FAQ

Q: How do I know if this 7180-819U head rotor is the correct part for my pump?
A: The 7180-819U is a specific part number for the head rotor in a DPA pump. You should visually verify the part number stamped on your old head rotor. Additionally, ensure your pump uses the 4/9R plate configuration. If your old rotor is stamped with a different number (e.g., 7180-820U), this assembly may not be a direct match.

Q: What are the common symptoms of a failing head rotor in a DPA pump?
A: Common symptoms include difficulty starting the engine, especially when hot, erratic idling or surging, a lack of power under load, and black smoke from the exhaust. These issues are often caused by wear on the internal surfaces of the head rotor and the matching drive rotor.

Q: Are there any special tools required for installing this head rotor assembly?
A: Yes, rebuilding a DPA pump requires specialized tools and a clean, dust-free environment. The pump must be correctly timed and shimmed during reassembly. This task is best performed by a qualified diesel injection service technician. Incorrect installation can lead to pump failure or engine damage.
