What are the benefits of a Mercedes-Benz Genuine Remanufactured alternator?

An electric alternator as a genuine remanufactured part from Mercedes-Benz meets exacting quality requirements and standards at all times, comparable to those applicable to the new part. In our remanufacturing process, all component parts are disassembled and professionally cleaned. The threads are repaired and wear parts generally replaced with new parts. The balanced rotor provides for smooth running and excellent durability. Finally, the electric alternator is protected against corrosion using special varnishes and tested by specially trained Mercedes-Benz professionals on one of our test stands.

How does an alternator work?

Three-phase alternators are used to convert mechanical kinetic energy into electrical power. In vehicle applications, these are referred to simply as alternators. In generating power, the engine drives the truck's belt drive, providing mechanical energy that the alternator converts. Energy conversion efficiency means that the conversion process consumes more energy than is produced.

How do you identify a defective alternator?

Because the alternator is subject to more friction on the bearings, collectors and slip rings, these are the component parts that suffer the most wear.

A defect in one of these component parts may have the following consequences:

  • The battery is not charged while the engine is running
  • The battery indicator lamp flickers and the V-belt makes a squealing noise
  • The battery indicator lamp gets brighter as the engine speed increases
  • Unusual noises from the belt drive
  • The positive diode is defective, and the battery discharges while the vehicle is stopped
  • The battery does not charge, and the battery indicator lamp is lit up

Mercedes-Benz quality with a genuine remanufactured truck alternator.

Quality and reliability are paramount when it comes to Mercedes-Benz Genuine Remanufactured alternators. Remanufacturing of an alternator incorporates expertise in the latest series production methods from Mercedes-Benz. That ensures a high level of quality – so much so that a remanufactured part is comparable to the equivalent new part. Not only that, but using resources smartly and economically also means that you reduce the burden on both your budget and the environment.
