The article is about the possibilities to diagnose the technical state of transfer mechanism of road motor vehicles. The diagnostic is done on a performance dynamometer, which measures the resistance of transfer mechanism during the coasting of rolling mass. The resistance makes itself felt like power losses by the movement of vehicle, which afects directly dynamical characteristics and fuel consumption. By the measurement we can quantify its value, what is the sign of the technical state of the mechanism.
