Abstract
A cover assembly for a friction clutch for a motor vehicle includes a cover and a ferrule. The cover has a ferrule aperture passing therethrough from an outer side to a inner side. The ferrule is a one piece unitary structure and is disposed in the ferule aperture. The ferrule has a spring receiving portion and a base portion and axis of orientation passing through both the spring receiving portion and the base portion. The spring receiving portion projects from the ferrule aperture beyond the inner side. The spring receiving portion has a spring aperture. The base portion has a pilot portion disposed within the ferrule aperture. The pilot portion is of a size complementary to the ferrule aperture. The size of the pilot portion is selected to enable the ferrule to be positively positioned within the ferrule aperture. The base portion also has a travel limit portion extending radially beyond the ferrule aperture and engaging the outer side of the cover to prevent the base portion from passing through the cover.
