Gotcha, I just took off the cover, had my buddy hod the fan and I unscrewed it. Was real easy, left the fan off and the cover, bogs the rhino down in mud and water. If u don't have an extra hand just take a half inch dowel rod or a 1x2 or something similar and wedge it in between a fan blade and the bottom of the skid plates, apply pressure with the socket and it should spin right off.
