Failure Symptoms

The initial symptom of a failing seat adjustment valve is difficulty in moving the seat or a jerky adjustment motion. If ignored, the valve may start to leak internally, causing the seat to slowly drift down or fail to lock in position. This can lead to operator discomfort and reduced driving safety.

Installation Tip

Ensure the hydraulic system is depressurized before disconnecting lines to the valve. Be careful not to cross-thread the hydraulic fittings when installing the new valve.

Service Note

Inspect the hydraulic lines and the seat cylinders for leaks or damage when replacing the control valve.
