FAQ

Q1: How do I confirm that the 7180-759W rotor head is compatible with my DPA pump?
A: Check the identification plate on your fuel injection pump for the model number and rotor specification. The 4/9.5R marking indicates the rotor’s diameter and cam ring profile. If your pump requires a 4/9.5R rotor, this part is a direct fit. For further verification, consult your pump’s service manual or contact our technical support with your pump’s serial number.

Q2: What are the common signs of a failing DPA rotor head that requires replacement?
A: Symptoms include hard starting, engine misfiring, reduced power output, excessive black smoke, and irregular idling. A worn or damaged rotor head can cause inconsistent fuel pressure and timing. If you observe these issues after checking fuel filters and lines, inspecting and replacing the rotor head is a recommended step.

Q3: What installation precautions should I take when replacing the rotor head?
A: Ensure the work area is clean to prevent contamination of the fuel system. Lubricate the new rotor head with clean diesel fuel or assembly oil before installation. Follow the manufacturer’s torque specifications for the retaining nut and ensure the drive shaft is correctly aligned. After installation, prime the fuel system and check for leaks before starting the engine. Professional installation is recommended for optimal performance and longevity.
