Liu Xiangguo took Liu Xiangdong to the town on a motorcycle, and having a motorcycle at this time was also something worth showing off.

The gate of the starch factory was closed, but Liu Xiangguo took Liu Xiangdong to enter through the small door, and the uncle guarding the door didn't even ask.

Quietly in the factory, Liu Xiangguo found Brother Zeng who was in charge of equipment in a dormitory.

"Old cousin, this is my cousin Xiang Dong, he studied mechanics at East China University of Technology, and he will graduate next year. Liu Xiangguo introduced Liu Xiangdong to Brother Zeng.

directly said that Liu Xiangdong was a junior student, which Liu Xiangdong had agreed with his cousin in advance. If it is said that Liu Xiangdong is just a student who has just graduated from high school, who would dare to let him touch the equipment.

Brother Zeng looked at Liu Xiangdong and didn't doubt his identity as a college student, he just didn't understand why Liu Xiangguo introduced a college student to him, could it be that Liu Xiangguo, a cousin, would return to this town to work after graduation?

"Brother Zeng, I followed my mentor in my sophomore and junior years to intern in major factories in City B, and I went to XX factory, XX factory, and XX factory. I have touched, dismantled, and repaired some of the equipment in these factories. I heard that the equipment in our factory was broken, so I asked my cousin to take me to see it. Liu Xiangdong said confidently.

I followed my mentor to intern in major factories in City B, and I touched, dismantled, and repaired some of the equipment in the factory. Brother Zeng sounded, he had a sense of loftiness, and thought to himself, he deserves to be a famous college student, and his knowledge is extraordinary.

"Ah Dong, do you want to help Boss Zhou repair the machine?" asked Brother Zeng.

"Yes, can Brother Zeng take me to see the machine first. If I can fix it, I'll give it a try. If you can't fix it, I won't move, and I won't cause trouble to you, Brother Zeng. Liu Xiangdong's words were very old, and Brother Zeng had nothing to say when he heard it.

"Adong, look at what you said. If you are a famous college student and can help us, what else do we have to say. This will take you to see it. If you can really help us, I have to show the two people in the equipment factory to see it, don't look down on us countrymen. It seems that Brother Zeng hates the two people in the equipment factory.

The three of them came to the factory together, and Brother Zeng pointed to a piece of equipment and said: "Adong, this is the machine, the last shift was powered on that day and only turned around, and it clicked and didn't move." My preliminary judgment is that one of the teeth in the gearbox is broken. The after-sales service from the equipment manufacturer also said the same. The man also said that it was very troublesome to repair, and it would not take long after repairing, so it was better to buy a new one. I always think this guy is a liar, but I can't talk about him, I'm not as familiar with this machine as he is. ”

Liu Xiangdong asked Brother Zeng to electrify the machine, listened to the sound of the motor with his ear close to the machine, and then picked up a wrench and tapped it twice at the place where the gearbox was transmitted.

"Adong, what do you think? Can you really cultivate?" Brother Zeng asked a little nervously, Liu Xiangguo was also a little nervous, he was afraid that Liu Xiangdong didn't know how to pretend to understand, because only he knew that Liu Xiangdong was not a college student who was about to graduate, but just a high school student who had just graduated.

Liu Xiangdong smiled easily and said, "Brother Zeng, don't worry, I know the problem of the machine." This kind of transmission gearbox, I have dismantled it several times in XX factory in B city, and I have also repaired it twice, so I should still be sure. Brother Zeng, you see, the four sets of gears of the transmission gearbox are connected in this way. The most stressed is this group of gears, and the broken tooth is one of the teeth on the most stressed side. This kind of machine will be designed with the force imbalance in mind, so this set of gears can be interchangeable left and right. As long as we disassemble the gearbox, weld the broken tooth on, and then swap it left and right, the machine should be able to last for two or three years. ”

Liu Xiangdong said while drawing on the ground with a piece of chalk, Brother Zeng looked at the gear set drawn by Liu Xiangdong, and knew that Liu Xiangdong was really very familiar with this kind of machine, such a precise internal structure Liu Xiangdong drew effortlessly.

"It's that simple?" asked Brother Zeng.

"Of course it's not that simple. Even if the broken tooth is welded back, and then swapped left and right, the most important and critical thing is to adjust the four sets of gear sets to the balance of force when they are newly installed, otherwise the teeth on this side will be broken in less than a month. Last year, I only used a pack of cigarettes to take out his box-pressing stunt from the mouth of the master of XX factory in B city, and I learned how to adjust four sets of gear sets. ”

"Did you really learn a trick with just one pack of cigarettes?" a voice on the side suddenly asked.

Liu Xiangdong, Liu Xiangguo, and Brother Zeng turned their heads to look, and saw a middle-aged fat man standing on the side, he was the factory owner Zhou Million. I don't know when he came, or how long he listened to it.

"Boss. Liu Xiangguo and Brother Zeng shouted.

"Uncle Cousin. "Liu Xiangdong is not a worker in the factory, he can only call his cousin.

"Xiang Guo, is this someone from your village?" Zhou Million asked.

"Boss, Ah Dong is my cousin, and his father is my Uncle Qiyuan. Ah Dong is a student at East China University of Technology and studied mechanics. ”

"It's the child of the old cousin of Qiyuan, yes, he learned very well. ”

"Boss, Ah Dong said that he can repair this machine. Brother Zeng said immediately.

Zhou Million didn't express his position immediately, but continued to ask: "Adong, do you really learn a unique skill with just one pack of cigarettes?"

Liu Xiangdong replied embarrassedly: "I invited the old master to have a good meal with my senior brother, and I also gave a cigarette." ”

Zhou Million nodded and said, "The current students are amazing, I thought they were all nerds." Adong, can you tell me how to balance the four sets of gears?"

Liu Xiangdong was not conservative, and replied directly: "The key is at the diagonal three groups of bolts, and finally it has to be checked by the paper pressing method, as long as the indentation is consistent, it can be confirmed." ”

"Are you really sure that you can fix the machine?" Zhou asked again.

"Uncle Cousin, I'm 90% sure. ”

"Okay, the machine will be handed over to you, and if it is repaired, your benefits are indispensable. ”

Liu Xiangdong didn't expect to get the nod of Boss Zhou so smoothly.

After Zhou Million left, with the help of Brother Zeng and Liu Xiangguo, Liu Xiangdong began to dismantle the machine.

When I dismantled the transmission gearbox, as Liu Xiangdong said, one of the strongest groups had a tooth disconnected.

At this moment, two more people came in the factory, one of them saw Liu Xiangdong and the three of them dismantling the machine, and Lao Yuan shouted angrily: "Who are you, how can you disassemble the machine casually." ”

Brother Zeng glanced up, and then whispered to Liu Xiangdong: "Adong, don't pay attention to them, these two people are from the equipment factory, one is a salesman, and the other is after-sales service, both of which are not good things." ”

Seeing that the three of them were unmoved, after the two approached, one of them threatened Brother Zeng: "You dismantle it yourself, and our factory can no longer guarantee this machine." If you can't install it back, or if you can't install it well, you can only buy our new machine. ”

Brother Zeng didn't even raise his head, and said to Liu Xiangdong: "He is an after-sales technician Xu Gong." ”

"XCMG, in your factory's sales contract, is there a clause that users are not allowed to open by themselves?" Liu Xiangdong didn't look up, and asked directly.

"It's not there, but it's the rule of the industry. XCMG replied coldly.

"Whether the industry regulations are greater than the national regulations. Liu Xiangdong asked again.

XCMG was speechless, and another salesman surnamed Ma had to say: "XCMG, let them repair it, if they can't repair it, they can only buy a new machine." ”

"How do you know we can't fix it. Brother Zeng asked unconvinced.

"Didn't you hire a master yesterday, and he didn't even dare to dismantle the machine. Today, this young calf is not afraid of tigers, don't think that you can just disassemble the machine and put it back on, I can guarantee that within a week, the machine will have to stop. Ma sales arrogantly said, at this time the competition in the machinery industry is not as fierce as more than ten years later, equipment manufacturers to customers, there is not that enthusiasm for God.

"Isn't it just a three-point positioning, pressing paper inspection? Liu Xiangdong said lightly.

Xu Gong was taken aback when he heard this, he didn't expect that the young technician in front of him still knew this secret trick.

"Even if you've heard of this method, but will you?" Xu Gong didn't believe that the young Liu Xiangdong would be able to do that trick.

"If you want to know, just watch from the sidelines. Liu Xiangdong shot back.

XCMG and Nama Sales have been watching from the sidelines and refuse to leave.
