Description
When your tractor keeps running after you turn the key off, that’s your diesel stop solenoid telling you it’s done for the day—even if you’re not. This diesel stop solenoid controls the fuel supply to your engine, cutting off the diesel flow when you turn off the ignition so your tractor stops when it’s supposed to instead of continuing to run until it runs out of fuel. Having reliable engine shutdown control isn’t just convenient – it’s essential for safe operation around the farm.
What You’re Getting
- CAV-type design with single nut connection that threads right in without fuss
- 12-volt operation that works with standard tractor electrical systems
- M14 x 1.5 metric thread for secure mounting and leak-free operation
- Heavy-duty electromagnetic coil designed for agricultural environments
- Universal compatibility across multiple tractor brands and series
Built for Real Farm Work
This 12-volt CAV-type diesel stop solenoid provides reliable fuel shut-off control for a wide range of European and American tractor brands. Whether you’re using your Fiat for vineyard work, your Ford New Holland for hay production, or your John Deere for row crop farming, this solenoid handles the constant start-stop cycles that come with real farm work.
Made to Last
Robust construction withstands vibration and temperature extremes that are part of everyday tractor operation. The single nut connection design with M14 x 1.5 thread ensures secure mounting and positive fuel valve closure to prevent diesel run-on and protect injection pump systems from damage.
Installation Notes
Clean mounting threads and apply proper torque to prevent fuel leakage. Test solenoid operation by confirming fuel cut-off when ignition is turned off. Connect to ignition switch circuit for automatic operation during engine shutdown. If your old solenoid has been stuck for a while, a little penetrating oil helps with removal.
