FAQ

Q1: Is the 146400-2220 rotor a direct replacement for my Mitsubishi 4D55 VE pump?
Yes, this rotor is designed as a direct OE replacement for the VE-type injection pump used in the Mitsubishi 4D55 engine. It matches the original specifications for fitment and function. However, we recommend verifying your pump’s model number to ensure compatibility.

Q2: What maintenance is required for the VE pump head rotor after installation?
After installation, ensure the fuel system is free of contaminants by using high-quality diesel filters. Regularly check for fuel leaks and monitor engine performance. The rotor itself is a wear item and should be inspected during pump overhauls, typically every 100,000-150,000 km depending on operating conditions.

Q3: Can this rotor be used in Isuzu engines as well?
Yes, this rotor is compatible with many Isuzu diesel engines that utilize the VE-type injection pump, particularly 4-cylinder models. However, we advise cross-referencing your OEM part number (e.g., 146400-2220) with your Isuzu engine specifications to confirm fitment before purchase.
