A bidirectional lubrication is provided for the shaft journal bearing of a reversible hydraulic gear device of the type having a journal bearing disposed in the commutator of the pump. A pair of lubrication ports on opposite sides of the journal bearing are connected to the inlet/outlet and outlet/inlet portions of the commutator to provide a flow of lubrication and cooling fluid across the bearing regardless of which direction the pump is operating. |
