The present disclosure is directed to a system and methods for the service and exchange of a yaw bearing for a machine head of a wind turbine. The yaw bearing servicing and exchange system has a support stand. The support stand includes a base assembly and at least one support post extending perpendicularly from the base assembly. The support stand also includes at least one first post cap removably coupled to the support post and at least one leveler operably coupled to the at least one first post cap for establishing a level orientation of a support surface with respect to a horizontal plane.

A method for detaching or installing a rotor blade from or to a hub of a wind turbine includes positioning the rotor blade toward a ground location between a three o'clock position and a nine o'clock position. The method also includes mounting a mechanical arm to an uptower location of the wind turbine. Further, the mechanical arm includes a torqueing tool at a distal end thereof. Thus, the method also includes removing or installing, via the torqueing tool, each of the plurality of hub fasteners so as to detach or attach the rotor blade from or to the hub.
