FAQ

Q1: Is this pump head rotor a direct replacement for my CAV DPA pump?
A: Yes, this rotor (part numbers 7139-709W, 7180-611W, 708W) is designed as a direct replacement for CAV Lucas DPA pumps. However, please confirm your pump’s rotor specification (3/9.5R) and measure the rotor diameter to ensure compatibility. The 9.5mm diameter is critical for correct fitment.

Q2: What are the installation requirements for this part?
A: Installation should be performed by a qualified diesel technician. The rotor requires precise alignment and lubrication during assembly. We recommend replacing the rotor along with the pump head, rollers, and seals for optimal performance. Ensure the fuel system is clean to prevent contamination.

Q3: How can I maintain the pump head rotor for long service life?
A: Use clean, high-quality diesel fuel and replace fuel filters regularly. Contaminated fuel is the primary cause of rotor wear. If the engine shows signs of hard starting, smoke, or power loss, inspect the injection pump components. Our rotor is made from high-speed steel for enhanced wear resistance, but proper fuel maintenance is essential for longevity.
