I have a krups 574 blender. The male part of the gear that inserts into the jug is made of rubber and was shaved off one time when the jug was not properly attached before the blender was turned on. I would like to order the part which I believe is $10 but I believe I need to undo the screws at the bottom of the blender to detach the gear. The screws seem to require a special tool. How would I locate such a tool?
