In this chapter the description of checks and the adjustments necessary for maintenance of high operational qualities of the car, profitability, movement and durability safety is resulted.
To provide reliable work of the car during all period of operation, make maintenance service in due time. The Manufacturer establishes the periodicity of maintenance service resulted more low.
If the car is maintained under trying conditions, for example, at the raised dust content, with the trailer, on small speeds or at a considerable quantity of trips on short distances, it is recommended to reduce intervals between maintenance service.
In the event that maintenance service is carried out irregularly, normal work of units and car devices is broken. Especially it concerns the engine of the second-hand car which was not exposed to regular or timely checks. In such cases besides periodic maintenance service it is necessary to execute additional наладочные works.
If there are suspicions on deterioration of the engine for reception of the preliminary information on a condition цилиндропоршневой engine groups check up a compression. On the basis of these data it is possible to receive representation about volume and degree of complexity of forthcoming works. If, for example, results of measurement of a compression obviously specify in strong deterioration of the engine routine maintenance will not lead to restoration of normal operational qualities, and all works will appear inexpedient. Major repairs with full dismantling is required to such engine.
Irregular service can become the reason of bad work of the engine. In that case execute the following:
– Clear, examine and check up the storage battery;
– Check up levels of oil and cooling liquid, if necessary add;
– Replace spark plugs;
– Check up a condition and a tension поликлиновых belts;
– Check up a condition of the air filter, if necessary replace it;
– Check up a condition of all hoses (branch pipes) and their tightness;
– Check up a condition of a cover and a rotor of the distributor of ignition and high-voltage wires, if necessary replace the worn out details;
– Check up electrical supply system;
– Check up the power supply system.
Amounts of works of the maintenance service which is carried out according to recommendations of manufacturer are more low described.
