Yanmar 729237-51350 Fuel Injection Pump – 4TNV94/4TNV98 Compatible, 175 Bar Pressure, 100% Bench Tested for Excavator & Industrial Diesel Applications

We are a professional diesel fuel system manufacturer specializing in mechanical fuel injection pumps, common rail injectors, fuel injector assemblies and complete diesel engine fuel system components.

With years of experience supplying global engine repair companies, construction machinery distributors and agricultural equipment maintenance providers, we understand that fuel system reliability directly affects engine power, fuel consumption and operating downtime.

Our Yanmar 729237-51350 fuel injection pump is specially developed for Yanmar 4TNV94 and 4TNV98 diesel engines, widely used in Yanmar Vio50, Vio55 excavators, compact loaders, forklifts and other small construction equipment.

This mechanical diesel injection pump integrates precise fuel delivery control, stable injection timing and high-pressure fuel supply functions. With a rated working pressure of approximately 175 Bar, it ensures consistent fuel injection quantity and atomization performance under different engine operating conditions.

Before shipment, every pump is tested on professional calibration equipment to verify:

• Fuel delivery accuracy
• Injection pressure stability
• Leakage performance
• Mechanical operation condition
• Overall working reliability

Our goal is to provide repair companies with a reliable replacement solution that reduces repeated maintenance and improves equipment uptime.
