After the disassembly of the Cummins diesel generator oil delivery pump, check the wear of the inlet and outlet valves and valve seats: if there are cracks or severe wear, they should be replaced; If there is slight wear, it can be ground and repaired; If the piston and housing of the oil delivery pump are loose or move unevenly due to wear, the pump should be replaced with a new one.


If there are signs of wear, dents, pits, etc. on the plane of the one-way valve, grinding paste should be used to grind it on the flat plate. In severe cases, a new one should be replaced. The surface of the one-way valve seat on the housing is severely worn or uneven, which should be replaced. If the top rod and top rod sleeve are severely worn, resulting in large gaps, poor sealing, and severe diesel leakage, they must be replaced together with the casing, or an oversized top rod must be selected, but mutual research is required.


The coarse filter core inside the oil inlet pipe joint is easily blocked by cotton like debris, which can affect fuel supply. Therefore, it is necessary to regularly pay attention to fuel cleaning and remove dirt from the filter core. When the rubber ring of the hand pump piston is damaged, it should be replaced in a timely manner. The oil leakage at the piston of the hand pump used in the 12 cylinder V-type diesel engine indicates wear on the mating surface and a large gap, which requires re selection.


After the reassembly of the Cummins diesel generator oil pump, it is required that the piston and top rod of the oil pump and other moving parts should move well throughout the entire stroke without any obstruction or jamming. The pressure pump should be lightweight and flexible, and attention should be paid to the installation of the one-way valve spring. The one-way valve spring must be accurately embedded in the spring groove.
