Lycoming LW-13322 Lower Intake Valve Spring Seat is a precision-machined engine component designed to support and properly position the intake valve spring within compatible Lycoming aircraft engines. Installed at the base of the intake valve spring assembly, it provides a stable seating surface that ensures correct spring alignment and consistent valve train operation.

The lower valve spring seat plays an essential role in distributing spring loads evenly while maintaining proper positioning of the intake valve spring during every engine cycle. Accurate alignment helps ensure reliable valve seating, efficient airflow into the combustion chamber, and smooth operation of the valve train under varying engine speeds and operating conditions.

Manufactured to Lycoming specifications, the LW-13322 is engineered from durable materials capable of withstanding the continuous mechanical stresses, vibration, and elevated temperatures encountered in aircraft piston engines. Its precision dimensions contribute to proper valve geometry and long-term engine reliability.

The lower intake valve spring seat is commonly inspected during cylinder maintenance and engine overhaul. Replacement is recommended whenever wear, deformation, corrosion, or other damage is detected to maintain proper valve train performance and support continued engine airworthiness.
