Photographs of Porsche 356 assembly and inspection

The worker above is assembling a bearing roller crankshaft.  This is a very precise and difficult task Advantages of this kind of design is that it allows the crankshaft to rotate with less friction, and it doesn't need to operate with constant oil pressure as plain bearings do. To rebuild one of these you have to split the crankshaft in pieces as it is held together by serrated pins and bolts. You need special jigs and dial indicators to do this.
