We back our quality with a 4-month warranty against manufacturing defects, ensuring your complete satisfaction.

FAQ

Q1: Is this injector a direct fit for my Caterpillar C4.4 engine?

A: Yes, this injector (part number 370-7280 / 295050-0331) is a direct OEM replacement for the Caterpillar C4.4 diesel engine. It is a plug-and-play component, but we always recommend comparing your old injector’s part number and physical dimensions to ensure perfect compatibility.

Q2: What is included in the remanufacturing process?

A: Our remanufacturing process involves complete disassembly, thorough cleaning, and replacement of all critical wear components including the nozzle needle, control valve, and all sealing elements (O-rings and copper washers). The injector is then reassembled and 100% tested to meet strict OEM performance standards for flow rate and pressure.

Q3: What should I do after installing the new injector for optimal performance?

A: After installation, it is critical to perform a fuel system priming procedure to remove any air from the fuel lines. We also highly recommend having the injector codes programmed to the engine’s ECU using a diagnostic tool. This ensures the engine management system delivers the correct fuel quantity for each cylinder, maximizing performance and fuel economy. Always use new, high-quality fuel filters during the service.
