Appliance repairmen help!

Oh and one more thing hooha........I cannot remember 100% but something sticks out in my mind about that nut that holds the coupler on being left hand thread. Just be careful when you try to loosen it up. I'm not for sure, but it would suck to break it so just gently tweak it and you can feel if it's gonna loosen up whichever way you turn it. I would go into it assuming right hand thread and just gently try to turn it. If it seems like it's gonna tighten up, go the other way.
