For sale is a complete medium-duty drivetrain package removed from the same truck, including a DT466 diesel engine, Allison MT643 automatic transmission with PTO, and a Rockwell RA-44-S-1 rear drive axle with Eaton 2-speed. The engine was professionally checked and verified to be in good condition, has a brand-new BorgWarner turbo, and the injection pump is believed to be rebuilt, making this not a core engine. The Allison MT643 is a proven heavy-duty transmission with PTO capability, and the Rockwell RA-44 Eaton 2-speed rear is a desirable vocational axle commonly used in dump trucks, farm trucks, and work rigs. This setup is ideal for a truck replacement, farm use, equipment build, or custom diesel swap. Selling as a complete package.
