Causes of fuel injection pump plunger wear
The diesel used is neither filtered nor precipitated, so that the diesel contains more impurities.
The diesel filter does not work. Therefore, if the filter element is too dirty to be cleaned, replace it with a new one.
The diesel brand is not selected correctly. For example, diesel with too low viscosity is used when the temperature is high, or diesel with too high viscosity is used when the temperature is low, resulting in poor lubrication of the plunger and sleeve.
The plunger coupling (the combination of plunger and sleeve) is not vertically installed in the fuel injection pump body, which is also easy to wear. This phenomenon is mostly caused by the uneven gasket or the over tightened plunger sleeve set screw.
The fuel injection nozzle or outlet valve is stuck in the closed position. In this way, when the injection pressure of the fuel injector is too high, the plunger continues to pump oil, causing the plunger
