spacers are disposed within the corresponding clearance gap, and
wherein the corresponding spacer and the corresponding clearance gap allow relative radial movement between the corresponding bushing and the corresponding fastener.
