To power the central pillar you need to get all the gears activated all around it. Do that, that'll power the pillar (you can tell it's been powered by the spinning pink ring). Then simply move the pieces back to how they were, and the pillar will raise, transferring the power to the control room. Insert the primed bar, flip the lever, hit the button. Viola, body bar. You need to repeat this small process per bar. It's also worth activating the infinite move counter, since then you never have to reset.
