Abstract
An improvement in a motor vehicle transmission/casing assembly where an end pressure plate of a clutch plate assembly, is positioned on a surface of an hydraulic piston located in the casing of the transmission/casing assembly. Spaced externally extending splines on the pressure plate are positioned in correspondingly spaced channels in the interior casing wall, for arresting the pressure plate from rotation. A loosely fitted buffer member or liner is positioned in each channel between the periphery of the externally extending splines and the walls of the channel for intercepting contact between the spline of the pressure plate and the wall of the channel. A groove in a circumference of the interior wall of the casing, supports a snap ring which transverses each channel and blocks the buffer member, positioned in the channel, from slipping out of the channel. The contact intercepted by the buffer member is absorbed by the mass of the buffer member and transmitted to the walls of the channel over a substantially larger contact area than that of the contact between the buffer member and the spline, thus preventing damage to the casing wall.
