Alternator Pulley, OEM - E70 X5 3.0si, E71 X6 35i

OEM replacement alternator pulley for E70 X5 3.0si with a Valeo alternator and 7-rib belt.

This pulley is known as a overdriving, decoupling, OAD, or ADP pulley and has an internal dampening system that can wear out or fail. This can cause improper belt tension, vibration, slipping, noise, and poor alternator performance. There is no suggested replacement interval so check the overall condition of the pulley and listen for buzzing or squealing noises from the pulley itself. Removal and installation requires a special tool - see Related Items below.

This is an OEM alternator pulley manufactured by INA - the original supplier to BMW for this part, as well as many other pulleys and bearings. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
