A remanufactured AGCO Power engine is often the smartest choice when the engine of an older tractor needs a full overhaul. A remanufactured diesel engine extends machine life and reduces environmental impact. For tractor owners and their local service partners, a remanufactured engine means a smooth, predictable job with schedule and costs known up front.
At AGCO Power’s Linnavuori plant in Finland, an OEM factory-remanufactured engine is as good as—often even better than—the original unit as built, because it includes model-specific updates introduced after the original production date.
During remanufacturing, the engine is disassembled and cleaned; all wear parts are replaced and the remaining components are inspected. Parts that pass inspection are reused; faulty parts are replaced. Typically, about 80% of the engine’s mass can be reused. Factory-remanufactured engines carry the same warranty as new.
From the owner’s perspective, the process is easy. Your local service center books a slot for the engine swap. On the agreed date, a remanufactured engine is waiting and is installed in just a few days. The tractor’s old, worn engine is then shipped to the factory to be remanufactured for another customer. Compared to buying new, the owner typically saves around 30% in cost. Time is saved as well versus opening the old engine in the workshop, hunting down the fault, ordering parts, and rebuilding on site.
There is one exception related to emissions regulations: when an engine’s type-approval has expired for more than 20 years, the same factory-remanufactured engine must be used. For this reason, engines with Tier/Stage 0 and 1 emission levels cannot be replaced with a different unit; instead, the engine removed from the tractor is sent to Linnavuori for remanufacturing and reinstalled in the same machine. Newer engines are typically factory-remanufactured in no more than five working days, and even older models in under three weeks.
All factory-remanufactured engines are test-run at AGCO Power’s Linnavuori plant. Upon delivery, the engines meet the technical and visual standards of a new engine. In the photo, engine assembler Juha Kuusinen is test-running a remanufactured engine.
A vast engine portfolio, rapid service
Linnavuori has offered factory-remanufactured engines—and remanufactured fuel-injection equipment, injectors, turbochargers and other components—for over half a century, with fully systematic operations since the 1990s. There are 5,700 different engine variants across the Valmet Diesel, Sisu Diesel, AGCO Sisu Power and AGCO Power names. For the vast majority of these, a factory-remanufactured replacement engine is still available.
“We can remanufacture several engine models dating back to the 1950s and 1960s. For example, we even have brand-new water pumps on the shelf for the 309D engines from that era. We can’t promise to deliver absolutely every engine we’ve ever built as factory-remanufactured, but we can support the great majority,” says Jussi Rinne, Director, Quality & Aftermarket at AGCO Power.
Engines made in Linnavuori power machines from Valtra, Massey Ferguson, Fendt and Challenger tractors to a wide variety of combine harvesters from Dronningborg to Sampo, as well as trains, ships, port cranes, armored vehicles, forestry machines, generators and countless other applications. While the main components are common, every engine variant has its own specifics.
Major investment expands capacity
In autumn 2025, AGCO Power announced €54 million of investments at the Linnavuori engine plant, with a portion directed to the Reman operation. These investments double the remanufacturing floor space and increase annual capacity from about 1,000 to roughly 2,500 engines.
Demand is expected to grow: around 10% of engines typically come back for factory remanufacturing after 10–20 years of service, and overall engine production volumes have climbed strongly since the early 1990s.
“We can now run the entire remanufacturing process within dedicated AGCO Power Reman facilities. Previously, remanufactured engines had to be moved to other halls for painting, test running and dispatch. As demand grows, we’re also recruiting more people into Reman. One technician still builds each engine independently from start to finish. Typically, colleagues join us from new-engine production once they’ve built up solid experience,” Rinne adds.
