FAQ

Q1: How do I confirm if this 7185-044L rotor head fits my DPA pump?
A: Please check the model number stamped on your existing pump head or the pump data plate. The 7185-044L is specifically for 7MM diameter shafts and 4-cylinder applications. If your pump uses a different shaft diameter (e.g., 6MM or 8MM) or has a different part number, it may not be compatible. We recommend measuring the diameter of your old rotor head before ordering.

Q2: What is the installation procedure for this rotor head?
A: Installation should be performed by a qualified diesel fuel injection technician. The process typically involves removing the pump top cover, extracting the old rotor head, cleaning the bore, and carefully pressing in the new rotor with the correct orientation. Proper torque settings are critical to prevent damage. We recommend replacing the pump seals and gaskets simultaneously.

Q3: How can I maintain the longevity of this pump head rotor?
A: Ensure that the fuel system is clean and free of contaminants. Use high-quality diesel fuel and replace fuel filters regularly. Contaminated fuel can cause scoring on the rotor surface, leading to premature failure. Additionally, avoid running the pump dry, as this can cause immediate damage to the rotor and pump head.
