FAQ

Q1: How do I know this Head Rotor will fit my John Deere injection pump?
A: Please check the OEM number (7123-345U or 7180-559U) stamped on your old rotor head. This part is a direct replacement for those specific numbers. If your pump uses a rotor marked “349U” with a 6/9R configuration, it is also compatible. We recommend matching the physical dimensions (12x10x10 cm) with your existing part.

Q2: What is the installation procedure for this part?
A: Installation requires specialized knowledge of diesel fuel injection systems. We strongly recommend having a qualified diesel mechanic perform the replacement. The head rotor is a precision component; improper installation can lead to pump failure or engine damage. Ensure the pump is clean and free of debris during assembly.

Q3: How long does this part typically last under normal working conditions?
A: With proper installation and using clean, filtered fuel, this head rotor can provide a service life comparable to OEM parts, often exceeding 2,000-3,000 hours of operation. Regular maintenance of the fuel system (e.g., replacing filters and draining water separators) will significantly extend its lifespan.
