Mercury Hydraulic Valve Lifter (8118441)

Mercury Hydraulic Valve Lifter (8118441)

The Mercury Hydraulic Valve Lifter (8118441) is a critical engine component in Mercury marine engines that ensures quiet, stable, and accurate valve operation. In Mercury engines, the hydraulic lifter automatically compensates for play between the camshaft and the valve system, balances valve clearance with oil pressure, and minimizes mechanical noise. This ensures stable engine idle speed and consistent performance.

This hydraulic valve lifter, coded 8118441, is manufactured from durable materials suitable for high speed, continuous load, and lubrication conditions. Thanks to its precise internal mechanism, it maintains valve clearance adjustment without requiring manual intervention. Worn or malfunctioning lifters can cause rattling noises, irregular operation, power loss, and long-term damage to the valve train; therefore, replacing them with the correct part during maintenance and overhaul is of great importance.
