FAQ

1. How do I know if this rotor head fits my injection pump?

This rotor head is specifically designed for the Isuzu C240 engine using a 4/9L (4-cylinder, 9mm plunger) injection pump. You must verify your pump’s model number and plunger size. The OEM numbers 146401-1920 and 9461614180 must match the part currently installed.

2. What is the installation procedure for this part?

Installation should be performed by a qualified diesel technician. It involves disassembling the injection pump head, removing the old rotor head, and carefully installing the new one with proper torque specifications. The pump will require recalibration on a test bench after installation to ensure correct fuel timing and delivery.

3. How can I ensure the long life of this rotor head?

Longevity depends on fuel quality and system cleanliness. Always use clean, high-quality diesel fuel and replace your fuel filters regularly. Ensure the injection pump is free of contaminants before installation. Regular maintenance of the entire fuel system will maximize the service life of the rotor head.
