Diesel Injector Fuel Injector 0445110255 Common Rail Injector

If the needle valve and valve body of the fuel injector are not tightly sealed, mutually seized or oil dripping occurs, the fuel injector should be removed first and the needle valve and valve body should be cleaned with clean diesel oil. If the sealing cone between the needle valve and the valve body When there are slight pits and pits, they should be ground on special equipment or pliers (note that the grinding paste must not enter the sliding surface between the needle valve and the valve body), and then grind with oil until the needle valve and the valve body When the pits and pits on the sealing cone surface disappear and become black and bright, for the injectors that are stuck between the needle valve and the valve body, first take out the needle valve with criss pliers, and then put it in clean diesel oil for cleaning Clean, and then use a relatively fine oil stone or sand bar to smooth the stuck protrusion (note that other parts must not be worn), so that the needle valve can slide freely in the valve body, and then use grinding paste and engine oil to seal the cone surface. Grind to the above requirements. If there are many pits and pits on the sealing cone surface between the needle valve and the valve body and cannot be repaired, replace the injector with a new one and adjust the fuel injection pressure and fuel atomization quality on the test bench or vehicle to make sure To meet the requirements of use
