FAQ

Q1: How do I confirm this 7185-626L rotor head fits my fuel injection pump?
A: Please check the model number stamped on your existing rotor head or your fuel injection pump’s nameplate. This part is specifically designed for DPT-type pumps using the 4/7R configuration. If you are unsure, please provide us with your pump’s serial number or a photo of the old part for verification.

Q2: What is the installation difficulty level for this part?
A: Replacing a rotor head is a precision task that requires specialized tools (e.g., a rotor puller) and knowledge of fuel injection pump calibration. We strongly recommend that installation and timing adjustment be performed by a qualified diesel fuel injection technician to ensure proper function and safety.

Q3: What maintenance is recommended for the new rotor head?
A: Ensure the fuel system is clean and free of contaminants before installation. Use only high-quality, clean diesel fuel and replace the fuel filter regularly. During installation, lubricate the rotor head with clean diesel fuel or assembly oil. No additional maintenance is required for the rotor head itself, but regular system checks are advised.
