FAQ

Q: How do I confirm that this head rotor (7189-522K) is the correct part for my pump?
A: First, visually inspect your existing rotor for the number “528K” and the pump housing for the number “7189-522K”. This part is specifically designed for DPA pumps with a 4/7L specification. If your pump is a different model or specification, this part will not be compatible. We recommend consulting your pump’s service manual or a qualified diesel technician if you are unsure.

Q: What is the recommended installation procedure for this head rotor?
A: Installation of a DPA head rotor is a complex procedure requiring specialized tools and knowledge of fuel injection systems. It involves precise alignment and torquing. We strongly advise that this component be installed by a certified diesel injection service professional. Incorrect installation can lead to pump failure and engine damage.

Q: What maintenance is required for the fuel injection pump after replacing the head rotor?
A: After replacing the head rotor, the fuel injection pump must be properly timed and calibrated on a test bench before being reinstalled on the engine. It is also crucial to replace the fuel filter and ensure the fuel system is free of contaminants (water, dirt, air). Regularly changing the fuel filter and using clean, high-quality diesel fuel will maximize the life of the new rotor and the entire pump system.
