FAQ

1. How do I confirm this 9mm rotor head will fit my injection pump?

First, verify that your pump is a DPA (Distributor Pump A) type. Second, check the existing part number on your old rotor head. This part is a direct replacement for 7180-722U, 248U, 246, and 724B. Finally, measure the diameter of your old rotor head; it must be exactly 9mm for this part to fit correctly.

2. What are the common signs of a failing injection pump rotor head?

Common symptoms include hard starting, engine misfiring, a rough idle, black smoke from the exhaust due to incomplete combustion, and a noticeable decrease in engine power and fuel economy. A worn rotor head can cause uneven fuel delivery to the injectors.

3. Is professional installation recommended for this part?

Yes, absolutely. Replacing a rotor head involves disassembling the injection pump, which requires specialized tools and knowledge to ensure proper timing and calibration. We strongly recommend that this repair be performed by a qualified diesel injection technician to avoid damage to the pump or engine.
