ABSTRACT:
A crankshaft bearing support arrangement is disclosed for an engine arranged such that the crankshaft is vertically oriented. The crankshaft rotates within a crankcase chamber defined by the cylinder block and a crankcase cover connected thereto. First web members which support half-bearings extend from the cylinder block. Mating half-bearings are supported by second web members position opposite the first web members. An oil flow passage is defined through the crankcase chamber generally opposite the cylinder block from a top end to a bottom end of the chamber. In one arrangement, the oil flow passage comprises individual passages through the second web members. In another arrangement, the oil flow passage comprises a space between an end of the second web members opposite the cylinder block and the crankcase cover. The crankshaft support arrangement allows lubricating oil introduced into the crankcase chamber to flow downwardly from the top end to the bottom end of the chamber for return to an oil reservoir for recirculation through the engine.
