FAQ

Q1: How do I confirm this rotor fits my specific VE pump?
A: Please check the model number on your pump’s data plate. This rotor is specified for the “4/11 R” configuration. You should also verify the physical dimensions (standard size) against your old part. If you have the pump model number (e.g., Bosch VE4/11F), our customer service can assist in cross-referencing it with part numbers 146403-4920 or 9 461 615 358.

Q2: What are the common symptoms of a worn pump head rotor?
A: A failing rotor typically causes hard starting, unstable idling, reduced engine power, and excessive black smoke due to incorrect fuel timing or pressure. If you notice these issues alongside fuel leaks from the pump head area, the rotor is likely the culprit and requires immediate replacement to prevent damage to the pump housing.

Q3: Is professional installation required for this part?
A: Yes, replacing the pump head rotor is a precision task that requires disassembling the injection pump. We strongly recommend installation by a qualified diesel injection technician. The pump must be re-timed and calibrated on a test bench after the rotor is replaced to ensure proper engine performance and to avoid internal damage.
