Wheel Steer Solenoid Coil (19.2mm) suitable for JCB - 25/222645

Technical Specification and Compatibility

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.

Part Number: 25/222645
Voltage: 13 VDC
Power: 36 W
Bore Diameter (FI): 19.2 mm
Height (H): 55 mm
Connector: DEUTSCH 2-pin

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.

Features of the 25/222645 Coil

GX-OEM Quality: Guarantees electrical parameters (13V, 36W) and durability identical to the original.
Precise Dimensions: A perfect 19.2 mm bore and 55 mm height ensure correct fitment on the valve stem.
Deutsch Connector: High-quality, sealed 2-pin Deutsch connector, resistant to moisture, dust, and vibration.
Crucial for Steering: Essential for the correct operation of AWS systems, including "crab" and 4-wheel steer modes.

Application in machinery

Brand Type / Series / Model
JCB Backhoe Loaders: 2CX, 2DX, 3CX, 3CX COMPACT, 3DX, 4CX, 4/4C/4CN, 5CX, 210, 212, 214, 215, 217
JCB Telehandlers (Loadall): 505, 506, 508, 509, 512, 525, 526, 527, 530, 531, 532, 533, 535, 536, 538, 540, 541, 542, 550, 560
JCB Wheeled Excavators: HYDRADIG 110W, HYDRADIG 150W

The list above is for reference. It is crucial to verify the dimensions (19.2mm bore, 55mm height) and connector type (Deutsch).

Related Parts and Hardware

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.

⚠️ Safety Warning

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.

Part Role in the Machine and Failure Diagnostics

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").

  • › No response from the steering mode switch (e.g., "crab" steer won't engage).
  • › Machine is stuck in one steering mode.
  • › Blowing the fuse for the steering circuit (short circuit in the coil).
  • › No audible "click" from the coil when voltage is applied.
  • › Visible cracking or melting of the coil housing.

🔧 Expert Guide: Key Installation Tips

  1. Verify Dimensions: Before installation, ensure the valve stem diameter matches the coil bore (19.2 mm).
  2. Check Voltage: Confirm the machine's system voltage is 13VDC (standard 12V system). Applying 24V will instantly burn it out.
  3. Check Connector: Ensure the machine's harness plug is a 2-pin DEUTSCH and is in good condition (no corrosion).
  4. Clean Installation: Clean any dirt or rust off the valve stem before sliding the new coil on.
  5. Check Spool: Before fitting the coil, manually check (e.g., with a small screwdriver) that the hydraulic valve spool is not mechanically seized.

Frequently Asked Questions (FAQ)

What is "crab steer"?

"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.

Why is the coil rated 13VDC and not 12V?

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.

How is this coil different from a reverser (transmission) coil?

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.
