    • Here's a couple of pics of the beast. I was told on here if there aren't any pics, then it doesn't exist! And before anyone asks- yes, the smoke stack is now turned in the right direction. This was just after I got her home from Texas, to where I live in Michigan.      
    • Yeah. Let's hope it stays working. What I think the problem was is that the assembly that rotates the vanes inside the turbo was sticking. The tech at the dealership said he played with it a little bit, and that the actuator piston seemed to be working. My theory (and I could be just as wrong as possible) is that the rotating assembly that works the vanes was carboned up. Although the truck has relatively low miles (343,xxx), it has almost 15,000 hours. The truck was used in the oil fields to run a blower to unload incoming pneumatic trailers full of fracking sand. It basically spent most of its time the last few years (according to the previous owner) going between idle and 1100-1200 rpm's to run the pto.  It seemed the more I ran it at road speed, and spooling the turbo up, the more it wanted to start working. I've yet to put the truck to work. And probably won't do so for another couple of months. I still have a few things I need to do. Like fix a leaking heater core in the sleeper. And I'm going to post on that separately. I've also got to get a properly sized wet kit on it. I was able to sell the blower to a guy in the North Dakota oil fields. And I got really lucky that he didn't need the pto because he's running 9 Pete 379's with 18 speed trannys.  Which all of that is brand new. I don't know why, but the previous owner had it ALL replaced: the unit itself at the trans, the pto shaft, and the tower in the cab. Everything.  The unit will need to move enough fluid to operate the long cylinders on a sliding-axle trailer, and the motor on a 20,000 pound winch. I'm slowly getting her all ready to work. I have more questions on some things I need to fix yet. But I'm getting down to all small things now. At least I hope!  I'll try to get some pics of it up soon.

      hi.
      i think i found the ground block.
      would it be about 3x4 inch black.  has one nut terminal on one side and 4 terminals on the other side.
      found this under the center dash panel just south of the fuse box.   
      held down by 2 screws.
      i tried a test lite to check for ground or power and i got nothing.  key on or off.
      just dont know if that is the ground breaker box.
      thanks for any help
