Chapter 353 Solution

Author: Xiangdongxiangdong

"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 oil 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 are a truck driver before, you can do some repairs.

However, the truck driver's three-legged cat skills are of no use here.

Out of politeness, Cao Shan did not say anything, but kept blinking at Xiao Meng.

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

The first person to react was Liang Ladi.

She swallowed her saliva, walked over and said with a smile: "Brother, this is a foreign tractor. There are no drawings. I have to figure it out by myself. It's not that I can't trust you, it's just..."

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

Sister Yu Haitang glanced at Liang Ladi suspiciously and said to herself, this woman is indeed not serious.

Li Weidong clasped his hands and smiled calmly.

"Of course, I have never seen this kind of tractor, and I am not sure. However, even if I disassemble the engine and there is no way to restore it, isn't it because Master Cao still has it?"

"Master Cao can't find the problem for the time being. It may be a problem with his thinking. If he changes to another person, he might have new ideas."

"Do you think my idea is right?"

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

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

An obvious mistake, even though I checked it several times and still couldn't find it, it was caused by a blind spot in my thinking.

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

"However, our machine repair shop has regulations, and repair work must be done by yourself."

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

Liang Ladi glanced at Cao Shan in surprise.

This kind of regulation was originally intended to prevent apprentices from being too ambitious and making random noises around them.

Now that Cao Shan has brought it up, it seems to be 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 roads through a woman's soul, one is the main road and the other is the small road.

The road is smooth, but the results are slow.

The trail is rugged, but it leads straight to the soul.

Xiao Meng also woke up at this time.

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

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

After taking it, Li Weidong got under the tractor.

"ding-ding-ding-ding-ding"

"Dang Ding Ding Ding"

After a while of operation, the bottom case of the engine was removed in front of everyone's surprised eyes.

Cao Shan looked a little moved. As a master of three disassembly engines, he knew the technical difficulty involved.

Especially after long-term use of this kind of engine, some parts have been deformed.

"Comrade Weidong, 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 hammers and brute force to dismantle machinery.

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

While Cao Shan was in a daze, Li Weidong had already removed most of the accessories.

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

It can be said that there are probably only a handful of repairmen in the world who know Ursus tractors better than he does.

Touching the engine lightly with the board and closing his eyes slightly, Li Weidong was able to tell what was wrong with the engine through the subtle vibrations.

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

No, no, combustion chamber!

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

Hammer, hammer, he took the hammer again! Cao Shan swallowed and spat: "Director Li, hammers can easily damage parts, so it's better to use them sparingly."

"To clear things up, I just give it a light tap."

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

A slight sound came and he closed his eyes again.

There are no problems with the cylinder head, valves, and fuel injectors.

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

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

If there is a problem with the cylinder in the pre-combustion chamber, the engine will naturally be unable to ignite.

"The problem has been found. There is something wrong with the cylinder in the pre-combustion chamber."

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

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

Li Weidong's method of determining faults was something Liang Ladi had never heard of.

Just close your eyes and listen for a moment, and you will be able to find out where the fault is. Are you listening?

Moreover.

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

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

"Brother, you are a truck driver. If you can't repair this thing, it doesn't matter."

"etc."

Liang Ladi was about to help Li Weidong rescue the siege, when Cao Shan looked 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 confident.

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

"Ah? Master, that thing in the combustion chamber cannot be broken." Liang Ladi quickly explained when she saw that Cao had accepted Li Weidong's suggestion.

"If I ask you to take it apart, just do it. Don't ask so many questions." Cao Shan waved his hand.

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

So this can only explain one problem. What was damaged this time is a place that is almost impossible to damage in normal times.

And the combustion chamber is one of them.

Seeing Cao Shan's resolute attitude, Liang Ladi gave Li Weidong a look, "Brother, you are too boastful, and I can't help you this time."

Liang Ladi got under the tractor and started to disassemble the combustion chamber.

The combustion chamber is located at the front end of the engine, and the space is tight, making it inconvenient to operate. This kind of work is very suitable for thin lesbians.

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

Carefully move it out, place it on the ground, pick up the box and unscrew the screws on it.

"Click"

Open gently.

The smooth inner wall catches everyone’s eyes.
