A high-quality 25/222645 solenoid coil, GX-OEM quality, for JCB machines. This is a key component of the solenoid valve responsible for wheel steer mode control (AWS - All Wheel Steer), including engaging the "crab" steer position. It fits 3CX/4CX backhoe loaders, a wide range of telehandlers, and Hydradig wheeled excavators.
By choosing GX-OEM parts, you are choosing uncompromising first-assembly quality. Our products are made with the highest precision, guaranteeing a perfect fit and parameters identical to the original. This is the best investment in the long and trouble-free operation of your machine.

The list above is for reference. It is crucial to verify the dimensions (19.2mm bore, 55mm height) and connector type (Deutsch).
The 25/222645 coil is fitted onto a hydraulic solenoid valve. When replacing, we recommend checking the Deutsch plug on the machine's harness and the valve stem (spool) for any signs of jamming.
Failure of the wheel steer solenoid coil leads to a loss of ability to change steering modes (e.g., being stuck in "crab" or 4-wheel steer). This poses a serious safety hazard, preventing normal maneuvering and road travel, and can lead to a collision.
The 25/222645 coil is an electromagnet. When it receives an electrical signal (13VDC, 36W) from the switch in the cab, it generates a strong magnetic field. This field moves the spool inside the solenoid valve, which opens or closes oil passages. In this specific application, it directs hydraulic oil to the rear axle steering cylinders, allowing the steering mode to be changed (e.g., 2-wheel steer, 4-wheel steer, "crab").

"Crab steer" is a function on AWS (All Wheel Steer) machines where all four wheels turn in the same direction. This allows the machine to move diagonally (like a crab), which is useful for working in tight spaces or grading.
This is a standard rating for coils in a 12V system. The charging system (alternator) in a running machine produces ~13-14V, so coils are designed to operate continuously at this voltage.
Primarily by its dimensions. Transmission/reverser coils typically have a smaller bore diameter (e.g., 16 mm). This coil (25/222645) has a large 19.2 mm bore and is specific to hydraulic valves, often for steering control.
