The gearbox in a wind turbine does not "change gears". It normally has a single gear ratio between the rotation of the rotor and the generator. For a 600 or 750 kW machine, the gear ratio is typically approximately 1 to 50. The picture below shows a MW gearbox for a wind turbine. This particular gearbox is somewhat unusual, since it has ...
Remove the nut on top of the windmill helmet. Be careful not to drop the nut or washers as you remove the cover. Remove the drain plug on the front of the gear box and drain the oil into a proper container. If you notice water in the used oil, locate the source of the water penetration. Fill the gear box with a solvent to flush containments if ...

One was the annual "Windmill gearbox oil changes", (my dad had 0 tolerance for wimps)! The rope tied to my belt wasn''t for safety, it was to pull up the tools and supplies I needed after I was at the top. We used 30 weight gear oil. I would look into a synthetic mid weight gear oil, ask your auto parts guy.
