Abstract
Methods were developed for elimination of deformation of crankshafts of car engines caused by wide-layer hardfacing at their reconditioning. It is established that an effective method to eliminate deformations is preheating of hardfaced bearings and (or) application of axial tensile load to the crankshaft during hardfacing.
