INA 5350166100 Alternator Decoupler Pulley

The INA 5350166100 is a precision-engineered alternator decoupler pulley designed to improve belt drive system performance and extend component life. This freewheel-type pulley incorporates a one-way clutch mechanism that allows the alternator to gradually coast down when engine RPMs drop, reducing shock loads on the serpentine belt and minimizing noise and vibration.

Key Features:

• Freewheel clutch design decouples alternator mass during engine deceleration
• Reduces belt tension fluctuations and extends belt service life
• Minimizes noise from alternator operation, especially during rapid RPM changes
• Precision bearings ensure smooth, reliable operation
• OE-quality construction from INA, a division of Schaeffler Group
• Direct replacement for worn or failed alternator pulleys

INA has been a trusted supplier of OE components to major automotive manufacturers for over 70 years. This alternator decoupler pulley is manufactured to strict OE specifications for precise fit and long-lasting performance. Installation may require special tools depending on the vehicle application.
