ABSTRACT:
The method of manufacturing a single crank crankshaft (92) includes forging or casting a double crank (50) with two main shaft sections (54), with a common crankshaft axis (56), a crank web (58) integral with an end of each main shaft section (54) and a drive stud (60) integral with both crank webs (58) and having a drive stud axis (62) that is parallel to and spaced from the common crankshaft axis (56). Flat end surfaces (64) are machined on the ends of the main shaft sections and recesses (66) for machining centers (68) are drilled in each end of the double crank (50). The double crank (50) is then mounted in machining centers (68). A bearing engaging surface (70) and an axial locating surface (74) are machined on each crank web. A bearing engaging surface (76) is machined on each main shaft section (54). A seal engaging surface (78) is machined on each main shaft section (54) and splines (88) are formed on each end of the double crank (50). A long bearing engaging surface (82), concentric with the drive stud axis (62), is machined on the drive stud (60).
