A used genuine OEM Mercedes Drive Belt Idler Pulley Mount / Bracket, part number 2782361440. This bracket secures the idler pulley on the serpentine belt system. When the mount fails, the pulley can wobble, leading to belt squeal, misalignment, or premature belt wear. It fits the 4.7L and 5.5L turbocharged V8 engines found in the S550 and S63 AMG.
