Description
Product Overview
Under long-term high-temperature and high-pressure conditions, the original rubber sealing ring of the side sealing cover plate of the high-pressure oil pump becomes aged and hardened, and the fastening bolts become fatigued and loose. This will cause diesel leakage from the gap of the oil pump housing, continuous pressure loss inside, leading to difficulties in cold start, insufficient power, and the engine fault light to illuminate. This set of maintenance package integrates the sealing cover plate, all sealing rubber rings, and the complete set of matching fastening screws. During disassembly and repair, the entire set can be directly replaced, eliminating the cumbersome process of separately matching gaskets, bolts, and sealing rings, significantly reducing the repair time and suitable for maintenance of light trucks, construction machinery, agricultural machinery, and electric fuel injection high-pressure oil pumps.
Unique Features of the Exclusive Set of Accessories
An irregularly shaped galvanized metal sealing cover plate that perfectly fits the contour of the oil pump housing
An integrated stamping-formed irregularly shaped galvanized steel sealing cover, with standard threaded installation holes reserved at the four corners, the surface is flat without deformation, after locking, it completely covers the reserved oil passage of the oil pump, preventing the internal high-pressure fuel from leaking outward, the galvanized layer is rust-resistant and resistant to diesel corrosion, and it is not prone to rust and perforation over long-term use in the engine compartment.
Multiple specifications of irregular + circular oil-resistant O-rings, multi-layer sealing to lock the oil pressure
The kit is equipped with square irregular-shaped rubber rings, irregularly shaped rubber rings, and standard circular O-rings, respectively, to adapt to the contact surface of the cover plate, the top rod body, and the sealing points of the oil passage; using oil-resistant nitrile rubber material, it can withstand high engine temperatures and diesel immersion, and is not prone to shrinkage, cracking, and leakage under high-pressure conditions.
Complete set of extended stainless steel fastening bolts, evenly locking the seal without loosening
Complementary 3 extended full-thread stainless steel long bolts + 1 micro positioning screw, the bolts are rust-resistant and not prone to rusting and seizing, the extended rod body is suitable for the installation depth of the oil pump housing, four points are evenly pressed against the cover plate, the sealing rubber ring is under balanced force, preventing local oil leakage, and not prone to loosening in bumpy and heavy-duty conditions.
All accessories are standardized in size and compatible, no need for grinding to adapt
The sealing cover plate, sealing rubber ring, and fastening screws are all processed according to the corresponding specifications of the oil pump cavity, replacement is direct, there are no size deviations or assembly不到位 rework problems， making the repair simple.
Layered sealing structure design， double barrier to prevent fuel leakage and pressure loss
Two-layer sealing rubber rings combined with solid metal sealing cover plate form two internal and external sealing barriers， effectively blocking the leakage of high-pressure fuel from the gap of the housing， stabilizing the internal fuel supply pressure of the oil pump， and restoring the normal power output of the engine.
Application Scenarios
Suitable for light-duty diesel trucks with electric fuel injection common rail high-pressure oil pumps， small wheeled excavators， agricultural tractors， mobile diesel generators， suitable for short-distance urban transportation， field farming， light-load construction sites， and small-sized electric fuel injection common rail diesel power equipment with oil pump sealing maintenance.
