FAQ

Q1: Is this injector a direct fit for my Cat 320D excavator?
A: Yes, part numbers 254-4330 and 2544330 are the standard OEM injectors for the Cat C9 engine found in the 320D. However, we recommend checking your injector’s physical dimensions and connector type to confirm it matches your specific serial number prefix.

Q2: What is the difference between a remanufactured injector and a new one?
A: A remanufactured injector uses a genuine core that is disassembled, cleaned, and inspected. All worn components (like nozzles, plungers, and seals) are replaced with new parts meeting OEM standards. This offers the same performance and reliability as a new injector but at a significantly lower cost.

Q3: What maintenance is required after installing this injector?
A: After installation, it is critical to prime the fuel system to remove air. We recommend using a calibrated scan tool to perform a “cylinder cutout test” or “injector coding” (if required by your ECM) to ensure balanced fuel delivery. Always use clean, high-quality diesel fuel and replace fuel filters regularly to protect the injector from contamination.
