Description
Product Overview
Under long-term operation conditions at the construction site, such as 24-hour heavy load, high-temperature vibration in the engine compartment, and impurities from diesel washing the components, various rubber seals will harden and crack, metal gaskets will fatigue and deform, and oil passage filters will get clogged. As a result, problems such as main shaft leakage, internal leakage of high-pressure fuel, slow pressure building, difficulty in cold start, continuous power loss, and dilution of engine oil by fuel will occur. This complete maintenance package covers all sealing, fastening, and filtering components of the pump cover, main shaft chamber, high-pressure outlet, metering valve, and low-pressure oil passage of the CP3 series oil pump. During major overhauls, all worn-out components are replaced at once, significantly extending the service life of the oil pump as a whole. It is suitable for maintenance of CP3 common rail oil pumps for small and medium-sized excavators, heavy-duty trucks, and agricultural large machinery.
Core advantages of the package
Full-size multi-specification oil-resistant O-rings, covering all oil passage sealing points
Multiple inner diameters and multiple line diameters black oil-resistant rubber sealing rings, suitable for the low-pressure oil inlet chamber, plunger boost chamber, metering valve, and outlet connection of the oil pump, resistant to diesel swelling and high temperature, not prone to hardening and leakage under long-term vibration and high-pressure working conditions, blocking the internal backflow of high-pressure fuel and pressure relief.
Double-layer thickened main shaft oil seal, completely solving the problem of main shaft leakage
Two pieces of brown oil-resistant skeleton oil seals, suitable for the assembly position of the oil pump drive main shaft, double-sealing to prevent fuel leakage caused by the reciprocating motion of the main shaft, avoiding diesel from flowing into the oil pan and diluting the engine lubricating oil.
Composite copper sealing gasket, high-pressure sealing of oil passage joints
Multiple-sized copper and composite metal gaskets, matching the high-pressure outlet threaded joint, pump body installation base, filling the threaded gap after assembly, no oil leakage and pressure relief under high-pressure working conditions, the gasket is neither too soft nor too hard, and is not prone to being compressed and deformed.
Complementary original factory specifications high-pressure oil passage joints + positioning bolts
Two sets of standard high-pressure oil passage threaded joints, complete set of stainless steel fastening bolts, uniform thread accuracy, replacing rusted and slipped old parts to ensure stable oil passage distribution, preventing fuel supply imbalance and uneven power distribution among cylinders.
Miniature filter cartridge assembly, intercepting impurities to protect the precision components of the plunger
Combined with yellow gasket + transparent plastic filter cartridge, assembled in the low-pressure oil inlet channel, filtering fine impurities in the diesel, reducing wear of the plunger and metering valve core, and reducing the frequency of major overhauls.
Complete set of rubber protective plugs, protecting the precision holes during disassembly and maintenance
Multiple-sized black rubber sealing plugs, equipped to seal various oil ports of the oil pump during maintenance and disassembly, preventing dust and impurities from entering the chamber and scratching the plunger and metering valve, with lower assembly rework rate.
