Power Steering Pump Pulley, BMW - E39 M5

This part is listed by BMW as BMW part number 32427830838 (32 42 7 830 838) and is described as the pulley for the power steering pump on E39 M5. Pulleys experience wear and stress cracks and can lead to a total failure of the pulley itself. Weak points are not usually in the ribs for the belt but in the mounting holes to the pump. If you remove the belt for maintenance work you should consider replacing the pulley too.

This is a Genuine BMW M5 S62 PS pump pulley with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
