Abstract
A torque converter, including: a washer for a thrust bearing, the washer including a first circumferential surface facing radially outward; a stator hub with a second circumferential surface facing radially inward and free of an interlocking engagement with the first circumferential surface; and a shell for a turbine, the shell including a third circumferential surface facing radially inward. The washer is radially inwardly retained by contact between the first circumferential surface and the second or third circumferential surface. In a preferred embodiment, the washer is radially centered by contact between the first circumferential surface and the second or third circumferential surface. In another preferred embodiment, the hub includes at least one radially inwardly extending protrusion and the washer is retainable in an axial direction by the at least one protrusion.
