FAQ

Q1: Is this injector a direct fit for my Caterpillar 320D excavator with a C7 engine?
A: Yes, the 10R-7225 / 387-9427 injector is a standard replacement for the C7 engine found in many 320D and 323D excavators. However, we recommend checking the injector part number printed on your current unit to confirm a match before purchase.

Q2: What is the recommended installation procedure for this remanufactured injector?
A: Professional installation is strongly recommended. Key steps include: 1) Thoroughly cleaning the injector bore in the cylinder head. 2) Replacing the copper washer and O-rings with the new ones provided. 3) Tightening the hold-down clamp to the manufacturer’s specified torque. 4) After installation, the injector coding must be programmed into the engine ECU using a diagnostic tool for optimal performance.

Q3: How should I store a spare injector before installation?
A: Store the injector in its original packaging in a clean, dry environment. Keep the protective caps on the fuel inlet, outlet, and nozzle tip to prevent contamination. Avoid exposure to extreme temperatures or moisture.
