Summary:A method 100 and system 30 for re-indexing a pitch bearing 40 of a wind turbine 10 includes: installing a plurality of first mounts 32 to the fixed outer race 42 of the pitch bearing 40; positioning the rotor blade 22 to a downwardly-oriented position; installing a hydraulic system 50; pressurizing the hydraulic system 50 so as to support the weight of the rotor blade 22 with the hydraulic system 50; detaching 105 the rotor blade 22 from the pitch bearing 40; lowering 106 the rotor blade 22 a predetermined vertical distance from the hub 20; installing a plurality of second mounts 60 to the rotor blade 22; attaching a plurality of supports 58 between the first mounts 32 and the second mounts 60; transferring the weight of the rotor blade 22 from the hydraulic system 50 to the plurality of supports 58; disengaging the hydraulic system 50; and re-indexing 111 the pitch bearing 40 so as to engage a new set of pitch bearing teeth.
