Abstract
A clutch assembly for transmitting power from an output shaft of an engine to an input shaft of a gearbox includes annular friction surfaces on at least one of the flywheel and the pressure plate. The annular friction surface has a plurality of grooves that extend across the annular friction surface away from an inner rim of the friction surface toward an outer rim of the friction surface to prevent a reduction in friction caused by outgassing or abraded particles trapped between engaging friction surfaces.
