The expandable center spray, spray arm and support are a one piece deal like some of the GE style built dishwashers are.
Spray arm parts link
This spray arm is threaded into a part under the tub/liner of the dishwasher. A rubber coupler on top of the motor and pump assembly is what this spray arm assembly screws/threads into. To change/remove this spray arm, simply push a flat screwdriver through the hole in the bottom of the spray arm and twist it off. It should be a regular thread.
