FAQ

Q: What is the difference between a 4/10R rotor head and a standard one?
A: The “4/10R” designation refers to the internal configuration of the rotor, specifically the number of plungers and the direction of rotation. This particular model is designed for specific injection pump applications. Always verify your pump’s model and your old part’s markings to ensure a correct match.

Q: Is this part a direct replacement for my original 146401-2020 part?
A: Yes, this Head Rotor is manufactured to be a direct, drop-in replacement for the OEM part number 146401-2020 and its cross-reference 9461613951. No modifications are required for installation.

Q: What is the recommended maintenance for a new rotor head?
A: During installation, ensure the injection pump housing and all fuel lines are scrupulously clean to prevent contamination. It is also highly recommended to replace the pump’s seals and O-rings at the same time. After installation, the pump must be properly timed on the engine by a qualified diesel technician to ensure optimal performance and prevent engine damage.
