What is carried out while 1. Maintenance of trucks: frequency, scope of work and general recommendations

20.06.2019

It's good when the car is trouble-free ready to travel at any distance. And to ensure this reliability allows Maintenance- regular, thorough, carried out in accordance with the instructions of the manufacturer of your model.

Types of maintenance

All car care activities are divided into 3 main categories of severity, but (this is important!) they are all part of the whole. Proper comprehensive maintenance consists of:

daily , which includes visual inspection, elimination of malfunctions detected during it, replenishment of working fluids, checking the performance of the steering and lighting fixtures, cleaning the body, interior, wheels, air filters etc.;
periodical , which is a series of activities aimed at identifying possible faults with the elimination of their causes, and subdivided into two more categories - TO-1 and TO-2;
seasonal , which is held twice a year, before the start of the summer and winter seasons, and consists in preparing the car for them.

Most often, the owner of a car does not even think that replenishing the tank and putting things in order in the cabin, he actually conducts daily maintenance, and changing winter tires for the summer, it performs part of the seasonal one, which, by the way, can be successfully combined with the next TO-2. But if the difference between daily and seasonal service is obvious, then the differences between the two types of periodic service often remain a mystery, especially for novice drivers. To understand what the main differences between TO-1 and TO-2 are, it is necessary to clearly understand what activities are included in each of them.

Features TO-1

TO-1 (first maintenance) is carried out every 8-10 thousand kilometers. The exact dates are indicated by the manufacturer in the accompanying documentation for the car. It is important to remember that these instructions are only recommendations and apply only to gentle operation. vehicle. That is, when using the machine in adverse conditions, aggressive driving style, increased vehicle loads, frequent off-road driving and other conditions that lead to rapid wear parts, assemblies, mechanisms, it is necessary to reduce the intervals between the next TO-1. Simply put, if you want your car to be always on the go, carry out TO-1 regularly and as often as possible.

The list of works included in TO-1 is quite extensive, but many of them do not require special labor costs: they can be carried out on their own - if you have experience, time and desire. The first MOT includes the following activities:

the whole complex of EO (daily maintenance);
checking and, if necessary, adjusting the pedal stroke, the reliability of the fasteners, the condition of the steering, wheels, brake and other systems;
idle speed adjustment of the crankshaft;
control of the level and composition of exhaust gases;
alternator belt adjustment, replacement of worn ones;
elimination of defects identified during inspections.

Every second TO-1 should be expanded:

checking the battery and cleaning it;
checking the condition of the muffler and suspension mounts;
checking the tightness of the cooling system;
tightening the flanges of the axle shafts and hubs;
cleaning the air and replacing the oil filters;
adjusting the headlights.

Features TO-2

TO-2 (second maintenance) is carried out less often than the first, but differs from it in labor intensity and scale necessary work, since the goal is to identify all possible malfunctions, worn parts, adjustment failures and eliminate the detected shortcomings. To maximize the effectiveness of such activities, it is recommended to complete diagnostics car.

The frequency of TO-2 is approximately every 16-20 thousand kilometers. In the presence of adverse factors, it would be more rational to reduce these intervals.

The list of works required for TO-2 includes full list TO-1 measures, as well as a thorough inspection, verification, adjustment of all components and systems of the vehicle, followed by the elimination of detected malfunctions. The labor intensity and responsibility of the second maintenance require experience, professionalism, and most importantly, the availability of special equipment, tools and conditions, therefore TO-2 is recommended to be carried out in service centers with a good reputation.

Thus, TO-1 and TO-2 are steps of the same ladder, and not mutually exclusive elements. It is necessary to strictly follow the maintenance schedule, which in the future may look like this:

Timely and thorough carrying out of the next MOT is a guarantee of durability and reliability of your car!

Regulate the operation of the carburetor at low speed modes crankshaft engine.

Maintenance No. 2 (TO-2).

The second maintenance (TO-2), in fact, has the same goals as the daily maintenance (EO) or maintenance No. 1 (TO-1). Maintenance operations No. 2 (TO-2) are recommended to be carried out at least once a year. The main difference lies in the complexity and volume of work. Fixing, lubricating, diagnostic and adjustment work, V this case are carried out with the removal of some details. Before performing TO-2 or in the course of it, it is necessary to carry out in-depth diagnostics of all the main units, components and systems of the vehicle to establish them. technical condition, determining the nature of the malfunctions, their causes, the possibility of operating this unit, unit or system. Inspection and maintenance constituent parts produced using special equipment.

Diagnostics D-1 and D-2.

One of the elements technological process Maintenance and repair is a diagnostic that serves to determine the technical condition of vehicles, their units and assemblies without disassembly. The specific property that distinguishes diagnostics from the usual definition of a technical condition is not an increase in the accuracy of its assessment, but the identification of hidden faults without disassembling the car. Currently, there are two options for performing diagnostic work: together with maintenance and repair, or at specialized posts and diagnostic lines.

Diagnostics D-1 is used to check the units and mechanisms that ensure traffic safety. This type of diagnosis is performed before TO-1. It is justified to carry out control and diagnostic work before TO-2 in the zone or at the diagnostic post in order to regulate the technological process and separate from the mass of cars entering TO-2 those that have a significant volume technical work great labor intensity. This type of diagnostics is called in-depth diagnostics D-2, performed at the post using a stand for checking the traction qualities of cars. During the inspection, problematic components, assemblies of the car are identified.

Many motorists who buy a car from the salon are faced with mandatory routine maintenance. No, of course, you can refuse them, but in this case, the warranty on the vehicle is lost. TO-1 and TO-2 are the recommendations of the manufacturer, and not an advertising move by dealers of a particular brand. After all, many drivers regard TO-1 as such. The list of works is much more expensive than in another service station, but now this is not about that.

General information and information

Planned is necessary for the timely detection of malfunctions of electronic and mechanical systems vehicle in order to eliminate them. Maintenance work is also carried out. fuel system, which allows you to slightly reduce fuel consumption during vehicle operation.

A new car is necessary to eliminate the so-called "hidden" faults. Not everyone will be able to notice the factory defect of the engine or brake system. If you leave all this without attention, you can get into an accident. Therefore, keeping the car in good technical condition is simply necessary. The technical condition of the vehicle is maximum level safety, comfort and economy that this vehicle can provide. Therefore, if you want to keep all systems working properly for as long as possible, it is better not to miss the MOT at the dealer.

TO-1: list of works and something else

A car is quite a complex device by its design. A large number of components and assemblies, rubbing surfaces - all this gradually wears out. In the event of any design deviation, such a defect can only be determined by a professional check at the dealer using modern equipment. We can say that any trip by car, even a short one, leads to a deterioration in his condition. Therefore, the machine must be serviced in time and replaced with defective or defective parts and assemblies.

The TO-1 work list is as follows:

fastening work (tightening car threaded fasteners);
performance of lubrication works;
control;
diagnostics;
cleaning and adjustment.

Each of the above points in this article we will consider in more detail. I would like to note that TO-1 is extremely important. Indeed, during this period, random malfunctions are checked and eliminated, which lead to a reduction in engine life, a decrease in comfort or increased fuel consumption. also in without fail the operation of the catalytic converter is checked or particulate filter, which are responsible for the neutralization of harmful chemical compounds falling into environment with exhaust gases.

As practice shows, most motorists do not follow the recommendations for the inspection and maintenance of the vehicle before each trip. However, it is highly recommended to check the following systems:

performance electrical appliances center console;
brake fluid level;
engine oil level;
carry out an inspection of the body of the car;
adjust the rear-view mirrors;
check steering.

In fact, doing the work from the above list is quite simple. It will take literally a few minutes. However, daily maintenance (EO) is desirable as it can save the driver's life. For example, at the next maintenance, you find that there is no brake fluid. This indicates that the system is leaking and there is a leak somewhere. If you do not give due attention to this, then at the next traffic light you may not stop on time. This also applies to mirrors, the position of which can randomly go astray. And while driving, it is simply dangerous to adjust them, because the driver will be distracted from the road, which can lead to an accident.

Regular car wash

In fact, this is a personal matter for each driver. However, there are certain recommendations for car interior care. After all, breathing the dust that got into the cabin while driving is not very useful. Therefore, the manufacturer strongly recommends regular maintenance of the interior of your car. This is necessary not only for the aesthetic component, but also to keep the plastic and seat upholstery clean. After all, if you do not clean the interior for a long time, then over time, dust and dirt eat into the fabric, and dry cleaning of the interior will be required, and this is not a cheap procedure.

It is also advisable to regularly wash the body of the car. After all, it is almost impossible to perform a high-quality check of a heavily contaminated body. In addition, deposits or dirt that remain on the surface for a long time paintwork vehicle, eat into the paint and can damage it. It is desirable to remove strong pollution with the help of Karcher at a car wash. Improper self-washing of the car can lead to scratches on the car's paintwork.

About the frequency of maintenance

Usually, the regularity of carrying out certain works is determined by the manufacturer. The data is indicated in service book, where it is written - when to perform certain work. But it is worth noting that the frequency is determined by several factors. First, the time interval. For example, the alternator belt needs to be changed every 2 years (24 months). Secondly, time and mileage. The oil is changed every year (12 months) or every 15,000 kilometers, whichever comes first. Thirdly, mileage. bright volume an example is a belt replacement or which is performed every 100-150 thousand kilometers.

Therefore, as you understand, even if you practically do not drive a car, it will have to be serviced. For example, you set new belt generator and in two years drove only a few thousand kilometers. In fact, the belt is completely new, but since this product does not change from mileage, but from the expiration date, it must be replaced. Over time, the rubber cracks and becomes less elastic, which most often leads to a break. But the timing belt, which is also made of rubber, changes after a certain mileage. Therefore, one such belt can stand on a car for 5 or 10 years, and nothing will happen to it.

TO-1: work order

The first maintenance of the car is indicated in the service book. Usually TO-1 is performed with the onset of 15 thousand mileage. Although, depending on the brand of car, the data may vary slightly. Usually, dealers do not follow a specific order of work, but simply check, adjust, lubricate and service the following vehicle components:

MOT in detail

Well, now let's look at a few of the most interesting points in more detail. Let's take adjustment work as an example, as they look the most interesting. Usually, dealers practically do not fulfill them, although the price tag is set to the maximum in the price list. For example, checking the fastening of the generator. Usually, the need to perform such a procedure arises only with the repair of this node. After all, the manufacturer carefully fixed and adjusted everything. Another thing is that wheel alignment may be needed, because you are only running in your engine and chassis, which has not yet been under load.

But work such as adjusting a car's carburetor or injection system, often not required, but unscrupulous employees dealer centers it is still performed. Although these items are indicated by the manufacturer, it is therefore necessary to inspect them, preferably in your presence. Then you can independently inspect the status of a particular node. If there is a factory defect of parts, assemblies or assemblies, then the driver will notice it almost from the first kilometers of car operation. If the air conditioner does not work or does not work well, it can be seen immediately. If there is a running gear extraneous sounds, then everything is clear here too. But many works are carried out to extract money from the driver, which is why many motorists refuse to carry out technical work and repair their vehicle on their own or at budget service stations.

How much does the first MOT cost?

It is extremely difficult to give a definite answer to this question. There are several factors that affect the pricing of TO-1. Firstly, the condition of the car after the same 15,000 kilometers. All drivers are different, and some understand that during the break-in of the internal combustion engine, give too much high revs can't and others can't. This leads to the fact that some pay 10,000 rubles for maintenance, while others pay 30,000, and then they are indignant. Secondly, a lot depends on the dealer. There are more conscientious specialists, and there are less. If you are a little versed in the design and construction of a car, then it is better to be present at the MOT and breathe into the back of the head of the inspector. After all, it is not known how much it will cost to adjust the clutch drive if you are not around.

Therefore, as you understand, pricing is dictated by dealers and it is rather difficult to do anything about it. It is quite another matter that dealers often give out factory defects for improper operation. Accordingly, the part has to be bought by the driver. Proving something is difficult, but with due effort it is quite possible. TO-1 for Hyundai Getz costs an average of 10,000 rubles. But servicing a premium car will not be cheaper than 30-40 thousand or more.

A few important details

It is necessary to understand that there is different kinds and frequency of maintenance. For example, there is also TO-2, which is practically no different from the first. On the second maintenance, the amount of work is somewhat larger. Adjusting and lubrication work performed with the removal of some components and assemblies. To check the correct operation of the systems, use special equipment. For example, checking the muffler and catalytic converter, as well as lambda, is performed using an oscilloscope, which shows the correct operation of the sensors.

Based on this, we can say that TO-2 will cost more than the first. However, if you do not pass it, you will again lose the warranty on the vehicle. Therefore, do not forget about the implementation of TO-1 and TO-2, which are necessary not so much to ensure safety, although this is also important, but to stay on warranty service. As practice shows, while there is a guarantee for the car, it rarely breaks down. The most interesting begins after the expiration date. Perhaps this is due to the quality of our roads or fuel. But always all the worries about repairs fall on the shoulders of the driver.

There are also seasonal service(CO). Especially this species technical work is relevant for residents of the northern part of Russia. However, for the central part of the CO is mandatory procedure. Here it makes sense to talk about the expediency of performing these works. After all, according to statistics, a large number of The accident occurs right at the start winter season when many motorists have not yet changed their shoes. Usually SO works are carried out twice a year: in the end of autumn and in the middle of spring.

Summing up

So we reviewed with you the list of works TO-1 and many others interesting moments. In addition to TO-1 and TO-2, do not forget about seasonal and daily maintenance. Each driver must check the fluid levels in the lubrication, cooling and brake systems before driving. It is clear that the brakes play a huge role, but also the cooling system or engine lubrication is entirely responsible for good work power unit. If you do not perform maintenance of the vehicle, and through your fault, any serious damage, then you will have to restore the car at your own expense.

In general, maintenance is once a year or every 15 thousand km. must be performed. Unfortunately, Russia has not formed the most best opinion about dealership. Often unscrupulous employees wind up price tags, which leads to large financial costs. In Europe, the prices for scheduled maintenance are somewhat lower. This is despite the fact that only the necessary adjustment and lubrication work is performed there. Also, they are much more likely to make cars under warranty, although this is required in European countries less often than in Russia.

Maintenance TO-1 is designed to maintain the vehicle's performance. It is carried out after the operation of the vehicle on the line and contains control and diagnostic, fixing, adjusting, lubricating and other works aimed at identifying faults, reducing the intensity of changes in technical condition parameters, ensuring fuel economy, operating materials, reducing the harmful effects on the environment.
