Chapter 13, Passenger bus lying in bed
The sky is clearing, today is a warm winter day, very good weather.
Chen Guohua is carrying a military green backpack full of period characteristics.
This is an employee benefit issued by the Mentougou Coal Mine, and was awarded to Lao Chen.
The backpack contains a lot of fried dried radish and sauerkraut, which are the most common vegetables in winter.
"Okay, you all go back and have a rest. Remember to ask your neighbors for help if you need anything, do you hear me?"
The three sisters stood at the door, looking at him eagerly.
After admonishing them, Chen Guohua turned around and embarked on the road to study.
The distance from Mentougou to Beijing No. 65 Middle School is about 32 kilometers, which is not that close.
Walking to school was impossible, the only option was to take a car.
There are five major mining areas in Mentougou, and the transportation is quite convenient.
Following the country road leading out of Majiafen, we soon reached the main road.
Chen Guohua waited on the main road for more than 20 minutes, and finally a passenger bus came.
Before getting in the car, Chen Guohua quickly learned the origin of the car through the biological hard drive.
This is the Ikarus bus. This car is incredible.
Because this car is 70 meters long and can carry [-] passengers.
At that time, we exchanged food for 76 vehicles in one go, but it was the time of the Northern War and the economy was very tight.
Therefore, it can be said that people all over the country tightened their belts and saved food between their teeth in exchange for Hungary.
After getting on the bus, Chen Guohua announced his destination and handed over [-] cents from his pocket.
The conductor gave him two tickets directly, one for ten cents and one for five cents.
To be honest, [-] cents for a bus ride is still very expensive in this day and age.
But, this is necessary.
A distance of more than 30 kilometers is not a short distance.
Even if it is a bus, with such detours and frequent stops, it will take at least two hours to reach the destination.
There were not many passengers on the bus, about half of the seats were occupied.
But you guys carry quite a lot of luggage.
Chen Guohua was sitting near the car door. This position had a good view, and he could detect any danger immediately.
Of course, the speed of this car is only thirty or forty yards.
Even if there is danger, it is very limited.
The car was driving on the road unsteadily, but halfway, something broke down.
The driver got out of the car to check and perform maintenance.
Drivers in this era are both drivers and maintenance workers, so they are considered all-rounders.
There is no roadside assistance or garages these days.
If the car breaks down, it is the driver who repairs it himself.
As a result, after the driver fiddled with it for about ten minutes, he asked everyone to get off the bus and take the next bus to the city.
In an instant, everyone exploded.
Next bus? Then we have to wait an hour or two? Many passengers who were going to the city to see a doctor, or work or study, stopped working.
"It's useless for you to urge me. The wheels on the back of this car are broken. I can't continue driving at all. I have to replace the wheels."
The driver pointed at the wheels behind and said helplessly.
Chen Guohua and other passengers all got off the bus and saw the situation.
One of the middle-aged men, Liang Dadong, said:
"Master, don't you need to change the wheel? Just add a new rubber ring to seal it."
"Who are you?" the driver asked strangely.
Liang Dadong introduced himself as a worker in the Beijing Machinery Repair Factory.
"Isn't that in Changping? Why did you come to Mentougou?" The driver's vigilance was not as high as usual.
This bus is a suburban bus from Mentougou to the center of Beijing. However, Changping is in the north, completely opposite!
"I came to Mentougou on business to repair machinery."
After a while, after Liang Dadong took out his work permit, the driver believed what he said.
But there was still no progress in repairing the car's rear wheels.
Because the driver has no such thing as a rubber ring.
The capital city of this period lacked everything.
Things like rubber rings can only be imported, and there is no other way.
"Isn't there anything else that can replace the rubber ring?"
While Liang Dadong was discussing with the driver, an intellectual wearing glasses next to him raised his doubts.
Almost all the people in the bus got off the bus, and everyone was surrounding the bus to check it out.
People who wear glasses are considered by everyone to be smart, knowledgeable people and worthy of respect.
"Of course, the rubber ring can act as a seal to prevent lubricating oil from flowing into the brake drum."
Liang Dadong's words immediately left the intellectual wearing glasses speechless.
At this moment, Chen Guohua suddenly said: "We can actually use Scotch tape to solve this problem."
His words immediately aroused opposition from the driver, Liang Dadong and intellectuals.
Everyone thinks that Chen Guohua is a young man and should not talk nonsense if he doesn’t understand.
Intellectuals, in particular, had the loudest opposition.
When facing the two professionals, the driver and Liang Dadong, the intellectual could not use his brain.
After all, repairing the car touched upon his blind spot of knowledge and could not solve the problem.
But Chen Guohua is just a "little kid" who dares to talk nonsense, so of course he will be reprimanded.
Faced with doubts, Chen Guohua smiled.
Based on the paper on the Ikarus bus maintenance experience in the biological hard drive in his brain, he said with a slight smile:
"The lubrication of the reducer gear and the inner and outer bearings of the wheel hub of Ikarus buses uses hyperbola gear oil, which is sealed by the oil seal at the inner end of the wheel hub and the rubber ring on the outer end cover of the reducer."
"In other words, the inner oil seal is actually made of rubber and metal skeleton."
"This kind of oil leakage is basically caused by the inner oil seal falling off and the lip being severely worn."
"Comrade driver, our car is often overloaded, right?"
After saying this, the driver and others all looked at Chen Guohua blankly.
The only people who could understand him were Liang Dadong and the driver.
As for intellectuals and others, they just listen to what is written in heaven.
Although they are all in Mandarin, when combined together, I don’t know what they mean.
"That's right, when we get to Fushi Road, there will be more people."
The driver responded quickly. Chen Guohua nodded and continued: "That's right. It's been more than seven years since this car was imported in [-]."
"It's absolutely normal for the rear wheel to have such a situation."
"The oil seal falls off mainly because the outer diameter of the oil seal is too loosely matched with the bearing hole, or it is not aligned with the inner journal during installation."
"The solution is also very simple."
At this point, Chen Guohua's mouth felt a little dry and he paused.
As a result, Liang Dadong became anxious and asked: "Comrade, please tell me quickly. What's the simple way?"
"Oh, you still drink water, you are really anxious."
puff!
The conductor couldn't help laughing, and so did the other passengers.
"Oh my god, my mouth is dry, what's the matter with some water?"
