Zusammenfassung:	A nacelle includes in turn a nacelle frame, and a yaw bearing having likewise/in turn at least a geared ring for providing a rotatable connection between the nacelle and the tower around a yaw axis. A method includes the steps of: a) disengaging the rotatable connection between the nacelle and the tower; b) lifting the nacelle from the tower by using lifting means, allowing the rotation of the geared ring; and c) rotating the geared ring around the yaw axis until the geared ring reaches a predetermined position with respect to the component to which the geared ring is connectable, either to the nacelle or the tower.
