OEM replacement alternator pulley for E82 128i (N51 SULEV model), E9X 325i/330i, E9X 328i (2007-2008 N51 SULEV model), and E60 525i/530i N52. This pulley fits cars with a Valeo alternator.

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 part number replaces or is an alternative to BMW part numbers 12 31 7 570 152, 12317550001, 12317536960, 12317516105, 12317505927.
