FAQ

Q1: How do I confirm this head rotor (7123-359M / 7180-578M) fits my fuel injection pump?

A: To ensure compatibility, please check the part number stamped on your original head rotor. It should be either 7123-359M or 7180-578M. You can also verify by looking for the rotor number 344M. If you are unsure, please contact us with the model of your injection pump and engine for expert assistance.

Q2: What is the recommended installation procedure for this head rotor?

A: Installation should be performed by a qualified diesel technician. The process involves carefully disassembling the fuel injection pump, cleaning the housing, and precisely fitting the new rotor. It is critical to maintain absolute cleanliness to prevent contamination. We recommend consulting the pump’s service manual for specific torque settings and timing procedures.

Q3: What maintenance is required after installing a new head rotor?

A: After installation and initial startup, check for any fuel leaks around the pump housing. It is good practice to replace the fuel filter and ensure the fuel system is free of air. For long-term performance, use high-quality, clean diesel fuel and adhere to the engine manufacturer’s recommended service intervals for the fuel injection system.
