FIELD: mechanical engineering; repair of engines. SUBSTANCE: liner to be treated is installed coaxially into housing provided with punch and is subjected to upsetting by radial pressure relative to liner uniformly over entire length of liner. Device for executing the method is made in form of housing and flexible diaphragm rigidly interconnected to form hermetically sealed space in between. Space is filled with working liquid and is connected with hydraulic system. Resilient elements are made in form of set of rigid strips connected by flexible elements. Device can be made in form of housing with hydraulic cylinders accommodating plungers installed for radial reciprocation relative to housing. Resilient elements are made in form of set of pressure strips secured on plungers. EFFECT: improved quality of reconditioning owing to prevention of cranking of liner material, enlarged technological capabilities owing to possibility of reconditioning of liners made of any materials. 4 cl, 2 dwg
