Post Body

Hi all,

I'm replacing a discontinued MagneTek Century AC motor, part # 8-182703-01. I've found Grainger has two in their system that would be direct replacements, item # 61KN18 and 54JF90. However, there seem to be subtle differences between the two and I'm not sure which of these two would be more appropriate. Can anyone help me learn about this? Big note, I haven't a clue whether the old motor was clockwise or counter-clockwise and cannot find that info from searching for the old motor. 🤦🏻‍♂️
