FAQ

Q1: Is this injector a direct “plug-and-play” replacement for my harvester’s engine?
A1: Yes, this remanufactured injector is designed as a direct OEM replacement for part numbers 1816187C3 and AFA63800AA. It matches the original physical dimensions, electrical connectors, and performance specifications. However, we always recommend verifying the part number stamped on your old injector and consulting your engine service manual for final confirmation before installation.

Q2: What is the difference between “remanufactured” and “new” in terms of performance and reliability?
A2: Our remanufactured injectors are restored to original OEM performance standards. The core is completely disassembled, cleaned, fitted with new critical internal components, and rigorously tested. They offer performance and reliability equivalent to new units at a significantly lower cost, making them an excellent, cost-effective solution for professional repairs without compromising on quality.

Q3: Do you provide support for international customers regarding import duties and customs?
A3: Yes, as experienced B2B exporters, we provide all necessary shipping documents (commercial invoice, packing list) required for customs clearance in your country. While import duties and taxes are the responsibility of the buyer and vary by destination, our accurate documentation helps streamline the process. We can also recommend freight forwarders upon request.
