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

Chapter 95 Debugging Failure
"You stingy thing! Why don't you put more on our own stuff?" Xiao Fang complained from the side.

"What do you know, kid? Butter isn't like engine oil. If you put too much on, it'll just stick to all sorts of things, like grass leaves, dirt, even your trouser legs, believe it or not?" Yu Dawei dipped his index finger in butter and was about to smear it on the other person's pants. (Author's note: "Dungeon" is a dialect word meaning clods of dirt or small pieces of dirt.)
"Ah!" Seeing Yu Dawei bullying her, Xiao Fang quickly dodged backward, grabbed a screwdriver and struck a swordsman's pose, her chubby little face tense up: "Who dares to be so arrogant!"

Kids really know how to play! Using a screwdriver as a sword.

Yu Dawei's lips curled into a smile. He raised the adjustable wrench in mid-air with his left hand and pointed his right index finger forward into the air: "I had no intention of offending you, but you are so aggressive! I have no choice but to use my family's secret technique, One-Finger Divine Skill! Forgive me!"

As he spoke, Yu Dawei dabbed the butter on his index finger toward Xiao Fang's chubby little face.

"Ah! No! Yu Dawei, you big bad guy! If you bully me again, I'll tell Mom and Dad!" Upon seeing the yellow butter on her face, Yu Fang instantly burst into the air and ran wildly all over the yard.

As the two were playfully fighting, Han Jingfan came out with Xiao Muyu, Er Yan, and two other girls. They couldn't help but chuckle when they saw their older brother teasing his little sister.

Xiaofang has a cheerful and straightforward personality. Even though she is about to take the high school entrance exam, she is still like a child who never grew up.

In Han Jingfan's eyes, Yu Dawei was the same; it was as if a boy who never grew up always lived in his heart.

Amidst the hustle and bustle, the noise and commotion eventually returned to the task of repairing bicycles.

After Yu Dawei finished dealing with the chain and chain guards, the next challenge was the bicycle seat.

He rummaged through drawers and found two new screws, then re-secured the seat height. He also sawed off a portion of the extra tube on the bicycle to ensure his sister wouldn't get poked in the butt by the protruding tube.

This is the best I can do for now. Once my little sister starts high school this summer, she won't need to ride a bicycle anymore, and this old guy can be considered to have retired honorably.

After fixing the bicycle, Yu Dawei then lay down at home.

He no longer acted like before, wandering around to this house and that house bragging whenever he had nothing to do back in the village.

Perhaps because of the physical exertion of constantly repairing cars, his favorite thing to do during his rest time was to sleep, then hold his son, and occasionally tease Er Yan and Xiao Fang.

To be honest, in his past life he never liked interacting with his sisters, feeling they were too young and didn't know how to communicate happily with him. But children have their own kind of happiness, and although there was an age difference, the joy they experienced remained the same.

In the afternoon, Old Man Yu returned carrying several packets of herbs, which he had obtained from Fourth Uncle Yu Huai. Old Man Yu was the kind of person who didn't owe favors and rarely went to Fourth Uncle Yu Huai for herbs, but whenever he did get herbs, he would pay the full price.

So what if we share the same ancestry? Does that mean we can't live without food? We still need to earn money to support our families.

Old Yu disapproved of his fourth brother's dogmatic and rigid adherence to ancestral teachings, but fortunately he had a son who was both ambitious and quick-witted.

When Yu Dawei saw the old man return, he glanced at the herbs in his hand and shook his head helplessly. His back pain must have flared up again.

But the old man wouldn't admit it, insisting that, "I've been feeling weak lately, and my fourth brother told me to take some more tonics."

Everyone wisely refrained from pointing it out.

Yu Dawei spent a day at home, a mundane yet tedious day.

But Yu Dawei felt that this kind of life was much better than the busy but fruitless life he had in his previous life.

The next morning, he drove to town alone, and he didn't dare let his father come along.

After working for a few days, the other person's back pain must have flared up again, but they kept enduring it without saying anything.

The old man is a man who doesn't give up easily. He took his medicine last night and was the first one up this morning. He packed his luggage and prepared to continue going to town with his eldest son.

Yu Dawei also forced the old man to stay at home while he went to town.

However, Yu Dawei appreciated the old man's spirit of insisting on repairing cars despite his illness, and in the morning, he praised the old man to the skies in front of everyone.

The compliments made Yu Lao Nian's chin twitch slightly, and he seemed to lose himself. In the end, after satisfying his vanity, he "reluctantly" did not follow Yu Dawei to the town.

However, before leaving, he didn't forget to tell him that if he was needed, he could be called over at any time.

He also gave his youngest daughter a heads-up, "Don't get too close to that boy in your class."

Sigh, being a father can be incredibly stressful sometimes.

The two men, sitting in the four-wheeled vehicle, readily agreed, as if the old man's words were golden pronouncements. Then they waved goodbye to everyone and left.

On the bus, Xiaofang turned into a relentless吐槽 machine, launching into a tirade about the changes her father had undergone in the past few years.

Yu Dawei took his younger sister to school, and then went to Boss Liang's parts store to inquire about the remaining parts.

The good news is that the remaining parts have also been found and will arrive today.

The bad news is that a few more people, lacking common sense, have been raising prices on the spot.

Yu Dawei refused at the time and directly asked Boss Liang to find domestically made alternative parts. He just didn't believe that if others could assemble this wheeled excavator and start it, why couldn't he?
After I've finished debugging this wheeled excavator, I'll upgrade all its parts and then let it do a good job for me, right?
As a master mechanic with top-notch repair skills, he was confident in himself. While the manufacturing process of domestically produced replacement parts was currently limited, Yu Dawei believed that if properly adjusted, it would be perfectly capable of operating normally for several months.

When winter comes, all the projects will stop, and then I can do a thorough inspection myself.

The biggest difference between the Komatsu PW40 wheeled excavator and its predecessor is that it now has its own PW40 engine.

The original PW40 engine is a four-cylinder with average power, but since it is the original engine, it will definitely perform better after installation. This is why Yu Dawei chooses original parts first and other alternative parts second.

After arriving at the scrap metal recycling station, they continued the work of brushing and installing parts. Boss Liang got the replacement parts quickly this time, and Yu Dawei spent two days installing the boom, forearm, bucket, etc., and prepared to start testing on the third day.

Assembled wheeled excavators are very different from original factory excavators. The most important step is to test each component. Just like toy cars, spinning tops, and yo-yos that little boys play with, after replacing the parts, you still need to test their performance first in order to determine whether they meet your expectations.

That night, Yu Dawei walked around the wheeled excavator several times. At first, his biggest worry was the front and rear axles of the wheeled excavator. He was afraid that the previous owner had used inferior gear oil in the front and rear axles.

During the disassembly process, I deliberately removed the front and rear axles and drained the gear oil to check. It was indeed not a very good oil, but it was acceptable; at least it wouldn't affect the operation of the gears.

This could be considered a bargain for Yu Dawei, but he still can't be sure how things will go.

Because the gears in the front and rear axles were also replaced by other brands by the other party, Yu Dawei did not see any problems, but the machine was completely different when it was running and when it was stationary.

"If you don't put it to the test, you'll never know what you're made of." Yu Dawei reached out and patted the wheeled excavator.

The vehicle was extremely dilapidated and old, a stark contrast to the nearly new cab. This oddly shaped vehicle became his own.

After expressing his feelings, Yu Dawei began to pack up his tools. He threw many tools into a basin of gasoline to wash them, then wiped them clean with a rag and put them back in the toolbox.

As night gradually obscured the bright sky, Yu Dawei used a wrench to adjust all the potential problems with the car before the last ray of sunlight disappeared, and then went back.

The next day, witnessed by Boss Liang and Duan Dahai, Yu Dawei sat in the driver's seat and turned the key on the right side. There were three "click-click-click" sounds, and then nothing happened.

Duan Dahai: "..."

Boss Liang: "..."

Brother Yu asked them to witness a miracle, right? How come it was over in just a couple of "puffs"?

In the driver's cab, Yu Dawei was unusually nervous. He clenched his right hand tightly. If he turned it again, the "putt-putt-putt" sound would start again the next second, this time for a little longer than before, but it stopped working again after a few seconds.

"That shouldn't be the case." Yu Dawei scratched his head. They had only just started the fire and there was already a problem. Did this bastard not want to work?

Yu Dawei jumped out of the car and couldn't help but kick the excavator. Then he turned around to check the battery compartment to see if there was a problem with the battery.

The connection is working perfectly, no problems.

"Dawei, this car..." Duan Dahai was a little worried.

"It's nothing, it's all within my expectations." Yu Dawei opened the car door again, got in, took the key out and put it back in, and said, "Keep it to me!"

"Put-put-put-put-put-put!" The engine sound went from long to short, from slow to rapid, and finally a lot of thick smoke billowed out of the muffler exhaust pipe at the rear of the vehicle.

Yu Dawei glanced at the smoke and found it to be normal black, without any blue smoke. He then listened to the engine and found it to be very good!
Duan Dahai and Boss Liang breathed a sigh of relief. Luckily, there was no problem right after starting up, otherwise it would have been too embarrassing.

Inside the cab, Yu Dawei began maneuvering the wheeled excavator forward and backward. So far, it's going well, with no major problems.

Then, when he raised his upper arm and forearm, he found that his upper arm and forearm were weak and powerless when he raised and lowered them. Yu Dawei frowned slightly.

He made a mental note of it, then drove the excavator back from the other side of the yard and parked it in the original repair spot.

He then turned off the engine and got out of the car.

Boss Liang gave Yu Dawei, who had just emerged from the driver's seat, a thumbs-up: "Great job! Master Yu is awesome!"

Yu Dawei jumped out of the driver's seat, walked to the toolbox and took out two box wrenches and one flat wrench: "This is nothing."

The first problem has now arisen: the ignition switch on this rotary excavator is definitely faulty, but it's a minor issue.

The igniter was hanging outside, so Yu Dawei fixed it back in its original position and then straightened out the wires.

Another major problem is that the replaced hydraulic system is not very good, and the pressure cannot be increased.

He doesn't have a pressure gauge on hand right now, so it's hard to determine the exact pressure. He can only adjust the relief valve little by little.
