Are you sure it is a washer and not a dryer, sounds to me your trying to remove the pump off a dryer, they are cast iron and they have some kind of clip up inside to hold it in. The motor is cast aluminim and you can see the windings just by looking at it, the motor sould come right out. Also up on top were the controls are is sheet aluminim most of the time. Take the back off and pull all the wires out they are #2 insulated copper.
