you don't have a torque converter, just a cent clutch with a pulley instead of a sprocket.
to remove the clutch you must remove, or slacken the belt.
either remove the rear pulley, loosen the engine mounting bolts and slide the engine back if you can, or slide the axle forward if you can.
also, as jrmints said, remove any set screws still remaining. it should come off after the belt and all bolts/ set screws are removed.
