Introduction
Machine maintenance is a complex of preventive measures in an interremmer period aimed at preventing failures in aggregates and nodes and a decrease in the intensity of wear of the details. Maintenance includes control and diagnostic, fastening, lubricants, filling, adjustment, electrical and other types of work.
Maintenance of cars has a goal: to ensure the constant technical service of aggregates, nodes in the car as a whole; maximize the interremmer runs; guarantee traffic safety; Ensure the minimum flow of operational materials.
To achieve these goals, our country adopted a planning and preventive system of maintenance, providing for the mandatory execution with a given frequency of the established complex of work during the use, storage and transportation of cars. The technological process of servicing the car with a planned warning system provides for a combination of mandatory work with the works performed by the need, the need for which is determined by checking the state of the car. Maintenance of special equipment installed on the car is carried out as possible simultaneously with the maintenance of the chassis.

Conclusion
During the work performed, a technical service scheme was developed in one post for the KAMAZ car 53212. The list of operations performed during the first maintenance, which includes 35 points. During maintenance, fasteners are performed, filling, adjustment, inspection work. Composed map-scheme for the arrangement of performers. The table of the main and additional equipment is drawn up. The graphic part of the course project is performed. The first part of which is the drawing of the car in two projections indicating the number and location of the operation. The second part is the scheme of the technological layout of the post with the placement of equipment and workers

Technological maps for maintenance and repair of cars KAMAZ (1989)
Introduction
Technological maps of the current repair of units developed "Centralythech" of Maintotrans of the RSFSR on the application of the manufacturing firm "Kamazavto Center" of the production association KAMAZ.
Technological maps are developed based on the following materials:
1. Regulations on the maintenance and repair of the rolling stock of automobile transport. Part 1 (guideline).
2. Regulations on the maintenance and repair of the rolling stock of automobile transport. Part 2 (regulatory). Cars of the KAMAZ family. The 200-RSFSR-12-0115-87.
3. Operating instruction manual KAMAZ type 6x4 (5320-3902002р7).
4. Author's operating manual KAMAZ type 6x6 (4310-3902002PE).
5. Guide to the current repair of cars KAMAZ-5320, KAMAZ-5511, KAMAE-4310 (workshop work). RT-200-15-0066-82.
6. Catalogs and drawings of parts and assembly units of KAMAZ cars.
In the development of technological maps, equipment, devices and tools manufactured by serial plants "Rosavtospiece" and non-standard equipment, including those designed for KAMAZ, are used.
Technological maps contain regulations of the complexity of work, coordinated with the "Center-RGTRUDAVTOTRANS" of Maintotrans of the RSFSR.
Technological maps have passed an experienced testing.
Technological cards are typical. In each case, their binding to the specific conditions of enterprises is necessary.
The nomenclature of repaired aggregates, nodes, mechanisms and devices is chosen based on the specific and most commonly found at the enterprises of the maintenance of KAMAZ cars.
The list of technological maps includes repairs: engine, fuel equipment, gas equipment, electrical equipment, pneumatic equipment of the brake system, dumping mechanism, transmission.
To facilitate reading technological maps, they contain schemes, drawings.
In technological maps, a complete list of disassembly, assembly and defecting operations are shown. Under the conditions of operation, the depth of disassembly and the volume of the defect can be carried out until the defect is detected.
When organizing and implementing work on the current repair of aggregates, nodes, mechanisms and instruments, it is necessary to be guided by the system of safety standards and "safety regulations for road transport enterprises."
The current repair of aggregates, nodes, mechanisms and devices should be performed in the workshops intended for this or in areas.
When disassembling units, nodes, mechanisms and devices, it is necessary to use pullers and devices that facilitate the work of the performers and ensure the safety of work.
The workshop of the current repair of aggregates must be equipped with the necessary lifting and transport mechanisms. Transport, remove and install from stands aggregates and nodes having a significant mass, followed by lifting and transport mechanisms equipped with devices that protect against the possible fall of aggregates and nodes.
Devices for fixing units and nodes on stands should exclude the possibility of offset or falling units and nodes. Tools and fixtures must be in good condition.
The procedure for holding work on the current repairs is set forth in technological maps, where the sequence of collapsible assembly, defective work and work on the test of aggregates and components, equipment, devices and tools, technical conditions, and instructions, labor-intensiveness and qualifications of the performers are reflected.
The technological process of current repair of units should include: Cleaning and washing cars; identifying faulty aggregates by car; Removing faulty aggregates from the car; Transportation in the workshop; subjoicing; External washing (cleaning); disassembly;
washing; cleaning, drying, blowing parts; Defecting; bundle; assembly; Test adjustment; ■ acceptance of OTB; Transportation to the post (warehouse); Staging on the car.
Only persons who have lost their safety instructions and traditional labor trained in special occupations organized by the enterprise, are allowed to work on the repair of aggregates, nodes, mechanisms and instruments.
In the workshops or on sites there must be first aid kits, equipped with medicines necessary to provide first aid.
