Abstract:
1. A method of centering a torque converter and an engine crankshaft at a connecting interface, the torque converter having a pilot with an outer end and a conical guide surface spaced inward from the outer end, and the crankshaft having a recess for receiving the pilot and a conical chamfer at an outer end of the recess, the conical guide surface and the conical chamfer being positioned in spaced opposing axial alignment upon connection of the torque converter and the crankshaft, the method comprising: providing an alignment ring having an annular body including first and second ends formed by axially spaced inner and outer coaxial conical surfaces extending between inner and outer peripheries, the body being formed of a material that is solid at room temperatures but is compressible when subjected to end loads beyond a prescribed limit; placing the ring onto the pilot; centering the torque converter to the crankshaft by inserting the pilot into the recess such that the conical guide surfaces of the pilot and the conical chamfer engage the conical surfaces of the alignment ring which operates to center the pilot within the recess; and fastening the torque converter to the engine while the pilot and the recess remain centered.
