The analytical assessment of change of office properties of heavy-duty details of friction pairs of the cart of the freight car on the first depot repair is presented. The technique of definition of iznos of details of the cart is applied to determination of faults. The most subject are shown to defects nodes of the cart of the freight car.

In this paper developed solid model of the cap of a side bearing. It made of cast iron of (ВАГР-113.00.00.006) Altai steel casting factory (ASCF). We simulated desing technologikal parametrs, wich give casting disinh without casting defects.
