A maintenance tool 50 and method for detaching mechanically-connected components 40 of a drive train in a wind turbine 10 is disclosed. The method involves positioning the maintenance tool 50 below a hoist and hoisting only the lift assembly portion 56 of the maintenance tool 50 into a nacelle 16 of a wind turbine 10; connecting the lift assembly portion 56 to a power source in the nacelle 16 and extending at least two induction cables 60 from an induction generator 58 disposed on the lift assembly portion 56 to wrap at least a portion of a component of the mechanically-connected components 40. Then operating the induction generator 58 to pass alternating current through the induction cables 60 and inductively heat the wrapped component such that thermal expansion creates a clearance between the mechanically-connected components 40 thereby assisting in separating the mechanically-connected components 40.
