Plastic Drive Cup split

I took the four screws out of the ice basket and removed the plastic cup pieces. I then lifted the scress shaft up and put the new cup in. You have pull up very hard on the screw shaft and use two thin flat metal puddy knives to disingage the two plactic stays on each side of the shaft holder. The plactic housing around the screw shaft did not brake, however. I then put the screw shaft and the cup drive in place quite easily. Works fine.
