Abstract
An assembly includes a polymeric member and a unitary metal casting. The metal casting is engaged with and relatively moveably capturing the polymeric member on the metal casting. The polymeric member includes an opening extending through the polymeric member. The opening defines a rotational axis of the polymeric member and includes a central cylindrical portion and first and second end portions having diameters greater than the central cylindrical portion. The first and second end portions are disposed proximate opposite ends of the opening, and the metal casting substantially fills the central cylindrical portion and the first and second end portions of the opening, thereby rotatably disposing and axially capturing the polymeric member on the metal casting. The assembly can be adapted for use as a crank arm in a transmission shift mechanism.
