Product SpecificationsPart Numbers: SA-4269-24, 600-815-7550Voltage: 24V DC (nominal operating range: 21V - 28V)Solenoid Type: Pull-type stop solenoid (spring return to extended position)Duty Cycle: Intermittent (energized when engine runs, de-energized at shutdown)Terminal Type: Single wire (ground through mounting bracket)Mounting: 2-bolt flange mountPlunger Action: Energized = retracted / De-energized = extended (spring return)Material: Steel body with composite plastic coil coverCompatible with Komatsu EnginesFor Komatsu S4D95L (4-cylinder, naturally aspirated)For Komatsu 4D95 series (4-cylinder diesel)For Komatsu 4D102 series (4-cylinder diesel)For Komatsu 6D102 series (6-cylinder diesel)Compatible with Komatsu EquipmentExcavators: PC60-7, PC75UU-2, PC75UU-3, PC75US-3, PC78US-6, PC128US, PC138US, PC200LC-6, PC228UU-1, PC228US-2Wheel Loaders: WA100, WA150, WA320-5Fuel Shutoff Solenoid Function for Komatsu EnginesNormal Operation (Key ON): 24V power energizes the SA-4269-24 solenoid coil. Magnetic field retracts the plunger (pulls inward). Fuel rack moves to RUN position. Engine runs for Komatsu.Shutdown (Key OFF): Power removed from 600-815-7550 solenoid. Internal spring extends the plunger (pushes outward). Fuel rack moves to STOP position. Fuel flow blocked. Engine stops within 3 seconds.Safety Feature: Prevents engine runaway by cutting fuel when key is turned off or electrical power fails for Komatsu excavator or wheel loader.What's IncludedOne 24V fuel shut off solenoid with cross-referenced part numbers SA-4269-24 and 600-815-7550. Includes pre-assembled plunger and return spring. No mounting bolts, wire connector, or linkage hardware is included. This is a replacement for the original for Komatsu stop solenoid on 4D95, 4D102, and 6D102 engines in PC60-7, PC75UU-3, PC78US-6, PC128US, PC138US, PC200LC-6, PC228UU-1, PC228US-2 excavators and WA100, WA150, WA320-5 wheel loaders. Professional mechanic installation recommended.

• 📋 Part Number Cross-Reference - 600-815-7550 fuel solenoid replaces for Komatsu numbers SA-4269-24 and 600-815-7550. The 24V stop solenoid is original equipment for Komatsu 4D95, 4D102, and 6D102 series engines. Before ordering this fuel shutoff solenoid, verify your old unit matches one of these part numbers.
• 🚜 For Komatsu Engine Compatibility - SA-4269-24 shutdown solenoid fits for Komatsu S4D95L, 4D95, 4D102, and 6D102 diesel engines. These engines power PC60-7, PC75UU-3, PC75US-3, PC78US-6, PC128US, PC138US excavators. Also fits WA100, WA150, WA320-5 wheel loaders and PC200LC-6, PC228UU-1, PC228US-2 excavators with compatible engines.
• 🔋 Voltage Verification - SA-4269-24 fuel shut off solenoid operates on 24V DC only. Before ordering this 24V stop solenoid for Komatsu excavator, verify your machine uses a 24V electrical system.
• ⛽ Engine Shutdown Function - 600-815-7550 fuel stop solenoid cuts fuel supply when de-energized. When you turn off the ignition for Komatsu PC60-7, power is removed from the 24V solenoid. The spring-loaded plunger extends to block the fuel rack, stopping the engine within 3 seconds.
• 🔧 Installation Note - Installing this 600-815-7550 24V fuel solenoid requires basic hand tools. The stop solenoid mounts with two bolts on the injection pump. Connect positive wire to the single terminal (body grounds through mounting bracket). Test solenoid operation by applying 24V - plunger should retract with an audible click for Komatsu engine. Do not run engine until you verify proper plunger movement.
