Abstract: A process for measuring an unbalance of a torque converter, in which an outer member and an inner member of the torque converter are assembled, and oil is filled into the outer member to establish a condition similar to an actual service state of the torque converter. In this condition, the two members are rotated in unison. If the rotational speed of the torque converter reaches a measuring rotational speed, a plurality of measurements are conducted with the phase of the outer and inner members being varied between each measurement through a predetermined angle, thereby correctly detecting only an unbalance due to the outer member, with an unbalance due to the inner member being canceled from the results of the measurements. Cutting a balance weight having a weight sufficient to correct the detected unbalance from a metal tape and attached said cut balance weight to an outer periphery of the outer member of the torque converter at a given position by spot-welding or adhesive-bonding.

Abstract: The present invention provides a method and apparatus for assembling an insert assembly in a catalytic converter comprising a casing and an insert assembly therein. The insert assembly comprises a columnar catalyst having a seal mat wound around the outer periphery thereof and a mesh ring attached thereto. The seal mat is fitted in a groove provided in a receiving member for the placement of a catalyst and the catalyst is placed and positioned, with its axis substantially horizontal, on the receiving member. A guide member is positioned adjacent to the catalyst on the same axis as the catalyst and supported from the sides thereof, the guide member having an outer inclined surface enlarged towards the catalyst. The mesh ring is positioned on the same axis as the catalyst on the side of the guide member opposite to the side of the catalyst. The opposite end of the seal mat are engaged to wind the seal mat around the catalyst and the mesh ring is resiliently supported from the outside thereof.
