I am a bit confused. Most of us call the wheel that receives power from the belt, the balance wheel or hand wheel.
"down there" and hitting drawers sounds like you may be talking about the big wheel that is connected directly to the treadle and powers the hand wheel. A pic would be nice. If you are talking about the big wheel underneath, there are at least two ways they are connected to the Irons ( frame). My W and W came as only a head. Sorry.
