Design of a Removal Tool for Air Dryer Filters on Scania P410 Using the 7UP++ Method
Keywords:
Special tools, 7UP method, Air dryer filter, Scania P410Abstract
This study aims to design and evaluate the effectiveness of a specialized tool to facilitate the removal process of the air dryer filter on Scania P410 units, particularly in cases where the locking nut is detached. Common issues such as difficulty in filter removal, risk of thread damage, and potential harm to surrounding components are the main focus of this research. The custom-designed tool provides optimal grip without damaging adjacent parts, thereby improving maintenance efficiency and reducing the risk of component failure. Testing results show that the use of this tool can significantly reduce filter removal time from 30 minutes to just 5 minutes, representing an efficiency improvement of 83.3%. Therefore, the tool is proven to be effective in supporting maintenance processes, enhancing technician safety, and minimizing vehicle downtime. This study recommends the widespread adoption of the specialized tool and technician training to ensure safe and efficient air dryer filter maintenance.References
