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

Chapter 51: Disassembly, Locating the Problem, and Requesting Parts
"It seems the engine definitely needs repair." Yu Dawei turned around and shouted to the four men in the second team below, "Bring over all the repair tools; we'll need to disassemble some things in a bit."

Without hesitation, the four men turned and ran to the tool shed.

The tools for excavator repair are generally limited to: heavy-duty wrenches, socket wrenches, torque wrenches, pry bars, adjustable wrenches, etc.

There are some special places where special tools are used, but Yu Dawei doesn't need them yet.

The entire excavator still needs further diagnosis to determine exactly where the problem lies before parts can be requested.

After inspecting the excavator's engine, he turned his attention to the distributor, which was covered in black oil stains. He wiped it clean with a rag and found no obvious problems.

Finally, we arrived at the location of the excavator's large pump. We opened the iron door on the side, and there was some space inside filled with miscellaneous items. The large pump was located above.

The moment Yu Dawei saw the large pump, his eyes narrowed slightly. He already knew why someone had touched this car but hadn't repaired it again, instead going to repair another Ackerman 11.

Old people are cunning, and old horses are slippery; this Master Lü is probably no good either.

The large pump, also known as the excavator pilot pump, is essential for the proper functioning of the entire hydraulic system.

However, the pilot pump of this Ackermann 11 was completely rusted, and every screw joint was rusted shut.

Two of the screws showed obvious signs of disassembly, but due to their age, the screw caps had broken off, leaving the lower parts of the screws completely stuck inside.

It was not only difficult for Yu Dawei to remove this screw, but also quite troublesome.

If he remembers correctly, the Ackermann 11 was Volvo's first hydraulic excavator. Although it far surpassed Hitachi in quality, the possibility of malfunctions not found in the first hydraulic excavator cannot be ruled out.

He also repaired an Ackerman machine back then, which was a model after the Ackerman 11, and the main pump had problems.

Looking at the large pump of this excavator, which has been unused for so long, he could almost be certain that some of the internal parts must have some problems.

"Master Yu, shall we dismantle it now?" The squad leader of the second team came over with three team members, each holding some tools.

"Let's disassemble it. First, disassemble the engine, then the large pump. We can remove some parts of the engine's outer surface this afternoon." Yu Dawei glanced at the sky. "Before dinner, find a crane to lift the engine out first."

Four burly mechanics, plus him, a master craftsman, could easily shave the exterior of an engine in an afternoon.

Yu Dawei had the men clearly instructed. Two men stood on top, disassembling the muffler, exhaust pipe, fan, radiator, and other connections. The other two men disassembled the engine connections below.

Finally, the connection point for the large pump remains.

This is the crux of the problem: the space under the entire vehicle is only so big, and the large pump and engine are connected. It's simply impractical to lift them out together.

Removing the screws inside the large pump is also a technical task, because the pump is now severely aged, and if not handled carefully, it could break like the two screws on the outside. Yu Dawei stood with his hands on his hips, looking at the aging pump in front of him, and some ideas gradually formed in his mind.

“This car is not easy to repair.” Master Lü walked over from behind, holding an old-fashioned plastic thermos cup in his left hand: “Without twenty or thirty years of experience, it would be too difficult to fix this car.”

"Is your car fixed?" Yu Dawei didn't respond, but instead looked at the Ackermann 11 behind him.

"Almost done." Master Lü pointed proudly to his Ackerman truck behind him. "It has its share of problems, the gearbox, the swing motor, the engine, and the track rollers all have issues. But now, I've fixed them all up pretty much."

"Time is really too tight. If it weren't so tight, I could fix this Ackerman in about ten days." Master Lü shook his head helplessly. "Unfortunately, the engine of this car doesn't seem to have a common problem. I heard from people here that it was repaired before, but it broke down again. It's burning oil very badly."

"Good luck, young man." After greeting him, Master Lü turned around and went back to the excavator he was repairing, directing a team of people to work.

Manager Wu arrived shortly afterward. He glanced at Yu Dawei, who was working, and then turned around and called Master Lü away.

As for what was said, nobody knows.

Yu Dawei was trying to remove the connecting bolts between the large pump and the engine, but just as he had expected, they were all rusted shut and difficult to remove.

If someone else were to disassemble all the connections of the engine and apply continuous downward pressure, the disassembly of the large pump would likely be even more difficult.

"We need to get Xiaobai to find a crane." Yu Dawei immediately took off his gloves and turned to go to Bai Zhongsheng's office.

Upon arriving at the office, Yu Dawei discovered that it was actually a combination of two rooms. The outer room contained a sofa, desk, chair, and a square solid wood coffee table, while the inner office was smaller.

As he walked in, he saw a solid wood tea table. Manager Wu was there, sitting opposite Bai Zhongsheng, and the two were drinking tea and chatting.

"Dawei's here! How's the car? Is it easy to fix?" Bai Zhongsheng saw Yu Dawei, reached out and picked up a pair of tongs, took a clean white porcelain teacup from the white porcelain tea mug, and gently placed it on the table. "Come and have some tea."

"Sigh, this vehicle is difficult to handle; there are problems everywhere on it." Yu Dawei glanced at Manager Wu. "I came here to ask you to help me find a crane; I need to use it in a bit."

“Dawei, you’re new here and may not know this yet, but every expense in the company requires an application, and it’s all transparently written down.” Manager Wu put down his teacup, stood up, and walked over to Yu Dawei with a sincere smile: “You’re still young. If there’s anything you can’t handle with car repairs, you can ask Master Lü first.”

“Master Lü is a master craftsman I invited from Qingcheng. He has thirty years of experience repairing imported cars, and he is trustworthy.” After Manager Wu finished speaking, he turned to Bai Zhongsheng and said, “Xiao Bai, Dawei is new here after all, so we should take care of him a little. As for the crane, let’s make an exception for him this time and arrange it for him. I’ll go back and inform Lao Huang.”

"Okay, Manager Wu, I'll go find a crane to come over in a bit." Bai Zhongsheng finished the last sip of tea in his cup, stood up, and smiled at Wu Qi.

"Alright, you guys get back to work. Now that we're all part of a team, let's stick together and grow together." Wu Qi's chubby face was full of smiles before he turned and left the office.
