Unfortunately, not every person has the opportunity to purchase an ATV in a store. Everything more or less interesting models now they are quite expensive, and buying a used ATV is always a certain risk. In this regard, many motorists are advised to make a four-wheeled all-terrain vehicle with their own hands, using an engine and spare parts from some old Soviet motorcycle. Earlier, we already told you about how to make an ATV from a Ural motorcycle. In today's article, we will talk about other donors that you can use if you decide to assemble an ATV with your own hands.
Why is it worth assembling an ATV with your own hands?
Putting together a four-wheeled all-terrain vehicle with your own hands definitely helps to solve several problems. The first reason people decide to do homemade quad bike, this is of course a small budget. If we analyze the market prices for ATVs, we can understand that such vehicles can be considered almost a luxury. Prices for the simplest and low-power models start at 150 thousand rubles, for example, the Yamaha Blaster YFS200. In principle, such a single "quadric" is enough, but the power will always be lacking.
But models of ATVs with engines with a volume of 500-800 cm 3 will cost much more, about 500 thousand rubles. You can also consider Chinese models, such as the Russian manufacturer Stels, but they will have to be well monitored. New all-terrain vehicles of this brand will cost approximately 300-400 thousand rubles, but the engines are already much more interesting - 45-70 hp.
Nuances in the operation of a homemade "quadric"
If you definitely decided to make an ATV with your own hands, then you should know about the intricacies of its operation. In principle, if you need an all-terrain vehicle to ride in impassable places where patrol cars have never been, then there is probably nothing to worry about. You will have to face problems if you plan to drive even on small settlements, which are sometimes visited by patrol cars. Catching you without documents for this vehicle, then with a probability of 99% they will take it from you. The whole difficulty lies in registering a home-made ATV, because the traffic police will most likely refuse you. In a good way, you can register a homemade product, but this is extremely difficult to do. Therefore, assembling a homemade ATV makes sense only if you operate it in some wilderness.
Making a choice
So, how to make an ATV with your own hands? When creating a homemade ATV, we need to decide on a donor, that is, a motorcycle that will underlie our project. Old Soviet motorcycles are perfect for a four-wheeled all-terrain vehicle. From them we can borrow an engine with a gearbox, a frame, a steering wheel and, if desired, such details as a tank, a seat and other elements. Since we already had an article about a homemade ATV from a Ural motorcycle, in this review we will talk about how to make an ATV based on an IZH motorcycle.
For our purpose, almost all models of motorcycles from the Izhevsk plant are suitable for us. The only thing that is important to understand is the power of the engine. Still, the end result will be a rather heavy structure, so best solution will use latest models- IZH Jupiter 5 or IZH Planet 5. There is no point in considering more interesting models, like IZH Planet Sport, because it is not easy to find them, and if possible, it is better to restore them, because the motorcycle is quite rare and interesting. We turn to the main thing, how to make an ATV and what is needed for this.
Rear suspension
Once you have decided on a donor, in our case it is IZH Jupiter 5, you need to completely disassemble the motorcycle. After disassembly, we need a frame on which everything was held, including the engine. It is quite logical that in order to increase the reliability of the structure, the frame must be strengthened in several places.
Now it is necessary to weld the rear axle so that instead of a wheel, a block of bearings with a chain drive can stand on the axle. An example, you can see in the photo. As a suspension, you can use ordinary shock absorbers from a motorcycle, and parts from an old Zhiguli car are suitable for the rear axle. You can go a more complicated way and install a monoshock absorber, but then again you will have to look for spare parts from the car, for example, from the same Zhiguli or Oka.
Front suspension
Once the rear suspension is finished and installed, it's time to move on to the front of the bike, which is a bit trickier. In the case where we were dealing with the rear suspension, we had the opportunity to choose how much shock absorber will be installed. When creating the front suspension, we have only one option - to use two shock absorbers.
Oka's car is perfect for the role of a donor for the front of the ATV. From it we need shock absorbers, swivel units and a steering trapezoid. However, be prepared for the fact that the spare parts will still have to be changed - something to be welded, sawed off, filed. Also good and more simple option, there will be a monoblock installation with fixed wheel planes. Then you do not have to look for a steering linkage, couplings, hinges and other spare parts.
A monoblock is a really simple option, because it takes literally an hour to install. The only disadvantage of this design of the front suspension is a heavier mechanism. Turning the steering wheel will be somewhat more difficult than with a suspension with shock absorbers.
Engine
Many wondering how to make an ATV with their own hands, they understand that it is worth starting with the engine. And indeed, main detail in the future ATV is the engine. The end result, and indeed the whole structure, depends on how powerful it will be. Of course, you can leave the engine from the donor motorcycle, but in the end the “quad” will turn out to be not so powerful. If, however, a little more seriously approach the creation of an all-terrain vehicle, then the installation is more powerful engine would be a great solution. We hope that we have answered your question about how to make an ATV yourself.
We present the ATV of our regular author S. Pletnev from the city of Ocher, Perm Territory. Another machine built by him testifies to the increased design level and professional skills of its creator. However, judge for yourself...
A year has passed since the time when, after leaving the garage, I tried my first ATV with rear-wheel drive (). And then the thought came: why not now make an all-wheel drive ATV (from the English. All Terrain Vehicle - all-terrain vehicle; similar machines received such an international designation).
Fortunately, at that time a buyer turned up for a buggy (), and the proceeds went to the implementation of a new project.
Year of work for 3 - 4 hours after work and on weekends - and new car was ready for testing, there were only small (and I would say pleasant) improvements: connecting lighting equipment, installing an ignition switch, rear-view mirrors and other little things.
The power unit for my ATV was the engine from the Oka car - 32-horsepower, two-cylinder, four-stroke, liquid-cooled. And if for a car its power was often not enough, then for an ATV it should have been more than enough.
Machine frame - spatial, welded. Its main elements (two pairs of spars: upper and lower) are made of round pipes of the VGP-25 type (water and gas pipelines with a diameter of 25 mm and a wall thickness of 3.2 mm), auxiliary (struts, cross members, etc.) - from VGT-20. The spars are bent: the lower ones are in the horizontal plane, the upper ones are in the vertical one. He bent pipes on a pipe bender, "to the cold." Eyelets (pairs of ears) for attaching the levers and shock absorbers of the suspension were welded to the frame immediately, and various brackets - as the components and assemblies were mounted (in "place").
1 - front wheel(from the car "Chevrolet-Niva", 2 pcs.);
2 - engine (from the car "Oka");
3 - front wheel drive transmission;
4 - gearbox (from the car "Oka");
5 - rear wheel drive transmission;
7 - rear wheel(from the car "Chevrolet-Niva", 2 pcs.);
8 - fuel tank(20 liter canister);
9 - rear trunk;
10 - silencer;
11 - passenger backrest (headrest from the Oka car);
12 - saddle;
13 - clutch basket (from the Oka car);
14 - gear lock lever;
15 - body kit (fiberglass);
16 - steering wheel (from the Ural motorcycle);
17 - instrument panel (from the car "Oka");
18 - front trunk
The transmission of the all-terrain vehicle is peculiar. Although the car is all-wheel drive, it does not have a transfer case. As you know, in the "Oka" the engine is located across, and on the ATV it is installed along. This made it possible to direct the output shafts from the gearbox (gearbox) not to the right and left wheels (as in a car), but to the front and rear axles. That's just myself power unit, interlocked with the "basket" of the clutch and gearbox, had to be shifted slightly to the left relative to the longitudinal plane of symmetry in order to reduce the horizontal angle of the longitudinal articulated shafts of the transmission. Well, their vertical angles turned out to be insignificant.
The transmission is assembled from units of various domestic cars, mostly "VAZ" models. But ready-made industrial units also had to be finalized. For example, from the gearbox (from Oka), to ensure optimal (reduced) speed and increase torque, he removed the main gear pair and replaced it with a chain drive. The gearshift rod also made another one - elongated, with outlets on both sides of the gearbox. The stem can be fixed in three positions: for engaging 1st and 2nd gears, 3rd and 4th and reverse. The lever for selecting these positions is located with right side, and the gearshift lever is on the left.
Interwheel gearboxes - from the rear axles of the VAZ "classics", only their axle shafts, together with the "stockings", were removed and replaced with shafts with CV joints from front-wheel drive models. CV joints as hinges are also used in the remaining intermediate shafts of the transmission.
1 - motor (from the car "Oka");
2 - clutch (from the car "Oka");
3 - gearbox;
4 - CV joint (from the car VAZ-2108, 12 pcs);
5 - final drive gearbox with differential (from VAZ-2105, 2 pcs.);
6 - shaft (from a VAZ-2108 car, 6 pcs.);
7 - wheel (from the car "Chevrolet-Niva")
low gear and no diff lock.
Steering - motorcycle type (lever and shaft) at the top and automotive type(with steering rods) - below, only simplified, without steering mechanism, with one bipod. The steering wheel was first used from a Minsk motorcycle, with a pipe diameter of 22 mm, but it turned out to be a little thin. Later I found and installed from the Ural motorcycle. The steering shaft is made of a pipe with a diameter of 20 mm and a wall thickness of 2.8 mm. At the lower end it has a stroke limiter. At the bottom, the shaft rests on a thrust bearing, and in the middle part it rotates in a detachable nylon bracket-sleeve.
The bipod is made of steel sheet 8 mm thick in a shape resembling the letter "T". A hole with a diameter of 20 mm is made at the edge of the "rack" - a steering shaft is inserted and welded into it, and in the ears there are conical holes for ball tips of steering rods. These holes are reinforced with suitable welded washers. The lugs of the bipod are slightly bent down so that they are almost parallel to the rods.
Wheels - 15-inch, from the Chevrolet Niva car. Tires with appropriate rim size 205/70 (width/height as a percentage of width) with off-road tread pattern. The running diameter of the wheel is about 660 mm.
1 - lower spar (pipe d25x3.2.2 pcs.);
2 - upper spar (pipe d25x3.2.2 pcs.);
3 - rack (pipe d25x3.2, 2 pcs.);
4 - support of the rear upper suspension arm (pipe d25x3.2.2 pcs.);
5 - rear brace (pipe d20x2.8, 2 pcs.);
6 - support of the front upper suspension arm (pipe d25x3.2, 2 pcs.);
7 - front brace (pipe d20x2.8, 2 pcs.);
8 - top support front shock absorber(corner 35×35);
9 - rack of the upper support of the front shock absorber (sheet s5, 2 pcs.);
10 - front engine mount support post (sheet s3, 2 pcs.);
11 - rear support leg of the engine mount (sheet s3.2 pcs.);
12 - eyelets for fastening levers and shock absorbers of suspensions (sheet s5, 18 pairs);
13 - saddle mounting bracket (sheet s3, 2 pcs.);
14 - upper cross connection (pipe d20x2.8);
15 - lower cross connection (pipe d20x2.8.2 pcs.);
16 - radiator support (pipe d25x3.2 cut in half lengthwise, 2 pcs.);
17 - front console of the steps (pipe d20x2);
18 - rear console of the steps (pipe d20x2);
19 - connection of the front and rear consoles of the steps (pipe d20x2);
20 - footrest cross member (sheet s5, 4 pcs.);
21 - lug for fastening a fiberglass body kit (sheet s5, set)
Wheel suspension - independent, on two triangular transverse levers each (upper and lower) with shock absorbers from the Oka car (front). The levers are welded from round tubes of VGP-20 type. Elastic elements (springs) and shock absorbers - from the car "Oka" (rear). Wheel hubs are welded into the wheel ends of the front levers and steering knuckles- from the car VAZ-2109. Both of them had to be improved. I installed wheel studs from the Niva in the hubs, and home-made swing arms in the front fists.
Silencer - self-made, two-section. To protect against temperature warping, the body kit covered it with a remote cover, and insulated the inlet pipe with asbestos.
ATV body kit - fiberglass. I pasted it for the first time, and therefore first studied the recommendations for the implementation of the relevant work. But as it turned out - this process is painstaking, although the result is worth it.
(a - the upper arm of the front suspension; b - lower arm front suspension; c - lower arm rear suspension; g - the upper arm of the rear suspension; all parts, except for those noted specifically, are made of VGT-20 pipe):
1 - beam (2 pcs.);
2 - cross member;
3 - bushing (pipe d37x32, 2 pcs.);
4 - shock absorber mounting eye (steel, sheet s3);
5 - ball joint (from the steering rod of the Zhiguli car)
First, I made the required body kit contours from a steel square pipe with a section of 10x10x1 mm. Fortunately, this pipe easily bends even with hands over the knee. The contour was welded to the frame with the help of jumpers from the same pipe, in places where later (after gluing the body kit), it would be possible to cut off the “tacks” without difficulty. Then he bent the “wings” from hardboard (fibreboard) and fixed them with self-tapping screws to the contour and jumpers. Where the bend turned out to be steep, he attached separate strips from the same hardboard. The front end was removed with expanded polystyrene purchased at a hardware store. It was possible to use polystyrene foam or the same mounting foam, but polystyrene foam turned out to be a more suitable material - it is well cut with a sharp thin knife. I glued individual elements from it into a common structure on a mounting foam.
1 - steering shaft (pipe d20x2.8);
2 - steering wheel connection plate (steel, sheet s6);
3 - brace of the plate (steel, sheet s6, 2 pcs.);
4 - detachable bracket-sleeve of the steering shaft (kapron, sheet s18);
5 - support washer (steel, sheet s6, 2 pcs.);
6 - bipod (steel, sheet 18);
7 - steering limiter (steel, sheet s6);
8 - bearing housing;
9 - thrust tip (steel, circle 15);
10 - thrust bearing
Falshbak - complex shape. It was not possible to bend it out of the hardboard. Therefore, having wrapped the engine with plastic wrap, I began to fill the place intended for it with layers of mounting foam. After each layer, drying is mandatory, otherwise the thick volume of foam may not dry inside. Filled in until the layers went beyond the contour. Finally, after the foam had completely dried, I began to draw the desired shape with a knife. The edges were smoothed with coarse-grained sandpaper.
Under the dashboard, a part went into action dashboard"Oki". I fixed it on the blank, too, with the help of mounting foam. Since the foam is large-pored, the pores were filled with gypsum and then processed. When the shape of the blank began to correspond to the intended design and its surface became more or less smooth, I covered the blank with PF-115 paint. Since I was not going to make a matrix for gluing the body kit on the block, but immediately glued the body kit on it, followed by finishing the surface to an ideal state, then plastering and painting the block could be neglected.
So, the blockhead is ready and in order to glue a quality product, it took: 10 kg of epoxy resin, 1 kg of plasticizer for it and 1 kg of hardener, 15 linear meters of thin fiberglass, 5 m of glass mat, brushes, gloves. It is highly recommended to wear respiratory protective equipment. And the more expensive they are, the more reliable. But experience, as you know, you can’t buy, so I gained it in the process of work.
I used transparent adhesive tape as a separating layer between the block and the product. Carefully, without gaps, he pasted over the whole blockhead with stripes. It took only 1.5 rolls of wide tape.
I diluted the resin by 200 - 300 grams with a hardener and a plasticizer. I used measuring cups and syringes, which is not very convenient. Before that, I cut strips of fiberglass in such sizes that large canvases lay on even surfaces, and on irregularities, pieces of fabric could repeat them without making wrinkles. By the way, the fiberglass moderately stretches along the diagonal of the weaves, “flowing around” the desired shape.
First, he thickly smeared one section of the blockhead with epoxy resin, put fiberglass on it and impregnated it again with resin on top. I glued the adjacent piece of fabric using the same technology with an overlap of 3 - 5 cm. I had to work quickly - the resin sets quite quickly, and the higher its temperature, the faster. Yes, I also heated the resin a little near a powerful lighting lamp for better fluidity.
After wrapping the blockhead with fiberglass in one layer, I began to glue it with glass mat. I got the glass mat thick enough, and it turned out to be good for them to gain the thickness of the product. But it does not hug bumps, so I used it only on flat (or with a slight deflection) surfaces and without overlap. Impregnation with resin was carried out in the same way as when working with fiberglass. It should only be taken into account that it takes a lot of resin to impregnate the stackomat, so you need to dilute it more. Uneven surfaces after gluing the stackomat were glued in several layers with a cloth. Each subsequent layer was applied after the previous one had set a little so that the resin did not leak. And since the process of gluing the body kit took more than one day, after a day break, it was necessary to “roughen” the surface with coarse sandpaper and degrease it - after all, the resin is completely cured during this time. The final layers on top of the mat were again covered with fiberglass, and not even in one layer.
Trunks:
a - front; b - rear
Since I needed a surface, as they say, the smoother the better, and there was not enough experience, dips and pits still remained - I filled them somewhere with one resin, and where with the imposition of pieces of fiberglass. Resin was a bit lacking. I bought more already in the hardware store, in boxes. I liked working with it more, because it was already packaged, and all that remained was to mix the components. And it dried faster than purchased at the company.
After the glued body kit had completely dried, I made cuts in it, dividing the product into three parts: rear fenders and back, false tank with underseat, front fenders and front. Carefully, slightly prying and pulling with his hands with picking, he separated the product in parts without much effort from the blockhead.
Now, having removed the parts, I began to process them separately, bringing them to the desired result. In general, the usual preparatory and painting work on the "whole" technology: first, rough grinding with the removal of large bulges of resin and fiberglass; then painstaking sealing of recesses with putty with fiberglass; then grinding the outer surface and priming with a plasticizer. In conclusion - painting with "metallic" and varnishing with a plasticizer.
Blockhead also neatly cut off and put in the far corner - just in case. The body kit was attached to specially made and welded "in place" mounts on the frame.
In conclusion, I welded front and rear trunks from thin-walled steel pipes with an outer diameter of 20 mm, and in addition to them, “kenguryatniks” that replace bumpers.

How to make a homemade ATV is a question that is the dream of almost any young designer.
However, this kind of dream is far from being realized for everyone and far from being at the age at which we would like. But sometimes dreamers still embody what they want into reality.
Drafting skills, ability to perform complex technological processes, having funds and time are the main requirements when creating a homemade vehicle.
Today we'll show you how to build a homemade quad bike using oki parts and show you the process with a selection of photos.
You can find out one of the ways and make sure that it is possible to independently create an ATV from car parts in the example below.
Do-it-yourself all-wheel drive ATV based on the OKA car (amateur designer Sergey Pletnev)
To begin with, we present General characteristics project:
- Length - 2300 mm;
- Width - 1250 mm;
- Height - (extreme points of the wheels) - 1250 mm;
- Base - 1430 mm;
- Clearance - 300 mm;
- Engine - inherited from the car "OKA";
- Wheels - disks: "VAZ" 2121 (Niva);
- Tires - CoordiantOffRoadR15;
- Shock absorbers - "OKA";
- Hubs - "VAZ" 2109;
- Interwheel gearboxes - "VAZ" classic
- Maximum speed - 60 km / h
- The gearbox taken from OKI was modified by replacing the standard main gear pair with a chain drive.
This was done to increase speed on a flat road. And it looks like this:
Assembled
Disassembled
Water pipes (VGP 25x3.2) act as load-bearing parts of the frame. Were purchased in the form of two segments of 7900 mm and weighing 38 kg in the amount of 1150 rubles.
For levers and suspensions, water pipes (VGP 20x2.8) were also required - two pieces 6100 mm long, weighing 20 kg cost 650 rubles.
Two used rear axles from the "penny" (VAZ 2101) - in the amount of 3000 rubles.
From the G8 (VAZ 2108), fists were taken complete with disks, calipers and other things + drive shafts - in total, 4,000 rubles were spent for all these used parts.
Metal sheets, nuts, bolts, washers, silent blocks, etc. came in handy - consumable fasteners and materials for such cases should always be enough.
From the above parts, with the help of welding, a pipe bender and locksmith tools, such a design was created.
Most structural parts are fastened by welding. The carburetor was installed.
Carburetor homemade four-wheel drive ATV
Metal bars for suspension, engine and axles are also secured with welded seams
The hubs are connected to the suspension with new bushings, washers and bolts.
After the frame was assembled, miscalculations began of the nuances of the position of the engine, the functionality of the gearbox and its attachment, as well as the front suspension with steering.
As a result, the following moves were applied:
From the rear post, the axle shafts are connected to the hubs. Welded mount for shock absorbers
The gearbox uses an elongated homemade rod
The picture shows how the mount for the box was connected and the position of the stem from the outside
The steering knuckle is taken from the "VAZ" 2109 and the steering arm is made of a metal plate independently
After a short test drive, it was noticed that the stem from the box would need a rocker to shift gears by hand - this is the most convenient option in the case of a modified box.
I must say that it was modified to increase gear ratio from the axle to the wheels, because without this intervention, the speed at maximum speed would not have gained more than 45 km / h.
Further Assembly
Side steps are welded to the frame, a front axle is installed, a cardan from the gearbox is connected to the front axle, front shock absorbers are installed. Front axle shafts connected to hubs and axle
Installed brake system separately for rear wheels
Steering and brake system for front wheels installed
Purchased off-road tires (in this case, the most suitable option)
The stage of creating the ATV matrix has come. Mounting foam, cardboard, resin, fiberglass, fittings and more came in handy.
The technology of using materials to create a matrix is a very complex process that requires deep and detailed study.
Light reinforcement and cardboard set the frame of the wings, as well as the front and rear parts of the cladding. The foam was filled with a margin in places where it was supposed to make convex shapes.
The dried foam was processed with a file, a jackhammer, a knife and other tools.
Was installed oil radiator from the helicopter and the first layer of fiberglass is applied
The front suspension is fully assembled. Native ball "VAZ" 2109 from below. Top steering tip from "UAZ"

ATVs are becoming more and more popular due to their lightness, maneuverability, high cross-country ability and at the same time compactness. Indeed, an ATV is a cross between an all-terrain vehicle and a motorcycle. It also has a high cross-country ability as an all-terrain vehicle, it can be used for trips over rough terrain, off-road, in the mountains or in the forest, but at the same time, unlike a motorcycle, an ATV is more stable.
Homemade all-wheel drive ATVs - our answer to expensive equipment
The ATV is not cheap, and not everyone can afford it. But to design a homemade 4x4 ATV is quite simple, you just need old parts from a car or motorcycle, a little imagination and a great desire. By the way, all-wheel drive ATVs are more popular because of their cross-country ability and cross-country ability.
Where to start to assemble an ATV with your own hands?
There are many forums or conversion sites on the Internet that tell and explain step by step how to build, so finding information on this issue is not so difficult. It is much more difficult to parse blueprints, especially if you do not have the necessary skills. But without drawings homemade all-wheel drive quad bike it is impossible to stand, in principle, like any other technique. So if you have a dream to cut across the terrain on a self-assembled ATV, you will have to deal with the drawings. Well, if you have a technical education and you know exactly how the components of machine units work, you can build your own drawing to make unique equipment.
ATV transmission scheme:
The Oka, ZAZ, Ural or Minsk are often taken as the basis for ATVs, but those spare parts that you have lying around like trash in the garage are also suitable. Some spare parts will still have to be purchased, but it is still much more profitable to build than to buy ready-made. And in the event of a breakdown, find spare parts for your team from VAZ, Ural, etc. ATV will be much easier than expensive imported equipment.
Today we will look at how to assemble real ATV, using car parts from VAZ, Oka and various materials that everyone has in the garage.
This all-terrain vehicle was manufactured for use solely for recreational riding. Based on this, in the process of its creation, the author took into account factory ATVs and his own car. The result was an ATV with a number of distinctive features that improved its cross-country ability and significantly distinguished it in comparison with industrial ATVs.
To create an all-terrain vehicle from the materials were taken:
fragment of a water pipe, diameter 32 mm;
pipe 27 mm;
engine internal combustion from the car Oka 11113;
gearbox of the same machine;
front and rear gearbox from VAZ;
hubs, grenades from VAZ 2109;
fiberglass.
List of used tools:
welding machine;
drill;
Bulgarian;
spanners;
a hammer;
knife;
calipers;
roulette.
Step-by-step description - assembling an ATV with your own hands
First of all, a frame was made - from a water pipe with a diameter of 32 mm. The ATV suspension is made on its own - for this you need to take A-shaped levers made of a pipe with a diameter of 27 mm. The engine and gearbox are installed from the Oka car, the differential is welded.
The gear ratio is 43 to 11 this is about the front and rear gear, they were converted to internal grenades from the VAZ 2109.
Disc brakes with hubs are also from VAZ 2109, and 15 radius wheels are installed through spacers.
Next, the craftsman installed and adjusted the clutches of the ATV-ATV:
At first it was decided to place the clutch on the handlebars - like a motorcycle. But in the end it was placed under the leg on the left side. And although this has become an unusual option, as for ATVs, it is nevertheless convenient for the author. While driving, gear changes are easy and precise. At the same time, the all-terrain vehicle can move from a place from any gear, including with a passenger on board - the engine has sufficient power. Gears don't need to be changed often. If you drive on the road, the third or fourth gear is usually on, on the road - the first or second as lowered.
The author built transfer case own design, which made it possible to disable the front axle. Here we can see a photo showing the entire shutdown mechanism. front axle, the main parts of the design:
ATV rear suspension. We prepare the frame before gluing it with fiberglass, after which we impregnate it with epoxy.
We adjust and grind fiberglass on the body, the next step is painting.
In the ATV, we hid the radiator under the plastic in front of the instrument panel. Although there is a very small hole, it is quite enough to properly cool the ATV. It should be borne in mind that if you ride in heavy mud, the hole may become clogged and cooling will be difficult. But nevertheless, as practice shows, when moving on serious off-road, the fan copes well with such tasks. It turns on only under very serious loads, which happens very rarely.
The fact is that the all-terrain vehicle that we have assembled is quite light in weight, and in this case the engine from Oka copes very well with the tasks of an ATV.
Here is a photo with the location of the radiator:
