1753ES-12A3UC5B1S1 SA-4561-12 Shutoff Solenoid for Yanmar B22 B27-2 B50-2 Excavator | 12V Fuel Stop Valve | Fixing Mini-Excavator Engine Shutdown Failures

Optimize Mini-Excavator Performance with Reliable Fuel Control

Furthermore, the 1753ES-12A3UC5B1S1 fuel shutoff solenoid acts as a critical safety link in your excavator’s powertrain. Because the valve converts electrical signals into a powerful mechanical pull to stop the fuel flow, it directly dictates your machine’s operational safety. Therefore, replacing a sticky or burnt-out solenoid with our tested aftermarket unit restores the factory-standard response required for precision work in tight spaces.

Technical Specifications

Broad Compatibility for Yanmar Compact Machinery

In addition to the popular B27-2 series, this part number supports a wide variety of Yanmar B-series compact excavators. Specifically, our engineering team has verified fitment for B22 and B50 models requiring the SA-4561-12 configuration. Note: However, we always recommend checking the wire connector and mounting flange of your original unit to ensure a perfect “plug-and-play” installation for your specific machine serial number.

Superior Quality for High-Vibration Work Environments

First, our factory selects premium-grade copper wiring that resists insulation melting during prolonged engine operation in cramped engine bays. Subsequently, every 1753ES-12A3UC5B1S1 unit undergoes 100% pull-force and electrical continuity testing in our quality lab. As a result, our solenoids withstand the extreme vibrations and thermal spikes typical of mini-excavator compartments. Moreover, our 6-month warranty protects your purchase, ensuring your equipment remains safe and controllable in the field.
