FAQ

1. How do I verify that the 7189-871L rotor head fits my injection pump?

Please check the existing part number on your current rotor head. It must match 7189-871L and the rotor number 004L. Also, confirm the physical specification is 4/7R. If you are unsure, consult your pump’s service manual or contact us with your pump model and serial number for assistance.

2. What is the recommended installation procedure for this rotor head?

Installation should be performed by a qualified diesel technician in a clean environment. Ensure the pump housing is free of debris. Lubricate the rotor with clean diesel fuel or assembly oil before installation. Follow the manufacturer’s torque specifications and timing procedures. Improper installation can lead to pump failure or engine damage.

3. How can I extend the service life of the DPT head rotor?

Use high-quality, clean diesel fuel and replace fuel filters at recommended intervals. Avoid running the fuel tank low to prevent air ingress and contamination. Regular maintenance of the fuel injection system, including checking for water and debris, will significantly prolong the life of the rotor head and other pump components.
