Walkthrough
Once at the rear of the huge mechanism, walk down the stairs all the way until you get to the gear and steam wheel. Pull the lever on top to lower the gear and lock it into place. Turn the wheel to lock the fins below into a fan position to generate energy.
Go up a level, and engage the gear by turning the wheel and holding it until it fully engages. Head over to the panel here, and look behind it - the Cyrillic lettering will be important later. Head over to the center platform, and enter it. Connect the connecting sleeves with the pumping arms by throwing the switch. You can move the platform by holding the button over the lever, and choosing a direction to move.
