Courtyard light

Chapter 46

"Director Liu, this is the cylinder liner, this is the piston, this is the spark plug, this is..." the three apprentices said while instructing Liu Hai to dismantle the engine.

"Ours is a single-cylinder engine, and there are also two-cylinder engines."

"This is a carburetor. This is the most precise thing. If it breaks, you have to change it."

"This is the transmission gear, which is driven by the chain and the bearing at the back." The Jingdu Motorcycle Factory makes three-wheeled motorcycles.

Liu Hai nodded. It was really a bit clumsy to dismantle this kind of engine for the first time. Many modern processing equipment use CNC machining centers, some of which are manual, but most of the time they are used in the assembly process.

Take aircraft engines as an example. There is a lot of emphasis on assembly, including workshop cleanliness, workshop temperature, and even the temperature of individual components.

Take the most advanced CNC machine tools like modern Siemens, even if you buy them back, they also have a machine shifting system, which detects that your machine has moved and locks it directly.

And even if you disassemble the original parts and then reassemble them, you still won't be able to achieve the original accuracy. This is the assembly process. Many parts have temperature requirements when they are assembled. If you can't master the assembly process, then I will give you all the parts. It's not possible, let alone the difference in the materials themselves.

Of course, Liu Hai no longer needs the engine in his hand, so he can just tinker with it.

Under the guidance of three apprentices, Liu Hai disassembled it, recognized the various parts, and then put them back together.

After disassembling and assembling it again, Liu Hai breathed a sigh of relief and said, "Thank you."

"Director Liu, what did you say?"

"What we should do."

"Officer Liu has great strength."

Then Liu Hai asked three apprentices to help him learn to ride a bicycle. When the three apprentices saw the brand-new bicycles, they also swallowed their saliva.

"Director Liu, how about we learn it after you finish it?" The three apprentices are named Zhang Xiaoman, Li Dali, and Gou Rong. Among them, Gou Rong is taller, and the other two are about the same size. of.

Liu Hai nodded: "Of course, we can learn from each other."

"Thank you, Officer Liu, thank you, Officer Liu."

There is no business in the maintenance workshop. Nowadays, basically everyone who drives a motorcycle can repair it by himself, and only return to the factory for repairs if there are major problems.

In the remaining two hours of the afternoon, Liu Hai and the three apprentices learned to ride bicycles from each other. One person rode while the three others controlled the bicycle from behind.

Although Liu Hai can ride a bicycle, they are all modern lightweight bicycles, such as 28 bars. This is the first time he has ridden a bicycle, and he feels a little awkward.

The three apprentices also learned very quickly, and everyone basically knew how to ride when they got off work. Section Chief Hou didn't say anything after reading it. The maintenance workshop had no tasks.

I have to say that riding a bicycle is faster than walking. Of course, you can take the bus without a bicycle, but it costs money, so many people walk back.

It used to take more than half an hour to walk, but now it only takes about ten minutes to ride a bike. Sitting behind Liu Hai is Li Dali, who is driving a man for the first time and is walking crookedly on the street.

Li Dali was feeling frightened behind his bangs. Li Dali put his feet on both sides to stabilize himself if Director Liu was about to overturn the car.

Li Dali lived not far from Liu Hai, and agreed to go to work together tomorrow morning.

Liu Hai pushed the brand-new bicycle back to the courtyard, and the ones who came back were the first ones, because the bike was fast and the bus might not be able to catch it.

Qin Huairu, the first mother, and the third mother are chatting at the door of the third mother. The three women are waiting for their men to come back before they can cook or something.

Seeing Liu Hai pushing the new bicycle, the third aunt quickly said hello: "Xiao Liu."

"Three moms." Liu Hai also nodded in greeting.

"Is this a reward from the factory?" The third mother got up, came to the bicycle, looked at the black bicycle with envious eyes, and asked.

"It's a reward from the ministry." Liu Hai couldn't help but push the bicycle into the house, so he stood in front of the door and talked.

"First Machinery Department?" Aunt Ma also followed and asked in surprise when she heard this.

"Well, that's it." Liu Hai nodded.

The big mother is also envious. It's not that the family doesn't have money to buy a bicycle, but they don't have a bicycle ticket.

Qin Huairu looked at this brand new bicycle with envy in his eyes. The money required for a bicycle was beyond Qin Huairu's imagination. Qin Huairu didn't know how much money his family had, but it was definitely not enough to buy a bicycle.

Just for a while, people came back one after another. The second uncle looked at Liu Hai's bicycle and said enviously while stroking it: "Xiao Liu, you are so awesome."

"Thank you, Second Uncle." Liu Hai still smiled.

"Your matter has been published in the newspaper. I saw it in the newspaper in the office today. It's a man." The second uncle said again.

Liu Hai smiled and didn't say anything else.

Xu Damao also came back, and he was also very envious. Xu Damao had a bicycle when he went to the countryside, but it was owned by the public. It is said that a private one will be allocated later, but it will have to wait.

"Brother Liu Hai, man." Xu Damao felt that Liu Hai was his brother, and he felt proud of the honor Liu Hai received.

The old man’s expression was normal and he didn’t say anything, but he was still very envious in his heart. After all, this was a bicycle.

Xu Damao asked again: "How is it? Have you learned it? If you haven't learned it, my brother will teach you."

"That's almost it. Several of us in the factory learned it together." Liu Hai nodded and said.

Jia Dongxu smoked a cigarette and looked at Liu Hai, feeling very uncomfortable, so he dragged Qin Huairu who was watching the excitement back, and the uncle also left.

When Si Zhu came back and saw Liu Hai's bicycle, he would be lying if he said he wasn't envious of it. Si Zhu didn't have much money either. He had a younger sister who was studying and so on, so his income was high and his expenses were high.

Yan Jiecheng said from the side: "Brother Liu, can I borrow your bicycle to learn how to drive?"

Before Liu Hai could speak, Xu Damao said angrily: "What are you talking about, what are you talking about, this is a new car, if it breaks, who cares, if you want to learn how to drive, look for those old cars."

"That's right, this is brand new, and no one knows what will happen when learning to drive."

"Brother Liu Hai, don't borrow new cars. Repairing them is one thing if they break down. It's hard to talk to neighbors." The others also spoke one after another.

Liu Hai didn't express his opinion, Liu Hai didn't value the bicycle in his heart, but how to put it, if there is the first one, there will be the second one, and it will be bad if the bicycle makes the neighbors feel uneasy in the future.

The crowd gradually dispersed, and Xu Damao said in a low voice: "Brother, I will ask you to drink later to celebrate, don't lend your car to others, there are more than 100 people in this yard, if you want to borrow one or not, everyone has something to say behind their backs. "

"Thank you, brother Xu." Liu Hai nodded. There are so many people in the courtyard, it's hard to say whether to borrow one or not, and it's not easy to recycle after borrowing.

Liu Hai looked around the house, and found that there was nothing for Xu Damao to take. He thought to himself, when he returned to the village to get a few wild rabbits, he would invite Xu Damao, the second uncle.

"Brother Liu, bicycles are rewarded in the department, but there is no reward in the factory?" At Xu Damao's house in the evening, Xu Damao asked Liu Hai in a low voice after drinking a few sips of wine.

Liu Hai hesitated and said, "Brother Xu, I told you not to tell anyone. The factory will give me a cadre establishment."

bang!Xu Damao's eyes widened and his mouth opened wide. The wine glass fell on the table, and Xu Damao's father also dropped one of his chopsticks.
