D7D BFM1013 Front cover 20524412 04515832 04259226

20524412 is Oil pump ，also is front cover of BF6M1013 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 BF6M1013 engine is working, the driving gear on the camshaft drives the transmission gear of the 20524412 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.
