The crankshaft pulley provides the drive for the components located on the drive belts. Each belt is automatically pre-loaded by a tensioner and is routed over deflection idler pulleys. The idler pulleys ensure that the belt has maximum contact with the component pulleys in order to maintain sufficient grip between the belt and the component driven pulleys. This ensures a slip-free drive of the accessory components.
