Abstract: Preload sleeves and/or other retainers for a collet-mounted blade dovetail and/or other root are disclosed. An example turbofan for an engine includes a trunnion forming a socket for a root of a blade, a primary collet positioning the root with respect to the trunnion, and a radial preload retainer at least partially encircling the primary collet and applying a radial force with respect to the primary collet to support the primary collet positioning the root with respect to the trunnion.
