A crankshaft assembly for use with a connecting rod having a one-piece crankpin bearing support. The crankshaft assembly includes a first one-piece crankshaft portion having a first counterweight, a first end of a main axle extending outwardly from one end of the first counterweight, and a crankpin extending outwardly from the other end of the first counterweight. Similarly, a second one-piece crankshaft portion includes a second counterweight, a second end of the main axle extending outwardly from one end of the second counterweight. The second one-piece crankshaft portion also includes a crankpin receiving hole formed in the second counterweight. The one-piece crankpin bearing support on the connecting rod is positioned over the crankpin and, thereafter, the first and second crankshaft portions are secured together by press fitting the crankpin on the first crankshaft portion into the receiving hole on the second crankshaft portion. A method of manufacturing the crankshaft assembly is also disclosed.
