Motoblock is called a universal professional mobile tool intended for agricultural work.
From the motoblock you can do a lot, even a snowmobile, the main cutter. Such a construction will be a useful means of movement not only in winter.
Snowmobile is unusual winter transport. Excellent permeability and maneuverability - its main features. By type, snowmobiles are workers, Sports, Tourist and Mountain.
The process of removing the motoblock in a snowmobile is a complex and not simple process, but real.
There are many ways to redo the motoblock in a snowmobile, while designs can be diverse as simple and complex. It all depends on what purpose a snowmobile is needed.
But how to remake the motoblock in a snowmobile so that the assembly is as reliable as possible? This will be discussed in this article.
Transformation of the motoblock in a snowmobile
Let's start with the question. Why motor-block? Explains everything is very easy. The autumn came and gradually all field work went to no. Motoblock, as a bear sent to winter hibernation. Until spring, it is clearly not needed, but not. In winter, he is also faithfully to serve the owner, facilitating his work. It will help in the delivery of firewood from the forest, water from the river and simply facilitate the movement on snow cover. It will make it quick and comfortable.
Why start? From the engine. As a basic unit, the motor-block of the middle class "Neva" is perfectly suitable for our snowmobile, equipped with rear travelers and manual control. Its engine at a fairly low cost, assembled from high-quality Japanese production details. In addition, equipped with forced air-cooled, which is very useful to the future snowmobile. As a result, we get an aggregate with a capacity of up to 7 hp
To independently create a snowmobile, the pipe bender, a welding machine, an angular grinding machine, a power unit and a number of purchased spare parts, which will be needed during the assembly process.
Motoblock Snowmobile: Assembly
Snowmobile assembly on the base of the motoblock should be made in stages:
- To design a snowmobile, you should carefully approach its sketch and provide for composite parts.
Constructive features of the device will depend on the projected tasks. The mechanism itself will consist of a slave and the leading part. The slave part is shock absorbers, and the steering column. The master includes a frame, drive and engine. To competently pick up the snowmobile details, it is better to make a layout (from cardboard, for example) a snowmobile predicted and better if it is in a kind of genuine.
It is necessary to determine the location and shape of all components of the future unit, the assembly of which is going to do with your own hands.
2. Made Rama . It is necessary to initially perform drawings, where to specify all the dimensions of the frame. For convenience, you can use the sample drawing of the snowmobile presented above. To do this, you can apply pipes, preferably pipe 25x25, since it is more reliable than for example, water supply. Thanks to the pipe bending, we make the right shape of the pipes, securing point welding.
3. Brew the joints of the inseparable seam, to the resulting frame we weld the brackets for fastening the engine, seat and steering column. As seats will be useful, for example, old chairs. It will come in handy steering from a bike.
4. As a power, we use two skis connected by hinges with a steering column. We use bolts as rotary bushings. With constant lubrication, they will serve for a very long time. In addition, due to the position of the nozzles, a snowmobile clearance can be changed. To remove the load from the caterpilts, we set the support ski with tension rollers.
5. Installation of the engine and gearbox perform on the leading part of the mechanism.
6. Determine the course of the future snowmobile. It can be a wheeled and caterpillar. In the first case, due to the small weight of the chassis, maneuverability increases, but permeability decreases, especially on loose snow. Therefore, it is appropriate for a snowmobile wheels to equip chains. In the second case, on the contrary, the caterpillars increase the permeability, but reduce maneuverability.
7. Ensure your winter-shoes aggregate is not so simple. To reduce slip, use chains. Take the chamber of the cargo car, lower the air and put on each wheel 5-6 chains, and then pump again. As a result, get the wheels adapted to winter conditions.
8. Another low-budget version of the snowmobile.
9. As another embodiment of winter wheels, a large diameter tires from cargo transport and tractors can be used, pre-electroll make cutouts, as shown in the photo to increase the clutch with the surface of the road.
10. Make four steel wrap in diameter slightly less than a submitted camera, respectively, all snowmobile wheels. In width, they must be 2-3 times more than the appropriate wheel. Next, from the outdoor side, we weld up 7-8 plates with a thickness of 20 mm for better clutch with a canvas. After that, the cameras are lowering, install hoops and pumped again. It turns out inexpensive, but a fairly acceptable version of the wheel for the snowy road.
11. Snowmobile caterpillars can be made at home with their own hands. A conveyor belt with brucks or pieces of pipes attached on bolt joints is suitable for increasing clutch with expensive.
The frame is made of a square section of 25x25x2, a caterpillar is installed on it, an engine with a gearbox, anterior suspension and platform.
The front axle is fixed, fastened to the frame, the rear moves along the frame and the guide and the caterpillar tension is adjusted.
The caterpillars are made of conveyor belt, a tank of 40 mm with a thickness of 5 mm is used as the tracks, with a thickness of the wall of 5 mm.
In the middle installed a reference skiing, to remove the load from the caterpillars between the axes and tensioning rollers.
The leading shaft consists of a star from the Minsk motorcycle, two stars from the snowmobile "Buran", stretch drums.
Chain transmission, gear ratio 1: 3, chain and sprockets from "Minsk. Engine "Sadko" with a cylinder capacity of 200 m3, 6.5 hp With 1/2 and automatic clutch gear.
In the front suspension, the skiing was applied from a children's snowmobile "Argamak", reinforced with pipe 25x25x2. The hinges are made using the M16 threaded connection. Similarly, steering steering. The steering wheel is used from Minsk.
As a result of such an assembly, it turns out an excellent motorized means of transportation with a number from one to two passengers and a small mass of cargo.
It is worth remembering that careless snowmobile skating can be very dangerous and lead to injury and fatal outcome, so you need to adhere to security rules. It is not recommended on a snowmobile to cross frozen reservoirs.
Snowmobile with motoblock engine: more option
Reliable and fairly powerful snowmobile turn out with the engine from the monoblock. Motoblock "Neva" is perfect for the assembly of the structure with a Japanese engine.
In most cases, motor-blocks consist of 4-stroke single-cylinder gasoline engines with air cooling, but 2-stroke engines are also in demand, since they have a small mass, not a complex design, high maintainability, manual launch, etc.
70 kilometers per hour - such speed can be "squeezed" from a regular motor-block, however, only if it is necessary to approach its assembly.
From the motoblock you can make a snowmobile, like a racing car, overcoming the snowy congestion.
At this unit, you can not only plow the land, but also to go to the woods for firewood, hunting, fishing or just ride with the breeze. For residents of long winter snowmobile will be an indispensable vehicle.
Fuel is not consumed, about 2 liters per hour.
In most cases, snowmobiles are manufactured according to the scheme "2 ski ahead and 1 caterpillar behind."This design is optimally stable.

2. Install the engine on the tracked engine.
3. Freak 2 thrust to the tracked engine, which join the transverse beam with skis and the wheel.
4-5. Between the traction set the front rack and seat.
6. Krepim tracked propeller to the beam with controlled skiing and wheel.
7. We take bolts and pins and assemble all the details of the future aggregate.
8. Snowmobile ready.
The uniqueness of the snowmobile is to drive it in places where ordinary cars are just dreaming to do.

Pick out for you:
The main purpose of the motoblock is the processing of the Earth. But many owners, not satisfied with this, find a lot of ways to increase the functional diversity of their two-wheeled assistants. One of them allows to exploit this mechanism and in winter - turn it into a homemade snowmobile.
What kind of snowmate to choose?
There are two ways to make a snowmobile from a motoblock:
- on a wheelchair;
- on a caterpillar.
To make a completely decent Wheel Snowmobile from the Motoroblock with their own hands, you don't need to redo anything in it, it is enough to attach a small trailer to it and put it in special snowmobile wheels.
Make a snowmobile on a caterpillar movement much more difficult, because you have to collect a frame and chassis anew, i.e. In fact, you will have to make a new snowmobile console to the motoblock, and one engine is actually used from the mechanism itself in this design. But this option has its advantages - the design is much more stable, and its permeability is much higher in comparison with the models on a wheeled.
However, in our winter, the winter now does not differ in a large snow cover thickness, so a simpler version of the snowmobile from a motor-block on a wheeled is economically more suitable.
Construction of a self-made snowmobile from a motor-block
You can make a simple snowmobile from the motoblock with your own hands, even despite the drawings. To the frame of the motoblock you need to attach a small trailer to convert a uniaxial two-wheeled mechanism into a two-axis four-wheel vehicle. The only condition - the trailer must have a tough "dead hitch with a fader of a motoblock.
To do this, at that end breathing from the trailer, which is attached to the motoblock, weld the iron bar 50-60 cm long. It is welded in such a way that when the trailer is clutching, it is parallel to the axis of the moto unit.
On the bar at a distance of 5-6 cm from its edges, 2 holes drill. For additional mounting, two iron clamps with holes at the edges are used. These clamps are thrown on the axis of the Motoblock and fasten it with a bolt with a lock nut with a welded cross, passing the bolt through all three holes - in a clamp and cross.
Such an additional mount does not allow the trailer to shift at an angle relative to the motoblock, and the hitch itself acts as a fixing stopper. Such a mount limits the maneuverability of the device, but at the same time reduces the risk of turning over.
The most difficult thing is to make a snowmobile wheels. It is possible to "shine" the wheels of the self-made snowmobile cameras from trucks, having pulled them down and putting them on each wheel 4-5 chains for a winter ride. When the cameras are coming, the ride chains will turn them into a kind of flowers - circles with a ribbed surface.
There is another low-cost way. You need to prepare two metal hoops, the diameter of which is slightly smaller than the diameter of the pumped wheels of the motor-block, and the two hoops with a diameter of a little less than the diameter of the wheels on the trailer. The width of such hoops should be 2-3 times the width of the corresponding wheels.
On each hoop from the back side, 5-6 iron plates are welded, 20-25 mm thick, the purpose of which is to improve the clutch with the surface. Ultimately, if everything is done correctly, it should be a lightweight similarity of the soils, only much wider and with smaller teeth.
Further everything is simple. Cameras on all wheels of the future snowmate descend, we put on them prepared hoops and pump out again. Under the pressure of the aircraft, the wheels are tightly pressed to hoops, as if imprinted in them.
There are several more ways to transform the motoblock in a snowmobile, but they require much longer time, forces and means. Why bother, if a similar design is needed a maximum of 3 months a year, and even then not every day?
During the cold weather, transport on two wheels becomes irrelevant, and sometimes impossible to drive on the snow-covered expanses even by car. What to do in a situation if there is no money for the purchase of a more adapted to the harsh winter of transport?
In this case, you can make a homemade snowmobile. Winter vehicles most often equipped with a caterpillar drive, the steering skis are installed in the front. The snowmobile has high permeability, light weight (70-80 kg), which allows him to ride both valuable snow and on the rolled snow-covered roads. It is easy to control this vehicle, and the developing speed is small. So ride on a snowmobile in the winter, this is not only convenient, but also safely.
Features of homemade snowmobiles
Sale snowmobiles in the CIS are engaged in a huge number of companies. But the prices of them are high even for families with decent income. If you do not want to overpay the money for advertising and are a hardworking and creative person, then try to make a homemade snowmobile.
The self-propelled self-propelled hand is 7-10 times cheaper than the cheapest models manufactured by the factory.
The success of the personnel production of snowmobile depends on several factors:
- your personal skill;
- your engineering thinking;
- the presence of parts and aggregates from other snowmobiles, motorcycles and other things.
It should be borne in mind that driving on a snowmobile, as well as on any vehicle, is associated with increased danger. Despite the fact that homemade devices are usually not able to develop speed more than 15 km / h, to the quality of parts, to welding, to the fastening of elements bolts should be approached with all seriousness. The issue of operational safety and reliability of the final unit must be the main one for any person who has intent to make a snowmobile with their own hands.
Preparation
Before proceeding with the production of snowmobile, you need to calculate the main parameters of the device. If you are a little constructor engineer, it is appropriate to make the drawing of the unit. In principle, all snowmobiles are arranged equally and simple. Your task is to make a reliable apparatus according to the sample and the likeness of all other versions of this vehicle class.
What will be required for manufacture:
- Pipe for frame, for suspension and other frame elements.
The experimental method found that the optimal diameter of the pipe was 40 mm. If you use a profile, then 25 x 25 mm will be enough. Wall thickness - 2 mm. With smaller parameters, the stability of the apparatus to deformities will be reduced. At large - the machine is lost, which, accordingly, will affect the already not brilliant driving characteristics.
- Wheels with rubber on the axis.
Wheels are suitable from quad bikes (small models with a wheel diameter of 30-40 cm), some carts, etc. A total of 2 axes with 2 wheels each.
- Wedge belts or conveyor belt.
The main element of the "caterpillars". The optimal thickness is 3 mm. This is enough for stability and wear resistance.
- PVC pipes.
Of these, soils are made - the second element of the "caterpillars". The optimal diameter of 40 mm with a wall thickness is 5 mm.
- Motor installation.
As a rule, an engine, a carburetor, fuel tank from a motorcycle is used.
- Transmission mechanism.
As a rule, the stars and a chain from a motorcycle, star from snowmobiles are used. Lead shaft from any unit suitable for dimensions.
- Ski guides.
Optimally to take skis from another snowmobile. Since this element should be the most reliable designed for the load of the aggregate itself, plus a driver and possible passengers.
- Steering wheel.
As a rule, the steering wheel from the motorcycle is used, respectively, with a gas handle and a cable.
- Platform, seat, body.
In principle, you can do without a platform, consolidating the seat (s) and the body (optional) directly on the frame. But sometimes there is an additional platform on the frame, for example, from wooden boards, which provide minor depreciation, allow you to place several seats, and at the same time we melt the design.
- Shock absorbers.
This element makes an additional complexity in the design. Therefore, they often cost without it, especially if it is supposed to ride the snow. Depreciation is installed on the front suspension and driver seat. You can take from the old snowmobile or from a motorcycle.
- Small parts.
In addition to those listed above, other standard parts will be required to make a snowmate: bolts, studs, nuts, hinges.
How to make: instruction
First, the frame is boiled - frame. Obviously, the greater the larger the frame, the harder it will turn out the device and the slower it will move. The optimal length of the frame is 2 m plus / minus.
On the frame consistently recorded:
- presenter shaft with host agent;
- power plant with transmission star and gas tank;
- front wheel axis (motionless mounting to frame with welding or bolts);
- rear wheel axis (attached fixed with the help of a moving guide element);
- front suspension with steering wheel construction and guide skiing (skiing);
- seat (s) and body.
Caterpillars are made from drive wedge belts or conveyor belt. The optimal width of the caterpillars is from 40 to 50 cm. With a smaller width (40), the snowmobile will be more maneuveren and better manage. With a larger (50+), the passability of the device improves.
The function of the soils is performed by the PVC pipes indicated above the diameter in half. They are attached to a rubber basis with the help of bolts and nuts. Insufficient width, wedge belts can be fastened with each other with metal primers.
In order to be able to adjust the tension of the caterpillar cloth, the rear wheel axis is attached using a movable guide element, which allows to fix the position of the axis in a certain position.
Additional comments:
- The center of gravity must have about the construction center. Since the power plant is fastened ahead, the driver's seat should be shifted to the center over the front axle or a bit offset.
- The distance between the driving shaft and the power plant must be minimal to minimize the loss of energy transmitted to the shaft.
- If you install a shock absorber under the seat, the front support of the seat is attached to the profile arc hard, and the seat rests on the shock absorber.
- If you make a snowmobile with a calculation on a large load, then it is advisable to set an additional ski of the base for removing part of the weight from the caterpillars (between two tracks). This ski, a long 50-70 cm, is attached directly to the frame. However, such a design assumes a more accurate preliminary calculation, followed by alignment of the height of the "legs", which complicates the production of a snowmobile.
- In the snowmobile tires, it is advisable to maintain low pressure to avoid the rapid wear of parts and high fuel consumption.
The considered snowmobile option is the easiest of construction. In the presence of tools, the welding machine, it can be assembled in the garage without problems.
Snowmobile is a fairly useful unit that is able to overcome high snow drifts, having on board not only the driver, but also a small luggage. The high cost of some snowmobile models makes them almost inaccessible for the majority of the population. Because of this, many residents of the northern and central regions prefer to make snowmobiles from undergraduates. Very often, the motoblock is used in these purposes - a snowmobile on the basis of this unit is obtained quite powerful and hardy.
How to choose a snowmobile engine?
Before making a snowmobile from the motoblock yourself, you need to select the engine for the unit. The optimal option will be the use of a motor equipped with a traction coupling device and a manual control mechanism. These components have motor-block engines MB-1 and MB-2. They are quite reliable, withstand high loads in severe weather conditions, do not fail at extremely low temperatures.
In addition to engines from Russian motoblocks, you can also use engines of Japanese aggregates. Best of all, if you select a 4-stroke single-cylinder engine equipped with air cooling system. Such an engine also shows excellent performance indicators, practically does not overheat, and its details are not corrosion.
The third option is an application for snowmobile from a 2-stroke engine. It has a simple design and a small mass. Such a motor from the motoblock is very easy to repair, having only wrench and a screwdriver at hand.
Snowmobile preparation
To make a snowmobile from a motoblock with your own hands, you will need to prepare materials and equipment in advance.
To work, you will need:
- Welding machine;
- Pipe bender;
- Bulgarian;
- Drill;
- Wrench and screwdrivers;
- Set of fasteners;
- Pipes, diameter 1 cm;
- Steel sheets, 5 mm thick;
- Clamps;
- Vice;
- Lathe;
- Wheels.
In addition to the preparation of equipment and materials, it is extremely important to carefully examine the drawings. They will suggest how to assemble the snowmobile elements.
Collect a snowmobile on the basis of a motoblock is best in a warm dry place, for example, in the garage. In such conditions, the sealant and paint will dry faster, which you will use to design an aggregate.
How to make a snowmobile from a motoblock - a phased assembly
From compliance with the algorithm for the production of snowmobile from the motoblock depends half the result. Therefore, perform all actions strictly in the indicated order. The homemade snowmobile is manufactured in such a sequence:
- To begin with, weld the frame. To do this, use steel sheets and pipes. With the help of a pipe bender, give the parts the desired shape, pre-heating the metal gas burner. Connect the parts solely by welding. After making the frame, paint it so that the metal is not as long as possible by corrosion;
- After complete drying, the paint needs to close all the existing joints of the inextricable seam, after which it is breeding a durable metal bracket to the carrier part of the frame side, which will hold the snowmobile engine. Alternatively, you can breed a bracket from cast iron, but it is allowed only if your snowmobile has large sizes and weight;
- At the next stage, at the bottom of the snowmobile from the motoblock you need to fight skis. To do this, take the steel stripes, heat them, and start the front parts of the parts at an angle of 45 °. Be sure to temper the metal so that he does not return to its original position;
- Next, install the motor, clutch and ignition system from the motor-block. In the back of the snowmobile, install and secure the fuel and oil tank;
- After that, weld to the design of the seat and handles. To the right handle, move the throttle control switches, the Start button and manual brake levers removed from the motor-block. The vertical axis of the handles is connected with skis so that they rotate when turning the steering mechanism.
A manufactured snowmobile maker from the motor-block is practically no inferior to its market counterparts. She is able to carry an adult passenger and his little will chole in deep snow. In this case, the consumption of fuel homemade snowmobile will be at times less.
Making a caterpillar snowmobile
This method will be suitable if you want to get a more passable unit, which can easily overcome not only snow drifts, but also swampy terrain. It should be borne in mind that the caterpillar unit will be heavier that will adversely affect its speed and maneuverability. In addition, for such a snowmobile from the motoblock, a sufficiently powerful engine will be required, outstanding at least 9-10 liters. from.
Do not forget that, as in the first case, in addition to the engine from the motor-block, the snowmobile will need to be equipped with a ignition system, clutch, throttle position switches, a starting device, manual brake levers, and, if there is an opportunity, headlight lighting. At the same time, there is a risk that wires and hoses when moving a snowmobile can wound on the caterpillars. To avoid this, secure all the hoses and wires to the frame with the help of clamps. It is even better if you equip them with rubber or silicone tubes that will protect the wiring from the influence of moisture.
The order of work on the production of snowmobile from the motor-block will in this case will be almost identical. Special attention should be paid to the manufacture of caterpillars. To do this, it is best to take advantage of the transport tape of sufficient thickness. Before starting the manufacture of caterpillars, be sure to study the scheme in which the place of the installation of the main parts of the mechanism is indicated. 
The procedure for making a tracked mechanism for snowmobile from a motor-block looks as follows:
- At first, take a plastic water pipe, a length of 470 and a diameter of 40 mm, and cut it with pieces - they will serve the workpieces for future primrates;
- Split each of the billets along with a circular pipe;
- Finished primrates must be attached to the transport tape through furniture bolts. At the same time, be sure to observe the same distance between them. Otherwise, when moving the mechanism of the teeth, the lead asterisk will be parted on each other, which will lead to the slipping of the caterpillar and its sliding from the rollers;
- Next, drill in the caterpillars of the bolts for the bolts using for this drill and wood drill with a special sharpening;
- Then make the drive shaft of the caterpillar and the support for bearings using steel parts;
- After that, it will remain to establish a tracked mechanism on the homemade snowmobile.
Snowmobile, equipped with a tracked mechanism, can easily overcome areas with wet sticking snow and swampy roads.
If you do not have a sufficiently powerful motor from the Motoblock, but you wish to get a snowmobile that can move through the swampy terrain, you can equip the unit with combined elements of movement.
For this, the caterpillar mechanism should be installed in the back of the snowmobile, and skiing on the front at the wheel of the aggregate. At the same time, the caterpillar mechanism will act as a slave element.
Instruction
First follow the sketch of the intended design. At the same time, refer to the two components of the device: led and leading. The first must consist of polozov, steering column and. The second part must contain a power plant, frame, drive and driver seat. However, if necessary, you can change the design, more adapting it to the implementation of the alleged tasks.
Determine the parts and aggregates of the snowmobile that you cannot do yourself. Check them and approximate the location of the aggregates on, the size of the structure and its individual parts. Approaching the layout professionally, make the plasp - a snowmock of a natural value of plywood or dense cardboard. Make the layouts of all purchased parts, the layout of the frame and collect from this plas. After determine the size and location of parts that are supposed to be made on your own.
Independent framework of the frame involves the mandatory presence of pipe bending, welding equipment and appropriate skills. If all this is not, order the manufacture of the frame in the nearest workshop on the pre-drawn drawing. Make a frame yourself start from the selection of necessary pipes. Pipes removed from motorcycle frames prefer to plumbing. Special frame tubes are usually more durable.
Bend the pipes on the way it is necessary. Before collect the frame, connecting the details of point welding. Perform a preliminary fit of the frame elements and the snowmobile details attached to it. This will avoid errors in design. Conduct the final welding of a single seam, preferably without breaks and other flaws. We weld the engine mounting brackets, a wheel drive, seats, steering column and other parts.
MAKE MAKE in the form of two wide skis. Wellect the steering column and secure it with the use of scaby connections on it. A more complex option involves the use of shock absorbers in ski suspension. If the design of the snowmobile provides for widespread front ski, then the lever from the "Ural" are more suitable as shock absorbers. Directly on the steering wheel, secure the controls from any motorcycle model.
In the second part of the snowmate, secure the engine and gearbox. They also take from any light motorcycle. As a rear wheel (or wheels), apply low pressure tires for self-making. They can be made of suitable rims and pneumatic chambers of automotive tires. In the inflated state, they will be good low-pressure wheels. For movement on loose snow, snowmates are required, located along all circumference wheels (wheels).
If the snowmobile design assumes the presence of one rear wheel, perform the rear suspension by a motorcycle sample. To do this, in addition to the frame, weld the rear pendulum and attach it to the frame through the hinge. Using motorcycle shock absorbers, make a pendulum suspension. Think over and install the chain drive from the engine to the rear wheel. After fitting the drive, install the rear wheel.
If you wish, install two rear wheels, attach the leading bridge of a shortened type to the back of the frame. For this purpose, find the rear axle from the Anti-Truck Muchotrier or yourself roaming the bridge from the passenger car. When using soft low-pressure wheels, the need for rear suspension partially disappears. The use of motorcycle shock absorbers technically complicates the task. The use of car-type shock absorbers will not make the suspension soft, as they are designed for much greater weight than a snowmobile.
