Installation and maintenance of trucks. Tips from the experts

03/15/2018

The specifics of the operation of trucks determines some features of their design. This applies not only to technological solutions used in the design process, but also to the care of trucks. In the material of the article, we will briefly consider some features of the device and maintenance of a truck.

Key structural differences between trucks and cars

Most of the trucks are engaged in cargo transportation. This process implies delivery time limits. At the same time, as a rule, it is impossible to break deadlines in any case. For example, food products have their own limited shelf life, exceeding which will lead to damage to the goods and losses.

Therefore, the primary task in the design of a truck is to achieve maximum reliability while maintaining maintainability and low price. Obeying the rules dictated by the specifics of work, the arrangement and maintenance of trucks has certain differences from passenger cars. Consider the main design features inherent in almost all trucks: nine0003

  1. Body frame. In passenger cars, almost all bodies are load-bearing. Trucks can't afford it. The weight of the transported goods is incompatible with the concept of a load-bearing body due to the low rigidity and, in general, the low strength of this technical solution. Therefore, the vast majority of trucks are built on rigid frames.
  2. Pivot Suspension . Ball joints in a multi-link suspension or MacPherson strut design allow the car to be softer and more controllable. nine0004 In conditions of high axle loads, kingpins are more reliable and durable.

    In addition, the pivot connection is cheaper and often allows maintenance of this assembly, which is almost always excluded in ball bearings.
  3. Springs instead of springs. Leaf suspension is stiffer than spring suspension, but at the same time more reliable. Also, the springs are able to withstand greater loads.
  4. Reliable derated diesel engines with high torque and impressive displacement. For trucks, it is not the engine power that is important, but the presence of a large torque, preferably shifted towards low revs. This allows trucks to move off without problems and overcome steep slopes.

These and some other features impose their limitations on the operation and maintenance of trucks.

Features of the device and maintenance of the truck

Some aspects of maintenance are closely related to the specifics of the truck design. Unprepared motorists who have moved from cars to trucks do not immediately delve into all the nuances of maintenance.

At first glance, almost everything in the device and maintenance of trucks is the same or very similar to passenger cars. There are regulations for EO, ​​TO-1, TO-2 and so on. Indeed, the main maintenance items do not differ from those for passenger cars. But there are still some key differences. nine0003

Let's take a quick look at the important points when carrying out truck maintenance, which are not always given enough attention:

  1. Mandatory check of the frame and body connections. Large masses transported by trucks create serious loads on the frame. And it is not uncommon for cases when important load-bearing elements break off along the route.
  2. Lubrication of springs, injection of kingpins, universal joints and other moving parts equipped with oilers. You should definitely familiarize yourself with the truck lubrication map and do not forget to lubricate all moving parts. nine0016
  3. A thorough check of not only the brake pads, but also the lines, working cylinders, the fluid level in the tank (for the hydraulic system), the performance of the brake valve and the integrity of the receivers (for the pneumatic system). A loaded car with problems in the braking system is the most dangerous road user.

In connection with all the features discussed, trucks usually receive more attention during maintenance than cars. The most important aspect of the trouble-free operation of a truck is the use of quality parts and materials in the process of repair and maintenance. TopDetal.ru, an online truck spare parts store, sells high-quality components for trucks of domestic and foreign production. In our catalog you will find a wide range of spare parts, and if the required part is not in stock, we are always ready to bring it to order! Specify information by phone 8 800 444-75-16. nine0003

Maintenance of trucks: frequency, scope of work and general recommendations

Every truck requires periodic maintenance. This is a series of procedures, the purpose of which is to ensure the stable operation and high quality of all elements of the vehicle. Regular maintenance is especially necessary for trucks, which are constantly subjected to significant loads. The lack of timely inspection and repair is the main reason for the decline in truck performance. This important event allows you to effectively use the machine, reduce the cost of its operation and repair. nine0003

Maintenance of trucks, in comparison with other types of vehicles, has its own characteristics, which every owner should be familiar with. The make, model and manufacturer of the car is not important - maintenance is equally necessary for both domestic and foreign trucks. Below we will talk about the stages and features of maintenance without reference to the type and model of the vehicle.

Maintenance schedule for trucks

Many car owners do not realize that timing and other aspects of vehicle maintenance do not depend on manufacturers and suppliers. These rules are determined by the regulations of the state standard GOST 21624-81, which is called the “System for the maintenance and repair of automotive equipment. Requirements for operational manufacturability and maintainability of products. This document establishes the timing and frequency of maintenance, contains a list of rules and requirements for the production and repair of automotive equipment. nine0003

It is worth noting that car manufacturers also set their own maintenance intervals and procedures. However, observations show that the state standard optimally reflects the current state of affairs, and the timing and maintenance rules regulated by it are in many respects similar to the requirements of manufacturers.

Frequency of scheduled maintenance

State standard describes three types of vehicle maintenance:

  • EO - daily maintenance;
  • TO -1 - primary maintenance;
  • TO -2 - repeated (second) maintenance.

GOST also contains requirements for the frequency of scheduled maintenance (service interval). It depends on the mileage of the truck and is measured in kilometers traveled. Various types of maintenance are required at the following stages of operation:

  • Daily maintenance, as the name implies, must be carried out once a day; nine0016
  • The first MOT is carried out after 4000 kilometers traveled;
  • The second maintenance takes place when the truck has traveled 16,000 kilometers.

GOST does not specify the terms of maintenance, which should be carried out during the vehicle's running-in. These requirements are set by the manufacturer. In most cases, the break-in of trucks is about 1000 kilometers. Many manufacturers recommend replacing engine and transmission oil when this value is reached. Despite the fact that the first maintenance should be performed with a mileage of 4000 kilometers or more, the procedure can be carried out earlier if the car owner is not sure that the established operating rules are fully observed. This will help preserve the resource of the engine and transmission, the reduction of which leads to significant problems and financial costs during the subsequent use of the vehicle. For greater certainty, it is recommended to carry out part of the maintenance work at a mileage of 1000 to 1500 kilometers. nine0003

GOST does not specify another type of maintenance that takes place on the territory of Russia - seasonal maintenance (SRT). It is performed every six months in early spring and late summer. The purpose of this procedure is to prepare the vehicle for upcoming climate changes associated with the change of season.

There are exceptions to the general requirements. For example, most modern models of freight transport from European and American manufacturers, including Iveco brand cars common in the Russian Federation, are characterized by an extended service interval. It can reach 60,000 kilometers. We are talking about the second maintenance (TO-2), which involves the replacement of engine oil. This fact does not contradict the rules of the state standard, since the mileage regulated by it between TO-2 has no upper limit (only the minimum period is indicated). nine0003

Large trucks and long-haul tractors have a service interval of up to 100,000 kilometers. But it is worth considering that this value is set only for the operation of transport in European countries. In Russia, there are many negative factors that accelerate the wear of the engine and other mechanisms of the car, including poor fuel quality and unacceptable road conditions. If European standards are followed for the transport described above, then there is a possibility that the truck will fail before it reaches the next maintenance or require significant repair costs. nine0003

So, what is the best interval to perform maintenance on a truck? The answer to this question lies in many factors, but in most cases it depends on age. If the vehicle was purchased recently and is still within the warranty period, then the procedure must be carried out according to the requirements of the dealer. For cars that have been in operation for a long period, the service interval is determined by the owners themselves. In this case, it is recommended to follow the terms specified by the manufacturer or GOST recommendations. nine0003

Approximate scope of work for EO, ​​TO-1, TO-2 and STO

The list of procedures included in the maintenance depends on the vehicle mileage:

  • Daily maintenance. During the EO, the vehicle is inspected for the presence of external defects in individual elements, the performance of the braking system, the integrity of lighting devices and other mechanisms are tested, and tire pressure is determined. Daily maintenance involves washing the car and refueling it if necessary. In other words, the purpose of the SW is to ensure that the freight transport is operational for the current trip. nine0016
  • First maintenance. TO-1 includes checking the level of engine and transmission oil, antifreeze and other fluids in the system. There is an adjustment of various mechanisms of the car - steering, clutch, pedal free play. During the first maintenance, the main components and assemblies are lubricated. Lubrication work is carried out in accordance with the card, which must be kept by the owner of the car or in the service of an official supplier or manufacturer. nine0016
  • Second maintenance. At TO-2, procedures similar to the previous paragraph and a number of additional measures are performed. First, the engine oil is changed. Often, it is during the second maintenance that some important components are disassembled and repaired, which were only checked and lubricated during TO-1. In most cases, the service interval specified for a particular truck is similar to the period between the second MOT. nine0016
  • Seasonal maintenance. The list of works included in the service station depends on the season of the procedure. At the beginning of autumn, the truck is prepared for operation in the winter. To do this, antifreeze is poured into the cooling system, and antifreeze liquid is poured into the washer reservoir. In some cases, the engine oil is replaced with a similar one, but with a lower viscosity index. It is mandatory to check and adjust the density of the electrolyte batteries. Before the onset of frost, condensate must be removed from the receivers of the pneumatic system and the dryers must be replaced. At negative temperatures, it is recommended to drain the condensate 1-2 times a week. At the beginning of spring, the list of work on service stations is noticeably smaller, since the requirements for operating conditions in the warm season are lower, and most trucks are perfectly adapted to them. nine0016

During the year, the owner of the truck undergoes several types of maintenance.
