Product Overview
A 12V shutdown solenoid used on Sisu/Valmet-powered tractor applications. The SA-3991-12 configuration is a strong identifier because the same engine families can appear under more than one tractor brand.
No-start, engine stopping as soon as the key is released, or failure to shut down can involve the solenoid, linkage or control voltage. Low supply voltage can prevent a healthy solenoid from completing its pull stroke.
Key Features & Performance
- Restores electrical control of the engine fuel-stop mechanism.
- Helps the engine start/run or shut down correctly when the original actuator is weak or stuck.
- Designed around the listed connector/mounting application rather than a universal solenoid.
Specifications & Reference Numbers
- Reference number(s): SA-3991-12, 836640253, 836640254; related references 836640243, 1751X-12V, 1912.2204
- Voltage: 12V
