Development of V-Twin Motorcycle Valve Stem Seal Non-invasive Removal Tool

Vehicle maintenance over the last few years has become more expensive due to the COVID related crisis, spare parts transportation problems, and latest price rises - related to war over Ukraine. There is also evident rise in fuel and lubricant prices, which is related to crude oil price rises. So, due to this reasons, older types of motorcycles and automobiles are often serviced in small repair shops, or maintenance is done by owners instead of certified dealer shops. This paper deals with tool construction designed for changing valve stem seals in V-twin motorcycle, with special emphasis on non-invasive procedure. With this tool, there is no need for head removal (as it is done in conventional procedure), thus leading to lower maintenance costs. Top-end gaskets sets are expensive, and work related to heads removal of V-twin motorcycle engine is time consuming. For the design of this oil seal removal tool, a reverse engineering technology is used, such as CAD (computer aided design, CAM (computer aided machining) and FEM (finite element analysis).
