The crankshaft is liable to deformation due to inaccurate positioning of its main journals in the bearings. This article presents results of simulated tests of such deformations. The test results and methods for the verification of crankshaft mounting in the main bearings are assessed. A new method of measurement of crankweb deformations is proposed, the so called symmetric method, that allows the correct assessment of the condition of the crankshaft mounting in the bearings.
