Scania tests out ‘good as new’ remanufactured gearbox

The remanufactured gearbox was subject to exactly the same rigorous steps and inline quality and function tests as gearboxes that are made from entirely new parts.

It was assessed on the same test rig used for new ones, with monitoring of 100 quality and function parameters. The gearbox met all those requirements and so could be confirmed as being ‘as good as new’, which ensures that it meets the quality and performance standards for being installed on Scania vehicles. As well as the remanufactured gearbox being as good as new, the actual production process showed substantial environmental advantages.

While replacement rates during gearbox remanufacturing can vary between roughly 10% to 100% depending on wear-and-tear history, this particular gearbox consumed approximately 50% less material and caused 45% fewer carbon emissions compared with gearboxes made only with new components.

“What an achievement by the project and everyone involved,” said Fredrik Nilzén, head of sustainability at Scania. “This remanufactured gearbox is a compelling example of how the manufacturing of heavy vehicles can become more sustainable, circular and efficient, while still retaining the highest quality standards.”

Remanufacturing, which sees the reuse of old parts to create new products with as-good-as-new quality, is viewed by the automotive industry as a promising strategy for achieving climate goals and supporting the transition towards a circular economy. It also addresses increasing resource scarcity issues.

It is hoped that the iReGear project, which this piece of research was part of, will help lead the way for the industry to make this shift in the efforts to create a more sustainable and cleaner transport industry.
