FAQ

Q1: What does the “4/10R” specification mean for this rotor head?
A1: The “4/10R” designation refers to the specific design and configuration of the rotor head, indicating the number of plungers (4) and the pump rotation direction (R for Right/Clockwise). This specification is critical for matching the rotor head to the correct fuel injection pump model to ensure proper fuel distribution and timing.

Q2: How do I know if this 146404-1620 rotor head is the correct part for my pump?
A2: To confirm compatibility, you must first check the model number on your fuel injection pump’s nameplate. The part number 146404-1620 is a specific OEM number. If your pump requires this exact part, it will be a direct fit. We strongly recommend comparing your old rotor head’s physical dimensions and the number of plungers (4) against our product image and specifications before purchase.

Q3: What is the recommended installation procedure for this component?
A3: Installation of a rotor head is a complex task that should be performed by a qualified diesel fuel injection technician. It requires a clean, dust-free environment and specialized tools. The process involves disassembling the pump head, carefully replacing the rotor head, and then re-calibrating the pump on a test bench to ensure correct fuel delivery and timing. Improper installation can lead to engine damage or poor performance.
