Lycoming 18E23886 Crankshaft Bearing is a precision-engineered internal engine component designed for use in compatible Lycoming aircraft piston engines. The crankshaft bearing provides a controlled low-friction support surface between the crankshaft and engine crankcase, allowing smooth rotation while carrying the significant loads generated during engine operation.

The crankshaft bearing is a critical element of the engine's rotating assembly, maintaining proper crankshaft alignment and supporting consistent oil flow around the bearing surface. Correct bearing clearance is essential for effective lubrication, heat management, reduced friction, and long-term protection of the crankshaft and related engine components.

Manufactured to Lycoming specifications, the 18E23886 bearing is designed to withstand continuous cyclic loading, vibration, high operating temperatures, and the demanding conditions found inside aircraft piston engines. Precision manufacturing ensures accurate fitment and reliable performance throughout the engine service life.

The crankshaft bearing should be inspected during major engine overhaul or crankshaft service procedures. Replacement is recommended whenever excessive wear, scoring, overheating, corrosion, or incorrect bearing clearance is detected to restore proper engine operation and maintain airworthiness.
