A compressor assembly that includes a driveshaft and at least one eccentric press-fit to the shaft. In one embodiment, the driveshaft includes an opening at a first end and the eccentric includes a linking rod press-fit into the opening. During assembly, the first end of the shaft is inserted through an opening in a rotor and the eccentric is then press-fit to the first end. This arrangement allows the opening in the rotor to closely receive the driveshaft and allows the eccentric to be assembled to the compressor without passing the eccentric through the rotor opening. In use, the eccentric is operably engaged with a compressor mechanism such as, for example, a rotary compression mechanism, a reciprocating piston mechanism, or an orbiting scroll mechanism. In one embodiment, a second eccentric is press- fit to a second end of the driveshaft and is operably engaged with a second compressor mechanism.
