FAQ

Q1: Is this fuel injector a direct replacement for the original Komatsu 6156-11-3300 part?

Yes, this injector is designed as a direct, drop-in replacement for the Komatsu OEM part number 6156-11-3300. It matches all physical dimensions, connection types, and performance specifications, requiring no modifications for installation on the 6D125 engine.

Q2: What are the common symptoms of a failing injector on a PC400-7 excavator?

Common symptoms include rough idling, excessive black smoke from the exhaust, a noticeable decrease in engine power or fuel efficiency, hard starting, and engine misfiring. Replacing faulty injectors promptly can prevent further damage to the engine’s cylinder heads and pistons.

Q3: Are there any special installation procedures or torque specifications I should be aware of?

We recommend replacing injector copper gaskets and O-rings during installation to ensure a proper seal. It is critical to tighten the injector retaining clamp to the manufacturer’s specified torque (typically around 69 Nm for this model, but always verify with your service manual). After installation, the engine should be bled of air in the fuel system before starting.
