The village head of the mountain village of rebirth

"The cylinder liners, pistons, piston rings and nozzles of these tractors are all replaced with new ones. The piston rings have sjz rings, no Liaoyang rings, and the valves should be ground for me. If the crankshaft is severely worn, it can be ground and then leveled with additional bearings."

There is nothing else, the valve ejector rod oil pump equipment is generally not easy to break, and it does not need to be replaced for many years.

As for the tractor's rear axle and gearbox, except for the wear and tear of the gears, they usually don't like to be damaged, so they can only be repaired when they break down.

After the engine thing is arranged, the next step is all the tires.

There is a huge surprise in buying a tractor this time.

Even when these tractors were released for storage, some kind-hearted leader actually asked the team members to pad the trailer and the front of the truck.

When the car was closed, the people in the team used jacks to jack up the trailer and the front of the car, and the trailer axle and the front and rear axles were padded with stones and wood, so that the wheels were suspended in the air.

In this way, it is avoided that the tires will not be used for many years, and they will be flattened by the weight of the car body and the front to form a bond and air-dry.

Jiang Yu saw this situation at that time, but he didn't take a closer look. Now he has time to take a good look at these tires.

After careful observation, Jiang Yu was elated.

Except for the 55 and the five Shanghai 50s he drove back to the machinery factory, there are 11 tractors in the agricultural machinery repair factory, including the four legs of the front, a total of 44 bucket tires, 22 driving wheels and 22 steering Half of the wheels can be used.

Especially for the 22 drive wheels, sixteen of them can be used without hardening, and the herringbone tread is still quite high. I dare not say that there are too many of these drive wheels. It is not a problem to use these drive wheels for an average of one year.

The most valuable thing on a tractor is the drive wheels. In terms of unit price, a pair of drive wheels is more expensive than any other component on a tractor, and even an engine assembly is not much more expensive than a pair of tires.

These drive wheels don't cost a lot of money, so they are definitely a big deal.

Two of the other six driving wheels have bare boards, two of the other three are bulging, and one has a foot-long hole on the side. These six driving wheels must be bought new.

Even if he bought three pairs of new drive wheels, Jiang Yu would save money, and he was ready to replace half of the drive wheels.

Compared with the intact rate of driving wheels reaching 2/3, the intact rate of those steering wheels is a bit horrible.

At the beginning, the team only padded the rear axle of the tractor head, but did not padded the front axle. This caused these steering wheels to fall to the ground. After years of weathering and hardening, they were basically unusable.

Those who can drive to the agricultural machinery repair and repair factory are all dealt with. Fortunately, this thing is worthless.A pair of steering wheels is only 40 yuan.

Of the 44 bucket tires, more than 20 usable tires can be screened out, and those tires that are about to be eliminated by Jiang Yu can also be used as spare tires.

一条900-20的轮胎470元，东方红28拖车用的725-20的轮胎四百元上下。

Jiang Yu also prepared a lot of money for changing tires.

It costs nearly 5000 yuan to replace three pairs of driving wheels, and the budget for 50 pairs of steering wheels is [-] yuan. Although the six Shanghai [-]s have been driven back to Jianshan Commune, the steering wheels also need to be replaced.

Then there are the car tires.

Regardless of whether it is 900 or 725 tires, the average tire costs 450 yuan, and Jiang Yu has to buy at least [-] tires to ensure that these tractors can work.

In this way, it takes more than 2 yuan to change the tire.

This is more than half of Jiang Yu's original budget. At the beginning, he was going to spend [-] yuan to change the tires, but unexpectedly saved [-] yuan. It is strange that he is unhappy.

People are in good spirits on happy occasions, and Jiang Yu looks at the time with a smile on his face.

Hold the grass!It's almost 10 o'clock, not good!Get down to business now.

Jiang Yu briefly explained to Meng Xianggui, gave him a few boxes of Daqingshan cigarettes, and asked him to supervise the repairmen and repair the tractor for him.

Then he drove the tractor and hurried straight to the mining machinery shopping mall.

He came to buy jackhammers today, and he wasted too much time in the agricultural machinery repair factory.

He didn't waste much time in the mining equipment store. He had already taken a good look at the equipment last time he came here, and this time he came to pay and pick up the goods, and it was over, without ink stains at all.

There are two types of complete equipment for the jackhammer that Jiang Yu wants to buy, diesel engine and electric motor.

Electricity in the 80s was quite unstable. If there was a power outage, the power would be cut off. The diesel engine was used as a spare tire.

A complete set of jackhammer equipment includes diesel engine or electric motor, air compressor, gas cylinder and pressure gauge, pipeline and jackhammer.

In order to be able to bring more wind cannons, the gas cylinder and air compressor must be powerful, but the requirements for the diesel engine and electric motor as power are not too high, just enough.

Two sets of jackhammer equipment plus the additional purchase of six jackhammers cost him more than 1 yuan.

The mining equipment store has that kind of small manpower crane, and the people brought by Jiang Yu basically didn't use it much, so they installed two sets of equipment on the truck body.

After paying the bill, Jiang Yu drove the tractor to the first transportation team, and asked the people in the team's communication room to call Han Guoxiang out.

"Brother Han! How are you doing with the things I entrusted to you? Are you taking it seriously?"

Han Guoxiang sent the tractor to Jianshan Machinery Factory that day. Before leaving, Jiang Yu gave him a task, which was to see the second automobile team, the grain convoy, and other tractor teams in Donghe County.

Jiang Yu's offer was very tempting. As long as Han Hanxiang contacted him with a tractor, he would give him one hundred yuan.

He didn't believe that Han Hanxiang had no motivation.

Han Guoxiang patted his chest: "Of course I took it seriously, and there are still achievements."

After speaking, he took out a small book from his pocket.

Okay!I have all the small books in my pocket, and I will look like a cadre after a few more days.

"The second transportation team has eight tractors. Because the second transportation team was established later than the first team, the number of tractors is not much. All the eight tractors are JAC 50."

Jianghuai 50 is a tractor produced in Anhui Province. It was popular all over the country in the 80s and 50s. It also won the National High Quality Product Silver Award, although it was not as good as Shanghai [-] in the later period.

Its quality is also just right.

Jiang Yu was overjoyed: "How much is the other party selling?"

"Three thousand and five people will not sell it!"

"I'll have a look at this, and if it's in good condition, I'll stay."

"There are more than a dozen in the grain convoy, but among them are seven or eight small tractors with 22 horsepower, four Shanghai 50s, and three Dongfanghong 28s. People say that if you want to buy it, pack it up, otherwise you won't sell it."

Jiang Yu was not prepared to have a 22-horsepower tractor, it was too small.

"How much do they want to pack? Go and ask if it's [-] a piece, I'll keep it all. Go to dinner first, and we'll talk about it at the dinner table."

At worst, those 22-horsepower tractors were sold for 2000 yuan, and they would not be compensated.

Jiang Yu found a restaurant nearby, went in and ordered eight dishes, including Han Hanxiang, it happened to be a table for eight people.
