BBB Industries 11220 Alternator

Reman Alternator for Mercedes-Benz Applications

BBB Industries REMAN ALTERNATOR 11220 is a 12-volt, 180-amp replacement alternator built for select Mercedes-Benz charging systems that use a Bosch unit. It features an internal voltage regulator, air cooling, and a conventional pulley with a 6-groove serpentine belt setup.

Use this remanufactured alternator when you need a direct replacement for Mercedes-Benz E350, E550, S550, GL550, ML350, and related models that call for the 180-amp Bosch-style configuration. Part number 11220 is also a fitment match for several OE cross-reference applications.

• 180-amp amperage rating for factory-style charging output
• 12V electrical system with internal voltage regulator
• Bosch OE manufacturer reference for select Mercedes-Benz applications
• Air-cooled design with internal fan
• Conventional pulley included, 6-groove serpentine belt type
• Clockwise rotation and negative polarity
• Plug clock position: 7
• Outside pulley diameter: 1-7/8 in. (48 mm)

Product Details

BBB Industries REMAN ALTERNATOR 11220 is built for vehicles that require a Bosch-style alternator with a 180-amp output and internal regulation. The remanufactured design restores charging-system function for Mercedes-Benz models such as the 2006-2011 E350, 2007-2011 E550, 2007-2010 CL550, 2008-2010 GL550, and 2008-2010 ML350. It also covers additional applications including G550, R350, S550, SL550, CLK550, C300, and SLK350 where the listed Bosch unit is specified.

This part cross-references Bosch 0-121-715-006 and 0-121-715-014 for the same application. Part number 11220 is a practical OE-style replacement when the original alternator no longer maintains proper system voltage.

What This Alternator Helps Address

• Battery warning lights caused by charging-system failure
• Low system voltage during driving or idle conditions
• Dim lights and electrical accessories operating inconsistently
• Hard starting related to insufficient alternator output
• Charging noise or alternator wear in Bosch-equipped Mercedes-Benz vehicles

Installation Notes and Tips

Verify pulley style, plug clock position, amperage rating, and OE manufacturer reference before installation. This alternator uses a 6-groove serpentine pulley, clockwise rotation, and a 7 o'clock plug position. Confirm vehicle-specific fitment for your exact Mercedes-Benz year, model, and charging-system configuration, especially on applications noted as optional or excluding high-capacity equipment.

Quality Assurance

BBB Industries remanufactured electrical components are rebuilt to restore proper function in OE-style applications. This alternator is remanufactured for direct replacement use in confirmed Mercedes-Benz fitments listed above.
