Abstract
This invention relates to a chain guide rail for an internal-combustion engine, having a body portion and a pin, both made with a first material, an overmolding of a second material which covers both the pin and the body portion, and a longitudinal axis through the length of the guide rail. The pin, inserted into a housing recess in the internal-combustion engine, is restrained from moving perpendicular to the first longitudinal axis but is free to move parallel to the axis. Preferred embodiments of the present invention utilize a fastener to hold the guide rail to the housing. Preferred embodiments also utilize raised portions spaced along the guide rail which reduce the longitudinal shrinkage during cooling of the second material.
