FAQ

Q1: Is this rotor head a direct replacement for my VE pump?
A: Yes, this part is designed as a direct OE replacement. It matches the dimensions and specifications of the original 146403-4920 and 9 461 615 358 parts. However, we always recommend verifying your pump’s model number and existing rotor diameter (11mm) to ensure 100% compatibility.

Q2: What are the signs that my injection pump rotor head needs replacement?
A: Common symptoms include engine misfiring, hard starting, loss of power, black smoke from the exhaust, and fuel leaks around the pump. A worn rotor head can cause internal leakage, leading to poor fuel pressure and timing. If you experience these issues, particularly on a VE pump, this component is a likely culprit.

Q3: Do you provide installation instructions or technical support?
A: This part is intended for use by qualified diesel technicians familiar with injection pump repair. While we do not provide step-by-step installation guides, we can offer technical data sheets and dimensional drawings upon request. For complex rebuilds, professional service is strongly recommended to ensure proper calibration and timing.
