In order to avoid a bearing clearance causing noise, a core made of iron metal is poured at least into the bearing cap, said core, by means of a bearing area, directly surrounding the crankshaft journal of a crankshaft, and having lugs for bores connected by a transverse part. The bores are penetrated by the screws in order to fasten the bearing. | |
