FAQ

Q1: Is this injector a direct “plug-and-play” replacement for my Caterpillar C4.4 engine?
A1: Yes, this remanufactured injector is designed as a direct replacement for OEM numbers 295050-0421 and 370-7287. It should fit and function identically to the original part once installed and calibrated using the appropriate diagnostic equipment.

Q2: What is included in the “remanufactured” process, and how does it differ from “new”?
A2: Our remanufacturing process involves completely disassembling a used OEM core, replacing all seals and high-wear internal components with new, high-quality parts, machining critical surfaces, and performing dynamic calibration tests. The result is a unit that performs to original specifications at a lower cost than a brand-new OEM injector, offering excellent value and reliability.

Q3: Do I need to replace all injectors at once, or can I replace just one?
A3> While it is possible to replace a single failing injector, for optimal engine balance, performance, and long-term reliability, it is often recommended to replace injectors in sets, especially if the engine has high hours or the other injectors are of similar age. Consult your engine service manual or a qualified diesel technician for the best recommendation for your specific situation.
