Zhao Ke and Lao Huang glanced at each other, when Zhou Jingming tested the car, he really only checked the water tank of the first car, since he was so sure that the water temperature of the second car was too high, then he only needed to check the water tank to know whether what Zhou Jingming said was right.

At least there is a lot of mud and dust on the tank, which is still obvious and can be seen at a glance.

Zhao Ke nodded at Lao Huang, and then Lao Huang turned around and shouted at one of the workers, "Xiao Chen, you go and check the water tank." ”

"Master Huang, don't you even believe us? You were there when the car was repaired. Besides, not long after the car was bought, where did the mud and dust come from the water tank?" the worker was clearly not happy.

However, Zhou Jingming can also understand, looking at the oil stains on several of their bodies, you can see that it is definitely hard and hard when repairing the car, and he vetoed their hard work in a few words, and he is probably not happy if he is himself.

Lao Huang's eyes widened, "I don't believe you, let you go to see you, nonsense!"

Although Zhou Jingming has just come on the first day, Lao Huang is actually more inclined to believe in him in his heart, this feeling is really amazing.

It can be seen that Lao Huang's prestige in the maintenance team is still very high, and when he stared at him like this, the person immediately shrank his head, and then muttered in a low voice, walked to the car, and opened the car cover.

"What's the matter, is what Xiao Zhou said true?" Zhao Ke asked.

The worker didn't answer, his eyes were round, his face was full of incredulity, and his mouth was full of words, "Impossible, it's obviously a car I just bought, where did it come from so mud and dust?"

Lao Huang was anxious, so he simply walked to the front of the car quickly, and slapped the person on the head, "You kid, are you deaf?

Subsequently, Zhao Ke and Zhou Jingming also came to the front of the car, and looked inside, there was indeed a lot of dust and mud on the top of the water tank, and there was also a lot of cotton wool distributed, which covered it, and the heat dissipation capacity of the water tank naturally decreased.

"Xiao Zhou, how do you know?" Zhao Ke asked intently as he stared at the water tank tightly.

"This is common sense, and veteran drivers who have driven a car should know. And the car should be a private car, often driving on dirt roads in the countryside, it is normal to have mud. Of course, this is only a superficial reason, whether there is scale deposition inside the engine, this still needs to be disassembled to know. ”

Zhou Jingming explained behind his back.

Common sense?

Zhao Ke and Lao Huang smiled bitterly again, what a common sense!

"It's really a god! How do you know it's a private car?" Xiao Chen, the worker who was still very stubborn just now, felt like a dream at the moment, when this car was delivered, it was he who received it, and the natural way was whether it was a private car or an official car.

In the 80s, Shencheng cars were mainly used for official cars, and although there were few private cars, there were also them.

When the other workers heard this, they couldn't help but come over and began to talk in whispers one by one.

"Maybe it's a guess. ”

"That's right. The tank is easy to see, but what about the clutch and friction plates, how can you conclude that there is a problem?"

There are still a few people who say this, but it is obvious that their tone has also become uncertain, from the initial very firm rebuttal, to now it is only a tentative question, for Zhou Jingming, this is progress.

"Xiao Zhou, tell me what you think!" Zhao Ke didn't care about those people's discussions, but turned to look at Zhou Jingming, it can be said that Zhou Jingming had proven himself just now.

No wonder Mr. Su has such a high evaluation of him, it seems that the teacher's vision of people is still much better than his own!

"The first car idling shake, probably because of too much carbon in the engine, this is mainly because the car is relatively long, belongs to the case, if not properly handled, it is easy to cause the car to break down, as for the main reason for the frequent breakdown of these cars, I am not sure, I need to further disassemble the car to know. ”

Zhou Jingming didn't jump to a conclusion right now, and he still needs to look further.

"I just heard Xiao Zhou say that when the two cars are driving, there will be clutch slippage and scorched friction plates, does that mean it is related to the gearbox of the car?" Lao Huang couldn't help but say. The problems pointed out by Zhou Jingming coincide with his initial inference.

"I think so too, although I don't know what the situation is with other cars, but I speculate that these cars from the factory, more or less will have the problem of scorched friction plates, but those owners did not notice such a smell, over time, the friction plates are seriously damaged, and the gearbox will fail, resulting in breakdown. Zhou Jingming analyzed.

The entire transmission system of the car is basically integrated into the gearbox, and if there is a problem with the gearbox, it is strange that the car does not fail.

"Then is the next step to disassemble the gearbox of the car?" Zhao Ke was full of energy, as if he saw the dawn of problem solving.

"Yes! The gearboxes of these problematic cars need to be disassembled, and I need an original gearbox that is not assembled as a comparison! I need to figure out whether it is a design problem, or a component problem, or both. "Once Zhou Jingming entered the working state, he completely changed as a person.

"First of all, the gearboxes of these two cars are disassembled, and of course, the engine of the first car should also be checked to see if there is too much carbon deposit. ”

Zhou Jingming habitually gave orders. But after saying these words, he was a little embarrassed and stunned, because he seemed to have forgotten his identity, Zhao Ke and Lao Huang who were present, no matter who they were, were more qualified than him to say so.

But Zhao Ke didn't realize this, as if Zhou Jingming was the leader of this matter, and he was just a follower, "Why are you stunned, didn't you hear what Xiao Zhou said?"

Dismantle!

Just do it. Under the command of Lao Huang, several workers in the maintenance team immediately got busy, whether it was dismantling the engine or dismantling the gearbox, it was a huge project, and these two assemblies could be said to be the most complex parts of the car.

Today, not only to disassemble the engine and gearbox at the same time, but also to disassemble the gearbox of the remaining dozen cars, these workers will inevitably have some resentment.

It's best that the engine and gearbox of the first car don't have the problems he said, so that not only does the rear one not have to be disassembled, but it can also slap him in the face once!

Soon, the engine of the first car was removed, and several workers opened it and were immediately dumbfounded, and it was really like what Zhou Jingming said, there was really a lot of carbon deposits in it!

This kid is so evil?

Several people looked at Zhou Jingming with different eyes, but they still didn't give up, and after the gearbox was also removed, everyone surrounded him again.

After the box was opened, a pungent smell of burnt smell immediately came out, and then looked at the friction plate inside, which was exposed on the surface outside, and a section of the charred area could be clearly seen.

That's right again!

Everyone present looked at Zhou Jingming without exception, some admired, some admired, and of course, more surprised!
