A multi-piece crankshaft having a shaft with two ends, an axis and adapted to rotate about its axis. A crankpin also has two ends and an axis parallel to but spaced radially outwardly from the shaft axis. The crankpin optionally has at least one indentation. A plate has two spaced openings such that one end of the shaft is positioned in one of the plate openings while the other end of the shaft is positioned in the other plate opening. At least one counterweight extends between said one end of the shaft and said one end of the crankpin, and this counterweight is formed by casting a liquid metal around the ends of the shaft and the crankpin as well as around the plate. The liquid metal fills the at least one indentation and, upon hardening, locks the counterweight to the crankpin and shaft and encases the plate.
