Failure Symptoms

The first indication of a faulty seat adjustment valve is often a seat that slowly sinks or drifts from its set position. If left unaddressed, the seat may become completely unresponsive to adjustment controls, leading to operator discomfort and reduced productivity.

Installation Tip

Ensure the cabin's pneumatic or hydraulic system is properly depressurized before disconnecting lines. Avoid cross-threading the connection fittings when installing the new valve.

Service Note

Inspect the seat adjustment mechanism and associated pneumatic or hydraulic lines for leaks or damage when replacing the control valve.
