Therefore, the assembly should be carefully installed, do not bump the plunger, and the plunger pair of parts cleaned to prevent impurities into the plunger pair. 3, the sleeve set screw is too long If the plunger sleeve set screw is too long or install the set screw forget the washer, the sleeve will be top dead, the sleeve deviation, resulting in the plunger card. If the positioning screw is too long, the appropriate amount of file short, do not forget to install the washer washer when positioning the screw. 4, the pump base uneven Because the pump body to install the plunger sleeve shoulder uneven base or dirt, affecting the assembly accuracy of the sleeve, the pump plunger assembly deflection, resulting in the plunger card. Check the uneven pump method is to pull the fuel pump from the body, connected to the low-pressure oil circuit and open the fuel tank switch, so that the pump body is full of diesel, and the fuel pump external wipe clean. Found at the wheel at the oil leakage, indicating uneven pump base, resulting in diesel seepage, available an old plunger sleeve, coated with abrasive sand at the shoulder, into the pump body, kept rotating and knocking the sleeve Grind, flatten and refill and check for leaks. 5, the new piston pair storage time is too long The new plunger pair is too long, easily lead to oil loss and oxidation reaction, so that the plunger rusty, unwashed on the assembly, work caused by the plunger card.
