Maintenance and repair of motor transport

For the uninterrupted operation of the car throughout the entire period of operation, each car owner should from time to time carry out a set of certain works relating to the nature and purpose of the two groups:

- work aimed at maintaining the nodes of working mechanisms and units in working condition for a long period of operation;

- work aimed at establishing mechanisms, units and aggregates of machines.

Therefore, maintenance and repair of road transport in the first case is preventive, and in the second - recovery.

In our country, there is a preventive-planned system of compulsory maintenance and repair of the car. The meaning of it is that the maintenance and repair of cars carried out and according to the plan and on demand.

Maintenance (maintenance) of the car - electrical and adjustment, refueling, lubrication, fastening, control and diagnostic, cleaning and washing, as well as many other types of work, which are often performed without removing individual mechanisms, assemblies and dismantling of units from the car. However, if during maintenance, the complete serviceability of the individual components remains questionable, they are removed from the vehicle and checked on specialized stands and devices.

Periodicity of maintenance directly depends on the list and complexity of repair of the car and its units. That cars are divided into several types: seasonal, first and second, as well as daily maintenance.

The current legislative acts provide for maintenance and repair of motor vehicles and their units in two types - capital, carried out at special enterprises, and the current one, which is carried out at motor transport enterprises.

Each of the types of maintenance includes strictly established operations (work), which must be carried out. These operations are divided into executive and control components.

The executing part is often performed as required, and the control part of the work, which is often called diagnostic, is mandatory. This helps to significantly reduce both labor and material waste for the maintenance and repair of road transport.

Diagnostics - part of the technological process of routine maintenance and maintenance of cars, which provides a general picture of the state of the machine.

Daily maintenance and repair of motor vehicles (if necessary) must be performed every day on the return of the car from the work line. It includes:

- control and inspection work on all major systems and mechanisms that are responsible for safe movement, as well as lighting devices, cabin and bodywork;

- washing and cleaning and wiping-drying operations, as well as refueling the machine with coolant, compressed air, oil and, of course, fuel.

Car washing is carried out on demand.

Current repairs are performed at service stations and at trucking enterprises. It consists in the elimination of minor faults, as well as the failure of the machine.

During current repairs, the replacement of the units by the car occurs when the repair time of the unit is longer than the period necessary to replace it.

Capital repair of the car or the unit assumes complete disassembly of the parts and components that they try to repair and, if necessary, replace. After that, the aggregates are collected, tested and sent to the assembly.

For the entire lifetime of a full-sized car often undergoes one major overhaul.
