Shortening the rear axle and axle shaft.
Evgeny (Soroush) The bridge was shortened on both sides by the same length or the right side was longer, tell us if it’s not a secret and by how much on each side, thanks in advance!
Quad bike (Fouad) So I shortened the axle shaft. The right side grew 20 cm, and the left 10 cm, as a result, the base decreased by 30 cm. In pictures 1 and 2, the final stage of work. In 3, the green sketch shows how the turner made it - a hole was drilled in the left side of the axle shaft and a hole was machined in the right side for a finger - the dimensions were adjusted to fit the pressing. In Figure 4 in red, the grooves for welding the parts were welded in three stages and only with a semi-automatic machine. Alignment was mandatory.
Andrey (Rosia) This is how the stocking turned out, also shortened. I cut it, cut off the size and then realized that I had screwed up, I had to cut it behind the seam a little closer to the edge of the stocking, since after the seam there is an internal guide. But it’s true that I cooked it and will keep it that way, but I had to work hard setting it up, otherwise everything is fine. The gearbox is already upside down. I didn’t overcook the back cover - I heated it up, tapped it, installed the gearbox and the buzzing sound. The plug doesn’t interfere either.
Yury (Houshmand) Please tell me what is the best rear axle to use.
Vladimir (Dieter) Yuri, from a Ford Scorpio, or a Toyota Kaldina, and make an independent suspension on A-shaped arms
Yury (Houshmand) Vladimir, thank you
Serega (Cadmos) Vladimir, Why, when installing a bridge, is it turned upside down with the drain plug?
Vladimir (Dieter) Seryoga, this is necessary so that you have 2 gearboxes spinning in the same direction at the same gear ratios
Vladimir (Dieter) Seryoga, if of course you are making a 4x4 quad
Serega (Cadmos) Vladimir, thanks for your help

Homemade rotary rake for tractor
A mini-tractor is understood as a multifunctional universal machine that can perform a fairly large number of tasks on small plots of land such as cultivating an agricultural plot, sowing, harvesting and some utility work. Among the work performed can be noted: arable work on light soils, cultivation with harrowing, inter-row cultivation of crops, spreading fertilizer on the site, haymaking and grass cutting, clearing the territory of snow, debris, rubble, using a mini tractor as a bulldozer when filling holes and leveling surfaces .
Another task of a mini tractor is to transport various loads. When installing additional equipment (modules) on the tractor, it can solve a number of other tasks: woodworking, drilling, hole digging, etc.
The layout of the mini tractor is almost the same as that of its larger brother, but the main difference is the internal combustion engine of lower power. Typically, mini tractors use internal combustion engines with a capacity of 8 to 50 hp. With. However, a mini tractor with a VAZ engine (from a car, for example, VAZ-2106) will be more powerful, although it is made in small dimensions. According to the classification of the state traffic inspectorate, tractors that have an engine power of more than 50 hp. pp., are subject to registration.
The minitractor itself will not perform the above tasks; for this it is necessary to install additional devices and units: mowers, plows, graders, etc. Some people also make them themselves, but there are also industrial samples of such units.
If you have an engine and a frame with a chassis from a car, you can make a mini tractor with your own hands quickly and cheaply. However, if you don’t have an old car, then it makes sense to purchase an industrial mini-tractor; their cost is low, about 2-5 thousand dollars. An old car will cost almost the same.
However, if you decide to convert an old car into a tractor, you should use the tips given below.
When browsing automotive communities, you need to be prepared for anything: both a wild “collective farm” and quite successful home-made vehicles. And if the first is a relative concept and hardly deserves attention, then the second should not be ignored. To get acquainted with one of these “homemade products” we went to Polotsk.
The owner and designer of the unusual tractor, Stanislav Iosifovich, is happy about our visit, but is noticeably modest. The “PR” of his creation is handled by his daughter, without whose support the tractor might not have been known outside the small town. “It seems that MTZ has a worthy competitor” - these are the thoughts that appear when you first get acquainted with a tractor, which is usually assembled in a garage filled to the brim with various spare parts.
“I took up this because I had nothing better to do; I’ve been retired for seven years now. I’ve been collecting for two years, and it will probably take the same amount of time to complete the work. Everything is still “raw” here.
— First I welded the frame. I used a “ten” channel, frames from old beds and discarded heated towel rails. I work as a plumber myself - this is enough goodness. People throw away, but I collect. I started work at random, there were no drawings, no plans - everything was in my head. I tried to make it level and symmetrical - that’s all.
“Then I installed the bridges.” “Niva” served as the “donor”. The struts were found from Opel, the steering wheel and rack were from Honda. The tank became an ordinary 20 liter canister - there is no other way here. The Zhiguli's consumption is about 10 liters, so there is no need to refuel often. Of course, it was not without money: the wheels alone cost 600 thousand - they were “mounted” on Zhiguli wheels. There are disc brakes at the front and regular brakes at the rear. There's even a handbrake! There were no difficulties at any stage. What's the main thing? Measure and do.
— I want to make the tractor universal. The “shovel” at the front is homemade, called “winter-summer”. The lower metal part is used to level roads. And the top one, with an elastic band, is already for winter, so that snow can be removed without damaging the asphalt underneath.

— There will be a cultivator behind. Over time I will install special peaks. They will rotate and loosen the ground at a depth of 30 centimeters. The structure is driven by chains - nothing complicated. But then I’ll close them so that dirt doesn’t get in. Here is also a tooth attachment: tear off ice, if necessary, or asphalt.
— There are two boxes installed: from Lada and from BMW. The transfer case is from Niva. In total, it turns out to be 60 passes. Why so much? For example, I need the tractor to drive slowly and the cultivator to rotate quickly.
— Development plans will last for another year and a half. The base is already ready, but it needs to be put in order. It is normal to lay the wiring, sew up the fenders and the floor. There is metal, there is welding - you just need to do it. There will be no doors at all. I’ll put up the windshield and pull up the awning so that nothing drips on my head. In addition to the peak for loosening the soil, I will install a mini-excavator in the free space behind. There will be interchangeable buckets: wide, narrow, small... I plan to make the reach three meters - it should be enough for my needs.
“In general, nothing special,” the inventor is modest again. — The first time I went out properly was about six months ago, in the winter, I cleaned the road myself. There were people who wanted to buy, they offered $15,000.
Stanislav Iosifovich just grins at a joke about a profitable business. Even though this is just a hobby, in today’s realities there is no need to think far: the designer does not renounce the possible sale of the tractor if necessary.
We study the “interior”: “Zhiguli” panel, steering wheel from Opel. The outline of the hood with the “light” is recognizable as a BMW - it turned out to be left over from my daughter’s car. The headlight housing is from a tractor, but guess what their “filling” is? That's right, “Zhigulevskaya”! The “dimensions” came from MAZ. All this is not just for beauty, but really works. As the designer noted, someday the tractor will be registered with the traffic police. The controls are also no different from those of a passenger car.
— This is not my first invention. There is also an electric cultivator at the dacha. It is also assembled from spare parts from Zhiguli cars: you press a button and it cultivates the land itself. A depth and direction stabilizer is installed; only if it gets stuck, it needs a push.
According to Stanislav Iosifovich, gasoline in the blood is already a family thing, and the main support comes from his daughter: “I remember, I put her behind the wheel, I said: go. And she cries - it doesn’t work. Then how I got involved! The first Mercedes quickly sold out. And now just have time to pay the fines.”

A rotary rake is a fairly useful tool when harvesting hay and a variety of grasses.
But at the same time, it is worth recognizing that home-made structures of this type have a number of limitations, which may lie in the plumbing skills of the manufacturer and in the available materials. But at the same time, they can also help you save a lot.
In addition, depending on your own needs, you can choose the width of the rake or install limiters to select the size of the windrow.
When making a rotary rake from tools, we will need a welding machine, an angle grinder, an adjustable wrench and a drill with a metal drill.
But it is also worth noting that high-quality welds will also require skills in working with a welding machine. This is explained by the fact that the rotation speed of the rotor is quite high, which, if broken, can damage the tractor or create a dangerous situation for human life.
But we make homemade rotary rakes for the tractor from metal rods 10 mm wide, and from tubes with an outer diameter of 50 mm and an inner diameter of 50 mm. We make the frame from a metal profile.
Next, we need a driveshaft, or rather its hinge part, a set of gears and a chain, which we will talk about a little later.
When strengthening structures of this type, you can use sheet steel with a thickness of 5 mm. But the rotor itself is best made from the rear axle assembly of the car. And having the original driveshaft is even better.
What is the number of rear gear teeth on the VAZ 2106 and VAZ 2107 | Topic author: Vera
Anatoly Which gearbox is better for the classic VAZ 2107 2105 2106 2103 2101
on November 04, 2020.
rear axle gearbox VAZ classic 2101 2107 2106 2105 2104 2103 Currently, JSC AvtoVAZ manufactures for production cars and supplies for retail sale drive axle gearboxes of the following models: VAZ 2101 Raisa, VAZ 2103 Galina, VAZ 2106 Valentina. The gear ratio is the result of dividing the number of wheel teeth by the number of gear teeth. You don't need to count the teeth at all. On the driven gear you can read all the necessary information. For example, the marking “VAZ 2106 1143 4537” should be interpreted as follows: “VAZ 2106” - gearbox model; “1143” - 11 teeth on the gear, 43 teeth on the wheel; “4537” is the number of the main gear set. Therefore, the gear ratio of this gearbox is: 4311=3.9. As you can see, the manufacturer of the gearboxes introduced the name of the car model “VAZ 21**” into their markings. This fact often misleads the consumer. So, for example, owners of VAZ 04, 05 and 07 models, out of ignorance, are looking for a gearbox from a “four”, “five” or “seven”, and owners of VAZ 21063 Ksenia cars “safely” install a “sixth” gearbox with a gear ratio of 3.9. And then they wonder why the car has become “stupid”: the acceleration dynamics have sharply decreased, and despite the fact that a high-speed gearbox is installed, it cannot be accelerated to a speed of more than 120 km/h. Meanwhile, the marking “VAZ 21**” does not mean at all that this particular gearbox is intended for this car, for example: gearbox 2101 is for a VAZ 2101 car, and gearbox 2103 is for a VAZ 2103 car, etc. Overall and mounting dimensions All gearbox models are the same. In other words, all gearboxes of VAZ cars are structurally interchangeable. But it is necessary to take into account a number of significant limitations associated with a specific gearbox and vehicle model. Let's take a closer look at these restrictions.
Some aspects of the rework
When the need for a tractor arises, you can always realize the idea of your own version of this machine from scrap materials. At the same time, the cost of rework will be significantly lower than the cost of the finished product. Thus, a mini tractor from Niva will be the optimal assistant in the garden, since the car has a 4x4 drive formula. However, there are some legal points to keep in mind:
- If an old car is purchased, re-registration should be carried out in accordance with current laws. The same applies when transferring a car under a gift agreement.
- After re-registration, it is necessary to notify traffic police officers about the planned alterations. At the same time, they are required to provide a mechanism for returning license plates from an old vehicle (car).
- Upon completion of the manufacture of the mini tractor, it is necessary to register the new vehicle (tractor) and obtain a license plate. Moreover, if this vehicle will be used only in rural areas, then a simplified procedure for registering this vehicle can be carried out.
However, people do not follow these instructions and actively use their modifications for their intended purpose. To be fair, it should also be noted that law enforcement officers often turn a blind eye to these offenses, since they are insignificant (especially if the tractor does not leave the village territory and does not become involved in a traffic accident).
But in order to avoid and significantly reduce the likelihood of problems with law enforcement officers, it is recommended to undergo the re-registration procedure. If a homemade tractor with a VAZ engine is used only on one plot of land, it is recommended to first write off the car’s engine number and body number - this will simplify the engine identification procedure in the future (if problems arise with traffic police officers).
