Abstract
A method and system for re-indexing a pitch bearing of a wind turbine includes: installing a plurality of first mounts to the fixed outer race of the pitch bearing; positioning the rotor blade to a downwardly-oriented; installing a hydraulic system; pressurizing the hydraulic system so as to support the weight of the rotor blade with the hydraulic system; detaching the rotor blade from the pitch bearing; lowering the rotor blade a predetermined vertical distance from the hub; installing a plurality of second mounts to the rotor blade; attaching a plurality of supports between the first mounts and the second mounts; transferring the weight of the rotor blade from the hydraulic system to the plurality of supports; disengaging the hydraulic system; and re-indexing the pitch bearing so as to engage a new set of pitch bearing teeth.
