A maintenance tool and method for detaching mechanically-connected components of a drive train in a wind turbine is disclosed. The method involves positioning the maintenance tool below a hoist and hoisting only the lift assembly portion of the maintenance tool into a nacelle of a wind turbine. Connecting the lift assembly portion to a power source in the nacelle and extending at least two induction cables from an induction generator disposed on the lift assembly portion to wrap at least a portion of a component of the mechanically-connected components. Then operating the induction generator to pass alternating current through the induction cables and inductively heat the wrapped component such that thermal expansion creates a clearance between the mechanically-connected components thereby assisting in separating the mechanically-connected components.
