FAQ

Q1: What is the exact function of this head rotor (7123-340W / 7180-550W) in the fuel injection pump?

This head rotor is a critical rotating component within the DPA fuel injection pump. Its primary function is to distribute high-pressure fuel to the correct injector at the precise time for engine combustion. It works in conjunction with the pump’s cam ring and rollers to meter and pressurize fuel for each cylinder.

Q2: How can I confirm this part will fit my pump before purchasing?

You can confirm fitment by checking the model number stamped on your existing head rotor or on the pump’s data plate. The most reliable method is to compare your current part number directly with our offered numbers: 7123-340W or 7180-550W. If your numbers match, this part is a direct replacement.

Q3: What are the key signs of a failing head rotor that would indicate a need for replacement?

Common symptoms of a worn or failing head rotor include hard starting, engine misfiring, loss of power, irregular idling, excessive black smoke, and a general decrease in fuel economy. Internal wear can also lead to fuel dilution of the engine oil. If you experience these issues, inspecting and testing the head rotor is a recommended diagnostic step.
