The BMW 518 stock clutch disc and pressure plate by Valeo are designed with a disc diameter of 215 millimeters and a thickness of 7.5 millimeters to provide high mechanical strength and precise torque transfer. The assembly is made from alloy steel with a tensile strength of 900 megapascals, ensuring stable performance at operating temperatures up to 270 degrees Celsius. The disc surface is reinforced with an anti-wear coating and a hardness of 42 to 46 Rockwell C, preventing corrosion and deformation under continuous pressure. The clutch plate features six diaphragm springs and a friction coefficient of 0.34, enabling smooth and slip-free power transfer.
This Valeo clutch kit for the BMW 518 can withstand up to 200 newton meters of torque and is optimized for a 1.8-liter 16-valve engine. The net weight of the assembly is 6.1 kilograms, ensuring dynamic balance and reduced vibration. The multilayer friction plate reinforced with fibers provides a service life of over 80,000 kilometers. The internal damper system with an 18-degree torsion angle prevents sudden shocks from reaching the gearbox and improves power transmission efficiency.
