KitchenAid tub

[Boman]

Model - KAWE660W

Whats the secret to getting this inner tub out so I can change the gasket?

I thought I knew how, but when I try to shake the tub loose with the nut removed, the motor and all moves with it. Looks like there are 4 protrusions toward the bottom of the tube.

This thing has a bad leak, and I need to get it apart to check the gasket. Help!

Have another question about this type of machine, but will make another post.
