729564-51310 Yanmar Fuel Injection Pump – 2-Pin Connector, 140 Bar Stable Pressure, High Reliability Diesel Pump Replacement

Professional Yanmar 729564-51310 Fuel Injection Pump Supplier for Mini Excavator & Generator Applications

I am a diesel fuel system engineer specializing in supplying replacement fuel injection components for construction machinery, agricultural equipment and industrial diesel engines.

The Yanmar 729564-51310 fuel injection pump is a precision mechanical fuel pump developed for compatible Yanmar diesel engines. It provides stable fuel delivery, accurate injection timing control and reliable operating performance for small diesel-powered equipment.

This fuel pump is commonly used in Yanmar 2TNV70 and 2TNV74 diesel engine applications, including mini excavators, garden tractors, compact machinery and generator sets. With a 2-pin electrical connector design and approximately 140 Bar rated injection pressure, it ensures consistent fuel supply under different working conditions.

During engine operation, the fuel injection pump controls the amount and timing of diesel fuel entering the combustion chamber. A worn or damaged pump may cause difficult starting, unstable idle speed, low engine power, increased fuel consumption or excessive exhaust smoke.

To help our customers reduce installation risks and maintenance downtime, every fuel pump supplied by us is inspected before shipment. We check fuel delivery performance, leakage condition and basic calibration parameters to ensure stable operation after installation.

Common Problems Caused by a Damaged Fuel Injection Pump

When the original fuel pump becomes worn, customers may experience:

Difficult Cold Starting

Insufficient fuel pressure may prevent normal diesel ignition, especially in cold environments.

Unstable Engine Idle

Incorrect fuel delivery can cause engine vibration and irregular speed.

Reduced Engine Power

Poor injection performance may reduce combustion efficiency and machine working capacity.

Increased Fuel Consumption

Incorrect fuel quantity control can lead to inefficient combustion.

Excessive Exhaust Smoke

Poor atomization and incomplete combustion may increase smoke emissions.

Replacing the fuel injection pump with a properly matched unit helps restore normal engine performance.
