Hypothetical question about a fan clutch

[Ironhead]

It is the kysor style, I have a new one but I guess a scared the gremlin away, right when I was fixing to take the allen bolts off I found I didnt have the right socket. So I put it all back together and started rolling to the next place I can get the 5/16 allen and the darn thing started working again. It still spins a little engaged but I have the stuff to replace it now. Thanks everyone for the input
