FAQ

Q1: How do I confirm this head rotor fits my injection pump?
A: Please compare the part number on your existing rotor head. The primary number is 7139-764T. If your pump uses a 10mm rotor for a 4-cylinder DPA pump (often referred to as 3/9L), this part is the correct replacement. If you are unsure, please contact us with your pump model or existing part number for verification.

Q2: What is the installation procedure for this DPA head rotor?
A: Installation requires disassembling the DPA pump head. It is a precision component that must be installed by a qualified diesel technician. Ensure the pump housing and mating surfaces are clean. Torque settings must be followed according to the pump manufacturer’s specifications to avoid damage or leakage.

Q3: How can I maximize the lifespan of this rotor head?
A: Longevity depends on fuel quality and system maintenance. Always use clean, high-quality diesel fuel and replace your fuel filters regularly. Contaminated fuel is the primary cause of premature wear in injection pump components. We also recommend checking the pump for internal wear and replacing seals during installation for optimal performance.
