Lycoming LW-11625 Piston Pin Plug is a genuine replacement engine component designed for installation at the ends of the piston pin in compatible Lycoming aircraft piston engines. The plug serves as a protective barrier between the piston pin and the cylinder wall, helping prevent direct metal-to-metal contact during engine operation.

The piston pin plug is an essential part of the piston assembly, supporting proper alignment of the wrist pin while protecting the cylinder from potential damage caused by lateral piston pin movement. Its lightweight yet durable construction contributes to reliable engine performance without significantly affecting the reciprocating mass of the piston assembly.

Manufactured to Lycoming specifications, the LW-11625 is engineered to withstand the high temperatures, combustion pressures, and continuous reciprocating motion encountered within aircraft piston engines. Precision dimensions ensure proper fit within the piston assembly and dependable performance throughout the engine's service interval.

The piston pin plug should be inspected whenever cylinders or pistons are removed during engine maintenance or overhaul. Replacement is recommended if wear, cracking, deformation, or other damage is observed to help maintain proper piston assembly integrity and protect critical engine components.
