Alternator for Mercedes-Benz Bosch Applications
This WAI alternator is built for classic Mercedes-Benz charging systems that require a Bosch-style 55 amp unit. Part number 13056N is a 100% new alternator, not remanufactured, with the output needed to support the electrical load of the vehicle.
Key Features
- 55 amp amperage rating for steady charging performance
- 100% new construction, not remanufactured
- Internal regulator for integrated voltage control
- External fan design for cooling support
- Clockwise rotation with a single-groove V-belt pulley
- Pulley included for a more complete replacement setup
Detailed Description
WAI part number 13056N is an alternator engineered for Mercedes-Benz models equipped with Bosch 55 amp charging systems. It uses proprietary components and manufacturing processes to support long service life and consistent performance. The Bosch family design, internal regulator, and clockwise rotation make it a direct match for many vintage Mercedes-Benz 300D, 240D, and 450-series applications.
This alternator is a practical choice for restoring charging output on older Mercedes-Benz vehicles where stable electrical supply is critical for ignition, lighting, and accessory operation. The included pulley and V-belt configuration align with the original system layout for the listed applications. This part cross-references Bosch (e.g., 13056, 0 120 489 061) for the same application.
What It Is Used For
- Low charging output from a worn alternator
- Battery warning light caused by charging system failure
- Inconsistent voltage delivery to vehicle electrical components
- Noise or wear related to alternator bearing or internal component failure
- Replacement of a Bosch-style alternator on classic Mercedes-Benz models
Installation Notes and Tips
Verify the Bosch family match, 55 amp rating, clockwise rotation, and V-belt pulley configuration before installation. Confirm the vehicle’s charging system layout against the listed fitment, including the standard applications noted for Mercedes-Benz 300CD, 300D, 300SD, 300TD, 240D, 280CE, 280E, 280SE, 450SEL, 450SL, 450SLC, 230, 280, 280C, 280S, and 450SE. The fitment notes also indicate noise suppressor inclusion on the listed applications.
Quality Assurance
WAI states that this alternator is engineered to deliver the amperage required by modern vehicle electrical demands and is manufactured as a new unit using proprietary components and processes for durability and performance.
