Lycoming 62388 Valve Stem Cap is a precision-engineered valve train component designed for installation on compatible Lycoming aircraft piston engines. The valve stem cap provides a hardened contact surface between the valve stem and rocker arm, helping distribute operating loads and reduce wear within the valve train assembly.

The valve stem cap plays an important role in maintaining proper valve train geometry by protecting the end of the valve stem from direct contact with the rocker arm. This helps minimize wear, maintain correct valve clearance, and support consistent valve operation throughout the engine's operating cycle.

Manufactured to Lycoming specifications, the 62388 cap is designed to withstand repeated mechanical contact, high temperatures, vibration, and cyclic loading experienced in aircraft piston engine operation. Its precision dimensions ensure proper fit and reliable performance within the valve mechanism.

The valve stem cap should be inspected during cylinder maintenance and valve train servicing for signs of wear, deformation, cracking, or surface damage. Replacement of worn components helps maintain proper valve clearance, reduce friction, and support reliable engine performance.
