Detailed Description
BBB Industries part number 11739 is a reman alternator engineered around the OE-style configuration used in select Mercedes-Benz charging systems. The unit uses a 6-groove serpentine pulley, internal fan cooling, and a 12 o'clock plug clock position to match the specified electrical layout. With a 250-amp rating and internal regulator, it is suited to vehicles that require stable charging output under heavier accessory loads.
This alternator fits 2014-2017 Mercedes-Benz S550 and 2017 Mercedes-Benz Maybach S550, N/A. The OE manufacturer reference is Valeo, and the part number 11739 helps confirm the correct charging-system match when comparing replacement options.
What It Helps Solve
- Low charging output from a worn alternator
- Battery warning lights caused by charging-system failure
- Voltage instability from a failing internal regulator
- Belt-drive noise related to alternator pulley wear
- Electrical strain in high-demand charging applications
Installation Notes and Tips
Verify pulley groove count, plug clock position, rotation direction, and amperage rating before installation. Confirm the vehicle uses a serpentine belt drive and compare the OE reference and part number 11739 against the original unit before replacement.
Quality Assurance
BBB Industries remanufactured components are built to meet application-specific replacement requirements. This alternator is referenced to OE manufacturer Valeo for the listed fitment.
