The rotor includes a spinner fixedly joined thereto for rotation therewith, with the spinner having an endwall disposed coaxially about a shaft for defining a balance plane. The mounting pin is disposed at the center of the endwall, with the endwall having a plurality of circumferentially spaced apart guide ribs defining a plurality of the guide slots between adjacent ones thereof. The balance weight is mounted on the spinner endwall, with the mounting aperture thereof receiving the mounting pin, and the guide tab being positioned in one of the guide slots for restraining circumferential movement thereof.
