Abstract
A symmetrical splined drive shaft interconnects a specially configured socketed flywheel with the drive train of a vehicle. The socketed flywheel is formed to receive a retaining ring so that when a portion of the flywheel housing and the drive train are separated from the remaining portion of the flywheel housing encompassing the flywheel the symmetrical splined drive shaft disposed in the flywheel socket remains associated with the specially configured flywheel. The splining is formed to allow limited misalignment of the driving shaft and the driven drive train while an axial bore through the symmetrical shaft communicates lubricant from the drive train to the spline remote of the drive train.
