Rebirth of the Auto Giant

In the eyes of younger brother Zheng Jin and younger sister Zheng Hong, the eldest brother Zheng Qiang has now "escaped poverty" and gone straight to a well-off society. He does not have to get up early every day to go to school and does not have to sit boredly in the classroom and listen to the teacher's lectures.

The hardest thing in life is to be a student, getting up earlier than the chickens and not having a penny in your pocket.

The younger brothers and sisters are extremely envious of their elder brother.

It's a pity that I am a minor now, otherwise I would have asked my eldest brother to talk to Mr. Wang, and I would have gone to work at the Tang Dynasty Production Base to escape the sea of ​​misery.

The younger sister would occasionally "advance" one or two cents from Zheng Qiang. Although the eldest brother's socks were smelly, he was still getting a salary, which was much better than the second brother Zheng Jin.

A coal mine in a province in Shandong.

This enterprise unit first bought a ZL50 loader of a certain brand. It was equipped with a Tangchao Dynamics TCD6114ZGB six-cylinder diesel turbocharged engine. It has been in the car for more than 5,000 hours and the three-warranty period has long been issued.

.

The working environment in coal mines is harsh and if maintenance is not carried out in time, especially if the air filter is not maintained in time, engine wear will be particularly serious.

This is what Guo Yuquan and others told the customer when they came to do the 100-hour first maintenance.

Because it is a new car, the performance is not obvious for the time being, and no one pays much attention to it. It takes at least three or four months for an air filter to be replaced, and the engine oil is only changed every 400 hours.

In their eyes, manufacturers say this mainly because they want to make more money selling their own maintenance parts.

After driving the car for a year, the car's lack of power gradually became apparent, and the color of the exhaust was different from before. It used to be off-white, but now it is dark blue, and the amount was greater than before and the smell of engine oil was stronger.

I found a few guerrilla workers to check it out, and they said it was burning engine oil. It was most likely caused by excessive wear on the cylinder liner and piston inside. Of course, it was not ruled out that it was caused by a problem with the valve oil seal. However, considering the power of the engine,

The piston is most likely to be disassembled and overhauled.

In line with the concept of saving energy and using it day by day, I didn't listen to the master's words.

After another month, it seems that it can't be repaired today. The oil in the engine oil pan has increased for no reason, and it seems that there is water in it.

"What's going on?" the logistics supervisor asked when he saw the unexplained increase in engine oil.

Does engine oil cause cubs?

The driver was an experienced driver and could see at a glance that it was flooded. He had seen this kind of situation before.

"What should we do?" the supervisor asked, looking at the driver.

"It can't work now. Call the master right away to have a look. If it doesn't affect other parts, it won't be good. Then the engine may be useless." The old driver only knew from experience that the engine oil had water in it.

He doesn't know what it looks like or where the problem is.

"By the way, send the computer to the manufacturer and ask them to repair it." The supervisor thought of the manufacturer first.

"Put it down. This car has 5,000 hours on it. The engine manufacturer's three-guarantee is 1,000 hours or half a year. Look at the car's schedule. You don't have to waste that long-distance phone bill." The old driver said.

"We don't want them to be free, we have to pay them to come and help us with repairs," the supervisor said.

"It's true. It would be best if we could have masters from regular engine manufacturers come, but are they willing to come? I heard that the engines of Tang Dynasty Power Company are a famous engine company in the country, and their products are also sold to domestic

Many loaders are equipped with their products, and the vehicles within the three-warranty period are too busy. Will people outside the warranty pay attention to us?" the driver analyzed.

"We'll find out if we can call first." After the supervisor said that, he returned to the county seat and made a call, but was politely rejected by Yaya, the operator at the headquarters.

"I said no, right?" When the supervisor came back, the old driver heard what the other person said and said.

"Now we can only look for it from outside," the supervisor said.

At this time, the old driver said: "My friends, I know a few maintenance masters who I heard were working at Tang Dynasty Power Company, and they were the most regular masters. Later, they came out to work alone. Their skills are not to be said, and they can be regarded as guerrillas.

"It's a regular army. It would be best if we could get them to come, but it's not far from here. I'm in Beijing, so I don't know if they're willing to come," the old driver said.

"Is it really from the manufacturer?" the supervisor asked excitedly.

"It's true, and it was brought out by Wang Shi, the boss of Tang Dynasty Dynamics Company. Later, I heard that he was dissatisfied with the boss of Tang Dynasty Dynamics Company and deducted their funds for no reason. The four of them went out to work alone and opened a store in Beijing.

Repair shop."

"No way, Tang Dynasty Power Company will deduct employees' salary funds? I don't believe it anyway." The supervisor said doubtfully, "Now you go talk to your friend and ask him to help invite them over." Anyway, the car can't be used now.

Come on, the driver doesn't have to go to work today, so just leave this matter to him.

In the end, the old driver didn't know how much money was appropriate, so the two of them went to make a phone call together.

After some discussion, the last person invited Haorou and his son Hao Jianguo to come over. The round trip expenses were paid by the user, and the salary was three hundred, including food and accommodation.

Haoruduo's technology is not mentioned. I first tested the oil cooler and found that there was no problem. It may be caused by the cylinder liner sealing ring. I have to disassemble it and take a look. I can probably guess a good deal.

Hao Rouduo took his son Hao Jianguo and started working.

"Let me tell you, our technology is inherited from Tang Dynasty Power Company. My father was a master in the service department of Tang Dynasty Power Company. It is the same as the masters from the manufacturer coming to repair it. Although it is a loader,

But the engines are all the same, they just changed the vest." His son Hao Jianguo said to the driver supervisor standing aside while loosening the exhaust pipe screws.

"Shut up!" Haoruduo heard his son mentioning his old club and scolded his son.

"Dad, what can't you say? Without Butcher Zhang, we wouldn't have meat to eat? Look, isn't our repair shop very popular in the past few years? Although it's a loader, look at the appearance of this engine. It's the same as before.

It's not a piece of cake for you." After Hao Jianguo finished speaking, he saw the supervisor saying flatteringly: "Don't worry, as long as all the accessories are available, it will definitely be done for you in less than a day," Hao Jianguo said.

"Then thank you two masters." The supervisor felt relieved after hearing Hao Jianguo's words.

It seems that it is true that the two of them came from the manufacturer.

In the past few years, four people have established a repair shop. Each of them does not have an apprentice, but his own son. Hao Rouduo has Hao Jianguo, Zhang Taiqin has his son Zhang Mingshan, and Wan Bodong has his son Wan Haikuo.

Hao Rouduo removed the upper components such as the cylinder head on top, while Hao Jianguo removed the oil pan screws on the bottom.

The two of them were very fast, and by noon they had almost dismantled it. They pulled out the cylinder liners one by one and saw obvious wrinkles on the cylinder liner sealing ring of the fourth cylinder.

"Did you see it? It's here. The wrinkles here are not elastic enough, and water seepage occurs under the pressure of the water pump. So the water drips along the cylinder liner and into the oil in the oil pan below, causing water to enter the oil..." Hao

Rouduo pointed at the cylinder liner sealing ring and explained the key to his son.

"Well, then the next step is to wait until all the accessories are put back together and then we'll be done?"

"Well, unfortunately, I may have to stay here for two days." Haorudo said.

So Haoruduo wrote down the replacement parts and gave them to his supervisor.

The chief officer took a look and saw on it an engine overhaul kit, 12 cylinder liner seals, 6 sets of piston ring assemblies, 6 cylinder liners, six cylinder valves and valve seat rings.
