FAQ

1. Is this injector a direct replacement for the original Bosch 0445120231 on my Komatsu PC200-8?

Yes, this injector is designed as a direct OEM replacement. It matches the original Bosch specifications for the Cummins QSB6.7 engine in the PC200-8. No modifications are required for installation, but we recommend checking the injector code on your existing unit to ensure compatibility.

2. What is the recommended installation procedure for this common rail injector?

Installation should be performed by a qualified diesel technician. Key steps include: ensuring the fuel system is clean and depressurized, replacing the copper sealing washer, tightening to the manufacturer’s specified torque (typically 25-30 Nm for injector clamp), and using a diagnostic tool to perform a cylinder cut-out test or flow calibration if required by the ECU.

3. How can I maintain this injector for optimal performance and longevity?

Use high-quality diesel fuel with proper lubrication properties. Replace the fuel filter regularly (every 250-500 hours of operation). Avoid running the engine with a clogged air filter or contaminated fuel. If you experience rough idling or poor power, have the injector tested on a calibrated test bench to check for wear or clogging.
