244-8686 Solenoid Valve — Cat 938H 120M

This is a solenoid valve that controls the flow of hydraulic fluid or transmission oil within a machine's system, actuated by an electrical signal. It is manufactured to precise tolerances for reliable switching and sealing, ensuring proper operation unlike a worn valve that may stick or leak. Operators may experience erratic transmission shifting, loss of hydraulic function, or unexpected equipment movement when this solenoid valve fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing solenoid valve may initially cause intermittent issues, such as delayed responses or slight hesitations in hydraulic functions or gear changes. If the valve becomes stuck or fails to actuate, it can lead to a complete loss of the controlled function or erratic operation. The worst-case scenario involves loss of control over critical machine functions, posing a safety risk.

Installation Tip

Always disconnect the battery before working on electrical components like solenoid valves to prevent short circuits. Ensure the new valve is installed in the correct orientation as per the service manual.

Service Note

When replacing a solenoid valve, it is recommended to inspect the hydraulic filter and fluid for contamination, as debris can cause valve failure.
