Features of the functioning of the technical service system of technological and transport machines and equipment, low quality and efficiency of equipment supplied to agricultural enterprises, technical services require urgent improvement of the system and mechanisms to increase the level of reliability and operability of the operated and new (supplied) equipment. The paper presents and substantiates the principles of improving the organization of technical service of machinery and equipment in the modern conditions of the functioning of the agro-industrial complex.

“…For the highly efficient functioning of ITS dairy farms at the design stage, it is necessary to ensure high accuracy and reliability of the calculation results. Therefore, it is expedient to ensure the collection of scientific information that fully reflects the real conditions of operation of technological machines and equipment of dairy farming and the results of the activities of farms and ITS livestock [3][4][6][7][8]. In the implementation of the tasks, research methods were used: analysis and synthesis of processes of production and technical service of equipment, computational and constructive in determining the scope of work on technical service and optimizing their distribution among IOP Publishing doi:10.1088/1755-1315/1231/1/012019 2 performers, probabilistic methods for studying the parameters of input and output flows of service requirements, abstract-logical, technical and economic assessments, etc.…”

The paper presents the results of the assessment of the technical and economic efficiency of the rational organization of technical service of livestock machinery and equipment with the participation of manufacturers of equipment. The authors analyzed the labor intensity and structure of maintenance and repair work for groups of technological machines and equipment; the costs of downtime of technological machines and equipment of dairy farming for a standard-sized number of farms and complexes. Specific values of indicators depending on the number of cows are determined.

An assessment of the quality of the control of the parameters of the crankshaft after processing for the repair size was carried out. The company's metrological support system must guarantee the accuracy and quality of the crankshaft repair, eliminating the possibility of defects during subsequent assembly. When repairing engines, defects in the crankshafts are detected, after which they are replaced with new ones or processed according to the repair size. After processing the crankshaft for the repair size, it is necessary to carry out control according to six parameters. It was revealed that to measure the diameters of the main and connecting rod necks of the crankshaft of the Zavolzhsky Engine Plant, as well as their ovality, it is necessary to replace the micrometer 50-75 (0.01) used at the enterprise, the maximum measurement error of which is twice as large as permissible, with a lever bracket 50-75 (0.002) to reduce the measurement error and improve the quality of control. To control the greatest beating of the second, third and fourth root necks relative to the first and fifth root necks, the hour-type indicator used at enterprises fully satisfies the specified conditions, the maximum error does not exceed the permissible one. To control the axial clearance of the already assembled crankshaft along the thrust bearing, dial indicator 0-10 (0.01) is also used, which provides the specified measurement accuracy with a three-fold margin. When measuring the length of the third root neck, the use of a caliper calipers 0-125 (0.05) leads to an excess of the permissible measurement error by 3 times, but there are no other more accurate universal measuring instruments to control this parameter, since the control is carried out by special sponges for measuring holes, which are available only for calipers. It is recommended to design a gauge to measure the length of the third root neck.
