Product Details
This is a Genuine BMW Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).
This pulley shares its mounting bolt with the alternator, and is used for the main drive belt on the M50-family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines), and also used on the S85 V10. This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time.
This item is 80mm Diameter. Please check the diameter before ordering.
