Progress has been slow on the Oshkosh, but this was a great milestone to see it rolling under its own power!

The new transfer case works great, but turned out to be from a 3-ton truck, so I had to swap the output shafts and yokes to match the driveshafts. Very nice not having decided what to put over the frame rails - easy access for t-case installation!

Here’s a list of what I’ve been up to on this project so far: oil &filter change, coolant hose replacement and system flush, installed the t-case and driveshafts, removed rotted air tanks, and cut off a battery box that had been welded to the frame. Like I said, slow progress.

That's a great project, I love old all wheel drives. What engine is in it ?

Hi Jeff, the engine is a Cummins JS-6 with a gear driven blower and PT fuel system. The audio in the video came through poorly, but this thing sounds really nice around 1500-1800 rpm!

I thought it was a J series Cummins but I wasn't sure. Great truck !

Ease of access for the transfer case and the tools to make it happen!

Looks good playing in the snow.

More tinkering on the Oshkosh this weekend - checked/changed the oil in both axles and all 3 gearboxes. Hooked up the parking brake, and scrounged and installed a bumper from a Dodge M37. The bumper is a little narrow, but the shape compliments the rest of the truck much better than the channel iron that it came with. Next task: brakes. The right rear brake is dragging badly, so somehow I have to remove and free it up.
