ABSTRACT:
A method for aligning bearing covers at bearing sections of a crankcase in which bearing covers of a crankshaft bearing are aligned by way of fastening bolts and subsequently machined-in fitting pins and wherein the bearing bore for the crankshaft is subsequently machined. Thereafter, the crankshaft is assembled whereby the bearing cover is at first aligned by the fitting pins and is then fixed by means of the fastening bolts. Not only a secure support of the bearing cover at the bearing sections is assured thereby, but also narrow tolerances which favorably influence the bearing support of the crankshaft, can be maintained without problem.
