8976023011 Original 4HK1 Engine Parts Injector Sleeve

Part number 8976023011 (also written as 8-97602301-1) is the original fuel injector sleeve (commonly known as fuel injector copper sleeve) that Isuzu uses for the 4HK1 and 6HK1 series diesel engines. This part is a key sealing and positioning component of the engine injector assembly. Its universal model is this part number, mainly suitable for construction machinery equipment equipped with Isuzu 4HK1 or 6HK1 engines, such as Hitachi ZX330 excavators. As an original precision component, its inner diameter, outer diameter, length, and material are precisely matched with the mounting holes of the engine cylinder head

This product is a cylindrical sleeve made of copper alloy material. Its core function is to press the fuel injector installation hole into the engine cylinder head for precise positioning of the fuel injector, and utilize the good thermal conductivity and plastic deformation ability of copper material to achieve high temperature and high pressure sealing between the fuel injector and the cylinder head after compression, preventing combustion gas from entering and oil leakage. As an original component, its dimensional accuracy, surface smoothness, and material composition all meet Isuzu's strict standards, ensuring long-term reliable operation.

Inspection and replacement: Whenever disassembling the fuel injector for major repairs or troubleshooting, it is necessary to check the inner wall of this sleeve for any scratches, wear, or deformation. This sleeve is a disposable component, and it is usually recommended to replace it with a new one after disassembly to ensure sealing performance. Attention: During installation, a small amount of engine oil can be applied to the outer wall of the sleeve to facilitate pressing in; Moisture proof and anti-collision measures should be taken during storage. This sleeve is a key component to ensure the normal operation of the fuel injector and prevent serious engine failures. When replacing it, it is necessary to use this original genuine sleeve (8976023011).
