This magnetic coil is an electromechanical component that controls the opening and closing of a hydraulic valve spool. It is installed on the valve bank within the host tractor's hydraulic system, converting an electrical control signal into a linear mechanical force that shifts the spool. A failed coil results in a non-responsive or sluggish hydraulic function, such as a loader or implement circuit that fails to engage or hold position. As an original-manufacturer part, the coil is wound to the exact resistance and current draw specified for the valve assembly, ensuring the solenoid's magnetic field strength matches the spring return force for consistent actuation timing. When replacing, verify the electrical connector orientation and torque the mounting nut to specification to prevent coil movement and wire chafing.
