A frictional clutch for a motor vehicle includes a cover, a pressure plate, a biasing member, an adjustment mechanism and a dust shield assembly. The cover has an axis of rotation. The pressure plate is coupled to the cover for rotation therewith about the axis. The pressure plate has a frictional engagement surface substantially normal to the axis. The biasing member is interposed between the cover the pressure plate, and biases the pressure plate toward an engaged pressure plate position. The adjustment mechanism is centered about the axis and is located at a first radial distance from the axis. The adjustment mechanism is operably disposed between the biasing member and one of the pressure plate and the cover. The dust shield assembly includes an annular wall disposed radially within the adjustment mechanism. The annular dust shield assembly is in axial alignment with the adjustment mechanism. The dust shield assembly is sized and oriented to protect the adjustment mechanism from debris radiating outward from a central area of the clutch.The dust shield assembly is provided with a plurality of retaining clips which extend radially inwardly for attachment of the shield to the clutch cover.
