FAQ

Q: Is this fuel injection pump a direct bolt-on replacement for the Yanmar 4TNV106 engine?

A: Yes, this pump (723945-51300) is a direct OEM replacement. It is designed to bolt directly onto the 4TNV106 engine block and connect to the existing fuel lines and governor linkage without modifications. Please confirm your engine’s serial number to ensure it matches the 4TNV106 family.

Q: What is the recommended installation procedure for this pump?

A: Installation should be performed by a qualified diesel mechanic. It is critical to prime the pump with clean diesel fuel before starting the engine to prevent dry running. Ensure all fuel lines are clean and the timing marks on the pump gear and engine housing are correctly aligned. We recommend replacing the fuel filter at the same time.

Q: How should I maintain this injection pump for optimal longevity?

A: To maximize the life of the pump, always use clean, high-quality diesel fuel. Regularly replace the fuel filter and water separator as per the engine manufacturer’s schedule. If the machine is stored for long periods, running the engine and stabilizing the fuel will prevent internal corrosion. If you notice a loss of power or hard starting, have the pump timing and pressure checked by a specialist.
