The truck driver was stunned for a moment, and quickly said, "Ah, that's it." Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 Info: The tire patterns on both sides of me are really different. …… , little master, is this the reason?"

Meng Wentian shook his head and said: "There is this kind of influence, but it is very small, if you drive and find that it deviates, it may be this reason, because you have been driving this car for a long time and are very familiar with its performance, this little difference is indeed possible for you to find." …… However, just now Liu Gong went up and drove the car for a while and found that it had a deviation problem, indicating that the phenomenon of deviation is more serious, and this problem will not be caused by the difference in the tread of the two tires, at least not entirely because of them, there must be other reasons. ”

The driver nodded approvingly, feeling like he had learned a lot.

Rounding the rear of the car, they came to the rear wheel on the right side of the car.

Meng Wentian observed the tire for a few seconds, then looked up at Zeng Ninghai and asked, "What is the difference between you standing here?...... Did you find anything?"

Looking at the tires stained with mud, Zeng Ninghai and the others and the driver all shook their heads blankly.

Guo Qiulan, who had been following Meng Wentian closely, glanced at Meng Wentian and said uncertainly: "It seems to be ...... It seems to be hotter here. The temperature of the tire on the left doesn't seem to be as high as it is here. ”

Because the tires are constantly rolling on the ground, there is rolling friction with the ground, resulting in high temperatures of the tires. This is the reason why when a truck has just stopped, if someone stands next to the tires, they will not only smell a pungent smell of rubber, but also feel the heat rolling in.

Zeng Ninghai looked up at the sun and said, "It's a little hot, but it's because the sun is shining, and the tires over there are covered by the sun." ”

But his words were quickly rejected by Liu Wenbo: "It's winter, how hot is the solar energy that just came out in the morning? ”

Everyone's eyes looked at Meng Wentian.

Meng Wentian didn't immediately draw conclusions to them, but took them to continue to the tires in front.

After looking at the front tires and looking at the front of the car, he led everyone back to the right rear tire, which felt a little unusually hot just now. "Generally speaking, in addition to the problem of the steering machine, there is a problem with the moving parts on the right, and there is a high possibility that there is a problem with the right tire," he said. This tire is located on the right, and the temperature of the wheel is higher than normal, so when judging the fault, we can temporarily assume that this is the fault point of the truck's mistracking. ”

Meng Wentian talked eloquently, and nodded again and again to a few workers who did not have much repair experience, even the truck driver was also happy, and recognized that Meng Wentian was a maintenance master, and also believed that the fault was here.

He sighed: "It's still your little master who has the ability, and he can see the problem at once." I asked them for a long time at the Hongshan Auto Repair Factory, and they didn't dare to say, they only said that they wanted to see it. …… Master, how much does it cost to fix it?"

Although he admires Meng Wentian, the truck driver doesn't want to pay more.

Meng Wentian raised his right hand, stretched out four fingers, shook it, and asked, "How is it?"

"Ah, four hundred, that's too much!" the truck driver was shocked and hurriedly shook his hand, "It's too expensive, it's too expensive, no wonder some people say that you slaughtered people, yesterday you slaughtered 250,000 yuan for a car, right?"

"Two hundred and fifty thousand? hehe, three hundred thousand. Meng Wentian smiled and said, "Master, I'm talking about forty yuan." If this kind of truck costs four hundred, it can be called an overhaul. ”

"Forty ...... Only forty?" the driver was shocked, looked at Meng Wentian in disbelief, and then looked at the others.

Other workers were not surprised that Meng Wentian offered a low price, after all, it is now a big reward before the Spring Festival, and this car is the first car to come to the big reward activity, it is right to give some discounts, they are surprised that Meng Wentian opened the price so early, and the fault has not yet been determined, in case there are broken parts or something, what can you do with forty yuan?

Meng Wentian said to the driver: "It's just to take off a few nuts and inject some butter, it's very simple, and it won't take much time." If you don't do it yourself, I'll guide you and pay 30 yuan for materials. If you encounter this kind of problem in the future, solve it yourself. ”

Several workers were even more shocked and couldn't help but look at Guo Qiulan.

Guo Qiulan glanced at Meng Wentian and nodded.

The driver was overjoyed and hurriedly said, "Okay, good, thank you." Please teach me how to ......"

Meng Wentian said to the driver: "The preload of your hub is too tight, which causes too much friction inside the hub bearing, which increases the temperature of the hub and evaporates the lubricating butter inside." Without butter, the friction is greater, and the temperature of the hub is higher, which further accelerates the evaporation of butter and forms a vicious circle. …… It is precisely because of their internal friction that the tires have high resistance and cannot run, resulting in deviation and steering wheel throwing. ”

The driver nodded as if he didn't understand, while Liu Wenbo and the others quickly understood the cause and effect, and looked at Meng Wentian gratefully. They felt that Meng Wentian was a selfless teacher from the bottom of his heart, silently helping them. The only thing I don't understand is why Meng Wentian still told the driver: You taught the driver the car repair technique, will people come to the repair shop to repair the car in the future?

Once you find the crux of the problem, it will be easier to solve the problem.

Under the guidance of Meng Wentian, the driver quickly removed the hub nut with a large socket wrench, and quickly filled it with lubricating butter, and then installed and restored, and Meng Wentian carefully adjusted the nut torque.

In addition to handling the right rear wheel, he persuaded the driver to accept the four-wheel precise positioning.

It only cost 30 yuan, not only to solve the problem, but also to eliminate the hidden danger of poor four-wheel alignment, and even get a big gift, the driver was very satisfied and drove away.

Before leaving, the driver praised their good service attitude and high technical level, and said that they must tell their relatives and friends after going back, so that they can come here for vehicle maintenance and repair.

Looking at the back of the truck leaving, Guo Qiulan smiled and asked, "Aren't you short of money, why do you open such a low price?"

Meng Wentian smiled: "It varies from person to person. He doesn't have any money, so he's only good for us to advertise. If he shouts high, he will scold his mother, and I can't charge a few more dollars, so it's better to slaughter a little more when I meet a rich person. Slaughtering a rich person can be worth dozens or hundreds of ordinary car owners. ”

Guo Qiulan glanced at him and asked teasingly, "Are you reminiscing about yesterday's good things again?...... "Huh, what's the sound?"

Meng Wentian's face changed: "It's not good! I'm going to check it out...... Go to the office building and go up to the second floor! Call the police immediately!"

Seeing Meng Wentian's solemn look, Guo Qiulan and the others were stupid, and they didn't know what to do for a while, and looked at the door.

Meng Wentian said angrily: "Hurry up! What are you doing?"

Zeng Ninghai stammered and asked, "I'll ...... with you."

Meng Wentian rushed towards the gate, and at the same time said loudly: "You protect the boss and don't let them rush upstairs!"

Guo Qiulan seemed to have recovered from the shock, and while following Meng Wentian to the gate, she instructed Liu Wenbo and them: "If you don't know how to fight, go upstairs immediately, and I will deal with them with Meng Wentian." ”

Meng Wentian turned his head to Guo Qiulan and said angrily: "Don't mess around!"

Guo Qiulan was stunned for a moment, and immediately said: "I am a judo blue belt ......"

Meng Wentian really didn't understand the division of judo levels, so he couldn't help asking, "Is the blue belt powerful?"

Guo Qiulan said proudly: "Nonsense! There is no problem in beating three men." …… And, of course, not as powerful as you. ”

Hearing that he could beat three men, Meng Wentian was relieved: at least he had no problem protecting himself.

But when he rushed out of the gate, he saw a group of nearly twenty thugs getting out of the two vans, one by one with sticks and sticks, as if to let the people around him know that they were gangsters, and knocked and smashed all the way, even the garbage cans on the side of the road were kicked to the ground and smashed a few more sticks.

Meng Wentian was very glad that Uncle Wang was not on duty at the door, otherwise he would probably be beaten indiscriminately by these thugs.
