The INA EA0168 alternator decoupler pulley is a front-end auxiliary drive component built for Mercedes-Benz applications that need controlled alternator decoupling and vibration management in tight engine bays. It supports smooth accessory drive operation in high-load engines while helping reduce stress on related FEAD components.

Key Features

• Alternator decoupler pulley for FEAD systems
• Helps manage vibration damping in compact installation spaces
• Supports accessory drive stability in high-load Mercedes-Benz engines
• OE-style replacement for select Mercedes-Benz C-Class, E-Class, GLK, ML, SL, and AMG models
• INA part number EA0168 for direct catalog identification

Detailed Description

Built under INA’s front end auxiliary drive expertise, the EA0168 alternator decoupler pulley is engineered for vehicles that rely on precise belt-drive control and reduced torsional vibration. This part is used in applications where the alternator must decouple under changing engine speeds to help maintain smoother operation across the accessory drive system. This part cross-references 2781500060 and 5350168100 for the same application. Compatible Mercedes-Benz coverage includes 2011-2014 S63 AMG, 2012-2014 C250, 2012-2014 CLS63 AMG, 2012-2014 E63 AMG, 2012-2014 ML63 AMG, 2012-2014 SLK250, 2013-2015 GLK250, and 2013-2014 C300, C350, E350, GLK350, G63 AMG, GL63 AMG, SL63 AMG, and SLS AMG. The INA EA0168 is also listed for 2014 CLS63 AMG S, E63 AMG S, and SLK350, plus 2011-2014 CL63 AMG and 2013-2014 C250, C300, C350, E350, and GLK350 applications.

What It Helps Address

• Alternator pulley noise or rough operation
• Belt vibration in the front accessory drive
• Accessory drive stress from engine speed changes
• Premature wear in FEAD-related components
• Fitment issues when replacing the original Mercedes-Benz decoupler pulley

Installation Notes and Tips

Verify the vehicle’s original part number and engine application before ordering. Confirm fitment against the existing pulley and accessory drive layout on your Mercedes-Benz C250, E350, or GLK250 before installation. Because this is a precision drive component, proper alignment and belt condition should be checked during service.

Quality Assurance

INA supplies FEAD components with a focus on vibration damping and system-level maintenance for modern high-load engines. The EA0168 is cataloged as an alternator decoupler pulley for select Mercedes-Benz applications and is identified by INA part number EA0168.
