Hot-Selling Fuel Injection Pump 3230F580T Common Rail Diesel Pump Engine Parts for Perkins/ Delphi

The importance of the high-pressure oil pump relative to the diesel engine determines the status of the high-pressure diesel pump. Once the high-pressure diesel pump fails, it will directly affect the working condition of the diesel engine. Therefore, when a diesel engine fails, the high-pressure diesel pump should be checked as soon as possible.

 The common causes of diesel engine high-pressure diesel pump failures are shared below:

1. The high-pressure diesel pump does not inject fuel;

2. The high-pressure diesel pump plunger is worn;

3. The oil outlet valve of the high-pressure diesel pump is damaged;

4. The high-pressure diesel pump sealing gasket is aging;

5. The hand-operated fuel transfer pump on the high-pressure fuel pump fails and no fuel is supplied;

6. The high-pressure diesel pump shaft is worn or broken;

7. The high-pressure fuel pump governor is damaged;

8. The injection pressure of the high-pressure diesel pump is abnormal;

9. Diesel enters the lubrication oil chamber of the high-pressure fuel pump;

10. The installation connection plate of the high-pressure diesel pump is loose and the injection angle changes;

11. The high-pressure diesel pump timing changes, deviates from the timing mark, and other faults.

What are the main contents of maintenance and adjustment of high-pressure diesel pump of diesel engine?

1. Check whether the pump body is leaking oil: Check whether the seals of the high-pressure fuel pump of the diesel engine, such as sealing gaskets, oil seals, etc., are damaged or aged. If they are damaged or aged, they should be replaced in time.

2. Check whether the parts inside the pump are worn: open the high-pressure oil pump and carefully check whether there are obvious signs of wear on the surface of each part of the pump. If so, replace the worn parts in time and ensure they are installed correctly.

3. Replace the pump sealing ring: Disassemble the high-pressure oil pump, disassemble the pump body, find and replace all the aging and hardened sealing rings.

  4. Check the speed governor: Before checking the speed governor, you must first confirm the flexibility of the oil supply gear rod movement and the wear of the bushing. Then go to the test bench to test whether the specified parameters are reached.
