FIELD: mechanical engineering. SUBSTANCE: method includes preliminary formation of auxiliary bushing, mechanical working of conjugation surfaces to be restored and coupling of auxiliary bushing with conjugation parts. Auxiliary bushing is obtained by bending of sheet material and placing of workpiece obtained in body hole so that auxiliary bushing end protrudes beyond chamfer preliminarily made in body hole. Then beading pf the end is performed in body hole chamfer. Prior to applying force for displacement of bushing into auxiliary bushing hole, through slot is made in bushing, the latter is installed with interference fit in operating mandrel, with starting section protruding from operating mandrel. Bushing is then fixed in auxiliary bushing hole by means of starting section. EFFECT: enlarged production capabilities. 2 cl, 4 dwg
