Used Construction Alternators: Compatible Parts for All Brands

Our stock of alternators for construction machinery

Our 7000 m² facility houses a wide selection of spare alternators taken from machines destined for dismantling. Each unit is carefully identified by its voltage (12V or 24V) and amperage (ranging from 40A to over 100A for larger models). We cover all needs for used construction equipment, from compact mini-excavators to heavy articulated dump trucks.

Our specialized technicians carry out meticulous disassembly of each alternator. Before stocking, these components undergo thorough electrical testing on a test bench to verify charging voltage stability and bearing condition. This technical expertise allows us to offer ready-to-use products for a quick return to service on your sites.

What is the price of a used alternator?

Is it a smart choice to buy a used alternator? Absolutely, as it allows substantial savings, typically between 30% and 50% compared to the price of a new manufacturer part. The price of a replacement alternator mainly depends on output power, machine brand, and reference rarity. For example, a standard model for a wheel loader will be more affordable than a specific unit for a mining machine.

The price also reflects the level of inspection carried out in our workshops. Buying from Codimatra guarantees you a part whose functional potential has been verified, avoiding the risks often encountered with private offers.

How to choose your replacement alternator?

To ensure perfect integration with your combustion engine, several technical criteria must be checked. The lifespan of your electrical system directly depends on this choice:

• Voltage (V): Most light construction equipment operates on 12V, while heavy machinery requires 24V (providing about 28V under load).
• Current (A): It must match your equipment’s requirements (lighting, air conditioning, onboard systems). Too low a current will not properly charge the battery.
• Mounting and pulley type: Check the number of grooves on the pulley and alignment to ensure correct belt tension.
• OEM reference: This is the most reliable indicator. It is generally printed on the manufacturer’s original label (Bosch, Denso, Mitsubishi, etc.).

Compatibility with leading machinery brands

Thanks to our database of over 40,000 cross-referenced parts, we ensure full compatibility with market leaders. Whether you operate #FAMILLE# excavators from Caterpillar, Komatsu loaders, or JCB backhoe loaders, we have the right replacement part. Our expertise also extends to brands like Volvo, Liebherr, Case, or Doosan.

The standardization of electrical components often facilitates interoperability. For instance, an alternator originally fitted on a Cummins engine can perfectly suit different models of wheel loaders from various brands. Our technical advisors are available to confirm these matches and secure your purchase. Consult our experts to validate compatibility with your machine’s serial number.
