Used Reducers: Wide Selection of Parts for Construction Equipment

Used Gearmotors and Electric Gearmotors

A gearmotor is a compact assembly that combines a motor and a reducer in a single housing. On construction equipment, hydraulic gearmotors are the most common configuration: found in turret rotation systems, winches, and certain auxiliary functions. The used swing reducer is among the most requested references in this category, covering tracked and wheeled excavators from all brands.

The used electric gearmotor is more commonly found on auxiliary equipment: actuation systems on aerial platforms, hybrid excavators, or lifting and handling equipment associated with construction machines. If your application involves an electric motor and reducer assembly, please provide the technical specifications — power, reduction ratio, manufacturer references — so our technical team can perform a tailored search in our inventory.

Used Mechanical Speed Reducers

Mechanical speed reducers decrease the rotational speed delivered by the combustion engine to increase the torque available at the working components. On construction machines with hydrostatic transmissions — wheeled loaders, dump trucks, backhoe loaders — they are integrated within the drivetrain between the engine and axles. This type of reducer is often paired with used gearboxes and transfer case systems for machines with hybrid transmissions.

Codimatra regularly stocks used mechanical speed reducers sourced from end-of-life machinery or damaged equipment. Each part is inspected and tested in our workshop before being added to stock: gear condition checks, bearing verification, and sealing tests of housing gaskets.

Used Planetary Reducers, Mini-Excavator Reducers, and Baudouin Reducers

The planetary (or epicyclic) reducer technology is the most widely used in compact equipment. Its satellite gear design offers high reduction ratios in a minimal space: it is integrated into translation gearmotors for mini-excavators and into used wheel reducers for axle-mounted machines. This component undergoes significant stress and is regularly sought after among spare parts in the construction equipment market.

The used mini-excavator reducer refers to all reducers installed on compact machines: translation reducers, turret rotation reducers, and planetary wheel reducers depending on the equipment type. Please specify the exact model of your mini-excavator as well as the function concerned — translation or rotation — to enable our team to quickly identify the part in stock.

The used Baudouin reducer pertains to equipment powered by a Baudouin propulsion unit: certain lifting machinery, site pumps, or propulsion systems use Baudouin blocks paired with specific reducers. If you have the manufacturer reference, our team can conduct a search through our partner dismantling network.

Caterpillar, Liebherr, Komatsu, Volvo, and Case: Used Reducers for All Brands

Our inventory of used reducers covers the main brands present in the French construction fleet, with strong representation of widely distributed brands in France.

Caterpillar is the most represented brand in our reducer stock, including wheel reducers for wheeled excavators, loaders, and bulldozers from the Cat range. Liebherr is among the top represented brands for wheel and swing reducers, with equipment known for the robustness of their transmission systems. Komatsu is regularly in stock, with reducers suitable for PC series excavators and WA loaders. Volvo, with its widely popular series of wheeled excavators and loaders in France, is also represented. Case completes the offer, notably for translation and swing reducers for construction excavators.

If your brand or exact model is not listed here, please provide us with your reducer's manufacturer reference: our technical service will perform a search in our inventory and our partner dismantling network.

Cost of a Used Reducer at Codimatra

The price of a used reducer varies depending on the part type — wheel, swing, or planetary reducer — brand, machine tonnage, and the general condition of the part. A wheel reducer for a high-capacity loader typically costs significantly more than a planetary reducer for a compact mini-excavator. The condition of the gear teeth, the presence of abnormal bearing play, and the state of housing seals are the main factors influencing the value of a used reducer.

At Codimatra, prices are provided upon request based on parts available in stock at the time of your inquiry. Contact our technical service specifying the manufacturer reference, brand, and model of your machine to receive a tailored offer.
