VALVE CONTROL MOTOR FOR JOHN DEERE AL218230

The AL218230 spool control motor is an electrical component designed for John Deere applications on several tractors in the 6M, 6R, 7R, and 8R series. It is used to control the hydraulic valve and is identified primarily by its part number, AL218230, which should be verified on the existing part or in the machine’s documentation.

Role of this motor in the hydraulic control system

This type of motor contributes to the electric actuation of the hydraulic spool valve. In an electrohydraulic system, it transmits the control signal associated with a circuit function to enable the operation of auxiliary outputs and equipment that utilizes the tractor’s hydraulic system.

On a machine equipped with in-cab controls, this component influences the valve’s response when the operator activates a function. Its role, therefore, pertains to controlling the valve itself, rather than the entire hydraulic circuit or an adjacent mechanical component.

When a control motor malfunctions, symptoms may include erratic response, intermittent operation, or the inability to properly activate a hydraulic function. These symptoms should be evaluated in conjunction with the condition of the wiring harness and connections before replacement.

Affected John Deere Applications

Part number AL218230 corresponds to John Deere applications found on tractors in the 6M, 6R, 7R, and 8R series. Detailed model designations for compatible models are listed immediately following this description, including distinct variants such as the 6155RH.

This series-based identification helps narrow down the search, but final identification must always be based on the exact model and the part number installed. This is particularly useful for tractors that look similar but differ in their hydraulic systems.

How to Identify the Correct Part

The first step is to check part number AL218230. Note it directly from the removed component if it is legible, or confirm it using your tractor’s identification information. This step helps avoid confusion with other electrical components related to the hydraulic system.

Next, verify the function of the part you’re looking for: it must indeed be a hydraulic spool control motor. Do not confuse it with a solenoid valve, a sensor, a wiring harness, or a complete spool assembly. On some machines, several nearby components work together around the same unit, which is why it’s important to identify the part precisely by location and part number.

If the tractor or hydraulic block has been modified previously, it is advisable to double-check the part’s application before ordering.

When to Consider Replacement

Replacement of this component may be considered when a valve control no longer responds normally, when operation becomes erratic, or when a hydraulic function no longer engages as expected. These symptoms do not necessarily indicate the same cause, but they often point to the need for a targeted inspection of the electrohydraulic control system.

To proceed with confidence, refer to part number AL218230 and the specific model of your John Deere. If these details match, you can more confidently select the control motor suited to your application.

FAQ — Frequently Asked Questions

What is the AL218230 valve control motor used for?

The AL218230 motor is used to electrically actuate the hydraulic control valve. It controls the hydraulic functions operated from the cab, particularly the auxiliary outlets and implement movements powered by the tractor’s hydraulic system.

How can I verify that part number AL218230 is the correct one for my tractor?

The most reliable way to verify this is to check the part number AL218230 on the existing part and then match it to the exact tractor model. You should also confirm that it is indeed the control motor for the hydraulic spool valve, and not a solenoid valve or a complete spool valve assembly.

Is this motor compatible with the John Deere 6110M, 6155RH, and 7310R?

Yes, these three models are among the applications listed for part number AL218230. The 6110M, 6155RH, and 7310R are among the listed John Deere models, along with other tractors from the 6M, 6R, 7R, and 8R series.

What signs might indicate that this control motor needs to be replaced?

Replacement may be necessary if a spool valve fails to respond, operates intermittently, or responds erratically. Before making a decision, it is advisable to check the condition of the connectors, the wiring harness, and the power supply to the affected electrohydraulic system.
