Abstract: Apparatus is disclosed for preloading a thrust bearing disposed for carrying axial loads between a first member and a second member of a torque converter that are rotatable relative to each other about a central axis. The apparatus includes a first race assembly carried by the first member and disposed on one side of the thrust bearing. The first race assembly includes a fixed race having a radial bearing surface adapted to engage the bearing. A second race assembly is carried on the second member and is disposed on the other side of the thrust bearing. The second race assembly includes a floating race, a support ring, and a plurality of coil springs. The support ring has an annual groove with a bottom face disposed toward the thrust bearing and a plurality of apertures opening into the bottom face. The groove is adapted to receive the floating race and the apertures are adapted to receive the coil springs.
