1154158471 Excavator ISUZU 6BG1 Engine INJECTION PIPE for ZX200 

Part number 1154158471 is an original high-pressure fuel injection pipe (high-pressure fuel pipe) specifically designed for Isuzu 6BG1 series diesel engines. This component is mainly suitable for multiple Hitachi medium-sized hydraulic excavators equipped with this engine, including ZX200, ZX200-3G, ZX210, ZX230, ZX240-3G, ZX250-3G, ZX270, as well as EX200-3C, EX200-5, EX200-6 and other models. Its universal part number may follow the numbering rules of 1-15415847-0 or 1154158470.
 

This product is an Isuzu original high-pressure fuel injection pipe, which is the core component of the engine common rail fuel system that bears the highest pressure and delivers fuel to each cylinder injector. Its core function is to ensure precise fuel delivery without leakage or pressure loss at injection pressures of up to 1800-2000 bar, directly affecting the engine's power, economy, and emission levels. Oil pipes are usually made of multi-layer co extruded high-strength alloy steel pipes, with smooth inner walls to reduce flow resistance, and external anti-corrosion coatings and braided sheaths to withstand the continuous vibration, high temperature, and chemical corrosion of the engine compartment.
 

Before starting each shift, visually inspect all high-pressure oil pipes for oil stains, abnormal bulges, cracks, or wear (especially paying attention to the contact and friction with adjacent components); Check each fixed clamp for looseness every 500 working hours. Strictly replace the fuel filter according to the maintenance cycle to prevent impurities from scratching the inner wall of the fuel pipe or blocking the fuel injector. Fault Symptoms and Replacement Timing: Once any form of oil pipe leakage, visible damage to the pipe body, or uneven fuel supply symptoms such as cylinder shortage, power reduction, black smoke emission, etc. are found in the engine, it must be stopped immediately for replacement.
