Maybe Lionel changed the front engine mounting design on the Legacy version from what they used on the JLC version. I've had the boiler top off also. Did you get an instruction book with the engine? That should show where the screws are that have to be removed in order to get the top section of the boiler to separate from the bottom part. They should be on the bottom of the boiler near the main driver on the front engine and under the cab in the back. There are several screws under the cab and its confusing as to which ones have to be removed. You may have to try loosening several until you find the right ones.
