Abstract
Dovetail-shaped grooves are formed in the axial faces and circumferential rims of wheels and spacers forming a rotor body. Complementary-shaped balance weights are inserted through entry apertures in the grooves and circumferentially aligned into adjusted balanced positions. Fasteners are threaded through the weights to engage in slots at circumferentially spaced positions along ribs projecting from the bases of the grooves. By threading the fastener into the slot and staking the fastener to the balance weight, the metal of the rotary component is not upset or deformed, with the result that the potential for development of cracks in the rotary component is substantially reduced.
