What It Helps Address

• Belt noise from a worn idler pulley
• Uneven belt tracking in the accessory drive system
• Vibration transfer through the FEAD assembly
• Premature belt wear caused by pulley surface or bearing wear
• Accessory drive service needs on Mercedes-Benz Sprinter 2500 and Sprinter 3500 vans

Installation Notes and Tips

Verify belt routing and pulley alignment before installation. Inspect the accessory drive belt, tensioner, and adjacent pulleys for wear at the same time, since related components often age together in the FEAD system. Confirm fitment by matching the vehicle year and model to the listed applications for FP05661.

Quality Assurance

INA positions this pulley within its FEAD component lineup for high-load engine applications, with emphasis on vibration damping and reliable belt-system operation in limited space.
