An eccentric shaft particularly for driving a large reciprocating pump, and a method of making the shaft. The shaft includes an elongated cylindrical body, a plurality of small eccentric discs uniformly spaced along the length of the body, and optionally one or more concentric gear flanges, all formed as a single integral forging. Relatively large eccentric discs are shrink-fitted and keyed to the small eccentric discs.
