It is very simple to weld the broken tooth, and after the gear is swapped left and right, the next thing is a unique skill that only ordinary masters understand.

How to ensure the balance of the force of the four sets of gears, the key lies in the three screws.

The screw must not be too loose or too tight. The occlusal surface of the gear should not be too wide or too narrow.

After the gear is engaged, the indentation is visually inspected until all the indentations are basically the same, and then the gear set is adjusted.

Xu Gong looked at Liu Xiangdong's skillful movements, and the expression on his face was unpredictable.

After more than two hours, the machine was reassembled.

"Brother Zeng, it's time to turn it on. Liu Xiangdong said confidently to Brother Zeng.

"Okay, Adong, I believe in you. ”

The switch was struck, and the machine rumbled into spins.

Liu Xiangdong put his ear on the transmission gearbox, listened for a while, nodded, and then said to Brother Zeng: "No problem, I will disassemble it and readjust it every six months in the future." Brother Zeng, you learned it just now. ”

"Adong, I've written it down. Thank you so much for passing on such a great skill to me. ”

"Brother Zeng, your own family, don't be so polite. ”

"Adong, you want it. ”

XCMG also went up and put his ear to the transmission gearbox to listen for a while, and then left the factory without saying a word.

Seeing that Liu Xiangdong really repaired the machine, Liu Xiangguo, who had been tense, breathed a sigh of relief.

"Adong, I'll go and tell the boss the good news first, you and Aguo will stay and have dinner together in the evening. ”

"Okay, Brother Zeng, we'll wait for you. ”

At dinner in the evening, Zhou Million did not show up, and Brother Zeng accompanied Liu Xiangguo and Liu Xiangdong to dinner.

Brother Zeng saluted Liu Xiangdong three glasses of wine and said, "Ah Dong, if it was in ancient times, I would have called you a master if I learned your unique skills." These three glasses are my apprenticeship wine, and I will ask you to teach me more in the future. ”

"Brother Zeng, I can drink the wine, but I don't dare to accept it. I'm still a student, and we just communicate with each other. ”

"Okay, let's talk more about it then. Boss Zhou was going to accompany a client tonight, so he didn't come, and he asked me to talk to you. Boss Zhou also said that he didn't know how many red envelopes to give you. ”

Brother Zeng's sentence is to explore the reserve price in Liu Xiangdong's heart on behalf of Boss Zhou.

"Brother Zeng, Boss Zhou is my cousin, and I haven't come out to work yet, how much my cousin gives is a heart, and he will fund me to go to college. Speaking of the value of this technician, the instructor who led the team at our school told us a story of 'drawing a line is worth $10,000'. ”

"'Draw a line is worth $10,000'? Adong, tell us about it. ”

"This is the story of a foreign technician. At one time, a valuable machine broke down in a factory, and many maintenance personnel could not find the reason. Finally, a very famous engineer was invited. After the engineer came, he analyzed it for a long time, and finally drew a line in one place of the machine, and told them to open it and find the red line. Sure enough, the reason was that the red thread burned out. The engineer was asked to quote a price for repairs, and the engineer quoted a high price of $10,000. Someone asked, 'Is a line worth $10,000?'. The engineer replied, 'No, I'll only charge one dollar for drawing a line, and the other nine hundred and ninety-nine dollars for knowing where to draw the line.' ”

"Well, that makes sense. Brother Zeng sighed.

After eating, Liu Xiangguo took Liu Xiangdong back to the village on a motorcycle.

At home, Tang Yuhua and Liu Qiyuan are still waiting for their son to come back for dinner.

Seeing Liu Xiangguo come in with Liu Xiangdong, Liu Xiangdong's face was still red, obviously drunk.

"Xiangguo, did you take Ah Dong for a drink?" Liu Qiyuan asked.

"Uncle Seven, it's not me who invited Ah Dong to drink, it's our boss Zhou who invited Ah Dong to drink. Liu Xiangguo said proudly.

"Why did Boss Zhou invite Ah Dong to drink. Liu Qiyuan asked puzzled.

"Seventh uncle, Adong is amazing today, he helped Boss Zhou repair a big machine. ”

"Adong can fix machines, you're not lying to me, are you? Liu Qiyuan was a little unconvinced.

"Uncle Seven, when did I lie to you. I've been at home for the past few days, just because the machine in the factory is broken, and I can go to work again tomorrow. Boss Zhou also said that he would give Adong a big red envelope. ”

"Where's the red envelope?" Tang Yuhua asked on the side, of course, what she was most concerned about was money.

"I haven't given it yet, and Boss Zhou doesn't know how much to give. ”

Tang Yuhua thought in his heart, how can he give two or three hundred to be appropriate.

What Liu Xiangguo thought was that he had to give at least five or six hundred.

Liu Qiyuan had no idea, he didn't expect that his son would start making money.

At first, Zhou Million thought that it would be appropriate to give five or six hundred, but then he heard Brother Zeng's report, listened to what Liu Xiangdong said, and the story of 'drawing a line is worth ten thousand dollars'. Only then did he decide to raise the red envelope to 2,000 yuan. That's three months' wages for an average worker in two OOO years.

At noon the next day, Liu Xiangguo came back in a hurry and slapped a thick red envelope to Liu Xiangdong: "Adong, this is the red envelope that Boss Zhou gave you, hurry up and look at it, I don't know how much it is." ”

Liu Xiangdong opened it, and on the very edge was a stack of thick old man's heads, counting them, there were twenty in total.

"Wow, Boss Zhou is really generous, he actually gave two thousand yuan. Liu Xiangguo exclaimed.

Tang Yuhua heard a voice in the inner room and came out to ask, "Who gave 2,000 yuan?" ”

"Aunt Seven, Boss Zhou gave Ah Dong 2,000 yuan to repair the machine. Liu Xiangguo said happily.

"Ah, how can you fix a machine for so much money. Tang Yuhua couldn't figure it out.

"Aunt Seven, a new machine is worth more than 100,000 yuan. Others don't know how to cultivate, so Adong will be, so it's worth the price. Liu Xiangguo explained.

Liu Xiangdong handed the money in his hand to Tang Yuhua and said, "Mom, this money will pay me for my schooling." ”

"Last night, your dad and I were still calculating the difference of 3,000 yuan in tuition, and with 2,000 yuan, it was not far off. Tang Yuhua quickly took it and said happily.

"Aunt Seven, Adong has such a good technique, maybe someone will ask him to repair the machine in two days, and he can still make a lot of money. Liu Xiangguo said.

"How can there be such a good thing. Tang Yuhua did not expect his son, who did not study in college, to earn money now.

Liu Qiyuan came back from outside and was greatly surprised when he heard that his son had earned 2,000 yuan to repair the machine.

In the evening, the happy Tang Yuhua killed another local chicken.

Three days later, Brother Zeng came to Liu Xiangdong and said that the owner of a factory in a neighboring town heard that Boss Zhou said that Liu Xiangdong would repair machines, so he wanted to ask Liu Xiangdong to help in his factory.

If there is business coming to the door, of course Liu Xiangdong will not refuse. Since he had to go to a neighboring town, and he would definitely have to spend the night outside, Liu Xiangdong had to report to his parents.

"If you know how to cultivate, don't be arrogant. Liu Qiyuan taught.

"Take as much as people give, don't ask for money. This is Tang Yuhua's admonition.

Under the leadership of Brother Zeng, Liu Xiangdong came to a pine resin factory in a neighboring town.

In the past two years, the market of pine resin has been very good, and after the pine resin factory added a new machine, it still could not meet the production requirements. The financial pressure to add a new machine is too great, and the Huang boss of the factory is not very willing. After hearing Boss Zhou talk about Liu Xiangdong at the dinner table, Boss Huang wanted Liu Xiangdong to try.

"Adong, I'll just say it directly. A new machine like this costs seventy or eighty thousand. If you can help me fix this old machine, which will last at least a year, I'll give you five thousand dollars. Boss Huang said briskly.

There must be a brave man under the heavy reward, such a simple machine is not difficult for Liu Xiangdong, but Liu Xiangdong still said modestly: "Boss Huang, then I'll try." ”

Three days later, the old machine was spinning again.

Boss Huang didn't say a word, and in front of Liu Xiangdong, he pointed out fifty old man's heads.

When Liu Xiangdong handed over the fifty old man's heads to his mother Tang Yuhua, Tang Yuhua thought he was dreaming. Liu Qiyuan looked at the large stack of money and felt that his skills could not catch up with the times. The fact that his son earned in three days was what he had earned in two years, which made him unacceptable for a while.
