Abstract
An improved crankcase structure for engine blocks and the like, may be fabricated wherein the crankcase is initially cast or otherwise formed with bearing caps integral therewith. The caps are preferably secured by severable connecting portions unidirectionally longitudinally adjacent their associated bearing receiving portions in the transverse webs of the cylinder block. The complete crankcase is then machined and the bearing caps are separated for subsequent assembly to the crankcase in conventional fashion. Consequently, the invention reduces the amount of tooling and machining time and equipment required for manufacturing crankcases for engine blocks and the like.
