A press including a flywheel which is axially shifted along the quill to which it is rotatably mounted from an idle position to an engaged position during engagement of the flywheel by the clutch connected to the press crankshaft, and which is axially biased to the idle position when the clutch is subsequently disengaged. The press includes a rigid drive disk, connected to the flywheel for rotation therewith, that is engaged by a clutch mechanism to drivingly couple the press crankshaft to the flywheel. The rigid drive disk and the flywheel are both axially shifted during clutch engagement. Spring elements between the quill or non-rotating press frame and the flywheel are compressed when the flywheel is so shifted, and these spring elements return or axially shift the flywheel and drive disk to an idle position when the clutch mechanism is subsequently disengaged.
