FAQ

1. What is the difference between the 7180-819U head rotor and the 820U rotor?
The 7180-819U is the complete head and rotor assembly. The “820U” refers specifically to the rotor component itself. This listing includes the complete assembly (Head Rotor 7180-819U) which contains the 820U rotor (4/9R configuration) as a matched set. This ensures proper fuel metering and timing.

2. How do I know if this head rotor is compatible with my DPA pump?
The “4/9R” in the rotor specification indicates the pump’s plunger configuration (4 plungers, 9mm diameter, right-hand rotation). You must verify that your existing DPA pump has this exact configuration. Always compare the part number on your old head rotor (7180-819U) and check the rotor stamp (820U 4/9R) before installation.

3. What maintenance is recommended after installing a new head rotor?
After installation, the fuel injection pump must be properly timed and calibrated on a test bench by a qualified diesel technician. It is also recommended to replace the fuel filter and ensure the fuel supply is clean and free of contaminants to protect the precision components of the new head rotor and extend its service life.
