Overview
The **Lycoming Crankshaft Plug Retainer (P/N LW-14792)** is a vital, small component designed to secure the internal plug at the aft end of the engine crankshaft. This retainer plays a critical role within the engine's lubrication and structural integrity systems, preventing the egress of oil from the crankshaft's internal passages and ensuring that the crankshaft plug remains properly seated under dynamic operating conditions. It is an essential part of the Lycoming O-235 series engine, contributing to the reliable operation of the propeller drive and internal oil circulation.Specifications
