Idler Pulley

Although idler pulleys dont directly spin an accessory, their function in the engine bay is no less vital. When these wear they begin to squeak and squeal which can range from annoying to deafening. Turner Motorsport carries replacement idler pulleys that will eliminate the noise and keep your belts turning smoothly.

This is an OEM Febi 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).

If your accessory belt idler pulley shows signs of excessive wear—such as wobbling, grinding, or squealing from a failing bearing—it should be replaced before it leads to belt failure. When replacing your idler pulley, it's a good time to inspect other belt drive components like the tensioner and belt for wear. Turner Motorsports offers a full selection of belts, tensioners, pulleys, and related hardware to keep your BMW’s belt drive system running smoothly.
