Abstract
A method of operatively coupling an engine connecting rod having an annular opening for a connecting pin with a piston defining apertures in spaced apart pin bosses with the apertures sized differently than the annular opening by use of a connecting pin having a non-uniform diameter, including: first heating the piston so that the apertures in the pin bosses are expanded; chilling the connecting pin; inserting the connecting pin through one of the apertures, the annular opening, and the other aperture; and returning the three parts to ambient temperature conditions so as to axially secure the connecting pin between the spaced shoulders.
