FAQ

Q: Is this head rotor a direct replacement for the 326-4635 part on my 320D?
A: Yes, this part is specifically remanufactured to replace the OEM 326-4635 pump head rotor for the Cat 320D with a C6.4 engine. It is a direct fitment component for the fuel injection pump.

Q: What is the difference between a new and a remanufactured head rotor?
A: A remanufactured unit is a previously used part that has been completely disassembled, cleaned, inspected, and rebuilt to OEM specifications. Worn components like the high-speed steel rotor are replaced. This provides a high-quality, reliable part at a significantly lower cost than a new OEM unit, with the same performance standards.

Q: What maintenance is recommended after installing this part?
A: After installation, it is crucial to prime the fuel system to remove any air. Check for fuel leaks at the pump connections. We also recommend replacing the fuel filter and ensuring the fuel is clean to maximize the lifespan of the new head rotor and the entire injection system.
