Nub's Tomb

I am in the Nub's Tomb level. I am in the part where you chase Volodnikov. I trapped him with that stattue, and get the bronze gear. I put it in the turtle thing, but I can't figure out what to do now. Please help!!

Once you put the bronze gear in the elevator, push the block into the elevator...then a platform to the left of the elevator rises up...levitate up and whip across to the platform and ride it down to the next room...careful once in there!!!
hope that helps!!
