1154168441 Original Excavator Fuel Injection Pipe for 6WG1

Part number 1154168441 is the original fuel injection pipe provided by ISUZU (Isuzu) for the 6WG1 series large displacement diesel engine. This pipe is the core pipeline of the ultra-high pressure common rail fuel system, dedicated to connecting the common rail pipe with the fuel injector, and delivering extremely high-pressure fuel exceeding 300MPa. Its universal model is clearly adapted to Hitachi's ultra large mining equipment equipped with a 6WG1 engine, mainly including EX3600-5/6, EX2600-5, ZX850-5, ZX870-5G and other ultra large hydraulic excavators of 80 tons or more. As a key component designated by the original factory and laser engraved with part numbers, its length, bending curvature, and specifications of the two end joints are precisely matched with the layout of the engine compartment and the pressure characteristics of the common rail system. It is strictly prohibited to use any non original substitutes, as any mismatch may result in pressure leakage, system damage, or serious safety risks.

Safety operation specifications: 1 Pressure relief: Before replacement, the pressure relief program must be triggered through a diagnostic instrument or the equipment must be left idle for at least 24 hours. It is absolutely forbidden to operate under pressure. 2. Cleaning: Use a lint free cloth and specialized cleaning agent to wipe the sealing cone and ball head of both ends of the joint, ensuring that there are no small particles. 3. Alignment installation: First, manually screw the flanged end into the first thread to ensure that the thread is aligned without any jamming. 4. Torque tightening: A calibrated torque wrench must be used to alternately tighten both ends in two steps according to the torque specified in the maintenance manual (usually 28-35 N · m). It is strictly prohibited to tighten based on feeling. 5. Leak detection: After installation, start the engine and run it at idle speed. Use a leak detection agent or white cloth to check each joint.
