FAQ

Q1: How do I confirm this part is compatible with my specific diesel pump?
A1: The most reliable method is to match the part number stamped on your original rotor head. Cross-reference it with the OEM numbers listed in the “OEM Cross-Reference” section above (7123-340U, 340U, 344U, 7180-550U). If unsure, please provide the model of your engine or injection pump, and our technical team can assist.

Q2: What is the installation process for this rotor head?
A2: Installation requires specialized knowledge and tools for diesel fuel injection systems. It involves disassembling the injection pump, replacing the old rotor and head assembly with this new unit, and performing precise calibration of fuel timing and pressure. We recommend installation by a certified diesel technician to ensure optimal performance and avoid damage.

Q3: What are the signs that my diesel pump rotor head needs replacement?
A3: Common symptoms include hard starting, loss of engine power, uneven idling, excessive black or white smoke from the exhaust, and increased fuel consumption. A diagnostic check of fuel injection pressure and timing will typically confirm if the rotor head or related components are failing.
