1. A rotor bearing bushing assembly, comprising:
a substantially cylindrical bearing bushing comprising:
a spring recess extending inward from an outer surface of the bearing bushing;
an axial slot on the outer surface of the bearing bushing, wherein the axial slot intersects the spring recess; and
an inwardly stepped portion of the outer surface;
an anti-rotation tab configured to fit and extend axially in the axial slot, the anti-rotation tab being radially slidable within the axial slot;
a biasing element configured to fit in the spring recess and to push radially outward on the anti-rotation tab in the axial slot; and
a retention ring configured for interference fit on the outer surface of the stepped portion on the outer surface of the bearing bushing;
wherein:
the retention ring overlaps the axial slot and the anti-rotation tab; and
the retention ring is a solid ring, spanning a full circumference of the bearing bushing.
