FAQ

Q: Is this rotor head a direct fit for my DPA pump marked with part number 7139235G?
A: Yes, this is a direct OEM replacement for part number 7139235G (also listed as 7139-235G). It is designed for the 3/8R pump head configuration. Always compare the physical part and numbers before installation.

Q: What is the primary advantage of the high-speed steel material used in this part?
A: High-speed steel offers superior hardness, heat resistance, and wear characteristics compared to standard steels. This is critical for the rotor head, which operates at high rotational speeds under extreme pressure, ensuring a longer service life and maintaining precise fuel metering over time.

Q: Do you provide technical support for installation and troubleshooting?
A: While we supply the component, installation should be performed by a qualified diesel technician familiar with DPA fuel injection pumps. We can provide general documentation. For complex troubleshooting, we recommend consulting the engine or pump manufacturer’s service manual.
