Valeo Rotating Freewheel Pulley Alternator Pulley 599252

Valeo enlarges its Electrical Systems offer with the Freewheel Pulley range. A Freewheel pulley is the mechanical link between the alternator and the engine output crankshaft pulley. The pulley drives the alternator which allows the battery to be recharged. The Overrunning Alternator Pulley (OAP), also called the freewheel pulley, is a spare part of the complete alternator. It is composed of a pulley with an outside diameter suitable for fitting a “poly-V” belt (drive belt), a one-way clutch unit with bearing supports, an inner ring, two seals and an end cover in plastic.
