Description
Product Overview
The high-pressure oil pump is subjected to intense pressure of over 1,000 bar from the fuel, high-temperature cabin vibrations, and erosion by impurities in diesel fuel. The sealing surfaces of the internal control piston and分流 valve plates will develop scratches and wear. Various rubber seals will harden and leak. The pressure regulating spring will fatigue and lose its elasticity. Replacing the entire oil pump alone is costly. This set of repair kit covers all the wear-prone points of the high-pressure control components of the oil pump, pressure regulating spring, and multi-layer oil circuit sealing gaskets. After disassembling the high-pressure oil pump, the entire set of internal components can be replaced to repair the problems of fuel supply leakage and oil pressure instability. It is suitable for the maintenance of large mining excavators, heavy-duty loaders, and long-distance trucks with electronic common rail diesel engines.
Core advantages of the single product
Hardened alloy steel precision metal parts， mirror-polished， wear-resistant， and resistant to high-pressure erosion
The control piston，分流 valve plates， and limit steel balls are all made of quenched and tempered hardened alloy steel， with mirror-polished sealing working surfaces. Long-term high-pressure fuel erosion is unlikely to cause scratches， and it can maintain a micron-level precise sealing gap for a long time， preventing fuel leakage and rapid pressure loss in the rail.
Multi-level pressure regulating springs， with uniform and stable oil pressure output
The standard specifications of high-strength pressure regulating springs are provided， with uniform elastic parameters， and will not experience fatigue attenuation. They precisely regulate the basic oil pressure inside the oil pump and eliminate problems of insufficient oil pressure during heavy-load climbing and power breakdown.
Multi-color and multi-specification fluorine rubber sealing rings， with layered sealing to prevent leakage of air intake
Including black， blue， purple， and white multi-sized oil-resistant fluorine rubber O-rings， suitable for different oil circuit sealing grooves of the high-pressure oil pump. They are resistant to diesel soaking， have a wide range of high and low temperatures， and do not easily swell or harden. They provide multiple barriers against fuel leakage and air suction into the oil circuit.
Red plastic piston protection cap， protecting the precision valve core during storage and transportation
A red protective dust cap is provided， which is fitted on the end of the pressure regulating piston before assembly. It isolates dust， prevents damage to the valve core sealing surface from transportation impacts and scratches， and avoids valve core jamming and failure due to violent squeezing during disassembly.
The components of the set are uniformly sized and matched， eliminating the need for on-site grinding and adjustment
All metal precision parts and sealing gaskets are strictly controlled in tolerance， with standard sizes for the same model. After disassembling the oil pump， the entire set can be directly replaced without manual grinding and adjustment of the fitting clearance， significantly reducing the time for disassembling and repairing the oil pump.
Each set of repair kit undergoes factory calibration for flow rate， pressure， and pressure regulation response matching tests. After replacement， the oil pump builds pressure quickly， maintains stable rail pressure， and the engine power and idle smoothness recover rapidly.
