FAQ

Q: How do I confirm this head rotor fits my injection pump?
A: Verify your pump’s model number and the existing part number (7123-345M or 7180-559M). This rotor is typically used in pumps for 6-cylinder engines. If unsure, please contact us with your pump’s serial number for cross-referencing.

Q: Is professional installation required?
A: Yes. Replacing a head rotor involves disassembling the injection pump and precise calibration. We strongly recommend installation by a qualified diesel injection technician to ensure proper timing and fuel delivery.

Q: What is the typical lifespan of this head rotor?
A: Lifespan depends on fuel quality, operating conditions, and maintenance. Under normal conditions, a quality replacement rotor can last for thousands of hours. Using clean, high-quality diesel fuel and regular filter changes will maximize its service life.
