Alternator Replacement Parts  452 Products

The alternator, which is an indispensable part of the engine for charging and power supply, is composed of different parts such as the regulator, the brushes also called carbon because they are made of carbon, the brush holder, the bearings, the diode bridge, the stator, the coils or inductor set, the serpentine pulley or disengageable pulley depending on the model.

There are many brands such as Denso, Hitachi, Bosch, Valéo, Lucas, Magneti marelli, Iskra or Letrika as well as many manufacturer brands.

Our wide range of parts covers these different brands.

It is always very important to have the reference of the alternator to find its components.


  • Rectifier

    The Rectifier
    is also called a rectifier because of its function of rectifying alternating current continuously. A very wide variety of brands are covered by our products.

    To search for parts, provide the reference of your alternator, type it in the site search bar at the top of the home page.

    However, if you do not find the right product, please do not hesitate to contact us at

    We will then do a precise search in order to answer you as well as possible.

  • Brushes / Brush Holder

    The alternator includes brushes also called carbon, which can be changed alone or in combination with the brush holder or regulator.

    The assembly varies according to the brands.

    Our parts are from the cargo brand, Hc-parts, which is a branch of the Bosch group, covers a very wide range of alternators.

    For car alternators, truck alternators, tractor alternators, construction or agricultural machinery alternators.

    It is best to check the condition of the rotor manifold (copper part) during repair. If this part is too damaged, new brushes will not be enough to solve the failure.

    Our range of spare parts for rotor, stator, diode bridge, alternator regulator is new and of high quality.

  • Pulley

    The pulley is a round part fixed on an axis which on an alternator is called a rotor. The pulley allows the belt to be driven.
    The pulley is fixed on the alternator rotor by a nut for conventional pulleys and by a specific set of keys for disengageable pulleys.
    A pulley can have several outlets or grooves depending on the electrical equipment of the vehicle.
    A wide range of quality pulleys is available in this section for many alternator brands such as BOSCH, DENSO, VALEO, MITSUBISHI, HITACHI and others.

    The regulator often referred to as electromechanical was used in the automotive industry with dynamo and/or alternator and is now integrated into the alternator.

    It regulates the loa, it includes brushes that act on the alternator manifold.

    Since the alternator produces alternating current, it must be rectified in direct current through the diode bridge, the regulator then makes it possible to regulate (as its name suggests) according to the need.

    If the alternator is defective, it does not necessarily comes from the controller, it is necessary to test it in order to have a correct diagnosis.

    It is necessary to check the condition of the commutator to ensure that the brushes can be properly set in place and the brushes can sometimes be replaced alone.

The reference is essential to determine the right components because each brand has its own nomenclature to authenticate its alternators.

The reference can be numeric or alphanumeric so it allows via an exploded view to find the right spare parts, regulator, carbon, diode bridge, stator, pulley, rotor or slip ring.

It is important to make a precise diagnosis by putting the alternator on a test bench. The exact name of the manufacturer Denso, Bosch, Valeo, Mitsubishi and others, will then allow you to find the right parts and to repair at best.

Pictures of parts alone are not enough to determine the right model, the electrical characteristics being defined only by the reference.
