FAQ

Q1: How do I confirm this head rotor (7123-340U) fits my injection pump?
A: First, identify your engine model (e.g., 4248) and your injection pump’s model number. Visually inspect your current head rotor for the part number (7123-340U, 7180-550U, or 7180-668U) and the “4/9R” designation. If these numbers match your existing part, this rotor is a direct fit.

Q2: What is the typical installation procedure for a head rotor?
A: Installation requires mechanical expertise. The process involves disassembling the injection pump, removing the old head rotor and drive shaft, cleaning all components meticulously, installing the new head rotor with proper torque specifications, and recalibrating the pump on a test bench. We strongly recommend installation by a qualified diesel fuel injection technician.

Q3: What is the recommended maintenance or inspection interval for this part?
A: The head rotor is a high-wear component. It is typically replaced during a full injection pump overhaul, which is generally recommended every 200,000 to 300,000 kilometers or 6,000 to 8,000 hours of operation, depending on fuel quality and operating conditions. Regular inspection of the pump for fuel leaks or performance issues can indicate the need for earlier replacement.
