Product Information

This pulley is primarily specified for BMW applications under OE numbers 11287549557 and 11281440237. It can also serve as a secondary solution for S85 engines by replacing BMW part numbers 11287839133 and 11287839135 when only the pulley is needed (without the lever). In this case, the bolt and backplate must be removed before installation.

This idler pulley does not include a bearing protection cap. We recommend installing a new cap when replacing the pulley, as the old one often breaks upon removal.

Compatible cap (S85 application): 11281730349.

Accessory Drive Belt Idler Pulley
The drive belt idler pulley works with the tensioner pulley and assembly to maintain belt tension and guide proper routing around engine-driven accessories such as the power steering pump, water pump, A/C compressor, and alternator. It is often overlooked but should be replaced along with the belt tensioner to ensure long-term reliability.

Common Failure Symptoms:
- Visible wear or grooves on the pulley
- Belt squealing
- Chirping or grinding noises from the pulley bearing
- Uneven or abnormal belt wear
- Misalignment of the pulley relative to the mounting surface
