Zusammenfassung:	An excavator comprises an upper unit rotatably mounted on an undercarriage by selectively driving a swing pinion gear against a reaction ring gear secured to the undercarriage. An enclosure, comprising a pan having a cover secured thereon, forms an annular chamber containing the swing pinion and ring gear therein. A pair of wedge-like members, secured to the cover, are disposed on either side of the swing pinion to continuously press grease into meshing teeth of the respective gears.
