FAQ

Q1: How do I verify if this rotor head fits my injection pump?

Confirm your existing part number matches 146403-3120 or 9461615073. This part is designed for 4L and 10L diesel injection pumps. If you are unsure, contact us with your pump model and serial number for verification.

Q2: What is the recommended installation procedure?

Installation should be performed by a qualified diesel mechanic. Ensure the pump housing is clean and free of debris. Lubricate the rotor head with clean diesel fuel before installation. Torque to manufacturer specifications to avoid damage. Always replace seals and gaskets during installation.

Q3: How should I maintain this rotor head for optimal performance?

Use clean, high-quality diesel fuel and replace fuel filters regularly. Contaminants are the primary cause of rotor head wear. If the engine shows signs of poor fuel delivery (hard starting, misfiring), inspect the rotor head for scoring or wear. We recommend replacement every 2,000-3,000 operating hours depending on fuel quality and operating conditions.
