What is the price of a used Caterpillar alternator?

The price of a used alternator varies depending on the machine model, voltage (12V or 24V), and current rating. Choosing second-hand for a CAT 315 excavator or a compact loader allows significant savings compared to new parts, reducing your maintenance costs.

For powerful engines like the C18 or the 3208, the price reflects the power and rarity of the part while remaining very advantageous. Controlled origin and reliability verified by our technicians ensure excellent value for money, a key factor for the profitability of your projects.

To get the exact price of your CAT reference, contact Codimatra experts with your serial number. They will offer the fairest price based on your machine's technical configuration and immediate stock availability.

Several signs indicate a defective alternator on a Caterpillar machine. The first clue is a battery that discharges quickly, even after a full charge. You might also notice dashboard warning lights turning on abnormally, electrical components malfunctioning, or difficulties starting the machine. A multimeter test on the alternator output voltage confirms the diagnosis.

Codimatra covers a wide range of Caterpillar machines, from hydraulic excavators on tracks and wheels to wheel loaders, bulldozers, compactors, and motor graders. The used alternators available are compatible with many series, such as 315, 318, 320, 325, as well as 950 and 966. To verify compatibility with your specific model, simply contact Codimatra with your machine's reference.

The alternator's voltage directly depends on the machine's electrical system. Smaller CAT machines, like mini excavators or compact loaders, typically operate on 12V systems. Larger machines, such as big hydraulic excavators or bulldozers, use 24V systems to meet higher electrical demands. Installing an alternator with the wrong voltage would damage the battery and electrical equipment.

At Codimatra, every used Caterpillar alternator is carefully inspected before sale. The condition of the part is checked to ensure it functions according to professional standards. Alternators come from machines dismantled under controlled conditions, ensuring serious traceability. For any questions about a specific part's condition, the Codimatra team is available to provide detailed information prior to purchase.

The most reliable method is to note the original part number directly on the installed alternator, usually engraved or printed on a label stuck to the housing. Alternatively, the machine's serial number, visible on the manufacturer’s plate, allows identification of the exact part in CAT’s technical documentation. You can provide this information to the Codimatra team, who will find the corresponding used alternator.

To place an order, visit codimatra.com and browse the used alternator catalog, or contact the team directly by phone or via the online form. Have the part reference or your machine’s serial number ready to facilitate the search. Once the part is identified and approved, the order is processed promptly with shipment across France.
