Many of our compatriots dream of such a vehicle as an ATV. This hybrid of a tractor and a motorcycle combines their best qualities. It is used for driving over rough terrain, trips to nature or picnics, fishing, etc. The all-terrain vehicle is also actively used when performing various household tasks. An ATV is a fairly expensive vehicle, so many people decide to assemble it themselves. To do this, you will need to prepare the appropriate equipment and components. One of the popular options is to assemble an ATV from Oka with your own hands.
Many of our compatriots have an old but working car gathering dust in their garage. Oka is ideal for assembling an ATV. To do this, you will have to spend a certain amount of time and purchase the necessary parts. You will also need a welding machine and grinder, a set of keys, screwdrivers, and other hand tools. This is an exciting process during which the master will acquire new skills. If desired, a specialist will be able to assemble a homemade ATV from Oka with all-wheel drive.
At the initial stage, a drawing of the future vehicle is developed. You can use a ready-made scheme, but it is much more effective to create your own. When developing drawings for an ATV from Oka, you need to take into account that most of the parts can be removed from the old car.
Advantages of an ATV from Oka
An all-terrain vehicle assembled from Oka parts has many advantages over factory-produced models. One of the positive qualities is the efficiency of such an ATV. Since most of the parts will be taken from the donor vehicle, no significant financial investment will be required. If you have to buy additional parts, you only need a very small amount of them.
The weight of the ATV will be relatively light when compared with factory-produced all-terrain vehicle models, but the power will be significantly higher. The Oka has a two-cylinder liquid-cooled engine. For a car this may not be such a high figure, but for an ATV it is more than enough.
In this case, you can make your own 4x4 ATV with an Oka engine. The all-wheel drive all-terrain vehicle will be functional as well as versatile. It will be able to overcome significant obstacles on the road, cultivate gardens and vegetable gardens, and transport significant loads.

Frame assembly
To make an ATV from Oka, you must first make a base. You should work in a heated room with good ventilation or outdoors under a canopy. At the first stage, you need to assemble a frame, which is created by welding from the following parts:
- The lower and upper spars are made of two pipes with a round cross-section. The metal thickness should be 3 mm, and the cross-section diameter should be 25 mm.
- Auxiliary spars, which are used for struts.
- The spars are bent, which form the upper and lower planes.
- Clamps for shock absorbers and levers.
To install various components on the frame, you need to purchase the appropriate number of metal brackets and other small parts.
Assembly Features
The main advantage of an Oka ATV is its power. A two-cylinder liquid-cooled engine may be too small for an Oka as a car, but for an ATV it is enough.
First you need to prepare the frame for the ATV. It is usually welded. In order to do this you will need:
- Upper and lower spars (they are usually made of two round pipes with a diameter of 25 millimeters and a thickness of 3.2);
- Auxiliary spars (for example, for struts);
- Bent side members for the upper and lower planes.
- Mounts for levers and shock absorbers.
And a number of small parts for installing various components. But at this stage, the search for an answer to the question of how to make an ATV from oka is just beginning. The next thing to take care of is the transmission. It will be quite unique, since despite the fact that an all-wheel drive engine is used, there is no gearbox in this case.
Finalization of the design
After assembling the frame, you should take care of the transmission, which will be unique in this system. Despite the fact that the engine is all-wheel drive, there is no gearbox in the system. In this case, the engine is installed lengthwise, which allows you to change gears and synchronize the transmission with the output shafts. If in the Oka the right and left wheels worked together, then in the ATV it is necessary to create a different type of drive. Two front and two rear wheels will work synchronously. Such modification is necessary in order to provide the all-terrain vehicle with the appropriate performance characteristics for driving on hard off-road conditions.
The technician needs to move the units on the frame to the left, since the horizontal unit of the transmission shafts will decrease. Otherwise, the system will not function correctly. The Oka gearbox needs appropriate modifications. A gear pair is removed from it, instead of which a chain drive will be installed. This will balance the speed and also increase torque at the same time.
The gear shift needs to be lengthened and the gear shift lever installed on the left. There are 4 gears in this design: two in front and two in rear. As the system operates, the speed position of the lever will change.
It is recommended to remove the gearboxes that are installed between the wheels. This is a characteristic feature of cars produced by VAZ. The axles are removed, like the stocking, and shafts designed for front-wheel drive vehicles are installed instead.
Rebuilding the transmission is the most difficult part of assembling an ATV system from an old vehicle.
Completing the build
The corresponding attachments, controls, and gas tank are installed on the frame. All elements are firmly fixed to the frame. The battery needs to be changed, buy the appropriate battery that is suitable for the ATV. Traveling in nature far from home is very important, since without high-quality power to the electrical system, the vehicle will not be able to move.
When all the components and mechanisms are installed, you need to trim the body with metal or plastic parts. The first option is preferable. They will be able to protect all components from damage, since the body of the ATV is often subject to impacts. The surface of the body is primed and painted. You can decorate it with stickers of standard or original designs. If necessary, you can print any image.
At the last stage, headlights, rear-view mirrors, trunk and other additional structural components are installed. After completion of the work, the functionality of the system is checked and modifications are made if necessary.
A homemade ATV is assembled not only from the Oka: read how you make your own ATV from the Ural, Ant, Dnepr, from a walk-behind tractor and a scooter.
Work process
The first step is to make the drawings of the ATV yourself. Put as much effort into sketching as possible. They will be needed to determine the required spare parts and calculate costs.
After creating the drawing, start purchasing components. Usually their main composition includes:
- frame - the main structure on which the entire unit will be supported;
- pipes of various lengths and diameters to ensure the operation of the system;
- rolled metal for installing shields, protection, etc.;
- shock absorbers;
- engine and its components.
The easiest way to make an ATV is with special equipment. If this is not available, the best option would be to contact specialists with ready-made drawings. They will not only do a high-quality job, but will also be able to correct inconsistencies in parts and mechanisms.
The frame should be made individually, according to the dimensions of the intended device. However, if you wish, you can also take a simple frame from a Russian-made motorcycle or car. The easiest way is to make an ATV from Oka with your own hands. Since the Oka has a small wheelbase , this makes it easier to adjust the dimensions.
Suspension and shock absorbers from cars and bikes are also perfect for future crafts. Considering that ATVs are designed to travel over difficult terrain, shock absorbers from a Minsk or Dnepr moped will be an excellent option.
Brakes are a very important part of the design. You shouldn't skimp on them. Create an ATV with your own hands, 4x4 drive, preferably with a brake system from a VAZ. Their strength is designed for cars, so a lightweight four-wheel bike will respond well to such a system.
The handlebar can be taken from any motorcycle. It is advisable that weights be installed on it to reduce vibration from engine operation and movement on rocky terrain. This will reduce pressure and hand fatigue when traveling.
Depending on which operating method you choose, you need to select wheels with wear calculations. For traveling on ordinary roads, simple wheels from Oka are suitable. However, if you want to achieve good off-road performance, it is worth investing in specialized wheels and tires from manufacturers.
And the most important thing is the engine. The best option for the role of a motor would be engines from IZH Jupiter or Planet motorcycles. A new motor will do just fine. Their simple design will help you easily replace worn out and broken parts. At the same time, do not forget about cooling. It is necessary to choose the ideal option for different climatic conditions. Active cooling is perfect, which, unfortunately, has not been used on motorcycles.
A homemade ATV from Oka, the drawings of which, depending on operating conditions, must contain additional equipment, can be equipped with fog lights, a tool box (very useful in case of breakdown) or a winch.
