Siheyuan: Start with a big car

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

Cao Shan was wiping his hands with a towel, his hands trembled unconsciously, and there was an extra smear of oil 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 repair work.

It's just that the three-legged kung fu of the truck driver is simply useless here.

Out of politeness, Cao Shan didn't say anything, but kept blinking at Xiaomeng.

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

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 is no blueprint, I have to figure it out by myself, it's not that my sister can't trust you, it's just..."

In the middle of speaking, Liang Ladi felt that something was wrong, so she quickly closed her mouth.

sister?Yu Haitang glanced at Liang Ladi suspiciously, and thought to herself, this woman is really not serious.

Li Weidong put his hands together and smiled calmly.

"Of course, I haven't seen this kind of tractor before, so I'm not sure. However, even if I disassemble the engine, there is no way to restore it. Isn't there still Master Cao?"

"Currently, Master Cao has no way to find out what's wrong. It may be a problem of thinking. If there is another person, maybe there will be a new thinking."

"You think my idea is right?"

Although Cao Shan felt that Li Weidong looked down on the profession of mechanics, he had to admit that Li Weidong's thinking was reasonable.

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

An obvious mistake, often checked several times, but still can't find it, is the blind spot of thinking.

Cao Shan nodded lightly: "Since Director Li is interested, it would be unreasonable for me to refuse."

"However, there are regulations in our machine repair workshop, and the repair work must be done by yourself."

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

Liang Ladi looked at Cao Shan in surprise.

This kind of regulation was originally intended to prevent apprentices from making noise by the side.

Now that Cao Shan raised it, it seemed a bit embarrassing for Li Weidong.

Liang Ladi didn't realize that, in 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 road is flat, but the effect is relatively slow.

The path is rough, but it can reach the soul directly.

Xiao Meng also woke up at this time.

Seeing Li Weidong's resolute attitude, he smiled and said, "Director Li is also an old driver, and he knows this rule."

With that said, he took the initiative to help Li Weidong bring tools such as wrenches and pliers.

After taking it, Li Weidong got under the tractor.

"ding ding dong"

"Ding Ding Ding Ding Ding"

After a while of operation, the bottom case of the engine was removed under the surprised eyes of everyone.

Cao Shan's expression was a little moved. As a master craftsman who disassembled the engine, he knew the technical difficulty.

Especially this kind of engine has been used for a long time, and some parts have been deformed.

"Comrade Wei Dong, how did you do it?" Liang Ladi asked curiously, "A few screws seem to be stuck inside."

Li Weidong raised the hammer on his hand: "Here, 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 take apart machinery.

Uh, isn't Li Weidong a professional repairman?That's fine.

While Cao Shan was in a trance, Li Weidong had already removed more than half of the accessories.

As the owner of a ten thousand times system, just by touching the casing of the engine, he has the experience of repairing the Ursus tractor ten thousand times.

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 slight vibration.

Pistons, piston rings, rocker arms, valves, combustion chambers are all fine.

No, no, combustion chamber!

Li Weidong suddenly widened his eyes and picked up the hammer.
Hammer, hammer, he's got a hammer again!Cao Shan swallowed and spit: "Director Li, things like hammers are easy to damage parts, so it's better to use them sparingly."

"To kill things, I just tap lightly."

Li Weidong was speaking, and tapped lightly on the casing of the combustion chamber with a hammer.

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

There is no problem with the cylinder head, air valve and fuel injector.

The sound of the pre-combustion chamber seems to be a bit thick, which should be due to the severe wear and tear in the cylinder body.

The pre-chamber is located in the small space between the intake port 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, the engine will naturally have no way to ignite.

"The problem has been found. It is the cylinder block in the pre-combustion chamber that has a problem."

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

"Brother pre-chamber, we can't joke around." Liang Ladi looked suspicious.

Li Weidong's method of judging faults is something Liang Ladi has never heard of.

Close your eyes and listen for a moment, you can find out the fault, are you listening?
Moreover.

The pre-chamber only operates when the engine is started.

Due to the low number of starts and the short start time, it is the least likely part of the engine to have problems.

"Big brother, you're a truck driver, it's okay if you can't fix this thing."

"and many more."

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

He stretched out his big oily hand and scratched his hair, looking thoughtful: "Are you sure there is something wrong with the combustion chamber?"

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

Cao Shan nodded heavily, pointing to Liang Ladi: "Demolish!"

"Ah? Master, that thing in the combustion chamber can't be broken." Seeing that Cao Shi accepted Li Weidong's suggestion, Liang Ladi quickly explained.

"I told you to dismantle it, so you dismantle it, don't ask so many questions." Cao Shan waved his hand.

In fact, during the dismantling of the engine several times, he checked almost all the easily damaged places, and found no problems.

Then it can only explain one problem, the damage this time is a place that is almost impossible to damage on weekdays.

And the combustion chamber is one of them.

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

Liang Ladi got 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. This kind of work is very suitable for thin and small lesbians.

Even so, it took her half an hour to completely remove the combustion chamber.

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

"pat"

Gently open.

The smooth inner wall caught everyone's eyes.

hiss.

Hiss, hiss.

Hiss, hiss, hiss.

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

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

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

Due to the short start time of the combustion chamber and the two layers of filter cotton on the outside, the chances of this happening are extremely small.

Otherwise, Cao Shan wouldn't have missed the combustion chamber repeatedly during inspections.

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

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

He raised his head and looked at Li Weidong in disbelief: "You, how do you know there is a scratch in it?"

"Guess." Li Weidong wiped his hands dry, put his hands in his arms and said with a smile, "You don't really think I can hear the fault with my ears, do you?"

"That can't be done? If you can hear it, you will become 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 dubious, Li Weidong continued to explain: "You think, Master Cao is a master, and his repair skills must be top-notch. He has disassembled it three times, but he has not found the fault location. Impossible place."

"The combustion chamber is one of them. I just got lucky and guessed it right."

Good luck. Cao Shan took a deep look at Li Weidong and didn't say much.

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

Once the problem is found, it's easy to fix.

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

Since this combustion chamber is unique, there are no spare parts in China, so it can only be repaired by hand.

Cao Shan found tools such as files, hammers, and coarse sand cloth, and squatted at his work station to get busy.

The scratch, under his operation, gradually became shallower, and finally it was almost invisible.

This craftsmanship can catch up with the eighth-level fitter!

As if seeing Li Weidong's surprise, Liang Ladi explained in a low voice beside him: "Because of the lack of accessories, our mechanics are actually a jack-of-all-trades job. In that way, we have the ability to design machinery, so that we can complete the repair work in the shortest time when encountering major failures.”

"Master Cao once designed takeoffs and landings for fighter jets"

In the middle of speaking, Liang Ladi seemed to realize that there was a suspicion of leaking secrets, so she quickly shut her mouth.

Looking at Li Weidong's eyes from Liang Ladi's actions, there is no silver 300 taels here.

This woman is too careful.

In this day and age, secrecy is the top priority, and the thread in everyone's mind is tense.

In order to let her hand over the order for the production of machinery and equipment to the machinery factory, she even pretended to leak the secret, which was really embarrassing for her.

Li Weidong nodded irrefutably: "Master Cao's craftsmanship is really worth mentioning."

Half an hour later, the repaired combustion chamber was reinstalled in the engine.

Comrade Liang Ladi, goddess of torches, appeared again, sticking a sulfur rod into the small hole of the engine.

Accompanied by Li Weidong's violent shaking, the tractor's engine roared, and black smoke came out of the chimney.

Cao Shan's face was full of 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 working extra hard this time.

As the sun was setting, Yu Haitang reluctantly boarded the jeep driven by Xiao Meng.

Li Weidong waved his hands and watched the jeep leave.

Liang Ladi looked at the jeep and whispered, "Big brother, it seems that Yu Haitang has a good relationship with you?"

"She's my sister-in-law." Li Weidong said casually, then walked into the factory.

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

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

Under such circumstances, it is natural to establish a good relationship with the comrades in the machinery factory.

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

Liang Ladi pursed her lips, and was about to continue speaking, when she saw Li Weidong leave, she hurried to catch up.

"Big brother, I heard that you are going to have dinner tonight?"

"Well, with the comrades in the team."

"Can you take me one?"

"you"

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

In order to have a meal, Liang Ladi also desperately patted her chest and said: "You may not know that Nanyi is the most noble person. Even if the factory manager asked him to cook, he would dare to fool him. With me here , Nanyi will definitely take care of it."

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

Maybe Liang Ladi wasn't bragging, Nanyi worked extra hard tonight.

Li Weidong actually tasted like court food from the plate of radish fried meat.

Those old drivers in the machine repair factory haven'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."

"Tsk tsk, you don't know, Brother Weidong, he showed his face in the machine repair workshop today, and Cao Dana was taken aback for a while."

"Cao Dana? The ninth-level master in our machine repair workshop? Tsk tsk, that old man is so proud."

"Hush, keep your voice down, Liang Ladi is here! Cao Dana is her master."

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

Li Weidong:
Veteran drivers: .
As night fell, the machinery factory fell into silence.

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

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

Walking, walking, to the door of the machine repair workshop.

Dim lights emanated from the workshop, and there was a trifling sound from time to time.

Who, it's so late, still working overtime?

With curiosity, Li Weidong tiptoed in.

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

The dim light cast a layer of golden light on his gray hair.
