FAQ

Q1: How do I confirm this injector fits my Caterpillar C7 engine?
A: Please check the injector part number stamped on your current unit. It should match one of our cross-references: 387-9430, 10R-4761, or 10R4761. For excavator applications like the E320d, this is a standard fit. If you are unsure, contact us with your engine serial number (ESN) and we will verify compatibility for you.

Q2: What are the common signs of a failing HEUI injector on a C7 engine?
A: Common symptoms include hard starting, rough idling, white or black smoke from the exhaust, a noticeable loss of power under load, and increased fuel consumption. If you experience these issues, it is recommended to replace the injector promptly to avoid damage to other engine components like the cylinder head or piston.

Q3: Do I need to replace the injector sleeve or O-rings when installing a new injector?
A: Yes, it is highly recommended. When replacing a C7 HEUI injector, you should always install a new copper washer (injector seal) and new O-rings. Reusing old seals can lead to combustion gas leakage into the fuel system or coolant system, causing performance issues and potential engine damage. We recommend purchasing a seal kit separately for a complete and reliable repair.
