FAQ

Q: How do I know if this head rotor fits my Perkins engine?
A: This part is designed for DPA-type fuel injection pumps used on Perkins 4-cylinder engines. The most reliable way to confirm fitment is to check the part number on your existing pump head rotor. If it matches 7123-340W or 7180-550W, this is the correct replacement part.

Q: What is the typical installation process for a head rotor?
A: Replacing a head rotor is a specialized task that requires disassembling the fuel injection pump. It is highly recommended that this work be performed by a qualified diesel injection technician. The process involves removing the pump, disassembling the hydraulic head, replacing the rotor, and recalibrating the pump on a test bench.

Q: What maintenance is required after installing a new head rotor?
A: After installation, ensure the fuel system is clean and free of contaminants. It is crucial to use clean, high-quality diesel fuel and replace the fuel filter. We recommend having the complete fuel injection pump calibrated and timed by a professional to ensure optimal engine performance and fuel efficiency.
