Rebirth of the Auto Giant

Chapter 52 Gold

Next, Wang Shi repaired the cars of the four customers promised by Lin Zhengtang.

There are cars and a Jiefang ca10 truck.

In fact, Wang Shi didn't want to repair these low-grade machines, which had little technical content and heavy engines. However, they were all state-owned units and they came from Uncle Zheng, so he had to repair them.

This is a state-owned unit of a cement factory, and the fault was a problem with the rear axle differential.

The differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right side gears, two planetary gears and a gear carrier. Its function is when the car is turning or driving on uneven roads.

When driving on the road, make the left and right wheels roll at different speeds, which ensures that the drive wheels on both sides perform pure rolling motion.

If it weren't for Zheng Wu's relationship, Wang Shi would really not want to repair this differential.

The Jiefang brand's differential is not as small and light as that of a car. The Jiefang brand's rear axle differential is a big thing, weighing several hundred kilograms, but it is difficult to lift.

Naturally, the customer's workers will cooperate with the laborious work.

When the differential is disassembled, mark the left and right differential cases and planetary gear shafts. Because the left and right bearings and adjusting screws cannot be interchanged, the assembly marks on the differential bearing caps must be carefully checked before disassembly.

.

The dismantled living king stone guided two workers on the side to start.

Two workers, one named Yang Degang and the other Chen Jianbin.

These two workers can repair cars with Master Wang, who is well-known in the capital. This opportunity is not easy to grab, and they both have some backgrounds in the company.

"This planetary gear is broken, and the shaft is also broken. I'll write a list and you can get the parts together right away." Wang Shi said, pointing to the piles of dismantled differentials.

Jiefang brand accessories are made in China and are not difficult to find. Wang Shi wrote a list and the two of them took it to the department of their work unit and asked someone to buy it.

Wang Shi took Lin Zhengtang to have lunch at the other party's factory and then went back. He would notify Wang Shi when the parts arrived.

As expected, the cement factory is a large state-owned enterprise, and it took half a day to get all the accessories.

As for assembly issues, there are also some techniques, which is to check the wear and mesh clearance of the planetary gears and side gears.

The principle is very simple. Place a soft metal wire on the joint surface of the planetary gear and the side gear, install it, and then remove it to check the thickness of the two gaskets.

This is a meticulous job.

I put a few soft metal wires on each adjustment part and then installed and removed them. I continued to adjust each gap and add or subtract gaskets. After half a day, the adjustment was finally completed.

"Did you see it? These four small conical gears are called planetary gears. During installation, the gap between them and the large side gear must be adjusted. Now let's see what the gap is." Wang Shi started dismantling the gears.

I took down two soft metal wires and measured them with a caliper.

"0.06mm is within the standard range." Wang Shi said, looking at Lin Zhengtang, "The maintenance standard for the planetary gear and side gear is 0.10mm, which generally does not exceed 0.14mm, and the wear does not exceed 0.3, otherwise

There will be problems such as loud noise, squeaking when shifting gears, and a sense of frustration when driving at low speeds. Now their gap is 0.06, which is within the normal range." Wang Shi introduced.

Lin Zhengtang took notes while listening to Wang Shi slowly say, "I understand, master."

The other two workers also listened attentively, but they did not take notes as carefully as Lin Zhengtang.

Next, Wang Shi adjusted the gaps between the side gear boss and the differential case, the backlash of the active and passive gears, and other key gears. After the obtained gaps met the standards, they were installed.

This was a monotonous process, and I had to go back and forth several times to install and disassemble it and add gaskets before I could get it right.

Putting it back together is a laborious job, and this is naturally done by the two workers from the other side. It was not easy for Wang Shi to see them just now, and he taught them a lesson. The two of them listened very carefully. As for the result, that is not Wang Shi's business.

Already.

The differential was quickly installed.

"Add gear oil. Do you see the small hole below? Just add it until it leaks out from this small hole." Wang Shi squatted down and pointed to the measuring hole in the middle and lower position of the differential and said.

"Okay, Master Wang, you go over there to rest first, and let us do the work of refueling." Two workers and Lin Zhengtang were refueling below the frame.

"Okay, thank you for your hard work." Wang Shi found a brick and sat down. Soon a female worker from a factory brought some ice cream popsicles and gave them to Wang Shi first. Then she came under the frame and gave one to each of Lin Zhengtang and the others.

.

Including the parts I just bought, it took me two days to repair the differential.

Wang Shi charged 500 yuan for the repair fee for this trip, and the other party also gave me two industrial tickets and some meat tickets.

The industrial tickets were kept, and two meat tickets were given to Lin Zhengtang with twenty yuan left. This is the usual practice.

When I returned home in the afternoon and evening, I washed my hands carefully with washing powder and sawdust to remove the black stains. The small areas between my fingernails and palm prints were not washed away, leaving small black spots and stripes.

The strips looked like mosquito coils. "Hey, I can tell at a glance that these hands are for repairs." I sighed.

At first smell, the smell of engine oil is quite strong.

Zhao Min happened to return home from get off work at the bank, and Zhao Yiming returned home not long after that. The three of them had been eating at the table.

"Won't Wang Shi invite you to watch a movie tonight?" Mother Zhao asked.

"No?" Zhao Min looked at her mother doubtfully.

"You kid, you have to take the initiative. There are not many young men with high incomes like Xiao Wang who know how to care for others. You have to take the initiative, do you understand?"

"Mom——!" Zhao Min rolled her eyes and her mother's voice sounded a little hot.

How could any girl take the initiative to invite me? It would be so embarrassing to tell anyone.

After all, I work in a bank, so it seems like no one wants me.

"Silly girl, Mom has been here before. This good man is like gold buried in the sand. Sooner or later he has to shine. All you have to do is grab this piece of gold in your hand before others find it, otherwise it will be stolen from you.

Someone was snatched away from you." Mother Zhao gave her daughter a white look.

"So my dad was also the piece of gold in the sand back then?" Zhao Min said, looking at his father.

"Well, look at your father now. Isn't he gold? It proves that your mother's vision is not wrong. Hold your father tightly in her hand before others find out."

"Come on, the more you talk, the more outrageous you are." Why did you keep talking about me?

Zhao Yiming heard two guns pointed at him to stop him and said, "Don't tell me, you and I were indeed talented people back then."

"As the old saying goes, women are afraid of marrying the wrong person, and men are afraid of getting into the wrong profession. If you have found the right partner, you can't let go. Otherwise, you will regret it for the rest of your life. You are still young and don't know this. Mom is here, so listen to her." Mother Zhao

While eating, he taught his daughter a lesson.

"Mom——, you asked me, a girl, to take the initiative to invite others. I can't do it. It's embarrassing." That bastard does meet the standards of this girl, but I can't let myself be embarrassed and invite others. I make myself look like

It's like I won't marry him unless I do.

"You, you, this girl is chasing after a man, and a man is chasing after a girl. She is absolutely right. My daughter is so beautiful, kind-hearted, and good at work. She is so beautiful. As long as you can let go and take the initiative.

No man can refuse his pursuit," Zhao's mother said.

"Well, what your mother said makes sense. I think that boy is just a dull guy who only knows about work. If you want him to take the initiative to invite you on a date, I think he won't even do it once when you are old. So, you

If you are interested in that kid, it is better to take the initiative. I have been with him for more than a week and I know his personality best. I will be very happy if you two finally get together." Zhao Yiming said.

"Look, if you don't listen to me, you can't help but listen to your father, right?"

"Look at you two, it's like this. It seems like your daughter can't marry anyone other than Wang Shi." Zhao Min couldn't bear what her parents said.
