Kysor fan clutch rebuilding video on You Tube

Found this animated video on You Tube that demonstrates how the fan clutch works. It explains a lot about it that's hard to understand because it works differently that most people expect because of it's fail safe operation.

I removed the first video I linked to because it just wasn't accurate enough for the clutch the HMMWV uses.

I know it was just to run them down, but using a 1/2" impact gun with reducers to 3/8" then down to 1/4" drive sockets for both removing and installing small bolts just seems like a bad idea to show people. You'll always end up with that one guy snapping off bolts because he wasn't careful.
