In 1992, a small village owner became the richest man in the village by owning a car.

Chapter 208 Installing and testing a Bomag BW160 road roller!

Han Jingfan saw innocence in the other person's eyes and couldn't help but sigh. How terrible must this child's past environment have been to cultivate such values?

“Ah Gui, a real mechanic is not just someone who fixes a car, makes it run and move, and then the bosses are happy and give you money, and that’s the end of it.” Han Jingfan then picked up a chopstick from the side.

“This chopstick is like the Xiali car you repaired this morning. You fixed it, and you still have several engine screws left. But how far do you think it can go? How many days can it last?” Han Jingfan looked at him. “Imagine that your parents, your mentor, me, or even yourself are sitting in the car.”

"And just because you didn't install those few screws, bang!" Han Jingfan snapped the chopsticks in half. "The car was wrecked, and everyone was dead. Agui, would you want to see your parents, or your master, killed because you missed a few screws?"

Han Jingfan's words were a bit harsh, but this child was already thirteen years old, and fourteen by the New Year. He already had simple logical principles in his mind. If she didn't take strong measures now, it would probably be even more difficult for him to correct his behavior later.

Upon hearing this, A-Gui trembled slightly, his mind filled with images of his parents and master dying tragically because of his driving.

His master, in particular, felt extremely sad when he thought about how his living master had died just because he hadn't installed a few screws properly.

Tears started falling onto the table, and the steamed bun in my left hand no longer tasted good.

In this world, only his master has been good to him, and he can't just let his master die like this.

Han Jingfan took out a yellow handkerchief from her pocket and wiped away Agui's tears: "Remember next time, never miss a single screw, because you are a repairman, and you also have a responsibility to ensure the safety of others."

Ah Gui nodded vigorously, finally understanding where he had gone wrong.

In fact, Han Jingfan did not intentionally scare Agui. If the repair shop caused injury or death to a customer due to a repair accident, Yu Dawei might have to spend the rest of his life in prison.

For her husband's sake, she was determined to explain this principle clearly and thoroughly to A-Gui today!
We must never allow the other party to have even the slightest bit of wishful thinking about getting the car repaired; we must deeply instill the sense of responsibility in their minds.

Outside, Yu Dawei and two others were still assembling a road roller.

Engine, transmission, and main pump – these are the parts we'll be repairing and installing today.

Fortunately, everything had already been disassembled and reassembled, so only the installation remained, which would take a little longer.

But it would be good enough if they could get all three of them settled in an afternoon.

In the middle of the night, A-Gui ran from the house to them and knelt down before Yu Dawei.

Startled, Yu Dawei quickly helped Agui up, not understanding what was going on.

Then Han Jingfan, who followed in, began to plead for Xiao Agui. Only then did Yu Dawei understand. In the end, he couldn't go against his wife's wishes and let Xiao Agui continue to participate in the car repair.

In the afternoon, seeing that she had nothing else to do, Han Jingfan took the bus to the village and went home. Before leaving, Yu Dawei secretly thanked his wife behind the backs of the others. He was grateful to her, otherwise he might have had to spend a lot of time and effort to educate Agui that night.

For the next three days, Yu Dawei and Lao Ji continued to repair the road roller. When they were lifting the engine and gearbox, an accident occurred. The engine lifting ring was not properly placed and slipped. Fortunately, Yu Dawei was careful and tied two extra steel cables when binding it. Otherwise, the repaired engine would have been ruined.

After installing the major components, the next step is to connect them.

The new water tank was installed, along with two water pumps, water filters, and other components. These are all for the road roller's drainage system. After the drainage system was set up, the center articulation frame was connected, and the cab seat was replaced with a new one.

Regarding the electrical system in the cab, Yu Dawei mainly addressed the issue of some screens not lighting up. After disassembling the control panel, he found a dense network of wires inside. At this point, he had to patiently use a multimeter to search for any aging or broken wires.

These older electrical systems are relatively easy to locate; a single electricity meter is usually sufficient. However, as technology advances and all electrical systems become computer-controlled, repairs will become much more difficult.

Yu Dawei also studied for several years, reading books and searching for information, before he was able to use a computer to look up circuit problems.

Fortunately, this old device was fine. Most of the wires were old and short-circuited. After replacing them, the entire screen lights up, and all the indicator lights could be clearly seen flashing.

With the electrical system repairs completed, the final step was to install the front and rear steel wheels.

Yu Dawei still needed to find a crane to lift the main body of the road roller, then push the front and rear steel wheels to the appropriate positions, and finally slowly lower it before connecting it.

It took Yu Dawei and his team most of the day to figure out how to connect the two steel wheels. The main problem was the strong wind in winter, and the plastic shed made it difficult to control. In the end, Yu Dawei made a tough decision and simply removed the plastic shed to install it in the open air.

Although the process was a bit slow, at least the installation was completed.

Subsequently, Yu Dawei started the road roller to conduct an ignition test.

Turning the key switch, the engine roared twice, and the road roller caught fire.

Since Yu Da was the only one in the entire factory who knew how to operate a road roller, he had to do it himself. The engine oil and antifreeze had been added before starting the machine, and the diesel fuel was also filled up. Now it was time to conduct a working test.

Yu Dawei first let the vehicle idle, then got out to check for any oil leaks in various parts of the road roller, so that he could tighten them in time if any were found.

Knowing that it would take some time for Boss Yu to test the road roller, Lao Ji and Fu Zi went to repair the customers' cars in the yard, leaving Boss Yu and Xiao A Gui to handle things here.

After observing for more than ten minutes, Yu Dawei felt relieved when he felt there were no leaking pipes or connections. Before getting into the car, he repeatedly told A Gui not to go near the leaky pipes and to guard the entrance.

He then opened the car door, got back in, and began to accelerate the engine to pump air into the road roller.

Because the power system of a road roller requires pressure to operate, the air pressure needs to be replenished in advance. If the air pressure is insufficient, the operating standards cannot be met.

The air pump was newly replaced, and at this point, Yu Dawei wanted to check if the air pump was working properly.

After adding fuel, there was no muffled sound of increased air pressure, so Yu Dawei continued to accelerate, eventually flooring the accelerator.

Then depress the clutch, depress the brake, shift into first gear, and test it out.

"The air pump I just bought isn't working?" Yu Dawei frowned, deciding to put the air pump aside for now and see how the vibration effect was.

After all, the majority of the 60,000 yuan spent is on all the parts of the vibration system. It would be a real pain to spend so much money only to have problems.

Turn on the vibration switch and start with a low vibration, or a small vibration. After Yu Dawei pressed the handle switch, the front steel wheel began to make a "whooshing" sound.

Drive forward, adjust the seat, then shift back one gear and drive backward. Finally, do the double steel wheel misalignment and adjustment that a novice usually wouldn't understand. Yu Dawei felt that the overall vibration system was fine. He adjusted it to high vibration and repeated it, and the condition was still good.

During this time, Yu Dawei tried the water spraying system of the road roller again, turned on the water spraying switch on the electrical control panel, continued to move back and forth, and then observed the ground compaction and water spraying. Everything was fine and there were no problems.

Yu Dawei stopped the car and let it idle for a while before getting out to observe again.

Currently, the only problem with the entire Bomag road roller is the air pump, so Yu Dawei ultimately decided to disassemble it and take another look.

After turning off the road roller, the air pump was disassembled and found to be fine.

"Old Ji, come here for a second!" Yu Dawei was a little confused. He had entrusted the installation of the air pump to Old Ji. As the saying goes, the one who tied the knot must untie it, so he was going to ask Old Ji how he installed it.

"What's wrong, boss?" Old Ji was wearing a dog-skin hat, and his stubble was covered in frost. Repairing cars in Northeast China in winter is indeed a difficult task.

"Didn't you notice any problems when you installed this air pump?" Yu Dawei pointed to the black air pump placed on the cardboard box on the ground.

"No, I've put in all the rubber rings that should be in place, and all the hoses that need replacing are the latest ones." Old Ji squatted down and glanced at the air pump. There was indeed no problem. He stood up and looked at the hoses connected to the air pump again. They were all installed normally.

"That means the air pump is fine." Yu Dawei frowned even more. If there's no problem with that part, then it can only be the air tank and the exhaust valve.

"Old Ji, did you change the exhaust valve?" Yu Dawei turned his head to check if the exhaust valve had been replaced with a new one.

"It's been changed," Old Ji replied earnestly.

"What about the gas storage tank?" Yu Dawei asked again.

"Um, I don't quite remember that." Old Ji thought for a moment, his memory of changing the gas tank was rather vague.

"Go ahead and get busy, I'll take another look." Yu Dawei rolled his eyes at Lao Ji. This guy must have forgotten to change the gas tank, and only remembered after being reminded by Yu Dawei.

"Hehe, okay, boss." Old Ji chuckled awkwardly and scurried away.

A boss who doesn't fuss over trivial matters is truly a good boss. He doesn't like his boss bothering him every day with various issues. Even if it might be the boss's fault, they are all adults and naturally have some dignity.

Yu Dawei located the gas tank on the lower side, but it was obscured by a plastic pipe, making it difficult to see.

He took off his gloves, touched the cold, black gas canister with his hand, then withdrew his hand, looked down at his fingers, which were covered in dust.
