FAQ
Q: How do I confirm this rotor head fits my injection pump?
A: Please check the part number on your existing rotor head. It must match one of the numbers listed in the “OEM Cross-Reference” section (146401-3020 or 1464013020). Also, verify your pump model (e.g., Isuzu inline pump). If you are unsure, please contact us with your pump’s model and serial number for verification.
Q: What is the installation procedure for this part?
A: Installation of a rotor head is a precision task that should be performed by a qualified diesel fuel injection technician. It requires specific tools to remove the head lock nut and to correctly time the rotor. Incorrect installation can lead to pump failure or engine damage. We recommend consulting the service manual for your specific pump model.
Q: Does this part require any additional components for a complete repair?
A: Yes, it is highly recommended to replace the rotor head as part of a complete pump overhaul kit. You should also replace the delivery valves, plunger, spring, and all seals and gaskets to ensure optimal performance and longevity of the rebuilt pump. Using only the rotor head may lead to premature failure of other worn components.
