FAQ

Q: How do I know if this pump head rotor (146406-0620) fits my injection pump?
A: This rotor head is designed for Bosch VE-type rotary injection pumps. Please verify the existing part number on your rotor (e.g., 146406-0620 or 9 461 614 654) and the diameter (11mm) to ensure a match. If your pump uses a different rotor size or design, this part will not be compatible.

Q: What is the typical installation procedure for this part?
A: Installation requires disassembling the injection pump head. This is a precision operation that should be performed by a qualified diesel technician using the correct tools. It involves removing the old rotor head, cleaning the mating surfaces, and installing the new unit with precise torque settings. An incorrect installation can lead to pump failure.

Q: What maintenance is required after installing a new pump head rotor?
A: After installation, the injection pump must be re-calibrated on a test bench to set the correct fuel delivery timing and pressure. It is also recommended to replace the fuel filter and ensure the fuel system is free of contaminants to protect the new rotor and extend the life of the pump.
