Corteco Engine Crankshaft Pulley Harmonic Balancer

The Corteco crankshaft pulley and harmonic balancer line is an OEM-quality replacement for the pulley that mounts to the front of the engine crankshaft. It drives the accessory belt system and helps damp torsional vibration from the crankshaft. Depending on the part, it may also be called a crankshaft damper, vibration damper, or crank pulley.

Key Features:

• Drives the serpentine or accessory belt that powers components such as the alternator, water pump, and power steering pump
• Helps damp crankshaft torsional vibration, reducing stress on the engine and its drive components
• Typically built around a bonded rubber element between the hub and the outer ring
• Made by Corteco, a supplier of original-equipment sealing and vibration-control components
• Designed to match the form, fit, and function of the original part

Replacing a worn or damaged pulley or balancer helps keep the accessory drive running smoothly and quietly. It also helps protect the crankshaft and bearings from excess vibration. The line includes several part numbers, each made for its own application.
