D6E BF6M2012 oil pump front cover 21489736 04258382 04502445 04515825

21489736 is Oil pump ，also is front cover of D6D engine. It is gear type. The gear type oil pump structure, with excellent performance such as convenient processing, reliable work, long capacity, high pump oil pressure and large oil delivery.

When the D6D engine is working, the driving gear on the camshaft drives the transmission gear of the 04258382 oil pump, so that the driving gear fixed on the driving gear shaft rotates, thereby driving the driven gear to rotate in the opposite direction, and the oil is transferred from the oil inlet cavity along the backlash. It is sent to the oil outlet chamber with the pump wall. In this way, a low pressure is formed at the oil inlet cavity to generate suction, and the oil in the oil pan is sucked into the oil cavity. Due to the continuous rotation of the main and driven gears, the oil is continuously pressed to the required parts.
