Lycoming LW-11796 Outer Valve Spring is a genuine replacement engine valve spring designed for compatible Lycoming aircraft piston engines. As the outer spring in a dual valve spring assembly, it provides the necessary closing force to ensure proper valve operation throughout the engine's operating range.

The outer valve spring works together with the inner valve spring to maintain continuous contact between the valve train components, allowing the intake or exhaust valve to close securely after each combustion cycle. Proper spring tension is essential for maintaining valve timing accuracy, preventing valve float at higher engine speeds, and ensuring efficient engine performance.

Manufactured to Lycoming specifications, the LW-11796 valve spring is produced from high-strength spring steel and heat-treated for durability under repeated cyclic loading. It is designed to withstand the high temperatures, vibration, and mechanical stresses encountered during continuous aircraft engine operation.

The outer valve spring should be inspected during cylinder maintenance and engine overhaul for signs of fatigue, corrosion, distortion, or loss of spring tension. Replacing worn valve springs helps restore proper valve train performance, improve engine reliability, and support continued airworthiness.
