Anyone remember back to page 70 when I lost my fan clutch? The same thing just happened to Adventure Driven's M1079 only he was much further away from home than I was when mine happened. It sounds like he was able to source all of the newer parts and will hopefully be back on the road tomorrow but it's an abject lesson (repeated) as to the inferior design of the older clutch/fan set up. If you have that style, where the fan is sandwiched between the clutch and an aluminum spacer and an aluminum center to the actual fan, you'd be miles ahead, literally, to change it out while it's in your drive way and not hundreds of miles from home.
As an aside, whether related or not, he just had AC added last week. That's about the same time frame of my AC install and fan clutch grenade. Whether that's a coincidence or actually related is hard to tell but any time you have your cab tilted reach in and shake the fan to make sure it's still solidly mounted and not starting to wobble.
