Abstract: A system and method for lubricating a key shaft in a compaction machine is disclosed. The compaction machine may include a spline oil cavity and a key shaft in fluid communication with the spline oil cavity. The key shaft may include an axial splined portion and a helical splined portion on an outer surface thereof, a longitudinal lubricating passage extending through a substantial length of the key shaft and a plurality of additional lubricating passages intersecting the longitudinal lubricating passage. The system and method may additionally include lubricating the axial splined portion and the helical splined portion of the key shaft with the lubricating oil drawn from the spline oil cavity.

Abstract: A lubricating device in a pneumatic tool or the like, which device is tool mounted beyond an on-off or throttle valve and utilizes air pressure from within the tool to achieve a metering flow of stored lubricant. The device is installed for convenient servicing and includes a lubricant storage tank, a lubricant outlet, a wick means and an intermediate "ready" chamber. The latter receives lubricant from the storage tank and is pressurized in an open position of the throttle valve to induce a movement of lubricant through the wick means for exposure to flowing pressure fluid. Valving means are operative to control access of air from the ready chamber to the storage tank.
