Adapter for a corvette rear differential

摘要

An adaptor for an older Corvette drive train provides a structure for coupling the drive shaft extending from a front-mounted transmission to the differential of a C5 or C6 Corvette rear suspension in which the rear mounted transmission has been removed. A housing holds a stub shaft for rotation on front (outside) and rear (inside) bearings. The shaft has a coupling yoke mounted to its front end and engages the differential gearing at its other (rear) end. The housing mounts to the differential at the five mounting points of the removed transmission. A bracket which attaches to frame mounts can be mounted to either the top or bottom front (outside) face of the housing, depending upon the suspension-to-frame geometry. A circular flange on the shaft positions and holds the inside bearing and a rearward extending boss on the yoke positions and holds the outside bearing. A crushable tubular spacer fits over a portion of the shaft and holds the front and rear bearings apart during assembly and while the shaft assembly is drawn up. Two grease ports and fittings access the interior of the peripheral sealing ring to meet and seal the differential opening.
