Corteco 49444031 Crankshaft Pulley with Vibration Damper

The Corteco 49444031 Crankshaft Pulley is a precision-engineered torsional vibration damper designed to effectively decouple the belt drive system from the crankshaft. This OEM-quality component serves a dual purpose: it drives essential engine accessories while simultaneously absorbing engine shock and vibration to ensure smooth, quiet operation.

Key Features:

• Integrated harmonic balancer reduces crankshaft vibration and stress on adjoining components
• 159mm diameter with 6PK belt configuration and 5 ribs for optimal belt engagement
• Includes mounting manual with precise torque specifications for proper installation
• Manufactured to OEM standards for reliable fit and long-lasting performance
• Cross-references to BMW OEM part number 11238602800

When a vibration damper fails, symptoms typically include squealing noises that sound like a slipping belt, caused by the internal rubber ring drying out and cracking. The Corteco 49444031 restores proper timing mark position, controls crankshaft vibration, and ensures all belt-driven accessories operate correctly. By minimizing vibration transmission, this pulley extends the lifecycle of surrounding engine components and maintains optimal engine performance.
