FAQ

Q1: What is the difference between the X4, X5, X6, and X7 rotor heads?

A: These numbers typically refer to different size or design variations within the Yanmar fuel pump family, often related to plunger diameter or delivery valve configuration. It is critical to match the exact number (X4, X5, X6, or X7) from your existing pump’s rotor head to ensure proper fuel delivery and timing. If you are unsure, please provide your pump model and serial number for verification.

Q2: Is special tooling required for installation of this repair kit?

A: Yes, installing a rotor head repair kit requires specialized knowledge and tools, including a fuel pump test bench and precise measuring equipment. We recommend that installation be performed by a qualified diesel fuel injection technician. Improper installation can lead to pump failure or engine damage.

Q3: What is the typical lifespan of this repair kit after installation?

A: The lifespan depends heavily on fuel quality, operating conditions, and maintenance schedules. Under normal operating conditions with clean fuel and proper filtration, a high-quality rotor head repair kit can restore pump performance for thousands of hours. Regular inspection of the fuel system is recommended to maximize service life.
