Genuine Mercedes Benz C63 AMG Sheave Pulley

The Sheave Pulley works in conjunction with the tensioner pulley/tensioner assembly to maintain tension on the belt as well as guide the belt. Sheave Pulley are also used to achieve ideal belt routing around the engine drive accessories such as the power steering pump, water pump, A/C compressor, and alternator.

The Sheave Pulley is an often overlooked maintenance item but it is just as important as the belt tensioner itself. In most cases it is recommended to replace the sheave pulley at the same time as the belt tensioner.
