This clutch disc assembly transmits torque from the engine to the gearbox input shaft. It sits between the flywheel and the pressure plate, engaging and disengaging drive to the transmission. Wear on the friction facings reduces clamping force, leading to slippage under load and incomplete power transfer. As an original-manufacturer component, its friction material and spline geometry match the original assembly's engagement characteristics, so no adjustment of the release mechanism is needed. On installation, ensure the disc is centered with a pilot tool before torquing the pressure plate bolts to specification.
