A method for refurbishing a wind turbine includes positioning a new tower support mount on an existing foundation of the wind turbine, the existing foundation including an existing foundation pad and an existing tower support mount at least partially embedded in the existing foundation pad. The method further includes inserting a plurality of anchors through the new tower support mount.

Methods and apparatus for refurbishing wind turbine foundations

A system for lubricating gears includes a drive pinion configured to interact with bearing teeth. The drive pinion includes an internal axially extending lubricant channel connected to a plurality of radially extending lubricant delivery conduits. The plurality of radially extending lubricant delivery conduits extend from the internal axially extending lubricant channel radially outward to a radial surface of the drive pinion. The system is configured to transport lubricant from the internal lubricant channel through the plurality of lubricant delivery conduits to the radial surface to lubricate the drive pinion and the bearing teeth.
