FAQ

Q: What does the specification “3/9.5R” mean for this head rotor?
A: The “3/9.5R” specification typically refers to the plunger diameter and cam ring rotation. “3” often indicates a 3-cylinder pump application, “9.5” is the plunger diameter in millimeters, and “R” indicates the direction of rotation (Right). It is crucial to match this specification with your original pump for correct fuel delivery and timing.

Q: My pump has the number 7180-611W. Is this part a direct replacement?
A: Yes, this head rotor assembly is a direct replacement for both OE numbers 7139-709W and 7180-611W. These numbers are cross-referenced as interchangeable parts for the same DPA pump model. Please ensure your pump uses the “3/9.5R” rotor specification.

Q: What is the expected lifespan of this head rotor, and any installation tips?
A: The lifespan depends on fuel quality and operating conditions. High-quality fuel and clean injection systems will maximize its life. During installation, it is critical to ensure absolute cleanliness to prevent dirt ingress. The head and rotor are a matched set and must be installed together. Lubricate with clean diesel fuel during assembly and ensure the drive slot aligns correctly with the pump drive shaft. We recommend installation by a qualified diesel technician.
