A component related to the engine shutdown control

On an agricultural tractor, the engine shut-off solenoid valve is one of the components that enable the engine to be shut off electrically. Its general function is to ensure the controlled shutdown as specified by the system installed on the machine. For this reason, this family of parts must be replaced with precise identification, as a mere external resemblance is not always sufficient.

In common usage, you may also come across the term “engine shut-off solenoid.” The term used may vary depending on workshop practices or the available documentation, but the goal remains the same: to find the part number that matches your tractor and its specific installation.

Application identified on CASE Magnum tractors

This part number is associated with CASE Magnum tractors from the series listed in the compatibility chart provided with this product sheet. It applies to the Magnum 7110, Magnum 7120, Magnum 7130, Magnum 7140, and Magnum 7150. These exact model designations are important because they help prevent the compatibility from being extended to other Magnum models not listed.

For both repair technicians and farmers, this specificity is useful when repairing a malfunctioning stop control, performing a preventive replacement of a worn part, or simply bringing an existing installation up to code. Best practice is to rely on part number J921978 and the exact tractor identification.

Useful guidelines for selecting the correct part number

The most straightforward selection criterion here is part number J921978. If this part number matches your needs, it will help you distinguish this solenoid valve from other engine shut-off controls that look similar but are designed for different setups. Also check the complete model designation of your machine, as it appears on your CASE Magnum.

When replacing an engine shut-off solenoid valve, it is also helpful to compare the removed part with the new one, taking into account its location on the tractor. This visual inspection supplements the part number; it does not replace model-based identification. If your machine has undergone previous modifications, an additional check following the manufacturer’s procedure is recommended.

When to Consider Replacement

Replacement of this part is generally considered when the engine shut-off command no longer functions normally, or when a repair of the control circuit requires using a clearly identified part. In this type of repair, the goal is to avoid confusion between several similar part numbers.

Before confirming your order, please take the time to verify part number J921978 and the exact model designation of your CASE Magnum tractor. This is the surest way to select the correct engine shut-off solenoid valve for your application.
