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.
