Engines that equip self-propelled tractors and combines are diesel engines. These engines have a construction adapted to working over a wide range of speeds and powers. This ensures the operation of all agricultural machines. However, the areas of economic use are more restricted, which is why agricultural aggregates should be properly made up and exploited to fit into them. The tractor engine is used at maximum speed regime when it has maximum power requests or when operating machines is also necessary from the independent power source. The studies in this work were carried out on a D-110 Diesel engine, an engine that equips the U-650M tractor. Studies refer to the dynamics of the motor mechanism. The parts of the engine mechanism studied were: the cylinder, the piston, the piston bolt, the connecting rod, the crankshaft, and the steering wheel. In each of these parts, the size and weight were measured. For the calculation of the operating indices of the D-110 engine, measurements were made on a stand to try and roll internal combustion engines.
