FAQ

Q: How do I know if the HX.4 or HX.5 head rotor is the correct part for my pump?
A: You must first identify the model of your fuel injection pump. The HX.4 and HX.5 are specific head rotor designs. Please check the existing part number on your current head rotor or consult your pump’s service manual. This part is designed for use in pumps fitted to the Yanmar engine models listed in the compatibility section.

Q: Is this a complete pump or just the head rotor assembly?
A: This is the Fuel Pump Head Rotor only. It is the central rotating and distributing component inside the fuel injection pump. It is not the entire pump assembly. Installation should be performed by a qualified diesel technician to ensure proper calibration and timing.

Q: What is the recommended maintenance after installing this remanufactured head rotor?
A: After installation, it is critical to prime the fuel system to remove any air. The injection pump timing should be checked and adjusted according to the engine manufacturer’s specifications. We also recommend replacing the fuel filter and using clean, high-quality diesel fuel to maximize the life of the new component.
