Abstract
A piston assembly for an internal combustion engine comprises a piston body having a head and a pair of pin bosses depending from the head having a pair of pin bores aligned along a pin bore axis. A piston skirt has a pair of opposed skirt portions and a pair of opposed side wall portions joining the skirt portions. At least one skirt retainer is supported on at least one of the side walls. The skirt retainer is biased axially inwardly along the pin bore axis in register with a corresponding one of the pin bores to connect the piston skirt to the pin bosses. The skirt connects with a snap-fit to the piston body.
