FAQ

Q1: Is this head rotor compatible with all VE pumps?
A: No. This specific 146403-3120 rotor is designed for 4-cylinder VE pumps, typically found in the Nissan CD17 engine. It is not suitable for 6-cylinder or in-line pump configurations. Please check your pump’s stamping for the “4/10L” marking.

Q2: What are the signs of a failing head rotor?
A: Common symptoms include hard starting, engine misfiring, reduced power, and excessive black smoke. A worn rotor disrupts fuel distribution timing. If you are rebuilding a VE pump, replacing the head rotor and drive pin is standard practice.

Q3: Do you provide installation instructions?
A: This is a precision internal pump component. Installation requires specialized tools and knowledge of diesel injection systems. We recommend installation by a certified diesel technician to ensure proper timing and sealing.
