Back to the 80s Machinery Factory

Chapter 399 Vehicle parts are too difficult to obtain
Watching Chen Luyang, her fingers flying away from the calculus book like a little quail,

Teacher Zhou gave him a somewhat disdainful look, picked up the chalk, and started writing formulas on the blackboard again to begin her lesson.

Chen Luyang stared blankly at the blackboard, not even knowing what to write down.

His eyes were fixed on the new formula that had been erased and rewritten on the blackboard.

Chen Luyang slowly closed the pen.

It's firm...

Can't understand.

I'm not going to remember anymore, boohoo...!
but! !
Even if others don't understand, dignity must not be lost.

Chen Luyang imitated the chubby boy, casually crossing his arms and nodding occasionally in response to Teacher Zhou's words.

You know what...

Even though I couldn't understand it, the feeling of nodding slightly was absolutely amazing!!!

There's a wonderful feeling of having everything under control.

But before Chen Luyang could even enjoy the wonderful feeling, Teacher Zhou spoke up.

"...Seriously, why are you always nodding like that, male classmate?"

Chen Luyang: ? ? ?

Teacher Zhou put down the chalk: "You've been nodding the whole time, what are you nodding at? Huh?? Let me ask you, what are you nodding at?"

Tell me, what are you doing here?

"You can understand me, so you nodded?"

Instantly, everyone in the classroom followed Teacher Zhou's gaze and looked at Chen Luyang.

Suddenly, Chen Luyang's face turned bright red!

"Teacher... I'm afraid I'll fall asleep, so I'm nodding to stay awake," Chen Luyang whispered.

“If you’re afraid of getting sleepy, then stand up and listen.” Teacher Zhou’s eyes saw right through him.

"You keep nodding like that, it's making me dizzy!"

Chen Luyang's expression stiffened: "...Okay, teacher."

stand up,
Chen Luyang braced herself and stood beside the classroom under everyone's gaze.

That's why they say traditional culture is profound and extensive.

The same scene, if it were in a political economy class, would be the focus of everyone's attention.

If it were changed to a higher mathematics course, it would be called "Under the Public Eye".

Standing to the side, Chen Luyang dared not nod.

But as Chen Luyang stood there, listening to Teacher Zhou's incomprehensible lecture, she really started to feel sleepy...

Yawning came one after another, and tears streamed down my face.

His eyes were red.

The little girl sitting next to him couldn't bear to watch any longer and secretly handed him a handkerchief.

Chen Luyang had no right to accept it!
Quickly wave your hand below to indicate that you don't need it.

But when he raised his hand and waved, Teacher Zhou saw it as him making advances towards a female classmate.

"Duang!"

It was another vicious sound of a blackboard eraser hitting the blackboard.

"Listen up, everyone! Don't do anything sneaky."

As Teacher Zhou spoke, she rolled her eyes at Chen Luyang.

Chen Luyang: ...I'm more wronged than Dou E!
My morning classes were a complete mess.

Even though he was being punished by standing in the corner and engaging in "tricks," Teacher Zhou still asked him one question:
"Did anyone not understand what I just said? Is there anything wrong with it?"

Teacher Zhou looked around and finally fixed his gaze on Chen Luyang.

"I'm done talking about this part."

Chen Luyang met Teacher Zhou's gaze with unwavering resolve, stubbornly remaining silent.

What's wrong...?

I didn't understand anything from the very first lesson; the whole thing was full of questions.

Teacher Zhou gave him a disapproving look, seemingly annoyed that he didn't know how to cherish the opportunity.

At last,
Teacher Zhou wrote the homework on the blackboard and asked the students to copy it down and hand it in next week.

Chen Luyang wouldn't even bother copying... Pshaw!

So what if I copied it?
It's as if copying something will automatically make you know how to do it.

It's better to go back and copy the homework from the chubby boy.

In the large calculus classroom, other students, seeing Chen Luyang standing motionless and unwavering in the room, couldn't help but mutter to themselves:
This kid's pretty arrogant!

……

As soon as the advanced mathematics class ended,

Chen Luyang almost avoided walking past Teacher Zhou. The big, tall dog sneaked into the crowd, its steps unsteady as it followed the students out of the classroom.

"I heard the cafeteria has braised beef today."

Little Fatty Zheng Zhe loves meat; his eyes light up when he hears the mention of braised beef.

He hadn't finished speaking when...
Chen Luyang wrapped an arm around him and said, "Let's go!"

The two walked out like good brothers, and as they walked, Chen Luyang said with a friendly smile:
"Zhezi?"

Zheng Zhe became somewhat wary: "What are you going to do?"

Chen Luyang, shamelessly, said, "Um...can I copy your calculus homework after you're done?"

Zheng Zhe rolled his eyes: "That's disgusting! I thought you wanted me to do something! I'll give it to you after I finish my homework."

Chen Luyang exclaimed happily, "That's exquisite!"

Zheng Zhe asked curiously, "What's this academic research group all about?"

Chen Luyang said mysteriously, "You'll find out this afternoon."

……

In the afternoon, economics students gradually arrived at their classrooms.

Although we haven't known each other for very long

However, since we attended classes together every day and rehearsed extensively, we got to know each other quite well.

Everyone was chatting happily in the classroom when they saw the classroom door being pushed open.

Teacher Shang walked in carrying a large, heavy stack of documents.

The thick stack of documents was bound with hemp rope, and the edges of the papers showed the grayish-blue color stained by the ink of the lead type, clearly indicating that they had just been brought back from the printing room.

Upon seeing this, Tao Runze and several other class committee members immediately ran to the podium to help unpack and organize the items.

"One for each student," Teacher Shang said to the whole class.
"I'd like to take this opportunity to announce two things to you all today."

"Firstly, to facilitate everyone's learning, the department has formed an academic research group, with Chen Luyang serving as the academic committee member."

The students in the class remained calm.

Being an academic committee member isn't a particularly prestigious position.

Furthermore, everyone saw what Chen Luyang wrote on the blackboard during the advanced mathematics class. There's nothing to be surprised about.

Professor Shang continued, "Secondly, the department has added a new course called 'Guided Reading of Original Works in Economics,' which is held every Wednesday evening from 6 p.m. to 9 p.m. The lecturer is student Chen Luyang, and the textbook is the internal material we are currently distributing."

"Keep it safe and study it carefully."

Damn it...

Accompanied by Sun Legen's involuntary expression of emotion,

The whole class erupted!

In an instant,
Pairs of eyes, like spotlight bulbs, suddenly shone on Chen Luyang, their expressions filled with disbelief!

It's one thing for Chen Luyang to tell the original work to the public in a grassroots manner as a student.

However, the department specially applied for a course for Chen Luyang to teach, which was a different story!
Is this guy even human?!
They were all freshmen, and they were all in the same class.

They're even able to offer open courses at Peking University now.

"Cultural Committee member, since you're giving us lectures, should we call you 'teacher' or something else?" Gao Xiaolin blurted out in her loud voice.

Chen Luyang felt a chill run down his spine and quickly waved his hand, "What kind of teacher am I! Just call me Little Chen~"

If this were in a machine factory, he would accept it if someone called him "Teacher Chen" a few times.

Not to mention that the "teachers" here are all highly skilled and knowledgeable experts.

Every single one of these students in the room got into Peking University through the real test.

In terms of academics, they are all better than him, a special admission student.

Although Chen Luyang was modest, Teacher Shang had no intention of letting him off the hook.

"It may not be now, but it might not be in the future. Have confidence."

Looking at Teacher Shang's kind smile, three small question marks popped up on Chen Luyang's head.

What do you mean?
What does this mean?
Before he could think it through, the textbooks had already been distributed to everyone in the classroom.

Chen Luyang looked down.

The three lines of bold small print on the cover are clearly visible:
"Samuelson's Original Works on Economics: A Guided Reading - Volume 1"

Manuscript compiled by: Chen Luyang (Class 1, Department of Economics)
Translation team of the Department of Economics.

Upon seeing her name on the cover, Chen Luyang raised her eyebrows slightly, feeling happy.

I love doing things that give me recognition and status!
Teacher Shang continued, "Students, this internal document is a manuscript written by Chen Luyang. It was specially compiled and printed after being reviewed by the faculty. Please cherish it!"

"And the academic research group I just mentioned also holds weekly meetings. The content of these meetings is not limited to textbooks; the focus is on training everyone to read original works in English and to do theoretical derivations."

"Today is the first research group discussion meeting."

Teacher Shang paused, then smiled at Chen Luyang, his tone slightly teasing:

"Next, Chen Luyang will come up to the stage to host. Let's give her a round of applause!"

……

at this time,

West Railway Station Automobile Maintenance and Repair Center

A 212 was lying on the repair bench, its hood sticking up high.

"The master cylinder is leaking oil again," Zuo Zhuo said as he leaned over to check. "This is the fifth one this month."

"Write it all down." Director Lu turned to Li He and instructed, "Vehicle model, malfunction, time taken, what was replaced, we need to keep all the data."

"it is good!"

As Li He spoke, he took a copy of "Daily Maintenance Summary" from the shelf.

The summary table is very comprehensive, with "vehicle model", "fault type" and "replacement part number" all listed in detail.

In particular, there was a blank box in the bottom right corner of each page with the words "Workers' Suggestions".

Each page was densely covered with instructions and descriptions.

The records are particularly comprehensive regarding the selection and assembly of parts!
Two months ago,
No one could have imagined that the most frustrating thing about opening a car maintenance and repair center in Pian'er City would not be having no work, but being unable to do it!
Behind every car in Pian'er City lies a story.

Some were decommissioned military vehicles, while others were small batches of engineering vehicles purchased locally. Even for the same model, Pian'ercheng used Type A parts, Hongjin used Type B interfaces, and Beihe even had modified vehicles produced from old molds from the late 1960s.

Everywhere is different.

The missing or replacement parts are different for each vehicle; there is no uniform standard.

Initially, Lu Chu fully mobilized his grassroots support, searching everywhere for people to tinker with the parts.

However, these parts were either shipped from the main factory warehouse or obtained from other units or fleets through personal connections and favors.

Waiting for parts takes longer than repairing a car!
Fortunately, Director Lu and Zhang Guoqiang are both experienced craftsmen who came from the workshop, possessing superb skills and rich experience.

Lacking spare parts, they simply modified and assembled existing components to create replaceable parts, and then recorded the data.

When Zuo Zhuo removed the master cylinder, the brake fluid inside had already soaked the lower half of the cylinder.

"Look at this piston."

Zuo Zhuo reached in and rummaged around. “The sealing ring has long since shriveled up, and there’s a scratch on the entire cylinder wall… Xiao Li, open the third drawer on the shelf and give me the parts inside.”

Li He took out a main pump part that looked similar but had a different connector, handed it to Zuo Zhuo, and asked in confusion:

"Brother Zuo, isn't this the part we used to equip the 140 main pump last time? These two interfaces are different!"

"The interface is different, the thread angle is different, but the cylinder diameter is the same. A couple of days ago I tried to make a copper connector rotor, and then added two layers of sealing gaskets, maybe it can be connected."

Zuo Zhuo took the parts, turned around and walked to the workbench behind him. He cut the interface hose that he had removed from the old car shorter, added a custom-made adapter copper pipe, and re-welded it in place.

Then use the old method again—cut several layers of tar paper into washers and carefully seal the seams.

Once everything is settled.

Zuo Zhuo carefully replaced the new parts on the car body. As the car started again, the brake pedal slowly rebounded. He pressed the test line all the way down and then released it—clean and crisp, without any pressure loss.

"It's done." Zuo Zhuo wiped his sweat. "Although it was a gamble, as long as it was done steadily, it's fine."

"Mmm." Li He lowered his head and quickly wrote down all the vehicle malfunctions, replacement models, and solutions in his notebook.

Then, he turned around.

Behind the workbench, there was also a "laboratory" made up of several wooden tables temporarily pieced together.

Zhang Guoqiang, Tan Rensong, and Liu Kangwen, three veteran craftsmen, were gathered around a pile of parts on the table, deep in thought and studying them.

"The cracks in the outer casing of these shock absorbers are all in roughly the same location, near the 35-degree angle line; all three samples are identical," Tan Rensong said, pointing to the cracks.

"This isn't a broken part; the mold angle was wrong... Plus, the steel tension wasn't high enough, so the tensile strength is definitely problematic."

On the other side,
Liu Kangwen placed a disassembled carburetor on the wooden table. He squinted at the nozzle, poked at it a few times with tweezers, and then exhaled.

puff……!
"Look at this thing, the nozzle is almost clogged up to the size of a pinhole."

As Liu Kangwen was cursing, his eyes suddenly lit up, as if he had remembered something.

"Old Zhang... do you remember that Jeep that came to be repaired last time?! Their nozzles have a similar structure to this one!"

"The nozzle positions are all the same, it's just that the angle of the connector is different by a little over a millimeter."

Zhang Guoqiang's eyes lit up: "If we make an adapter here, cut some copper pipe, add sealant, and match it with the Jeep's main nozzle, could we install it?"

Liu Kangwen said, "Don't we happen to have a few Jeep nozzles in the small warehouse? Why don't we give it a try? Let's practice on scrap parts first?"

Zhang Guoqiang immediately stood up: "Let's go! Let's go to the back room and pick up some copper pipe ends."

The two of them, talking back and forth, had already reached the doorway of the small room filled with discarded parts.

"Hey...where did it go? I remember there was some before...where can I get it?"
