Abstract: A method for forming a transmission synchronizer friction surface includes the steps of forming a woven substrate fabric, oxidizing the substrate fabric, carbonizing the substrate fabric, densifying the carbonized substrate fabric, burnishing the densified carbonized substrate fabric, applying a thermoset adhesive to the burnished substrate fabric, and heating and pressing the piece of fabric against a conical surface of a synchronizer element. To form the fabric, yarn is formed of chopped substrate fibers, and the yarn is woven to form the woven substrate fabric. Densification is increased by extending a period of time of chemical vapor deposition to achieve a weight in an unburnished condition of at least 16 ounces per square yard for a thickness range of approximately 40 to 50 mils. Both sides of the substrate fabric are burnished. The material is pressed against the conical surface under a high pressure of at least 2000 psi to achieve the desired bonding of the substrate fabric to the conical surface.

Abstract: The floating wrist pin coupling for a piston assembly will rotate within a bearing assembly for an oscillating connecting rod as a piston cycles through compression and suction strokes. As the wrist pin rotates through 360 degrees, the bearings within the bearing assembly are lubricated and subjected to a rotary rather than an oscillating motion as the connecting rod oscillates.
