Lycoming 18B23885 Front Crankshaft Bearing is a precision-engineered internal engine component designed for use in compatible Lycoming aircraft piston engines. The front crankshaft bearing provides support and alignment for the forward section of the crankshaft, allowing smooth rotational movement while carrying the operational loads generated during engine operation.

The front crankshaft bearing is a critical component of the engine's rotating assembly, maintaining proper crankshaft positioning and ensuring consistent clearance between the crankshaft and crankcase. Correct bearing operation supports effective lubrication, reduces friction, and helps protect the crankshaft from premature wear.

Manufactured to Lycoming specifications, the 18B23885 bearing is designed to withstand continuous mechanical loading, engine vibration, temperature variations, and the demanding conditions present inside aircraft piston engines. Precision dimensions ensure proper fitment and reliable performance throughout the engine service period.

The front crankshaft bearing should be inspected during engine overhaul, crankshaft servicing, or whenever the rotating assembly is disassembled. Replacement is recommended when wear, scoring, overheating, corrosion, or improper clearance is identified to maintain proper engine reliability and continued airworthiness.
