FAQ

Q: Is this injector a direct fit for my Caterpillar 320D with a C7 engine?
A: Yes, the 243-4502 / 10R-4761 injector is designed as a direct replacement for the Caterpillar C7 engine in 320D excavators. However, we always recommend verifying your engine serial number and the existing injector’s OEM number to ensure 100% compatibility before installation.

Q: What is the installation requirement for this remanufactured injector?
A: Installation should be performed by a qualified diesel mechanic. It is crucial to replace the injector copper washers and O-rings with new ones (sold separately). After installation, the injector codes must be programmed into the engine ECU using a diagnostic tool to ensure proper fuel delivery and engine balance.

Q: How do I maintain this injector for optimal performance?
A: Use high-quality diesel fuel and replace the fuel filters at recommended intervals. Regularly check for fuel leaks around the injector base. Contaminated fuel is the primary cause of injector failure, so ensure your fuel system is clean and free of water and debris.
