Abstract
A blade for a torque converter, including: a body with first and second blade side surfaces and a blade edge surface connecting the first and second blade side surfaces; and a tab extending from the blade edge surface and arranged for insertion through an opening in a core ring for the torque converter. The tab includes: a distal end furthest from the blade edge surface; first and second tab edge surfaces in communication with the distal end; and first and second indentations in the first and second tab edge surfaces, respectively, between the distal end and the blade edge surface. The core ring forms at least respective portions of respective inner circumferences for a turbine and pump for the torque converter. After insertion through the opening, the tab is arranged to be bent along a line connecting the indentations so that a portion of the tab engages the core ring.
