The purpose of this article is emphasize how a suitable Manufacturing can influence and guarantee the functionality of Clutch System – Clutch Cover, Clutch Disc and some components from hydraulic System, for example, Concentric Slave Cylinder - CSC. The most people or most of customers in our Market does not know what we have behind of Clutch Pedal. The major function of Clutch System would be an interruptible coupling between the engine and manual transmission, in simple terms the idea would be provide torque, torque interruption, provide comfort during the launch of vehicle and also attenuate the combustion engine s irregularities. In the meantime, behind of this concept, function of the product, there is an import manufacturing operation that if not carry out accordingly among the O&M companies, can jeopardize the product, reduce lifetime and consequently to have issues in the field (customer satisfaction). In parallel, we would like to share all Lesson Learned that we got thru the years with new Engineers and offer to the market the Best Practice in terms of Manufacturing for Clutch  System.
