Zusammenfassung:	A method for refurbishing a wind turbine 10 includes removing an existing machine head 120 from the wind turbine 10, and providing a new machine head 220 and an adapter 250. The new machine head 220 includes a base frame 222, and further includes a plurality of fastener holes 224 defined in the base frame 222. The adapter 250 includes an outer sidewall 252 and defines a first plurality of fastener holes 254 and a second plurality of fastener holes 256, the first plurality of fastener holes 254 disposed in a first hole pattern 255, the second plurality of fastener holes 256 disposed in a second hole pattern 257 different from the first hole pattern 255. The method further includes connecting the new machine head 220 and the adapter 250 such that the adapter 250 is connected to and between a yaw bearing 134, 234 and one of the base frame 222 or a top flange 112 of a tower 110 of the wind turbine 10.
