Abstract
A method to repair a rotor system having a coupling, a coupling keyway, a shaft, a shaft keyway, and a key. The method may include the steps of machining a shaft relief on the shaft adjacent to the coupling, providing fillet radii to the coupling keyway and the shaft keyway, adding a fretting resistant button to the key, machining a keyway relief on the shaft keyway, and machining a coupling relief on the coupling adjacent to the shaft. The method further may include the step of machining the key, the step of positioning dowels between the coupling and the shaft, and the step of shot-peening the coupling keyway and the shaft keyway.
