Abstract: A method is provided for re-indexing a pitch bearing configured with a rotor blade of a wind turbine. A hoisting system is anchored within the rotor hub and includes a plurality of support elements connected to a drive system. The support elements are connected to the root flange of the rotor blade, and the rotor hub is rotated so that the rotor blade is in a vertical six o'clock position. The root flange is disconnected from the inner race such that the rotor blade is fully supported by the hoisting system. With the hoisting system, the rotor blade is lowered a predetermined distance from the hub and the pitch bearing is re-indexed to a position so as to engage a new set of pitch bearing teeth with a pitch drive that engages the pitch bearing.
