Overview
The Lycoming Crankshaft, part number LW-10619, is the central rotating component within the Lycoming O-235 series reciprocating piston aircraft engine. Its fundamental role is to translate the linear up-and-down motion of the pistons, transmitted through the connecting rods, into continuous rotational motion. This rotational energy is then delivered to the propeller, generating thrust, and also drives various engine accessories such as the alternator, oil pump, and magneto. As a critical structural component, the LW-10619 crankshaft is engineered to withstand immense cyclic loads, torsional stresses, and high temperatures inherent to internal combustion engine operation.Specifications
