1. A planetary sun gear lubricant system for planetary gear set comprising a sun gear having peripheral teeth, plural planet gears supported by a carrier, and a ring gear all located in a housing which acts as a sump for a lubricant, said carrier being mounted for rotation in said housing and having circumferentially spaced apart axially extending spacer members having inner and outer surfaces, the improvement comprising:

  • at least one of said spacer members having a passageway extending from the outer surface of said spacer to the inner surface of said spacer, the inner end of said passageway being directed toward the teeth of said sun gear,said one of said spacer members on the outer periphery thereof having a deflector mounted thereon adjacent to the outer end of said passageway, said deflector being angled to the direction of rotation of said carrier,said deflector being in fluid communication with said passageway whereby rotary movement of the carrier supported deflector through the lubricant within the housing causing inward deflection of the lubricant through the passageway to the teeth of said sun gear.
