561-15-47210 Solenoid Valve for Komatsu WA200-1 WA300-1 WA400-1

561-15-47210 Solenoid Valve for Komatsu Wheel Loader

The 561-15-47210 / 5611547210 solenoid valve is used for Komatsu equipment hydraulic or transmission control system applications. Public parts references list this part as a Komatsu VALVE - SOLENOID, and supplier references commonly associate it with Komatsu wheel loader applications.

This solenoid valve should be selected by the original valve marking and physical configuration, not by model name alone. Komatsu machines may vary by production version, transmission control valve layout, connector type, voltage, wiring harness and previous repair history. Final fitment should be verified before ordering.

Cross Reference Numbers

Common reference numbers may include 561-15-47210 and 5611547210. Related public references may also include 568-15-17210, 5681517210, 17A-15-17270, 17A-15-17271, 714-10-16951 and 714-07-16730.

These numbers should be treated as reference information only. Solenoid valves with similar numbers may still differ in connector shape, voltage, valve body marking, mounting style or control valve application. Please compare the old valve before purchase.

Application and Fitment Reference

This Komatsu 561-15-47210 solenoid valve is commonly referenced for wheel loader applications such as WA200-1, WA300-1, WA350-1, WA380-1 and WA400-1. Some public references also mention WA500, WA800 and HD785 applications.

The model list should be used as a fitment reference, not a universal guarantee. Before purchase, compare the old valve body marking, connector type, wiring plug, mounting position, voltage and machine serial number.

Common Failure Symptoms

• Delayed hydraulic or transmission response: machine response may become slow or unstable during operation.

• Intermittent control issue: the valve may work sometimes and fail when vibration, heat or connector movement occurs.

• Electrical fault symptoms: loose pins, damaged wiring, poor ground or low voltage may imitate solenoid valve failure.

• Oil contamination: dirty oil may restrict valve movement or cause sticking.

• Warning or control abnormality: related system warning symptoms should be checked before replacing the valve.

Troubleshooting Before Replacement

• Check the original valve marking and connector type before ordering a replacement.

• Inspect the connector for oil contamination, corrosion, loose pins or damaged locking tabs.

• Check wiring harness condition, ground connection and power supply.

• Inspect oil condition and replace filters if contamination is present.

• Confirm whether the issue is caused by the solenoid valve, control circuit, wiring or oil contamination.

Installation and Maintenance Notes

• Stop the engine and release system pressure before removal.

• Disconnect electrical power before unplugging the solenoid connector.

• Clean the valve mounting area to prevent contamination from entering the system.

• Do not pull the wire harness directly; release the connector lock first.

• Install the valve carefully and confirm the connector is fully locked.

• After installation, check for leakage, warning symptoms and stable machine response under light-load operation.

Fitment Check Before Ordering

To reduce wrong orders, please send the machine model, machine serial number, old valve marking, connector photo, mounting photo and full valve body photo before quotation.
