Abstract
A method of making a molded track for use with a snowmobile having a suspension system equipped with slide rails consists of a series of steps that include preparing a mold press having a stationary inner mold and a movable outer mold with the inner mold displaying one or more rows of peripherally spaced recesses having a given shape, inserting in the recesses a series of slide bearing elements each having a generally flat portion having a shape corresponding to the shape of the recesses, laying one or more layers of rubber and fabrics on the inner mold and vulcanizing the rubber to form a molded track whereby the slide bearing elements are integrally formed with the molded track with one face of the flat portion of the elements being exposed so that it is frictionally contacted by a slide rail during use of the snowmobile.
