"Master Cao, if you don't mind, can you let me take a look?"

Cao Shan was wiping his hands with a towel, his hands shook unconsciously, and there was an extra grease stain on his face.

But he didn't notice it, and looked at Li Weidong in disbelief.

This person seems to be a workshop director, right?

Even if you used to be a truck driver, you can do a little bit of repair.

It's just that the three-legged cat kung fu of the truck driver is not useful here at all.

Out of politeness, Cao Shan didn't say anything, just winked at Xiao Meng.

It's a pity that Xiao Meng was also stunned by these words, and he didn't notice it at all.

The first to react was Liang Ladi.

She swallowed her saliva, walked over and said with a smile: "Big brother, this is a foreign tractor, there are no drawings, it's all up to you, it's not that my sister can't trust you, it's just."

Halfway through her words, Liang Ladi felt that something was wrong and quickly closed her mouth.

Sister? Yu Haitang glanced at Liang Ladi suspiciously, and said secretly, this woman is really not serious.

Li Weidong folded his hands and smiled calmly.

"Of course, I haven't seen this tractor either, and I'm not sure. However, even if I disassemble the engine and there is no way to restore it, isn't there still Master Cao. ”

"Now Master Cao has no way to find the problem for the time being, it may be a problem of thinking, if you change someone, maybe there will be new ideas."

"Do you think I'm right?"

Although Cao Shan felt that Li Weidong looked down on the profession of mechanic, he had to admit that Li Weidong's idea still had some truth.

As a master, he also knows the existence of blind spots in thinking.

An obvious mistake, often checked several times, still not found, is a blind spot at work.

Cao Shan nodded lightly: "Since Director Li is interested, if I refuse, it will be unreasonable." ”

"However, our machine shop has a rule that the repair work must be done by yourself."

"If you want to fix a tractor, you have to remove the engine yourself."

Liang Ladi glanced at Cao Shan in surprise.

This kind of regulation was originally intended to avoid apprentices from making noise on the side.

Now that Cao Shan has brought it up, it seems that he is a little embarrassed by Li Weidong's meaning.

Liang Ladi didn't find out, just one night, she began to think about Li Weidong.

No wonder it is often said that there are two paths through a woman's heart, one is the avenue and the other is the path.

The avenue is flat, but the effect is slow.

The trail is rugged, but it reaches the heart.

Xiao Meng also came to his senses at this time.

Seeing Li Weidong's resolute attitude, he said with a smile: "Director Li is also an old driver, and he knows this rule." ”

As he spoke, he took the initiative to help Li Weidong bring tools such as wrenches and pliers.

Picking it up, Li Weidong got under the tractor.

"Jingle Bell"

"Dang Dong Ding Ding"

After a while, the bottom shell of the engine was removed in amazement.

Cao Shan's expression was a little moved, as a master of the three-dismantling engine, he knew the technical difficulty.

In particular, after a long period of use, some parts of this engine have been deformed.

"Comrade Weidong, how did you do it?" Liang Ladi asked curiously, "There are a few screws that seem to be stuck inside." ”

Li Weidong raised the hammer in his hand: "Well, if you encounter a stuck screw, just knock it out." ”

Cao Shan: "."

He had the urge to drag Li Weidong out from under the tractor.

As a professional repairman, it is a shame to use a hammer, use brute force, and disassemble machinery.

Uh, Li Weidong is not a professional repairman? That's fine.

Just when Cao Shan was in a trance, Li Weidong had already removed most of the accessories.

As the owner of a 10,000-fold system, just touching the shell of the engine is equivalent to having 10,000 times of experience repairing a Ursus tractor.

It can be said that in this world, there are probably only a handful of repairmen who know more about Ursus tractors than him.

Gently touching the engine with the board and closing his eyes slightly, Li Weidong was able to tell what was wrong with the engine through the subtle vibration sound.

There are no problems with pistons, piston rings, rocker arms, valves, combustion chambers.

No, no, the combustion chamber!

Li Weidong's eyes widened suddenly, and he picked up the hammer.

Hammer, hammer, he took the hammer again! Cao Shan swallowed and foamed: "Director Li, this kind of thing is easy to damage parts, so it's better to use it sparingly." ”

"Kill it, I'll just knock it lightly."

As Li Weidong spoke, he tapped a hammer on the shell of the combustion chamber.

A slight voice came, and he closed his eyes again.

There are no problems with cylinder heads, air valves, and fuel injectors.

The sound of the pre-combustion chamber seems to be a little thick, and it should be that the wear in the cylinder is too serious.

The pre-combustion chamber is located in a small space between the intake tract and the normal combustion chamber and is used to ignite the fuel in advance.

If there is a problem with the cylinder block in the pre-combustion chamber, there is naturally no way for the engine to ignite.

"The problem was found, and it was the cylinder block in the pre-combustion chamber that went wrong."

Li Weidong got out from under the tractor, took the towel handed over by Begonia, and wiped his hands.

"Big brother in the pre-combustion room, we can't be joking." Liang Ladi looked suspicious.

Li Weidong's method of judging the fault is unheard of by Liang Ladi.

Close your eyes and listen for a moment, you can find out what is wrong, are you listening?

Besides.

The pre-combustion chamber only runs when the engine is started.

Due to the low number of starts and the short starting time, it is the part of the engine that is least likely to cause problems.

"Big brother, you're a truck driver, you can't fix this thing, it's nothing."

"Wait."

Liang Ladi was about to help Li Weidong break the siege, and Cao Shan's expression became serious.

He stretched out his large, oil-stained hand and scratched his hair with a thoughtful look: "Are you sure there's something wrong with the combustion chamber?" ”

"Specifically, it should be the inner wall of the combustion chamber." Li Weidong is full of confidence.

Cao Shan nodded heavily and pointed at Liang Ladi: "Demolish!" ”

"Huh? Master, that thing in the combustion chamber can't be broken. Liang Ladi saw that the Cao family actually accepted Li Weidong's suggestion, and hurriedly explained.

"If I ask you to demolish it, you will demolish it, don't ask so much." Cao Shan waved his hand.

In fact, in the process of disassembling the engine several times, he checked almost all the areas that were easily damaged, and found no problems.

Then it can only show one problem, this time the damage is almost impossible to damage on weekdays.

And the combustion chamber is one of them.

Seeing Cao Shan's resolute attitude, Liang Ladi threw Li Weidong a look, big brother, you are blowing up your cowhide, and my sister can't help you this time.

Liang Ladi drilled under the tractor and began to disassemble the combustion chamber.

The combustion chamber is located at the front end of the engine, and the space is cramped, making it inconvenient to operate, which is a job that is perfect for skinny lesbians.

It took her half an hour to remove the combustion chamber completely.

Carefully move it out, put it on the ground, and pick up the screws on it.

"Snap"

Open gently.

The smooth inner wall catches everyone's eye.

Hiss.

Hiss, hiss.

Hiss, hiss, hiss.

Everyone gasped in unison, and the temperature in the machine shop rose suddenly.

On the inner wall of the combustion chamber, there is a clearly visible scratch.

Apparently, this scratch was caused by a tiny, hard object flying into the combustion chamber when the engine was starting, and under the action of the cylinder.

Due to the short start-up time of the combustion chamber and the fact that there are two layers of cotton filter on the outside, the chances of this happening are slim.

Otherwise, Cao Shan would not have repeatedly let go of the combustion chamber during the inspection.

Liang Ladi covered her mouth in shock and looked at Li Weidong incredulously.

Cao Shan stretched out his palm and rubbed it on the scratch for a moment, feeling the unevenness of the surface, confirming that it was not his own illusion.

He raised his head and looked at Li Weidong incredulously: "You, how do you know that there is a scratch in here?" ”

"Guess." Li Weidong wiped his hands, clasped his hands and smiled: "You don't really think that I can hear the fault by ear, right?" ”

"That can't be? If you could hear it, you'd be a goblin. Cao Shan shook his head: "There was a meeting a while ago, and it was stipulated that after liberation, monsters are not allowed to become spirits. ”

Seeing that everyone was skeptical, Li Weidong continued to explain: "You think, Master Cao is a master, and the repair technology must be top-notch, he has disassembled it three times, but he has not found the fault part, which can only show that this fault has appeared in the most unlikely place." ”

"The combustion chamber is one of them, and I was just lucky enough to guess it."

Good luck. Cao Shan glanced at Li Weidong deeply and didn't say anything.

Being able to figure out the structure of the engine in a short period of time is not easy for this young director.

If you find a problem, it's easy to fix it.

Li Weidong also saw the strength of the ninth-level mechanic master for the first time.

Since this combustion chamber is unique, there are no spare parts in the country at all, and it can only be repaired by hand.

Cao Shan found files, hammers, coarse abrasive cloths and other tools, and squatted on the workstation and got busy.

The scratch, under his manipulation, gradually became lighter and lighter, and finally it was almost invisible.

This craft. It's time to catch up with the eighth-level fitter!

As if seeing Li Weidong's surprise, Liang Ladi explained in a whisper next to him: "Due to the lack of accessories, our mechanic is actually a kind of jack-of-all-trades, not only to learn the skills of fitters, forgings, and welders, but also to have the ability to design machinery like a first-class engineer, so that in the event of a major failure, the repair work can be completed in the shortest possible time." ”

"Master Cao once designed the take-off and landing for fighter jets"

Halfway through speaking, Liang Ladi seemed to realize that there was a suspicion of leaking, and quickly closed her mouth.

Liang Ladi's actions, looking at Li Weidong's eyes, were three hundred taels of silver here.

This woman thinks too much.

In this era, secrecy is the first priority, and the thread in everyone's mind is tight.

In order to let herself hand over the order for the production of machinery and equipment to the machinery factory, she pretended to leak secrets, which was also embarrassing for her.

Li Weidong nodded undeniably: "Master Cao's craftsmanship really doesn't have to be said. ”

Half an hour later, the repaired combustion chamber was reloaded into the engine.

Comrade Liang Ladi, the torch goddess, appeared again and put the sulfur rod into the small hole of the engine.

With Li Weidong's swaying, the tractor's engine roared, and bursts of black smoke came out of the chimney.

Cao Shan's face bloomed with joy, he walked up to Li Weidong and stretched out his hand: "Comrade, thank you!" ”

The two hands are tightly nestled together.

Li Weidong felt that Cao Shan was extra hard this time.

As the sun set, Yu Haitang reluctantly boarded Xiao Meng's jeep.

Li Weidong waved his hand and watched the jeep leave.

Liang Ladi looked at the jeep and whispered, "Big brother, Yu Haitang doesn't seem to have a shallow relationship with you?" ”

"She's my sister-in-law." Li Weidong said casually and walked to the factory.

In the evening, Li Weidong paid out of his own pocket and invited the drivers of the truck team of the machinery factory to have dinner in the small canteen of the machinery factory.

If Liang Ladi and the others can really work together to replace the leaders of the factory, then the machinery factory may be of great use to Li Weidong in the future.

In this case, it is natural to have a good relationship with the comrades of the machine factory.

"Hmph, my sister-in-law is my brother-in-law's half-pulled ass"

Liang Ladi pouted, and was about to continue, when she saw Li Weidong leaving, she hurriedly chased after her.

"Big brother, I heard that you are going to have dinner in the evening?"

"Well, with the comrades of the team."

"Can you give me one?"

"You"

"Yes, yes, I'm friends with Nan Yi, the chef of the small cafeteria."

In order to have a meal, Liang Ladi also worked hard, patted her chest and said: "You may not know that Nan Yi is the most upright, even if the factory director asks him to cook, he dares to fool him." With me here, Nan Yi will definitely be interested. ”

Looking at Liang Ladi's little greedy cat, Li Weidong almost laughed out loud and nodded: "Okay!" ”

Maybe Liang Ladi didn't brag, and Nanyige worked hard tonight.

Li Weidong actually ate the taste of palace cuisine from the plate of radish fried meat.

The old drivers in the mechanic shop hadn't tasted meat for a long time, and they almost swallowed their tongues.

"Come on, Comrade Weidong, you are really a brother, you have become a leader, and you have not forgotten your brothers, let's go one."

"Tut, don't you know, Brother Weidong, he showed a big face in the machine repair workshop today, and Cao Dana was stunned."

"Cao Dana? Is it the ninth-level master of our machine repair workshop? Tsk, that old man is arrogant. ”

"Shhhh Cao Dana is her master. ”

"It's okay, just say it, I don't mind." Liang Ladi carried the chicken leg in one hand and the duck head in the other, eating happily.

Li Weidong:

Old drivers:.

As night fell, the machine shop fell silent.

After eating and drinking, Li Weidong did not return to the guest house immediately.

Instead, take a walk along the main road of the machine factory.

Walking, walking, walked to the door of the machine shop.

The workshop emitted dim lights, and from time to time there was a trivial sound.

Who, it's so late, and you're still working overtime?

With curiosity, Li Weidong tiptoed in.

I saw Cao Shan standing in front of the workbench, measuring parts with vernier calipers.

The dim light gilded his gray hair with a golden glow.
