ABSTRACT:
A frame for supporting a crankshaft has two supports with depressions for holding the shaft of a crankshaft to permit rotation of the shaft. The supports are placed in a frame that has two arms with brackets that hold the supports against the arms. The arms are connected parallel to each other by a connecting bar that may be adjustable in length. The connecting bar may be telescoped for adjustment and provided with a locking device, such as a threaded screw and nut. In a second embodiment, the arms are connected by a plate.
