Abstract
In a weld-coupling portion 3 which is formed by fitting an inner peripheral surface 2b of an end portion of a pump shell 2 to a lower-step surface 4a of a stepped portion 4 formed on an outer peripheral surface of an end portion of a front cover 1 of a torque converter and then welding them together while abutting an end surface 2a of the end portion of the pump shell 2 with a stepped surface 4a of the stepped portion 4 of the front cover 1, the weld-coupling portion 3 is cut down to a level of the lower-step surface 4a of the front cover 1 in such a predetermined cutting width as to evenly cut a front cover side and a pump shell side of the weld-coupling portion 3 in order to separate the front cover 1 and the pump shell 2 apart. A new replacement of the pump shell 2N which has an end portion whose length is larger than that of the end portion of a cut pump shell 2C (not illustrated) by the cutting width W is fit to the lower-step surface 4a of the stepped portion of the end portion of the cut front cover 1C. The end surface 2a of the end portion is abutted with the stepped surface 4b of the end portion of the cut front cover 1C to thereby weld-recouple the cut front cover 1C and the new pump shell 2N.
