Lycoming 14D23908 Piston is a precision-engineered engine component designed for use in compatible Lycoming aircraft piston engines. The piston is a critical part of the reciprocating engine assembly, converting combustion pressure into mechanical force that drives the crankshaft and produces engine power.

The piston operates inside the cylinder barrel, moving through the intake, compression, power, and exhaust cycles while maintaining proper sealing through the piston ring assembly. Accurate piston fit and movement are essential for maintaining compression, controlling oil consumption, and ensuring efficient combustion performance.

The 14D23908 piston is an alternative replacement for LW-10207-S and is manufactured to Lycoming specifications for reliable aircraft engine service. Its design is intended to withstand the high temperatures, combustion pressures, vibration, and continuous reciprocating loads experienced during engine operation.

Pistons are inspected during cylinder maintenance and engine overhaul procedures for wear, scoring, cracking, dimensional changes, and ring groove condition. Replacement of worn piston components helps restore proper cylinder performance, compression efficiency, and overall engine reliability.
