EC290 D7E TCD2013 L06 2V Front cover 20875082 04507272

When the EC290 D7E engine is running, the driving gear on the camshaft will drive the transmission gear of the 20875082 oil pump, so that the driving gear fixed on the driving gear shaft will rotate, and drive the driven gear to rotate in the opposite direction, and then the oil will pass through the oil inlet cavity. It is transported out of the oil cavity along the tooth gap and the pump wall. At this time, a certain suction effect will be formed at the oil inlet cavity, and in conjunction with the rotation of the main and driven gears, the oil pressure will be sent to the surface of each part of the D7E engine.
