Abstract
A method and associated system are provided for removing a drive train component, such as a gearbox, from a rotor shaft uptower in a wind turbine, wherein the component is supported by transversely extending mounting arms at mount locations on the wind turbine frame. The drive train component is supported from above or below and the mount locations. At each mount location, a removal fixture is installed that includes an actuator that moves linearly essentially parallel to the rotor shaft. The mounting arms are simultaneously engaged with the respective actuators, which are controlled to linearly push the mounting arms until the drive train component disengages from the rotor shaft.
