I am using an Electrolux washing machine for 19 years. Since it has become noisy, I ordered for repair work today.
Now I watching the outer drum from back side.
This large Y shape die cast part supports bearing of inner drum -we always see-.
The repair work was to replace this large part with 3 points puller.
As the repair staff say, this is a big old part, perhaps it may be the last one in Japan.
Sorry that the lighting is very poor, but this is my real life pic.
