FIELD: transport.
SUBSTANCE: in updating, traction motor components are dismantled. After dismantling, seat cut-out lines are marked with cut-out outline machining allowances. Sliding bearing attachment points are cut in marked lines. Cut-out outlines are machined. Lengthwise beams are welded to machined points to subject the housing to thermal treatment and mechanical processing of lengthwise beams for attachment of housing of said axial rolling bearing and mechanical processing of seats for end shields. If required after welding said lengthwise beams, housing lengthwise elements are recovered. Besides, necks are soldered in place before thermal treatment.
EFFECT: longer life.
