The heavy-duty automotive sector has a major impact on the Brazilian economic scenario, representing 20% of the industrial GDP in 2021, and it’s projected to increase by 8.2% in 2022, in addition to a positive long-term perspective due to aging of the truck fleet in the country. To keep up with the sales volume, the manufacturing sector faces challenges to meet customer demand. The present work aimed to apply lean manufacturing tools to adapt a production cell to the takt time of the main line, following A3 methodologic, with the definition of the current state of the assembly, checking muri, mura and muda, and acting mainly in the waste analysis. Subsequently, improvement actions were applied, such as simulation with AutoCAD, and after a layout change, resulting in a gain in productivity, which showed a decrease of 41.6% in the process time in one of the products, in addition to eliminating negative ergonomics and safety points raised during the analysis. With this methodology, it was possible to achieve the main objective, which consisted in eliminating the risk of line stoppages due to lack of components and adapt the process time of the pre-assembly cell to the takt time of the main production line.
