FAQ

1. How do I confirm if this rotor head fits my customer’s pump?

To ensure a perfect fit, you must verify the exact OE number stamped on the original rotor head. This part directly replaces numbers 7123-340R, 7180-550R, 344R, and 558A. If your customer’s part number matches one of these, the part is compatible.

2. What is the recommended installation procedure?

Installation should be performed by a qualified diesel technician. Ensure the pump housing is clean and free of debris. Lubricate the rotor head with clean diesel fuel or assembly lube before installation. Torque the retaining screws to the manufacturer’s specifications. We recommend replacing the seal kit and checking the pump timing after installation.

3. What is the typical lifespan of this rotor head?

The lifespan depends heavily on fuel quality and operating conditions. With proper installation and the use of clean, high-quality diesel fuel (including proper filtration), this high-speed steel rotor head can provide a service life comparable to OE parts, typically lasting for thousands of operating hours. Regular fuel filter changes are critical for maximum longevity.
