FAQ

Q: What is the difference between the 7183-121K and the 7180-121K part numbers?
A: The 7183-121K is the model number for this specific DPS series head rotor. The 7180-121K is the primary OEM reference number that this part is designed to replace or cross-reference. Both numbers are used to identify the correct component for your fuel injection pump.

Q: How do I ensure this head rotor fits my injection pump?
A: Verify that your pump requires a DPS series head rotor with a 3/7L specification. Check your existing part for the numbers “7183-121K” or “7180-121K” and the rotor number “527K”. If you are unsure, please provide your pump model and serial number to our support team for cross-verification.

Q: What maintenance is recommended after installing a new head rotor?
A: After installation, it is critical to prime the fuel system to remove any air. We recommend using clean, high-quality diesel fuel and replacing the fuel filter at the same time. After initial operation, check for any leaks and ensure the engine runs smoothly. Adhering to the manufacturer’s service intervals for your injection pump will maximize the life of this component.
