SA399112 For Massey Ferguson 12V Fuel Shut-Off Solenoid

This high-power pull-type 12V dual-coil fuel shut-off solenoid works with Sisu / Valmet diesel engines fitted on large European farm tractors and heavy industrial machinery. When the ignition key is switched on, its pull coil moves the fuel pump linkage to the running position while the hold coil keeps it stable; turning off the key deactivates the solenoid, and an internal spring instantly resets the fuel lever to cut fuel supply and shut down the engine. Malfunction of this part may cause startup failure or failure to stop the engine after power-off. It meets the required electrical specifications, and full parameters can be checked on our dedicated spec page. This aftermarket replacement is engineered for demanding heavy-load working environments, delivering reliable long-lasting performance for high-power agricultural and industrial applications. It fits Sisu Valmet 620 and 634 series 6-cylinder turbo diesel engines, widely used on Massey Ferguson, European Case IH, Valmet and Valtra heavy tractors. It supports cross-reference part numbers including SA-3991-12, 836640253, 1912.2204 and more for convenient equipment maintenance.

FAQ Section

Q1: What symptoms indicate you need to replace this 12V dual-coil fuel shut-off solenoid?
