Made By Elcon.  The drive train consists of five parts as shown in the 3D image displayed below.  All parts are shown in a different colors.  The green part is the motor plate and bolts onto the engine.  This then bolts to the large central plate which is shown in blue.  The red part holds the bearing/clutch bell.  The yellow part holds the bearings/lay shaft.  The metal color strip mounts the complete assembly onto the chassis.  The drive train is supplied pre-assembled.
