What are the maintenance items for large trucks? Be detailed. Please have an experienced teacher for

1. The so-called car maintenance refers to maintaining and restoring the technical performance of the car to ensure that the car has good usability and reliability. Timely and correct maintenance will extend the service life of the car, improve the safety performance, save money and save many troubles of repairing the car. 2. The car maintenance we usually talk about is mainly from the work of maintaining a good technical condition of the car and prolonging the service life of the car.

To sum up, there are three main aspects: Body maintenance. Car body maintenance is also commonly known as car beauty.

The main purpose is to remove all kinds of oxidation and corrosion outside and inside the car, and then protect them to highlight the "beauty" of the car as much as possible. It mainly includes: car paint maintenance, cushion carpet maintenance, bumper, skirt maintenance, instrument panel maintenance, electroplating processing maintenance, leather and plastic maintenance, tire, wheel maintenance, windshield maintenance, chassis maintenance, engine appearance maintenance, etc.

In-car maintenance. The purpose of car body maintenance is to keep the car forever young, and the purpose of car maintenance is to let the car travel hundreds of thousands of kilometers without overhaul and ensure that the car is in the best technical state. It mainly includes:

The maintenance of lubrication system, fuel system, cooling system, brake system, carburetor (fuel injector) is commonly known as changing three filters. Refurbished body. Such as the diagnosis and treatment of deep scratches, the repair of multi-material bumpers, the repair of hard injuries of wheel hubs (covers), the refurbishment of leather and chemical fiber materials, and the refurbishment of engine colors.

3. According to the maintenance period, car maintenance is divided into two categories: regular maintenance and unscheduled maintenance. 1) Regular maintenance includes: daily maintenance, first-level maintenance, second-level maintenance; Purpose of regular maintenance:

A car is made up of tens of thousands of parts. With use, the performance of functional components, including lubricating oils, gradually decreases due to wear, aging, corrosion, and other factors. Under normal vehicle driving, this change gradually occurs in many parts.

Because no car is used exactly the same, it is impossible to predict that every part will wear and age the same. For this reason, the factory prescribes a certain inspection interval to adjust and replace components that can be expected to change over time or with use, which is called "regular maintenance". The aim is to restore the vehicle's performance to its best condition, to prevent small problems from becoming major problems, to ensure the safety of the vehicle, as well as to achieve optimal economy and a long service life.

The basic items of car maintenance mainly include changing the engine oil and oil filter element.

Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting or replacing certain parts of the relevant parts of the car, also known as car maintenance. Modern car maintenance mainly includes the maintenance scope of engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

Some people worry about doing maintenance for the car every day, doing too much for fear of being pitted, spending more money in vain, and doing less for fear of not being good for the car, and even having potential safety hazards. All parts on the car that need to be maintained or regularly replaced, and the replacement cycle does not exceed 100,000 kilometers. Today we will talk about all the maintenance items to be done within 100,000 kilometers and the number of kilometers.

Based on the average mileage of most family cars, it can travel about 10,000 kilometers per year, and it takes a little more than 6 and a half years to travel 100,000 kilometers. The first is the most basic oil and the replacement of various filter elements, if the original oil or the same grade as the original oil, then according to the manufacturer's recommended kilometers of maintenance, most of the car is 5000 kilometers maintenance once, some cars are 7500 kilometers, some are 10,000 kilometers. Every time you change the oil, you have to change the oil filter, and the air filter and gasoline filter are also replaced on time according to the manufacturer's recommendations.

If you maintain 5,000 kilometers once, you need to change the engine oil 20 times to 100,000 kilometers, and you need to change the engine oil 10 times if you maintain it once for 10,000 kilometers. There is also an air conditioning filter, which is generally changed once every six months, and if you use less, you change it once a year, and replace it every summer.

When the kilometers reach 2-30,000 kilometers, it is necessary to do four-wheel rotation and cleaning the throttle oil circuit, and this project can be replaced according to the number of kilometers. Let's say you do it once at 30,000 kilometers, and you need to do it three times at 100,000 kilometers. The spark plug should be replaced once for 4-50,000 kilometers, and if the original car is not an ordinary spark plug, then replace it again after about 80,000 kilometers.

There are many brake pads that need to be replaced, there are quite a lot of vehicle brake pads life in about 40,000 kilometers, according to the frequency of the owner stepping on the brakes, some 80,000 kilometers do not need to be replaced, and some are less than 40,000 kilometers to be replaced.

Next, 60,000 kilometers will be required to do a comprehensive maintenance, replace the whole car oil, replace the timing belt, and replace the battery. These projects should look at both the number of kilometers and the service life, and they must be changed when they are 60,000 kilometers, because when the kilometers are up, the time has actually been exceeded. So if the number of kilometers traveled is relatively small, you can do it a little earlier, and you can do it for 10,000 kilometers.

As for the battery, it should be checked and then confirmed whether it is replaced, because the life of the car is very different due to different car habits, but many cars will be replaced in 3-4 years. Next, the tires need to be replaced at 80,000 kilometers, even if the wear is very slight, because it takes more than 5 years to drive 80,000 kilometers, and the tires must be replaced in 5 years.

The basic maintenance items of large trucks are: 1. Change the engine oil and three filter oil filter elements. Air cleaner.

Diesel filters. 2. Wheel maintenance, due to the large load capacity of large trucks, their bearings are tapered bearings, which need to be added with high-grade butter. 3. Transmission oil change, large truck transmission due to overload and heavy load, transmission wear is large, in order to reduce wear and tear to change gear oil regularly.

4. The rear axle tooth pack is similar to the transmission, basically the oil is changed twice, and the tooth pack gear oil must be changed once.

Change the oil, oil filter, gasoline filter, air filter. Usually change the car oil once every 5000km, and change the gasoline filter once every 20000km. [Truck shop parts platform].

Check whether the position of the liquid level of the automobile coolant is in accordance with the regulations. Usually the refrigerant needs to be replaced every two years.

Check the position of the brake and clutch fluid level. Brakes and clutch fluids are usually replaced every 30,000 km or two years.

Check whether the oil level of the steering power tank meets the regulations, and check whether there is oil leakage at the interface of each oil pipe of the system.

Check the liquid level of the battery and the liquid level of the glass cleaning agent tank, if the liquid level is too low or insufficient, it needs to be added or replaced in time.
