FAQ

Q1: How do I know if this head rotor fits my specific pump?
A: Please check the part number on your current head rotor or pump data plate. This part is compatible with DPA pumps using part numbers 7139-764S or 7180-616S. If your pump is a different model, please contact us with your pump’s serial number for verification.

Q2: What is the installation procedure for this part?
A: Installation should be performed by a qualified diesel technician. It involves disassembling the injection pump, removing the old rotor, and installing the new one. Proper torque specifications and timing are critical. We recommend consulting your pump’s service manual for detailed steps.

Q3: What maintenance is required after replacing the head rotor?
A: After installation, the injection pump should be re-calibrated on a test bench to ensure correct timing, fuel delivery, and pressure settings. We also advise checking and replacing the fuel filter and cleaning the fuel system to prevent contamination from damaging the new component.
