4330222 Original EX200-5 excavator hydraulic motor

Part number 5154115070 is an original fuel pipe assembly specifically designed for Isuzu engines. This component is mainly used for various construction machinery equipped with Isuzu engines, especially excavators. Some models of brands such as Hitachi, Komatsu, and Kobelco may use this component. Due to differences in the specific models (such as 4HK1, 6HK1, 6WG1, etc.) and fuel system layouts of Isuzu engines installed on excavators of different brands and models, in order to ensure 100% compatibility and avoid leakage or fuel supply failures caused by mismatched interfaces, lengths, or pressure levels, it is strongly recommended that you conduct final compatibility verification with authorized dealers through the engine model and body serial number of the equipment.

This product is an original Isuzu pure fuel pipe component, which is the key "blood vessel" of the engine fuel supply system. It is usually made of multi-layer composite oil resistant rubber or metal (such as stainless steel), with a special coating designed internally to reduce fuel friction and static electricity accumulation. The components include the inlet pipe, return pipe, necessary joints, clamps, and sealing rings, forming a complete low-pressure fuel delivery circuit. Its core function is to operate stably within a wide temperature range of -40 ℃ to 135 ℃, withstand the pressure of the fuel system (usually 3-5 bar), and have excellent resistance to diesel corrosion, ozone, and low fuel penetration characteristics to meet strict emission regulations. As an original component, its size, bending radius, and connection interface are precisely matched with the engine, fuel filter, fuel pump, and other components to ensure efficient and leak free fuel delivery.

Installation and replacement: The replacement of fuel pipe components must be carried out by professionals in a well ventilated environment away from sources of fire. The process includes: releasing fuel system pressure; Mark and dismantle the old pipeline; Clean all connection interfaces; Replace all sealing rings and clamps; Install new components according to the original vehicle direction and fixed points, ensuring that the pipelines are not twisted, excessively bent, or interfere with moving parts; Tighten all joints to standard torque. After installation, start the engine, check for leaks at all connections, and lightly press the accelerator to exhaust the air in the pipeline.
