INA EA0361 Overrunning Alternator Decoupler Pulley OEM Replacement

The INA EA0361 is an overrunning alternator pulley (OAP) designed as a direct OEM replacement for worn or failed alternator decoupler pulleys. This precision-engineered component connects the serpentine belt drive system to the alternator, allowing the alternator shaft to overrun the belt when engine speed drops suddenly — reducing vibration, belt wear, and stress on the charging system.

Key Features:

• Direct OEM replacement design for precise fit and function
• Overrunning (decoupler) clutch mechanism reduces drivebelt and alternator bearing load
• Precision-engineered by INA (Schaeffler Group), a global leader in engine and belt drive components
• Constructed with quality materials to meet or exceed original equipment standards
• Serpentine/poly-groove belt compatible design
• Helps eliminate accessory belt noise, vibration, and harshness (NVH)

INA is a trusted Schaeffler brand supplying OEM-quality front end accessory drive (FEAD) components to major vehicle manufacturers worldwide. The EA0361 alternator pulley restores proper charging system operation and extends the service life of related belt drive components.
