Used Turbochargers

How a Diesel Turbocharger Works: The Agricultural Engine's Turbo

The turbocharger recovers energy from exhaust gases to drive a turbine. This turbine spins a compressor wheel on the same shaft, which forces more air into the engine cylinders. With increased air volume, the injection system can burn more diesel fuel, boosting engine power and torque without increasing displacement. On a tractor, the turbo works at full load for extended periods—during plowing and transport—placing significant stress on its bearings and lubrication system. Proper operation and longevity therefore depend on regular maintenance: quality oil, clean air filter, and airtight intake system.

Used Turbochargers Available at TMC Bejenne

• Tractor turbos for medium to high power engines, with fixed or variable geometry depending on the model.
• Turbochargers for combine harvesters and forage harvesters, suited for large displacement engines.
• Telehandler and loader turbos, subject to availability.
• Original manufacturer turbos such as Garrett, Holset, or BorgWarner, depending on engine type.
• Related parts: manifolds, air hoses, intercoolers, and intake system components.

Used Diesel Turbochargers by Brand: Renault, John Deere, or Case IH

A tractor’s turbocharger primarily depends on the engine model. John Deere tractors use PowerTech engines, while many Case IH and New Holland machines run on FPT engines. Recent Massey Ferguson, Valtra, and Fendt models often feature AGCO Power or Deutz engines depending on the series. Renault and Claas tractors have also been equipped with John Deere engines across various generations, making some turbos interchangeable between brands. For example, a turbo for a Renault Ares is primarily identified by the engine reference.

Signs and Symptoms of a Failing Turbocharger

• Loss of power under load, especially uphill or during soil work.
• Blue or black exhaust smoke, indicating burned oil or insufficient air supply.
• High-pitched whistle or rubbing noise that changes with engine speed.
• Oil leaks on intake or exhaust sides, visible on hoses and manifolds.
• Unusual fuel or oil consumption without other identifiable cause.
• Radial or axial play on the turbine shaft, observable during visual inspection.
• If these symptoms appear, always check the turbo’s lubrication side before replacement.

Remanufactured, Exchange, or Used Turbocharger?

A used turbocharger comes from a dismantled engine: it is inspected and sold as-is at the lowest price point. A remanufactured or exchange turbo is professionally disassembled, worn parts replaced, and traded in exchange for your old turbo. Turbo repair is possible on some models provided the housing and shaft are intact. For tractors with a few thousand hours, an original used turbocharger often offers the best value for controlled maintenance costs. The exchange option is more suitable for heavily used, newer machines when no used original part is available.

Steps to Buying a Used Turbocharger

Purchasing a turbo requires preparation: key is identifying the exact reference for a perfect fit with your engine.

• Note the brand, model, and serial number of your tractor.
• Record the turbo or OEM reference number engraved on its plate or housing, along with the engine type.
• Check the condition of the offered turbo: no shaft play, no blade damage, no oil traces.
• Identify the cause of failure of your current turbo before replacing it, to avoid repeating issues and shorten turbo life.
• Plan to replace oil, oil filter, and air filter when installing a turbo.

Turbo Replacement Cost

The price of a used turbocharger, like any engine replacement part, depends on the reference, engine type, and condition. Additional costs include labor—especially if removal requires hood or manifold disassembly—gaskets, and fresh oil. A checked used turbo significantly reduces the total expense compared to new parts and avoids manufacturer lead times.
