While replacing the oil pump, please clean up the wastes such as residues in the grease, iron filings. This will protect the oil pump and keep it from breaking for a long time. If wastes such as residues and iron filings are not cleaned up before replacement, the oil pump will suck in, which will cause the operation to stop, or even burn the oil pump in severe cases._x000D_ 2. When a new oil pump is installed for the first time, sometimes the oil pump makes a noise and does not supply oil due to the air in the pump core. At this time, the oil should be injected manually from the inlet of the oil pump when the power is turned on. Just help the air in the oil pump to discharge.
