The partion between the tub and dispenser broke

Once I got the correct part, (the expanded view of the icemaker is confusing as it shows the partition at the back of the diagram) I removed the ice dispenser from the tub by removing the screws and disengage the tabs holding the dispenser assembly in the tub. The most difficult step was getting the disenser disengaged from the tub. I used two kitchen knives to wedge between the walls of the tub. It was then easy to remove and replace the broken inside partition and reassemble the dispenser. Works like new.
