ABSTRACT:
A heat puck has a trapezoidal shape with a steel base plate and a thick layer of a high heat capacity material such as copper. The heat puck is attached to either or both the pressure plate and flywheel of an otherwise conventional automotive clutch assembly. Preferably a circular array of heat pucks are mounted on a respective plate or flywheel. The puck is mounted with a large diameter shoulder member that extends through an aperture in the puck and is received in an aligned receptacle in the surface of the plate or flywheel. A screw or rivet fastener extends through the shoulder member, puck and plate or flywheel to retain the assembly. The shoulder member provides the necessary torque resistance to the assembly, protection the fastener from stress failure.
