Abstract An internal combustion engine is coupled with an unrelated transmission utilizing a connector plate disposed between a powered flywheel related to the engine and a transmission flywheel which is related to the transmission assembly. An annular disc is utilized to connect a housing of the flywheel to a housing of the transmission assembly.

In a drive train within a motor vehicle having an internal combustion engine coupled to an unrelated transmission assembly by a connector plate; said internal combustion engine comprising a powered flywheel having a ring gear attached thereon and a housing to house said powered flywheel; said transmission assembly including a transmission flywheel, a pilot bearing disposed in the center of said transmission flywheel and a pilot shaft engaging said pilot bearing, wherein said transmission flywheel is attached to said transmission assembly through said pilot shaft; a transmission housing related to and housing said transmission assembly; an annular disc disposed between and attaching said engine housing and transmission housing, said annular disc being of a thickness so as to permit said transmission housing to operate in conjunction with said connector plate and said transmission assembly to operate as originally intended; said powered flywheel and said transmission flywheel each having a plurality of circumferentially disposed holes, the holes of said powered flywheel being threaded; said connector plate being generally circular and having first and second sets of circumferentially disposed holes, said first sets of holes being in alignment with the holes of said powered flywheel, said second set of holes being threaded and in alignment with the holes of said transmission flywheel, said connector plate further including a generally circular protrusion on the side thereof facing said powered flywheel for mating with a corresponding opening in said powered flywheel; a first plurality of bolts extending through said first set of holes into threaded engagement with said powered flywheel holes for attaching said connector plate to said powered flywheel; a second plurality of bolts extending through said transmission flywheel holes into threaded engagement with said second set of holes for attaching said connector plate to said transmission flywheel; and said connector plate having a third set of circumferentially spaced holes defining threaded openings therethrough for disengaging said connector plate from said powered flywheel when bolts are tightened through said third set of holes.
