FAQ

Q1: Is this injector a direct fit for my Komatsu PC78 excavator with a 4D95 engine?
A: Yes, the OEM number 3800875 is the standard injector for the Komatsu 4D95 engine found in the PC78 series. However, please check the engine serial number (e.g., 4D95-xxxxx) to ensure it matches the specific sub-model of your engine.

Q2: What is the installation procedure for this injector?
A: Installation requires basic mechanical skills. Remove the old injector, clean the mounting hole, replace the copper washer, and torque the new injector to the manufacturer’s specification (typically around 50-60 Nm). We recommend replacing the fuel return lines and seals at the same time for optimal performance.

Q3: How do I know if my injector is failing and needs replacement?
A: Common symptoms of a failing injector include rough idling, excessive black smoke from the exhaust, a drop in engine power, poor fuel economy, and hard starting. If you experience any of these issues, testing the injectors is recommended.
