ENGINE DETAIL
The McCormick-Deering TD-40's unique starting system allows for the utilization of gasoline for initial ignition before switching to diesel, enhancing cold-start performance. With a displacement of 460.7 ci and a compression ratio of 15:1, this tractor delivers robust torque at lower RPMs, making it suitable for heavy-duty agricultural applications. However, the manual cranking operation may present challenges in convenience and safety, necessitating operator familiarity with the starting procedure.
| Description |
International Harvester diesel 4-cylinder liquid-cooled vertical I-head The TD-40's diesel engine was started on gasoline and then switched to diesel. The engine was manually cranked from the left side, which supplied fuel to a spark-ignition combustion chamber. Exhaust gas from this chamber was directed into the cylinders of the diesel. At 700 RPMs the gasoline chamber shut down and the engine ran as a true diesel |
