Good To Know
Q: Will this solenoid work on my CAT 3208 engine? A: This solenoid is designed for Caterpillar CAT 3208 and 3412 engines, but verify your engine's serial number and mounting configuration to confirm fit before purchase.
Q: How do I know if my solenoid is faulty? A: If the engine fails to shut off or shutoff is sluggish, suspect the solenoid coil or plunger. Test with a 12V supply to see if the plunger retracts cleanly.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
