This article discusses issues related to the scientific and methodological problems of the acceptance of the machines for repair and their solutions. The production process of machinery repair is a set of human actions and manufacturing instruments, performing in a certain sequence and providing recovery, serviceability and full (or near full) resource products. It consists of a series of technological processes. External cleaning, washing and inspection repair is among the most important technological reconditioning processes. During the period of Russia's regional associations and specialized departments "Agricultural machinery" all tractors, automobiles, appliances and machines when accepting in the overhaul or issuing from it had to met the "technical specifications for delivery in overhaul and the issuance from the overhaul of tractors and self-propelled chassis, engines, their units and assemblies" (TU 70-260-71). The machine must be complete. At present, the institutional conditions of delivery vehicles and other mechanisms for repair in the technical service has changed substantially. However, technical requirements cannot and should not be significant changed, since the conditions of vehicles operating mechanism and require the highest quality as the machine as a whole and its parts. The article considers the basic requirements and ways to optimize the process of acceptance in the repair of vehicles through the example of special-purpose vehicles as part of their technical service.
