FAQ

Q1: Is this rotor head a direct fit for my Mitsubishi 4D55 engine?
Yes, this part is a direct OE replacement. It matches the exact specifications (size, rotation, and port configuration) of the original 146400-2220 and 9 461 610 167 parts, requiring no modifications for installation on a standard VE pump.

Q2: What does “4/10 Right” rotation mean for installation?
“4/10 Right” refers to the rotational direction and timing configuration of the rotor head within the injection pump. It indicates a right-hand rotation pump. You must ensure your existing pump is also a right-hand rotation type. If you are unsure, please check your pump’s data plate or consult a technician before ordering.

Q3: What is the typical lifespan of this rotor head, and how should I maintain it?
With proper fuel filtration and clean diesel, this rotor head can last for thousands of operating hours. We recommend replacing it as part of a full pump overhaul. To maximize lifespan, always use high-quality fuel filters and ensure the fuel system is free of water and contaminants.
