FAQ

Q1: How do I confirm this rotor head will fit my fuel injection pump?
A: First, identify the model number of your DPA pump. This rotor head (7180-616S) is a common replacement. The most critical physical measurement is the rotor head diameter, which is 8.5mm. Please measure your original head rotor or check your pump’s service manual to confirm the 8.5mm diameter and the “3/8.5R” specification match your requirements.

Q2: What is the installation procedure for this rotor head?
A: Installation is a complex task that requires mechanical expertise. It involves disassembling the hydraulic head of the DPA pump, removing the old rotor head, and installing the new one with precise torque settings. We highly recommend that installation be performed by a qualified diesel fuel injection technician to prevent damage to the pump and ensure correct timing and fuel delivery.

Q3: What are the signs that my rotor head needs replacement?
A: Common symptoms of a worn or failing rotor head include hard starting, engine misfiring, a loss of power, excessive black smoke, and poor fuel economy. If you notice these issues and have ruled out other fuel system problems (like clogged filters or injectors), the rotor head inside the injection pump is a likely culprit that requires professional inspection.
