FAQ

Q1: What does “Remanufactured” mean for this head rotor?
A: A remanufactured head rotor is a used core that has been completely disassembled, cleaned, inspected, and rebuilt to meet OEM specifications. Worn components are replaced with new parts, and the unit is tested to ensure it performs identically to a new unit, offering a cost-effective and reliable alternative.

Q2: How do I know if this head rotor is the correct fit for my pump?
A: Please compare the part number stamped on your existing head rotor with the OEM numbers listed (146403-4820, 146403-4920, 146403-6120, 146403-6620, 146403-6820). If your number matches one of these, this part is a direct replacement. If you are unsure, please contact us with your engine model and pump serial number for assistance.

Q3: What is the recommended maintenance for this fuel injection pump component?
A: For optimal performance and longevity, ensure the fuel system is clean and free of contaminants. Use high-quality diesel fuel and replace your fuel filters according to the engine manufacturer’s schedule. When installing, ensure the rotor is properly lubricated with clean engine oil or fuel. Professional installation by a qualified diesel technician is highly recommended.
