"Hello, I am Li Wenkai from Hongxing Machinery Factory. These two are my apprentices." Li Wenkai stretched out his hand and said to a man in his fifties.

The middle-aged man is named Wang Guofu, and he looks more honest and honest.

The other party is the leader of the unit's transportation team support team, and there are several subordinates under his command.

"It turned out to be from a brother's unit. I have heard that Hongxing Machinery Factory has a master Li with superb maintenance skills. He can repair imported high-end cars such as Volga 3 and Mercedes-Benz. Now he has finally seen his true body." The other party was talking about the real body, not the real person.

"I'm too proud, I'm not that lucky." Li Wenkai knew that the fact that he had repaired two cars in a row has spread in the industry.

"Luck is also part of ability, Master Li should not be humble anymore." Wang Guofu looked at Li Wenkai and said, then looked at his subordinates with a look of regret and said: "Master Li helps see what the problem is, we have checked the carburetor, air filter element, distributor, and ignition coil. They are all normal. We probably have a problem in the engine. Master Li takes a look." Wang Guofu said.

Wang Guofu said this to tell Li Wenkai that they didn’t know anything and also told Li Wenkai that they had done a lot of work.

The car is now in trouble, and the unit leaders are also concerned.

Now is the busiest time of the quilt factory. There is a problem with the only two trucks, which has delayed much work. Therefore, the leaders are very dissatisfied with the support staff of their transportation team.

After Master Li has repaired it, the leader may come over to ask. If he asks, I hope Li Wenkai can help them with "a few good words".

"Well, I'll take a look again. It may be a problem in the engine. Do you still have to take a look?"

After both parties were polite, Li Wenkai checked the lines, batteries, engines, high-voltage coils, platinum contacts of the distributors according to the "from outside to inside" rule.

Finally checked the starter.

The Jiefang Ca10b is equipped with a starter, and the front end of the crankshaft pulley is also equipped with a hand-crank interface, which is combined with manual and electric.

Li Wenkai checked the peripheral components and knew the problem in his heart.

Seeing Li Wenkai's confident expression, Wang Guofu asked with concern: "Master Li, what a sudden look?"

Li Wenkai looked at everyone and said, "I can deal with this problem, but..." Li Wenkai did not say anything further.

Everyone knew it well, and Wang Guofu said, "We all understand that we won't let Master Li do it for nothing, but I hope Master Li will charge a little less, we don't have $50." After that, everyone laughed.

"Where are those who kill foreigners? We are our own people, not much, just 25 yuan." It has been reduced by four times.

This is a day's work, of course, when the accessories are in place.

"Okay, this is not high, I'll ask the leaders above to ask them immediately." Wang Guofu said, and then sent his men to say hello to them.

"Okay." Li Wenkai looked around, Zhou Aiguo came over with a stool, and Li Wenkai sat down.

Zhou Aiguo and Shen Zhengjun stood behind Li Wenkai.

Soon, the other party came back and said that he had agreed to the conditions proposed by Li Wenkai.

"Master." Shen Zhengjun proposed to count the money and remind Li Wenkai whether to collect the money first.

"No, that's to outsiders, you don't have to be so heartless." Li Wenkai said, and then the three of them began to change into old dirty clothes and prepare to start.

"Everyone, we have started working, so, everyone, hehe..." Shen Zhengjun began to drive people away.

In his heart, the master's "unique skills" can only let the two of their apprentices know that outsiders cannot be present to learn skills.

Everyone knew it well. They thought they could watch it on the spot. After all, they had done a lot of work before, and they were just about to stop. They also wanted to see what the problem was. Unexpectedly, Shen Zhengjun said it. Now everyone was embarrassed to stay anymore, so they could only leave the scene with regret.

Li Wenkai was embarrassed to say this. This evil man could only let Shen Zhengjun do it. After everyone left, Shen Zhengjun closed the door of the repair workshop, "Master, it's done."

"Senior brother, this." Zhou Aiguo gave Shen Zhengjun a thumbs up.

"That's natural. I'm the eldest brother. It's my responsibility to protect the unique skills of the masters." Shen Zhengjun said.

"Don't talk nonsense, work quickly." Li Wenkai said.

Zhou Aiguo brought the tools over.

Li Wenkai just checked this engine, which was mainly due to the problem inside. It is estimated that the piston ring and cylinder liner were worn too much, resulting in insufficient cylinder pressure in the combustion chamber.

Now there is no problem with the inspection outside, so now you have to start turning on the engine.

"This is a very rare opportunity. You have read the book "Engineering Machinery Construction and Principles" I gave you. Now we are combining practice. This time I will disassemble the engine. You must be clear about the name and function of each part." Li Wenkai bought a book "Engineering Machinery Construction and Principles" for his apprentices from Hyundai, and now the two have learned a lot.

From the question asked in the evening, Li Wenkai knew the learning progress of his two apprentices. Although he had not learned some things, he started to do it now. When the time comes, he would be more impressed and more understanding.

Car maintenance is a profession with strong hands-on ability. No matter how strong your theory is, it will be useless if you don’t have the ability to move.

He removed the electronic parts, starter, engine, oil core, air core, carburetor, etc. from the outside. During the process, Li Wenkai also took two apprentices to take notes if he didn't know.

Li Wenkai taught while dismantling. Because it was on-site teaching, the progress was much slower. It was not until noon that the cylinder head was removed and the engine oil was also released.

"Look at the engine oil, take a closer look at the black metal powder under the oil pan. This is ground down from the cylinder liner, piston ring and tiles. So much metal powder has been grounded away. The wear of the cylinder liner and piston ring must be huge. If the gap is too large, the pressure inside will be small. This is the reason for this failure." Li Wenkai pointed to the oil pan while dismantling it, pointing to a layer of ferrous metal powder attached to the oil pan to introduce it.

The two knew that such an opportunity was rare and listened very seriously.

Li Wenkai knew that Zhou Aiguo learned faster and now he learned the piston connecting rod group, so he took the test of Zhou Aiguo's composition and role in the piston connecting rod group.

Zhou Aiguo can also answer.

"Yes, theory is a teacher of practice. If you don't know theory, you can only cross the river by feeling the stones. If you have theory as your guide, practice will be fast. Shen Zhengjun, you have to learn from your junior brother." Li Wenkai looked at Shen Zhengjun and said.

"Master, I'm not bad either. I just don't have time to study during the day. Shibei is idle at home, so the progress is faster than mine." Shen Zhengjun said.

Li Wenkai knew that Zhou Aiguo had been staying for three days due to brain injury, and all these three days were spent on learning.

The air distribution mechanism of this old engine is different from the top cam wheel decades later. The pushing cup and pushing column of the engine's air distribution mechanism are side-mounted and driven by the camshaft inside the engine body.

"Master Li, it's here at noon. Let's have a simple meal first and then do it." Wang Guofu shouted outside.

"Okay, don't move things, eat first," Li Wenkai clapped his hands and said.
