Woodward 419100 Fuel Stop Solenoid Assembly

The Woodward 419100 fuel stop solenoid is a 12V DC electromechanical valve designed to control fuel flow for engine shutdown on Thermo King transport refrigeration units. It functions as a normally closed energized-to-run solenoid, providing precise fuel cutoff when de-energized. This assembly replaces Thermo King OEM part numbers 41-9100, 419100, 42-100, 42-0100, 41-6383, 41-4306, and 1500-3076. It cross-references to Yanmar engine part numbers 129486-77952 and 129486-77954. The solenoid is compatible with Yanmar industrial engines including 3TNE72, 3TNA72, 4TNE84, and 4TNE88 series, as installed in Thermo King TK2.49, TK3.74, TK3.88, TK3.95, TK4.82, TK4.86, KD, MD, RD, SL, and APU/Tripac unit models. Construction features a metal housing with integrated electrical connector for direct mounting on the engine fuel injection pump.
