We had an interesting weekend. It started out Saturday with fabbing up a custom soft tail airbag system for my leaf springs. A friend of mine from the Cummins forums came over and helped out. After we wrapped things up for the day, We took a ride in his Cummins converted F350.
It pulls very nice! I picked a route with a good hill on it to show off his exhaust brake. On the way up, The clutch disc came undone!

He called AAA and had it towed back to my house. The truck got there at 9 PM, he had the dinner my wife had cooked for us, and we went to work. By 11:45 we had clutch in hand and knew what the problem was. We were both worried we had twisted off the input shaft on his ZF6 transmission.
The next morning I call parts houses and we are out of luck. Turns out I was calling the wrong place. Our forum friends had a pile of stock clutch parts and gave us one. :thumbsup:
It was a couple of hours of driving round trip to get it.
We got it back together that afternoon, welded up some things that needed attention and sent him on his way.
At first look, we noticed the springs look like they came out of a rock tumbler.
I ground off the rivets and knocked it apart for a closer inspection:
OUCH!
Stock clutches are not all they are cracked up to be
His truck, looking much better back on the wheels. It is a real custom rig, a 2000 truck with a 2006 front end, 12V Cummins with twin turbos, Hamilton camshaft and valvetrain. ZF6 transmission with 4WD transfer case with a gear vendors 2 speed behind that. 5" exhaust with 5" remote mounted exhaust brake. Too many small mods to list. Yes, he is getting a proper aftermarket clutch to better match the 450 HP and 950 ft pounds of torque
