FIELD: mechanical engineering. SUBSTANCE: prior to facing of journal box body, it is loaded by elastic deformation in direction of jaws with simultaneous checking of loading force. Then successive facing of guides is performed in loaded state, over diagonals with forging of every joint made. Upon expiration of certain hold time and intermediate natural cooling in loaded state for 30 min, facing of supporting surface of journal box body is performed. Facing of surfaces is carried out with due regard for machining allowance. EFFECT: enhanced efficiency of restoration. 3 dwg
