Found a 270HP D8H locally in decent shape with a bad engine. It started knocking, so they tore into it and found a spun main bearing. They shined up the crank as much as possible and stuck a new bearing in it, which promptly spun again. Obviously it needs the crank turned and block line bored (big $$$).
Anyways, I can get it for scrap price. I don't really need another D8H, but I like a good project. I started doing some measuring and found the D342 and torque divider to be 102 inches long from fan to output yoke. I then took a measurement on an 855 Cummins with a 13 speed Road Ranger and it is 100 inches long from fan to output yoke.
Is there any reason I couldn't take the D342 and torque divider out and replace it with a 350 HP Big Cam Cummins and road ranger transmission? Just put the Road Ranger in 9th gear (1.57:1) with the Cummins at 2100 RPM and the output speed would be 1300 RPM - pretty close to the D342 at 1400 RPM with a little slip in the torque divider.
What would it take to make the powershift transmission work? The torque divider pump and torque divider scavenging pump would both go away. Would a single pump mounted on the engine be able to run the transmission and brakes and steering clutches?
