FAQ

Q1: How do I verify if this Head Rotor Metering Valve fits my DP200 pump?

Compare the part number stamped on your existing rotor with the list of OEM cross-references provided above. The most common numbers are 7123-930G and 7139559D. If your part number is listed, this unit is a direct replacement. For additional verification, measure the diameter (7MM) and ensure it matches your pump’s specifications.

Q2: What is the installation procedure for this metering valve?

Installation should be performed by a qualified diesel technician. The process involves disassembling the DP200 pump head, removing the old rotor, cleaning the mounting surface, and carefully inserting the new rotor. Ensure proper alignment and torque specifications are followed to prevent damage. Always refer to the pump manufacturer’s service manual for detailed instructions.

Q3: What maintenance is recommended to extend the life of this component?

Regularly inspect the fuel system for contaminants, as dirty fuel is the primary cause of premature rotor wear. Use high-quality fuel filters and replace them according to the engine manufacturer’s schedule. Additionally, ensure the injection pump is properly lubricated with clean engine oil. Following these steps will maximize the service life of the metering valve.
