ABSTRACT:
A piston head has a top extending radially about a first axis and first and second pin bosses depending downwardly and defining first and second pin bores. A connecting rod includes a fork having first and second connecting bosses spaced apart from each other and defining first and second connecting bores. A piston skirt extends cylindrically and includes a bridge extending diametrically through the first axis defining a skirt bore for axial alignment with said pin bores and said connecting bores. The bridge is disposed between the first and second connecting bosses, which are disposed between the pin bosses. The pin bores are axially aligned with the connecting bores and with the skirt bore. A wrist pin extends within the pin bores and the connecting bores and the skirt bore along the second axis to interconnect the piston head and the connecting rod and the piston skirt.
