Chapter 96 Done
Yu Dawei took the lead in repairing the ignition switch, straightened the wires and fixed them in place, and then started the engine again. The engine seemed to be summoned and started up quickly, much faster than before.
Having identified the problem—that the wiring wasn't properly connected—and resolved the ignition switch issue, Yu Dawei began adjusting the boom and arm.
After repeated adjustments and turning the engine on and off, the pressure was finally sufficient. Yu Dawei could clearly feel that the car had become much more powerful. However, he was a little worried that if the pressure was too high, the entire hydraulic system would be ruined. After all, too much of a good thing can be bad.
So he relaxed a little and felt relieved.
In the following period, Yu Dawei began to try out various movements of the wheel digging, just like teaching a dancer to pose in various difficult positions.
Although there were no instruments or meters to aid him, Yu Dawei's eyes and hands served as his own. After each attempt, he would take a wrench and tighten it in a spot that Duan Dahai and Boss Liang couldn't recall.
Sometimes, they even disassemble a certain part, use a small wrench to open the internal parts, repair and adjust them, and then slowly reassemble them.
Mr. Liang had other things to do, so he didn't stay long. He thought that what Yu Dawei was talking about was just practicing driving, but it turned out that there was a process of disassembly and reassembly. It would probably take two or three days to get it right.
"Brother, I'm leaving now. Call me if you need anything." Boss Liang said goodbye and left the courtyard of the scrap metal recycling station.
"Go ahead and get busy. We'll definitely call you if anything comes up." Yu Dawei squatted on the ground dealing with the dispenser that was pressing down on the cardboard boxes; it had just been removed.
After Boss Liang left, Duan Dahai also started sorting garbage in the yard. There were quite a few people selling scrap today. Everyone in the surrounding area knew that there was a young man in Duan Dahai's neighborhood who could repair cars. He was always tinkering with cars, and they were used to it.
They had already seen the other party repair a large vehicle, and now that a small one had come, it should be an easy and pleasant task for this young man.
However, they underestimated Yu Dawei's abilities this time; the disassembly process alone required no fewer than eight attempts.
As Yu Dawei sat on the tire, exhausted, drinking water, he thought to himself that the guy who assembled this wheeled excavator must be a repair genius.
He uses the best parts for many parts, but still needs constant adjustments. But this guy, using some parts that are about to be scrapped, managed to "bring the car back to life".
"If I have the chance, I must go to Dingcheng and Yushui County to see for myself." Yu Dawei had heard in his previous life that the repairmen in Yushui County were all highly skilled and experienced, each one a master at repairing imported excavators. It was a pity he had never been there.
Nearly one-third of the people in their county are engaged in excavator-related industries, including selling excavator parts, reselling distributors, and repairing scrapped excavators, etc.
Excavators have only been imported from abroad for a few years, yet they have already formed a nearly complete industrial chain.
Yu Dawei put down the water tank and continued with the repairs and adjustments.
Three more days passed in a flash, and it was already early July, marking the halfway point of the year. Today, Yu Dawei's small excavator, like a recovered patient who had taken off his hospital gown, finally began helping Duan Dahai sort through the trash in the yard.
This can be considered a comprehensive test of the small rotary excavator by Yu Dawei.
Although the bucket of the small wheel digger is small, it is much better than two human hands at grabbing scrap materials, and it is also quite fast.
Duan Dahai never expected that having an extra wheeled excavator at the garbage station would improve efficiency so much.
Previously, lifting iron blocks weighing one or two hundred pounds was extremely difficult, and sometimes even heavier ones required calling for another person. Now, a single bucket can easily move the iron block.
At noon, the two ate around a large iron pot. Duan Dahai looked at the small wheeled excavator not far away with great envy: "Dawei, this small wheeled excavator is really useful. The work done this morning is equivalent to what I did in three days."
Yu Dawei chuckled and pointed at the wheeled excavator: "This one won't do. If you really want to get one, you should get a tracked one, because tires are easy to get punctured in our yard, and tracks don't have that risk."
"And the front bucket has also been replaced with an electromagnetic chuck!" Yu Dawei recalled the scene of repairing a Caterpillar excavator for a junkyard owner in his previous life. The owner had modified the front of the boom with a particularly large electromagnetic chuck, which worked very well!
"What? Electromagnetic chucks can be attached to excavators?" Duan Dahai had seen electromagnetic chucks before. They were used in very large scrap metal processing plants, with huge frames on both sides and a huge round chuck hanging in the middle. He was always terrified when he passed by them.
“Why can’t we install them? Excavators will be used for a wide range of purposes in the future. For example, farmers need excavators to dig irrigation ditches and do irrigation. Some people even use excavators as cranes.” Yu Dawei thought for a moment, then pointed to the small mountain of scrap in the distance and said, “Brother, as long as we install electromagnetic chucks on the excavator bucket, we can pick up all those lumps of iron and blocks of iron by ourselves.”
"As for those non-ferrous materials, you can just use a bucket to handle them. That will increase efficiency by a lot. I reckon if you really do that, your yard will turn into a factory."
Yu Dawei kept tempting Brother Duan, trying to immerse him completely in the world of waste recycling.
Actually, the waste recycling industry has a bright future. As long as you are careful, you can definitely make money by being a middleman and earning the difference in price.
Furthermore, Duan Dahai is truly unwavering in his commitment to the path of collecting scrap metal, and the future explosion of the flour mill has nothing to do with him.
However, Yu Dawei didn't dare to interfere too much. Having been reborn, he valued fate more than others. Fate is an elusive and unpredictable thing.
Since God has granted him a second chance at life, he absolutely cannot antagonize God and recklessly court disaster.
Duan Dahai remained silent, occasionally nodding or even looking at Dawei with considerable agreement when he spoke.
Yu Dawei could also see that there was hesitation in his expression, especially when he was pondering, he would glance at the pile of scrap every now and then.
It seems reasonable for someone to say they've had enough of a job after doing it for too long.
The two chatted and ate their meal. After the meal, Yu Dawei continued to help Duan Dahai with his work. As the excavator operated, the various systems became increasingly coordinated.
Some previously clogged areas have become smoother through continuous break-in.
The swinging motion in all directions, the coordination between the boom and forearm, and the flexible tilting of the bucket—all these elements have completely submitted to Dawei's skills and obediently follow his instructions.
It wasn't until after 6 p.m., when the diesel fuel in the rotary excavator was almost used up, that the day's break-in period for the rotary excavator came to an end.
Interestingly, by the end, all the waste in Duan Dahai's yard had been disposed of, and there was no need to do anything more. In the end, Yu Dawei suggested that they help Duan Dahai clean up the yard and scrape off the mess on the ground.
After its final debugging and testing, the wheeled excavator has finally completed its transformation.
The hardships and difficulties during the debugging process, as well as the scrapping of replacement parts, put Yu Dawei under great pressure. However, after the debugging was completed and the wheeled excavator could be used on the ground, Yu Dawei had the illusion of an old father watching his child grow up.
"I'll take you to the project site tomorrow. Don't embarrass me. Make a good impression on your third uncle." Yu Dawei patted the boom of the rotary excavator, then turned and went inside to rest.
He was so tired that he fell asleep almost as soon as he hit the bed.
Since the day the debugging started, he hasn't had a proper night's sleep. He often can't sleep at night and goes out of the room to stare at the rotary excavator, pondering it over and over.
Initially, the power system and the hydraulic system were completely incompatible. The wheels could move, but for some reason, the boom suddenly wouldn't lift.
Can the boom be raised? Yes! Then the vehicle stopped moving.
If Yu Dawei hadn't been so experienced in car repair that he guessed the problem might be with the gear lever, he would have even suspected that the car was malfunctioning. How could two systems be operating on their own? He had never seen anything like it in his past life.
Fortunately, all the imperfections are for the sake of the final perfection.
The next day, Yu Dawei delivered the small excavator to his third uncle's project site in the town. Instead of using a large trailer truck to transport it, he simply lifted the boom and forearm and drove away.
This is also an advantage of wheeled excavators; they do not damage roads and can go wherever they want.
Just don't complain about the slowness.
Upon arriving at the project site, I looked up and saw a bald man directing a group of people to work on the exterior of the building. When I saw Yu Dawei, I immediately stopped him.
"Where are you from? We don't need an excavator right now, and besides, your little thing is way too small." The bald man had an ugly face, an upturned nose, a voracious mouth, and thick lips that looked like they were allergic.
Yu Dawei thought to himself that this guy looked so distinctive that he'd probably be a bachelor for life.
However, he still got out of the car and replied with a smile, "My third uncle sent me."
"Your third uncle?" The bald man looked Yu Dawei up and down carefully, but didn't recognize him. He guessed that Yu Dawei was just a pretentious guy.
Recently, many people in the village have heard that there are construction jobs going to be started here, and various small contractors have come over, mustering their courage to find the person in charge.
They have all sorts of connections: they're friends with the leaders, from the same village, the leaders' godson, and even the leaders are the fathers of their children... Today, another person came looking for their third uncle.
They're all incredibly talented!
The bald man looked at Yu Dawei more and more like the pretentious type, and couldn't help but pat him on the shoulder with a condescending gesture: "Brother, I'm in a good mood today, so I'll drive your beat-up little car and get out of here. You little punks can forget about any of the projects in the project department, understand?"
Yu Dawei looked at the bald man in front of him. He was short and had a strange appearance. How dare he threaten him like this?
