Return to the red age

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

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

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

"This is a transmission gear, driven through a chain and a bearing at the back." Kyoto 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 such as modern Siemens. Even if you buy them back, they have a machine moving system that will detect that your machine has moved and lock 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.

The bangs were dismantled under the guidance of three apprentices, and the various parts were clearly identified, and then put 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?"

"We should do it."

"Director Liu is so strong."

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, Director Liu, thank you, Director Liu."

Maintenance workshops don't have much business. Nowadays, motorcycle owners can basically repair their own motorcycles. Only if there are major problems will they be sent back to the factory for repairs.

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, it is the first time to ride a modern light bicycle, such as a 28-bar, which feels a bit awkward.

The three apprentices also learned engineering very quickly. By the time they got off work, everyone was basically able to ride. Section Chief Hou didn't say anything after seeing it. There were no tasks in the maintenance workshop.

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 his brand new bicycle back to the courtyard. The one who came back was the earliest, because the bus might not be able to catch up with the bus because the bike was fast.

Qin Huairu, the first aunt, and the third aunt were chatting at the door of the third aunt. The three women were waiting for their men to come back so they could cook or something.

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

"Third aunt." Liu Hai also nodded in greeting.

"Is this a reward given to you by the factory?" The third aunt got up and came to the bicycle. She 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.

"Yeah, that's right." Liu Hai nodded.

My aunt is also envious. It’s not that her family doesn’t have money to buy bicycles, but they don’t have bicycle tickets.

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 was still smiling.

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

Liu Hai smiled and said nothing 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 a public bicycle. It was said that he would get a private one later, but he had 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 his bangs. He felt very uncomfortable, so he dragged Qin Huairu, who was watching the fun, 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 to ride?"

Before Liu Hai could speak, Xu Damao said angrily: "What are you talking about? What are you talking about? This is a new car. Who's responsible if it gets damaged? You need to learn how to drive and look for those old cars."

"Yes, this is brand new. 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. In his heart, Liu Hai didn't value the bicycle, but how to put it, after the first one, there will be a second one. It would be bad if he makes the neighbors uneasy because of the bicycle in the future.

The crowd gradually dispersed, and Xu Damao whispered: "Brother, I will ask you to drink wine later to celebrate. Don't lend the car to others. There are more than a hundred people in this yard. If you don't lend one, everyone will have 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. Moreover, it's difficult to recycle them if they are borrowed. If they are damaged, they will need money to repair, at least for spare parts.

Liu Hai looked around the house and found nothing for Xu Damao. He thought to himself that when he returned to the village to get some wild rabbits, he would treat Xu Damao, the second uncle, by the way.

"Brother Liu, bicycles are awarded by the ministry, but there are no rewards from the factory?" Xu Damao asked Liu Hai in a low voice after taking a few sips of wine at Xu Damao's house in the evening.

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.
