Pilot Pump and Pump for the Implement Oil Cooler (1) Pump for the implement oil cooler (2) Pilot pump | |
The pump for the pilot system and for oil cooling is a two-section gear pump. Pump (1) is the pump for the implement oil cooler. Pump (2) is the pump for the pilot supply and for the implement oil cooler.
The pilot pump and the pump for the implement oil cooler are mounted on the rear left side of the front pump drive. A drive shaft causes the pump drive to rotate when the engine is running. As the pump drive turns, the pilot pump and the pump for the implement oil cooler are rotated.
The pilot pump supplies pressure oil to the pilot system and the pilot pump circulates oil through the implement oil cooler. The pilot system has priority.
The pump for the implement oil cooler pulls hydraulic oil from the hydraulic tank. The pump circulates the hydraulic oil through the implement oil cooler.
