FAQ

Q1: How do I verify if this 7185-044L head rotor fits my fuel injection pump?
A1: To confirm fitment, please check the model number on the nameplate of your injection pump. This part is specifically designed for pumps that require a 4/7R rotor configuration. If you are unsure, provide us with the pump model and serial number, and our technical team can assist in verifying compatibility.

Q2: What is the recommended installation procedure for this head rotor?
A2: Installation should be performed by a qualified diesel technician. It is critical to clean the pump housing thoroughly before installation. Lubricate the rotor with clean diesel fuel or assembly oil during installation. Ensure the drive shaft is aligned correctly to prevent binding. Torque all retaining screws to the manufacturer’s specifications to avoid damage.

Q3: What are common signs of a failing head rotor that would require replacement?
A3: Common symptoms include hard starting, engine misfiring, reduced power, excessive black smoke, and irregular engine idle. A worn head rotor can also cause fuel leaks from the pump housing. If you experience these issues, especially after inspecting filters and lines, the head rotor assembly should be tested or replaced.
