"The parts are almost there, mainly because some parts need to be processed manually." The bangs are talking about the tracks on the back of the snowmobile, which is not finished right now.

In modern snowmobiles, the tracks are made of composite materials, but now, only rubber wires are used, and rubber skins are used to process them themselves, just like retreading tires in a small workshop in Pakistan.

So the progress has slowed down a lot, and after the samples come out, you can let the tire factory come out with a special track, and now the samples have not been taken out, and the rubber factory cannot make it specifically for you.

Besides, bangs don't want to owe favors, don't talk about the plan, when there is time, you can do it manually in the maintenance department, although the service life may not be ideal, but the sample, can be used on the line.

"Some of the motorcycle tests on the plateau are not very ideal, and in some high-altitude areas, it is said that the gasoline is frozen."

"There's not much of a problem with motivation."

"There are no big problems with the longevity of the machine." Sun Aiguo said another thing.

When Liu Hai heard this, he nodded, this is the benefit of the test, in the future when driving on Big Brother's side, there is antifreeze added to the gasoline, otherwise in the environment of Big Brother, gasoline solidification is nothing to say, and many supermarkets over there sell it.

Liu Hai's heart moved, this project can allow teachers to participate, and the general formula is known by himself, and there are not many equipment used in the experiment.

"I'll ask the teacher about this." Bangs engage in motorcycles for the material supply of the plateau, and many places are not suitable for motorcycles in winter, but there are always a few months that are suitable.

Motorcycles need a small road to do it, cars, trucks need a road investment is too big.

Liu Hai didn't think of a helicopter, the first is that it's too late, the second is that the high-end weapons and equipment are taken out, and the country has no ability to produce it, the third is that it will be stared at by the two major social leaders, and the fourth, that is, to copy the big brother's helicopter, and the plateau is useless.

The plateau can be used as a Black Hawk helicopter, just the big brother's thing, it is really not suitable, now the engine used in the helicopter is a star-shaped piston engine, and the modern one uses a turbine engine, and the turbine engine adapts to high altitude and high temperature environments.

Even if it is made by bangs, it is estimated that he is reluctant to equip it, and how to say it, he doesn't need any helicopters for the third brother, as long as there are more supplies.

"Well, it's best to solve it." Sun Aiguo also mentioned that Sun Aiguo's knowledge of bangs no longer knows how to describe it, look at people's offices, most of them, Russian, English, German, Chinese...... Gee.

"Can you do that 1,000-ton hydraulic press?" Sun Aiguo almost gave himself a mouth, why did he say what he thought.

When Liu Hai heard this, he said: "It's okay, there is no casting press, you need to cooperate with the opposite rolling mill, some parts can be forged first, and the secondary processing in the later stage is troublesome." ”

"What's the trouble with this, no trouble, no trouble." Liu Hai said that Sun Aiguo understands, as for the trouble? How can there be trouble, the rolling mill is now basically supporting us, although not directly, but most of the products produced end up on the motorcycle factory.

Motorcycles need a lot of steel plates, because there is no plastic now, all parts are basically metal, tricycle compartments, cabs, etc., and the four wheels come out after bangs, and steel is still needed.

"I still have to find a way to get a casting press." Bangs spoke.

The technical difficulty of the casting press is not too high, the key to the casting press is to ensure the pressure when casting.

"This doesn't seem to be funny, right?"

"Wait and see, I've got a lot of things on my hands." There is no way to do bangs, the technique has to come step by step.

"Also, you first engage in a single-cylinder diesel engine, which was originally intended to introduce a single-cylinder diesel engine from the small book, but now that you are doing it, there is no hurry for the time being." Sun Aiguo said.

Liu Hai knew that the single-cylinder diesel engine of the walk-behind tractor was introduced from the small book, and it seems that it was this year.

"Uh-huh." Liu Hai knows that the introduction of technology now needs to be exchanged for materials, or money, which are all made by workers and farmers who work hard, and if they come up with some technology by themselves, these people will pay less.

The bangs of the walk-behind tractor can't be made, but when the 25-horsepower diesel engine is made, the drawings will be given, and Li Dali and the three of them will make the single-cylinder diesel engine of the walk-behind tractor, and the technology will be thrown to other factories to make ...... after the technology is formed.

Sun Aiguo walked around, went to ask Li Dali and the three of them, and knew that the snowmobile was fast, so he left satisfied.

Li Dali's three-person snowmobile is almost there, and the bangs are almost the same, in fact, the simple drawings are not complicated, mainly because the bangs are testing new materials in the laboratory.

This time, bangs pretended to fail dozens of times, all of which were recorded, and then succeeded.

Otherwise, the bangs can be taken out in three or five days.

The snowmobiles have sleds in front and tracks in the back, and the engines of the 250 are mainly for carrying people and goods, which is much larger than the modern recreational models.

After all, it is military, and in winter, it is necessary to send some supplies to the outpost, run for contact, patrol, etc., and the load capacity is larger.

Then there is another problem, that is, gasoline antifreeze, the freezing point of gasoline is between -40 and -120 degrees, although -40 degrees does not necessarily solidify, but it will reduce fluidity.

The higher the octane number in gasoline, the lower the freezing point, and the freezing point of octane is -57 degrees.

Gasoline is mainly added alcohols, ethers, or oil-soluble film-forming agents, mainly to prevent gasoline engine vaporizer blockage.

Watching Li Dali and the three of them assemble snowmobiles, Liu Hai felt that there were few people in this maintenance department, but the factory director didn't add people in, and he couldn't help it.

And Liu Hai feels that he is not very suitable to be a manager, and it is more suitable to be a researcher himself.

Bangs move mouth, Li Dali three hands, this snowmobile can pull the plow in the future, so the back is designed with a similar design like a hook, and the overall skeleton is also strengthened.

Li Dali and the three of them are very happy to move their bangs and do it themselves, which proves that the leader values himself.

"Section Chief." After Li Dali's three people finished assembling, they looked at the green snowmobile in front of them and waited for Liu Hai's next instruction.

"Let's go report to the factory manager." Liu Hai asked Li Dali to report.

Now it's the end of July, and there are a lot of places where it snows in the northeast in October, so it's just right to carry out a batch of tests.

"This is a snowmobile?" Sun Aiguo looked at this motorcycle, which was completely different from what he usually saw.

"Uh-huh."

"How do you test this?"

"Let's find a piece of sand, but it's just a little experiment."

"This is okay, let's get a batch of samples first."

"Factory director, isn't this left to someone else?"

"Xiao Liu, this is related to the reputation of our factory, let's get a batch of samples out, the test is no problem, if there is a problem with other factories in the future, it will not matter to us, now take out the technical prototype, when the time comes, some guys will not do well, and say that we have a problem." The factory director patiently explained to Liu Hai the doorway in this, once a problem occurs, some people do not look for their own, but look for someone else's, Sun Aiguo can't afford this responsibility, sorry for the name of the factory.
