Other industrial equipment for Mitsubishi L Series engines
Normal Operation (Key ON): 12V power energizes the SA-3725-12 solenoid coil. Magnetic field retracts the plunger (pulls inward). Fuel rack moves to RUN position for Mitsubishi injection pump. Engine runs.
Shutdown (Key OFF): Power removed from 30A87-20404 solenoid. Internal spring extends the plunger (pushes outward). Fuel rack moves to STOP position. Fuel flow blocked for Mitsubishi L3E engine. Engine stops within 3 seconds.
Safety Feature: Prevents engine runaway by cutting fuel when key is turned off or electrical power fails on your diesel engine.
One 12V shut off solenoid with cross-referenced part numbers SA-3725-12, 30A87-20404, 30A87-20400, 30A87-10044, PJ7415748, and others listed. Includes pre-assembled plunger and return spring. No mounting bolts, wire connector, or linkage hardware is included. This is an replacement for the original for Mitsubishi stop solenoid on L Series engines (S3L, S4L, L3E, L2E, L3P) in Volvo compact excavators, For Mahindra tractors, and other industrial equipment. Professional mechanic installation recommended.
