Rebirth of the Auto Giant

"Among the three, only when the cylinder head gasket is damaged can water enter the combustion chamber. Only when the combustion chamber is filled with water, the liquid is incompressible, causing the crankshaft to be unable to rotate..." Duan Luanhong analyzed.

Once you figure out the logic, the rest is proof.

"Here, take off this cover..." Just do it as soon as you think of it. First, clean the oil engine. Duan Luanhong and Guo Yuquan removed the engine cover together, and then removed the intake and exhaust manifolds... Then

It's the rocker arm assembly...

"I hope my guess is right." When the two began to loosen the cylinder head screws, Duan Luanhong became nervous.

You will know soon whether it is right or not.

Although Guo Yuquan is usually loud-mouthed, he has very strong hands-on skills. In addition, the two of them have worked in every position in the engine assembly workshop. They are very skilled in these disassembly tasks.

Remove the cylinder head screws and lift the cylinder head together.

"Oh, it's all water." Guo Yuquan exclaimed when he saw the "watery area" inside the combustion chamber. "Brother, is this a problem with the cylinder head gasket?" Guo Yuquan saw the situation in front of him and immediately thought of it.

The key point.

"Yeah." Duan Luanhong nodded.

Once the problem is found, it will be easier to solve.

The mental arithmetic that the two of them had been talking about fell down.

Trouble diagnosis is currently a difficult point for both of them. If the problem is found, then installation and disassembly will not be a problem.

The two of them were very skilled at installation. As for the installation of cylinder heads, the two of them had assembled countless cylinder heads in the engine installation workshop.

The two of them removed the cylinder head. Guo Yuquan was responsible for cleaning the cylinder head and scraping the gaskets of the intake and exhaust branch pipes. Finally, in order to better clean the oil pan, he simply removed the oil pan as well.

Duan Luanhong asked someone to find a sponge to suck up the water in the combustion chamber, and finally cleaned it with diesel fuel, and then shoveled clean the cylinder head gasket where the engine body was in contact with the cylinder head.

"It's too late, two masters, how about we do it tomorrow?" the person in charge of the battlefield said in the past.

"Ah, it's so fast." Duan Luanhong stood up and found that the lights were already bright, and the battlefield was also lit with electric lights.

Duan Luanhong asked someone to find a clean cloth to block the combustion chamber, "Okay, let's find a raincloth to cover the engine."

"Hurry up, get a few people and put the raincloth on the engine hood." The person in charge of the battlefield shouted loudly, and two young men walked out holding the raincloth.

Duan Luanhong and Guo Yuquan kept the engine cover closed and moved the removed accessories of the intake and exhaust manifolds into the house.

The two asked someone to find washing powder, washed their hands with sand, and then got into each other's car and arrived at the guest house of the other company.

"Is there any long-distance call? I'll call the work unit first and ask them to send the parts first and repair the engine as soon as possible." Duan Luanhong asked.

"Okay, I'll take you there." After the other party brought two people to the company to explain, Wang Shi thought for a while. It was already off duty in the unit and there was no one in the office. He thought of the factory director's eldest brother's mobile phone, so he called

passed.

"The problem has been found, it is..." Duan Luanhong simply told Wang Shi, and then said: "Mr. Wang, tomorrow I will ask my family to send an overhaul kit, as well as a special torque wrench and valve feeler gauge.

Come here..." Duan Luanhong nervously mentioned the accessories he needed.

Wang Shi was a car repairman and knew what parts were used, so he nodded in agreement.

This time, the problem is mainly caused by the cylinder head gasket. There are no problems with the piston and cylinder liner, and only an engine overhaul kit can solve it.

The engine overhaul kit includes cylinder head gasket, oil pan gasket, intake and exhaust manifold gaskets, etc.

The cylinder head screws are special screws, and the tightening torque has strict regulations. It will not work if it is too tight, and it will not work if it is loose. You must use a special torque wrench to tighten it three times in a strict sequence.

In the past, these torques were tightened in the workshop using special power tools developed by Tang Dynasty Power Company and two engineering universities for the production line, but now they have to be tightened manually in the field.

The two of them also knew very well how many kilograms of force were exerted on the screw.

"Okay, I get it, you guys do your best." Wang Shi didn't expect that the two of them could find the fault so quickly, and they were satisfied.

The other party led the two of them to a private room. The food was already laid out and was very rich. There was a bottle of Maotai on the table.

"Come on, you two masters have worked hard. Let's fill our stomachs first, and then we'll drink." After the person in charge finished speaking, he shouted out the door: "Let's get some food!"

Soon a young waitress came in carrying a bowl of rice.

"Thank you, Master Chen, for your hospitality. You're welcome." Duan Luanhong said. The two of them came here today because they had something on their minds and didn't eat much. They were very hungry after a busy day.

The waiter on one side served a bowl of rice to the three of them.

The three of them ate hungrily.

The other party has never eaten the food here, so the company can only allow Duan Luanhong and other factory masters to come, otherwise the company will allow him to eat and sleep in the guest house. Otherwise, even the person in front of him will not come as soon as he says he can.

After eating three bowls of rice in a row, he slowed down and started drinking.

"Masters, when will the engine be ready?" the other party asked with concern.

"I don't know about this yet, but you also know that I just called our factory director and will send the necessary accessories tomorrow. When will they arrive and when will they be done? In fact, the installation does not take much time, just one or two

Hours are enough." Duan Luanhong had a short talk with the other party.

"The person you called just now was your company director Wang Shi?" Now Wang Shi is also a famous figure in the country. The other party did not expect that in a company with 50,000 employees like Tang Dynasty Company, a small low-level employee would dare to call the factory director.

Call up.

"Yes, at this time, the unit has already got off work and there is no one in the office. I will call our factory director's brother. Our factory director will arrange for someone from the parts department to send the parts after he gets to work tomorrow."

"Then it will take at least two days to arrive." It takes at least two days to get from Beijing to Luoyang.

"If you want to go faster, you should send someone to wait at Zhengzhou Railway Station the day after tomorrow and pick up the goods directly then. Otherwise, it may be delayed for a day or more until it is shipped to Luoyang." Guo Yuquan said.

"My junior brother is right. This is the only way we can do it quickly. There is nothing we can do." Duan Luanhong nodded and said.

"Okay, I'll tell the leader tomorrow and ask him to send someone to the train station to pick up the goods directly."

The three of them were eating and singing, "The two masters have been resting in the guest house these days, and also used this time to take a walk," the other party said.

While waiting for accessories for two days, Duan Luanhong and Guo Yuquan had a good time in Luoyang.

At noon on the third day, the parts finally arrived. The two knew that the parts would arrive today and did not go out to play. They came to the site with the parts and started installing the engine.

Duan Luanhong took out the special torque wrench that was sent to him.

This was sent by Wang Shi from Germany.

Now the German Manman Company has business relations with the Tang Dynasty Company, and special tools like these can also be sent over.

This was specially equipped by Wang Shi for the service department, and a total of twenty were imported.

The wrench is made of stainless steel, and the torque can be adjusted at any time. When the torque exceeds the set torque, it will automatically slip when it is overloaded and will make a clicking sound, making the torque more accurate.

The two of them were very familiar with the installation. Everything was done according to the standard operating procedures. In about an hour, the parts that had been disassembled were put back together without even touching the ground, and not even a single screw was left behind.

"I really have to admire this skill. I really can't believe that the two of them are so good at such a young age."

"Yes, I'm really envious. With this skill, I don't have to worry about not having enough to eat, even if I get laid off."

Everyone gathered around to watch Duan Luanhong and the two working in an orderly manner.

The last two worked together to adjust the valve clearance, put on the valve cover, and after checking that everything was fine, added engine oil and filled the water tank with water.

Finally, check the diesel pipeline and drain the air from the low-pressure diesel pipeline.

"Master, go up and start the engine. Stop when I tell you to."

"Okay." As soon as the driver heard that he could start the engine, he was ready. He happily came to the cab to start the car. After Duan Luanhong drained the air from the high-pressure pipeline of the diesel pipeline, he pressed the fuel pump and heard a hiss.

After the backflow valve makes a hissing sound, tighten the oil transfer pump.

After Duan Luanhong finally checked that there was nothing left and right, he said to the master in the cab: "Okay, you start it."

"Beep..." The four-cylinder engine roared, and a puff of black smoke came out of the muffler. After the car was warmed up, the exhaust gas color returned to normal.

"Okay, okay, it's so fast. I've seen a repair and liberation project in the past, but it's been two days and it still hasn't been completed."

"Can it be the same? I am a master of Tang Dynasty Power Company and a regular army. How can those guerrilla generals outside compare with me?"

"Junior brother, go up and see if the oil pressure, water temperature and other gauges are normal." Duan Luanhong said while sitting on the high wheel of the loader.
