The oil pump is located in the crankcase. The power of the gear pump, depending on the characteristics of the engine, is different. The oil pump is equipped with a pressure reducing valve that limits the pressure to 5 bar. The suction pipe of the oil pump is immersed in an oil bath (crankcase). Oil flows from the oil pump to the filter. At full throttle, more than 30 liters of oil per minute passes through the pump.
