Homemade snowmobile from a Stihl chainsaw. Preparing for work

08.04.2019

A snowmobile is a unique vehicle for daily use in winter period. It is used for movement across snowy terrain during scientific expeditions, excursions, hikes, hunting animals, and protecting the territory. Such a product can be purchased at a specialized store or made with your own hands. If ready-made structures have a fairly high price, and not every person is able to afford such a purchase, then homemade ones are more affordable Alternative option, made from scrap materials and equipment.

Equipment for constructing a snowmobile

You can make a homemade snowmobile with your own hands using available equipment. For these purposes, experts recommend using:

chainsaws;
walk-behind tractors;
motorcycles.

Important! To make a portable snowmobile at home, you must have skills in working with plumbing tools.

Drawings, options for finished work

The design of a snowmobile must begin by creating a drawing of the desired product. He will help in the process of making practical and functional equipment that will serve for many years.

Finished work option

If you can use ready-made drawings to create a snowmobile from a walk-behind tractor or a motorcycle, then for a design from a chainsaw they are not provided, since each tool has its own specifications and features.

Chainsaw snowmobile

Advice. The snowmobile can be made as either a tracked vehicle or a ski vehicle.

Before you start making a snowmobile from a chainsaw, you need to choose equipment that will have all the necessary characteristics. The best option for this purpose - the Druzhba, Ural and Shtil chainsaws (the power of these tools is ideal for creating high-speed snowmobiles).

Important! The engine and gearbox are the main parts of the chainsaw that are used during operation.

The snowmobile design consists of four parts:

Caterpillars.
Transmissions.
Engine.

Chainsaw Ural

Assembly homemade snowmobile is made not according to some proposed scheme or standard drawing, but based on the materials and tools that the master has at his disposal.

Instructions for assembling a snowmobile from a chainsaw

Assembling a product is quite an interesting job. It consists of several successive steps that must be performed carefully and responsibly.

The first stage is the assembly of the frame base of the future homemade snowmobile. For work you will need steel corners (size - 50 x 36 cm) or steel sheets (thickness - at least 2 mm). The middle part of the structure is made from the corners, and the front and back are made from sheets.

Advice. To give the necessary rigidity to the structure, the metal is bent at an angle of 90 degrees.

Carefully make two through holes to accommodate the track shaft and track wheel guides (tensioners are installed on both sides of the side members).

Important! Front device specifically designed to tension the second stage idler, it also helps in adjusting the track itself.

Special brackets are carefully welded to the bottom of the side members (they are attached at the same distance from each other), support rollers are installed in their open grooves.
The rollers (in rubber covers) are placed on five axes, each of which is attached to the underside of the open grooves.
Between each of the elements special bushings made of duralumin are installed (they are made from a suitable pipe).

Advice. In order not to waste time making rollers and axles for them, they can be borrowed from old equipment for digging up potatoes.

The bracket axles themselves are secured using nuts and locknuts (they are designed to strengthen the snowmobile frame and hold the side members at a certain distance from each other).
Three metal corners are used to make racks for attaching the prepared chainsaw gearbox, and install the intermediate shaft of the chain drive.
A seat for the user is installed on the prepared frame (for these purposes, use a suitable box or Car seat), it is fixed in the area between the middle and rear parts of the structure.

Chainsaw snowmobile

A hole is made in the front section of the frame to accommodate the steering wheel; it is made from a pipe with welded control handles.
Metal gussets are installed in the places where the snowmobile racks are attached (they strengthen the structure, make it stronger and more reliable).

Important! In order for the future homemade snowmobile to have good maneuverability in snowy terrain, it is equipped with a caterpillar mechanism.

A snowmobile drive shaft is made from a metal pipe, and a special round flange is inserted into it for attaching gears.
To create the steering, equipment from old motorcycles or mopeds with three-lever control is used.

The finished snowmobile is light in weight and can easily be placed in the trunk of a car for transportation over long distances. Its controls are so simple and intuitive that even a child can easily use it.

Snowmobile from a walk-behind tractor

A walk-behind tractor is another option for equipment that is used in the process of making a snowmobile with your own hands. Its design practically does not need to be altered, since it is initially multifunctional.

There are three types of walk-behind snowmobiles:

wheeled;
on tracks;
combined.

Walk-behind tractor

Before you start working with a walk-behind tractor, you need to decide on the type of future design. The complexity of the master’s work, as well as the duration of the entire process, will depend on it.

Construction of a snowmobile from a walk-behind tractor

Important! For creating wheeled snowmobile there is no need to redo the steering system; special attention needs to be paid only to the device frame and skis.

The snowmobile frame is made of metal pipes or angles (it should be rectangular in shape).
A box or chair is attached to the finished base to accommodate the driver.
Skis are made separately from angles and sheet metal and welded to the frame.
Ready design attached to the walk-behind tractor and used for its intended purpose.

Snowmobile from a motorcycle: a guide for masters

Making a snowmobile from a motorcycle is not so easy. If the assembly of previous products did not cause any difficulties, then with this design you will have to suffer. The work will require not only tools, materials and equipment, but also skills in working with a welding machine and other equipment.

Important! Motorcycles "Ural", "Izh" and "Dnepr" are the most suitable models for making a snowmobile with your own hands.

Snowmobile design technology

A suitable frame is made from metal pipes of different diameters and steel corners. Its base is made in the form of a rectangle (its dimensions are 150 x 43.2 cm).
The steering beam is constructed from metal corners (its dimensions are 50 x 50 x 5 mm), its parts are sheathed with dense metal overlays. The finished structure is installed in a horizontal position on a drilling machine.

Motorcycle Izh

The frame and the finished beam are processed at the joints, special grooves are prepared for reliable fixation elements.
The front crossbar of the frame is equipped with a strong corner.
The seat is attached to the frame of the structure.
Make holes in the side members.
A channel is welded between the steering and middle sections.
Select a suitable track sprocket and rubber band for further installation (suitable dimensions - 2200 x 300 mm, thickness - no more than 10 mm).
The caterpillar itself is carefully sheathed with nylon so that the material does not delaminate during use.

Snowmobile from motorcycle

Install the transmission, which consists of a front and rear axle. The front one is the drive one, it consists of a tubular shaft, a track sprocket and rollers (the sprockets themselves are fixed with through bolts). The rear axle structure consists of a track drum and a tubular shaft.
The skis are welded to the structure of the snowmobile (sheets of steel and metal corners are used for their manufacture).

The control system of a homemade snowmobile from a motorcycle is quite complex to design. It consists of:

longitudinal traction;
lateral thrust.

From the information presented we can conclude: a homemade snowmobile from elements of a walk-behind tractor, chainsaw or motorcycle is a reality. Any craftsman can make it. For productive work you will only need certain skills, equipment, tools and materials.

We also make our own snowmobile from an old Friendship 4 chainsaw.

The idea of making a snowmobile

In general, the idea came in the summer to make winter transport for driving, initially I wanted to make a snowmobile with a caterpillar, but I realized that I couldn’t take it out due to money and the right tools in the garage, so it was decided to make a mini snowmobile with rear wheel from a scooter with welded corners, started building on September 27, 2017.

Snowmobile design

Front ski

I found a piece of old plastic pipe and cut it in half, heating it with a torch and straightening it, after which I took 2 corners, welded them together, welded a spout in front and placed it in the middle of the pipe, after which I tightened it with screws.

Transfer to Wheel

I took it from a scooter at 8 and welded the sprockets from the Minsk motorcycle there, the driven one at 41 and the drive at 15,
but after one month of construction they offered to sell me a wheel with sprockets, a chain and a chainsaw, I decided to sell it because the extra money wouldn’t hurt in my workshop. In the end, I found a wheel from a garden cart, I welded corners to it, and then made an intermediate shaft , but it turned out to be a bad idea, since it was not possible to set the chain and the chain simply fell off, in the end I removed the intermediate shaft and installed stars from Izha, Leading-9, Driven-43, the gear ratio turned out to be 4.7, after testing it showed that this gear ratio Enough to pull 3 people.

Frame and attachments

I made the frame from what was in my garage, the remains of profiles, pipes of various diameters, and angles.
On a piece of paper I sketched out drawings of what my mini snowmobile should look like, but without any dimensions, the frame was welded by eye, adjusted in the garage itself, I welded everything myself, the side supports were old children's skis, a friend gave them to me, so I didn't have to I came up with something and made it from ready-made ones, I secured the skis with self-tapping screws, but after the tests the skis tore out and I had to put them on M4 bolts.

The seat was covered with a rag, but then I decided to cover it with leatherette.

The throttle handle was taken from the Izh Planet 3 motorcycle, the tank from the Druzhba 4 chainsaw, but after the first test I decided that I needed to attach a tow bar for riding with friends on the ice, but I realized that it’s not very good to feed friends with snow from behind because on their Sometimes I find myself in the same place, I have attached a small shield.

The project and its future

On given time the project is being finalized and is actively used by me on weekends for good time conduction, this snowmobile travels current along dense snow ice and loose snow.

Snowmobile manufacturing costs

Wheel from a wheelbarrow - 200 rubles.
Stars and chain 400 rub.
Dermantin 200 rub.
Electrodes Arsenal MP3-3mm 150 rub.

Result: 950 rub.

For this price we get a fully working snowmobile that drives, this is the price of one trip to the store, I think it’s not bad.

Video on making a snowmobile

There is also a video on my YouTube channel of how I created it from A to Z.

With the arrival of winter, people begin to forget about their two-wheeled friend, actively searching for new means of transportation. At the same time, you don’t have to spend a lot, since a snowmobile can be an excellent form of transport, you can create it yourself.

From a practical point of view, moving through snowy areas a passenger car not relevant. And sometimes it’s even unrealistic. Whereas, ideally, a snowmobile will help solve the problem without much difficulty.

How to make a homemade snowmobile from a chainsaw?

Before you begin directly assembling the snowmobile mechanism, you need to create drawings and work based on them. Everything so that the unit can work fully, and everything in the car is thought out to the smallest detail. There’s not a lot of space anyway, so each node should have its own place.

Which chainsaw should you choose?

To create a snowmobile you can use various chainsaws. The most suitable options would be the Druzhba, Ural and Shtil models. And which unit to choose - it all depends on your desire.

Friendship

Basic positive side Using the Druzhba chainsaw as the starting material for making a snowmobile with your own hands is considered to be its simplicity of design. Here is an elementary assembly, where each part plays its role. No extras, just the essentials.

Technical certificate:

power – 1 kW;
weight - up to 12 kg;
engine (two-stroke);
tire length – 45 cm;
fuel (gasoline).

Ural

The specialized professional chainsaw "Ural" was created specifically for felling tree trunks. This is a very convenient mechanism during operation, characterized by high power. This unit is an environmentally friendly device that can be used even in harsh winter conditions.

How to catch more fish?

Over 13 years of active fishing, I have found many ways to improve the bite. And here are the most effective:

Bite activator. Attracts fish in cold and warm water with the help of pheromones included in the composition and stimulates its appetite. It's a pity that Rosprirodnadzor wants to ban its sale.
More sensitive gear. Read the appropriate manuals for the specific type of gear on the pages of my website.
Lures based pheromones.

You can get the rest of the secrets of successful fishing for free by reading my other materials on the site.

If you decide to use a Ural chainsaw to create your own snowmobile, this is right choice. Because the technical specifications This machine fully meets the stated requirements.

Technical certificate:

engine (gasoline, two-stroke, single-cylinder);
power – 3.68 kW;
weight – 11.7 kg;
parameters – 46 x 88 x 46 cm.

Calm

The Shtil chainsaw is also suitable as the main mechanism for creating a snowmobile. It is made of environmentally friendly material, harmless to humans, has good power and it works silently. Therefore, your trip will be very comfortable.

DIY chainsaw snowmobile manufacturing diagram (drawings)

Light snowmobile made from a Ural chainsaw: 1 - steering wheel; 2 - fuel tank(from chainsaw "Friendship"); 3-power unit (from the Ural chainsaw); 4-steering ski stand bushing (pipe 030, 2 pcs.); 5-steer ski (2 pcs.); 6-drive caterpillar gear (nylon, sheet s1 5, 2 pcs.); 7-track (from the Buran snowmobile, shortened); 8-frame; 9-support roller (from potato sorting, 18 pcs.); 10-backrest-limiter strut (1/2 pipe); eleven- stretching device caterpillars (2 pcs.); 12 - caterpillar tension gear (nylon, sl5 sheet, 2 pcs.); 13-bearing No. 80204 in the housing (4 pcs.); 14-box-trunk (bottom-plywood s4, sides-board s20);

15-seat (cover-plywood s4, foam rubber, leatherette); 16 - 1st stage of chain transmission; 17 - 2nd stage of chain transmission; 18-backrest-seat limiter (1/2″ pipe) 19-driven sprocket of the 1st chain drive (large speed reducer-intermediate shaft sprocket), z = 38; 20-drive sprocket of the 2nd stage of the chain drive (small speed reducer sprocket), z = 10; 21 - driven sprocket of the 2nd stage of the chain drive (drive sprocket of the caterpillar drive shaft), z = 18; 22-drive sprocket of the 1st stage of the chain drive (gearbox output shaft sprocket), z = 12; 23 - lever steering knuckle; 24-Tie Rod(2 pcs.); 25-steering shaft with bipod; 26-beam front axle(pipe 030); 27- drive shaft caterpillars; 28 - caterpillar tension axis.

First, you need to create diagrams and drawings to create a snowmobile in order to connect the following components:

engine;
transmission;
skis or caterpillar.

Moreover, you don’t have to design the caterpillar yourself; you can take an existing mechanism from an old Buran. And if you need to do children's transport, then the skis will be good.

Racks

Steering ski: 1 - runner (nylon, sheet s20, from a children's snow scooter); 2-spring (normally stretched, from rear shock absorber moped); 3-support spring bearing; 4 - undercut (duralumin corner 20×20); 5 — — spring cover (angle 35×35); 6- fastening the spring to the cover (M8 bolt with washer); 7 - support lever (pipe 30×30); 8 - eye for attaching the fork stand to the ski lever (steel, sheet s2); 9- eye for attaching the support arm to the ski (steel, sheet s2); 10-axis (M8 bolt, 2 pcs.);

11-steering knuckle post (bicycle steering post with crown and part of the fork); 12-steer bipod (steel, sheet s4); 13- fastening of the steering bipod (teak M16); 14 - fastening the spring bearing and the lever eye to the ski (M5 bolt with a countersunk head, 7 pcs.); 15 - lever bushing ( steel pipe diameter 30); 16- plain bearing (nylon bushing, 2 pcs.); 17 - strut bushing (steel pipe with a diameter of 30) In the top view, parts 11, 12, 13 of the steering knuckle are not shown.

Steel corners measuring 3 x 3 cm can be used as stands for making a snowmobile. They are connected by steel crossbars. The result is a not very large portal. To create a platform, it is recommended to connect a sheet of steel 2 mm thick using spot welding to its front part and middle right side vehicle design. This is where the gearbox of our chainsaw and the chain drive shaft will be placed in the future.

It is recommended to mount a small module on a fragment of the arch of the rear portal and the middle of the car, which will become a good support for the seat.

The connection between the front frame and the front axle cross member is ensured using a beam. As a connecting element in in this case a standard water pipe with a radius of at least 1.5 cm protrudes.

At the end of this pipe, the steering ski bushings are welded, and a stand is mounted in the middle of it. The latter will act as an engine subframe.

Please note that at the joints of the racks it is additionally recommended to use steel gussets 2 mm thick. This will make the vehicle reliable and durable even in harsh winters.

Caterpillar

Snowmobile frame with track block: 1 - — rear end spar (steel sheet s2, with flanges, 2 pcs.); 2 - tensioning device (4 pcs.); 3 - rear portal (corner 30×30); 4-middle part of the spar (angle 50×63, 2 pcs.); 5-bracket-fork for installing the axle of the road wheels (steel sheet s2, 10 pcs.); 6 - middle portal (angle 30×30): 7 - platform for mounting the gearbox power unit and intermediate speed reducer shaft (steel sheet s2); 8 - scarves (steel sheet s2.4 pcs.);

19—track drive shaft; 20 - drive sprocket of the drive shaft (driven sprocket of the 2nd stage of the chain drive), z = 18; 21 - steering knuckle bushing (pipe diameter 30, 2 pcs.); 22 - front axle beam (pipe with a diameter of 30); 23 - scarves (4 pcs.); 24 - engine stand (pipe with a diameter of 30); 25 - roller bandage (rubber ring, 18 pcs.)

If you decide to make a mini-version of a snowmobile with your own hands, then you can use tracks from the old Buran as tracks. But this spare part

it is necessary to modify it a little, shortening the workpiece by at least half a meter and connecting it with transport tape. Gears can be made from a sheet of nylon 1.5 cm thick.

Drive shaft Track drive shaft (tension shaft is the same, only position 4 is replaced by position 1):

1-left (along the way) tip (steel, circle 22); 2 - shaft (steel, pipe 028×2); 3 - flange for fastening the gear to the shaft (steel sheet s4, 2 pcs.); 4-right (along the way) shaft tip (steel, circle 29); 5-tooth track drive wheel (2 pcs.); 6-frame spar (2 pcs.); 7 - bearing housing cover (steel, 2 pcs.);

8 - bearing 80204 (2 pcs.); 9- bearing housing (steel, 2 pcs); 10 - drive shaft sprocket; 11 - fastening the sprocket on the shaft (M12 nut with widened and spring washers; 12 - key (steel 20); 13 - seal (felt, 2 pcs.); 14 - fastening the gear to the shaft flange (M8 bolt with widened and spring washer , 8 sets); 15-fastening the bearing housing to the spar (M6 bolt with spring washer, 4 sets) The drive shaft acts as a tubular element with a radius of 1.4 cm.

A flange with special holes for fixing the gears is placed on top of it. At the end of the drive shaft, pin tips are pressed in and welded using the contact welding method. In addition, they must be machined for bearings.

About the engine The most important part of this mechanism is the engine. Other spare parts, for example, a chain and a tire, are not so important in the process of designing the type of transport in question. In this case, the most important thing is to monitor in time motor. If the latter is in good condition, the snowmobile will work for a very long time and without any complaints.

In the event that you want to use a chainsaw imported production, you should not immediately buy a new unit. You can also use the mechanism former use. Another element that should work without questions or complaints is the gearbox.

Asterisks

Please note that in this case the tip on the right is created slightly longer than the one on the left. A keyway is made on the extension to fix the chain drive star. It is this element that is called the track shaft sprocket, which is securely secured with a nut. Although initially it is necessary to create the desired thread on the product.

The star that is on the first stage must have greatest number teeth For example, the Ural chainsaw engine has 38 units.

Steering

You can use the handlebars of a scooter or even a regular bicycle as a steering wheel. Here it is important to subsequently output manual control to the element. It is recommended to make the set so that the central axis instantly adjusts the traction for further control of the skis and comfortable movement.

Brake system

This vehicle does not have a braking system at all, but it can be made if desired. But there is no particular point in this, since the machine does not develop high speeds. Although everything is done solely at your discretion.

It is very important to draw your attention to the fact that a homemade snowmobile does not fall under the category of vehicles under the Law. Therefore, any movement through the snowy expanses in this case is carried out solely at your discretion and risk. There is no provision for motorway traffic.
Do not confuse a snowmobile with a floating all-terrain vehicle. Though appearance They are somewhat similar, but their total weight ratio is different.
Since the power of the chainsaw is small, transportation of heavy loads is not provided. Most often this is a car with one seat.
If you would like to travel to dark time lighting (headlights) can also be provided during the day. This is very convenient and will greatly secure your movement.

Snowmobiles are an alternative means of transporting people and goods over snowy terrain. Domestic market offers wide choose mechanisms necessary for tourist and scientific expeditions, hunting, active rest, sports and travel in winter.

The cost of the units is high. Therefore, many craftsmen make them themselves from any stale equipment: walk-behind tractor, mini tractor, boat.

Chainsaw snowmobiles are the simplest design solutions.

How to make a snowmobile from a chainsaw

The snowmobile is manufactured according to one of 2 schemes:
single-track (2 skis in front, 1 track in back);

two-track (1 ski in front, 2 tracks in back).

Any snowmobile device has the following design:
Engine.
Supply system.
Oil injection system.
Transmission.
Chassis.
Steering.
Frame.

Electrical equipment. Before you begin making a homemade snowmobile from a chainsaw and its further assembly, you need to design drawings of all working units and general view

vehicle. It is better to draw each assembly unit separately and take out the dimensions.

During the development process, the brand of gasoline tool is taken into account.

Models such as Druzhba, Ural and Shtil are well suited. The Druzhba chain saw has a simple design. The disadvantage is low power

motor (1 kW) with a large tool weight (12 kg).

The Ural has a weight of 11.7 kg and an engine power of 3.68 kW.

Advantages of the model:
ability to work at low temperatures;

high environmental friendliness.

Racks

When making a snowmobile from a chainsaw with your own hands, you can choose the Shtil brand. It is characterized by noiselessness during operation, a power of 1.5 kW, and has a nominal weight of only 3.9 kg. The initial stage is making the base frame structure from welded spars. For the middle part, corners 50x63 mm made of hardened steel are used, the front and rear are made of S2 steel with a flange at an angle of 90°. All elements must have holes of the same diameter for mounting with a track wheel and drive shaft

. Brackets for road wheels are welded to the bottom of the frame.

The racks are made from 30x30 mm corners and connected by metal crossbars. The result should be a structure in the form of a small portal. A platform is required for the mounting location of the chain saw gearbox and the chain drive shaft. Sheet steel of the required size is selected, usually 2-3 mm thick, and welded to the center of the right side of the module and the portal. At the back of the portal and at the same time in the middle of the module, a place is formed for the seat, which is subsequently made from boards and fabric or removed ready-made from old technology

The front spar and the drive axle traverse are installed to the beam, which is a standard water pipe with a radius of 0.75 mm. Steering ski bushings are welded at both ends, and a stand for the engine subframe is welded in the center. The mounting points for the supports are reinforced with 2-mm metal gussets for strength and stability of the structure.

Caterpillar

A mechanism from the Buran unit is used as a caterpillar, the belt is shortened by 0.75-1 m. Gears gear transmission planted on transverse shafts, then the canvas is laid. The caterpillar gear is made from a nylon sheet measuring 15 mm.

it is necessary to modify it a little, shortening the workpiece by at least half a meter and connecting it with transport tape. Gears can be made from a sheet of nylon 1.5 cm thick.

To make the drive shaft, a metal pipe with a diameter of 14 mm is taken, and flanges are installed on top to fix the wheel teeth. At the ends of the mechanism, pin tips are pressed in and welded with space provided for bearings.

Engine

The snowmobile engine is the most important component that affects the operation of the entire self-propelled vehicles. Therefore, experts recommend using power plant from a Shtil chainsaw with an engine power of 1.5-3 kW. The motor is mounted on a stable support of the cross beam. The gearbox is rotated 180°, fixed on the platform, and the intermediate shaft of the 2-speed transmission is also mounted. The fuel tank is installed on top.

Asterisks

The drive sprocket with an internal key made of St20 is attached to the shaft with an M12 nut and a spring washer. For precise fixation, a thread is cut on the tip required parameter. It is taken into account that the 1st gear stage corresponds to a large sprocket with a maximum gear ratio(on the Ural engine there are 38 teeth), 2 stages - a small drive sprocket with 10 teeth.

The chains are of a standard type, with a pitch of about 16 mm.

Brake system

If the snowmobile is designed to travel at low speeds up to 30 km/h, then braking system may not be provided. Vehicles are stopped by friction in the chassis and transmission systems.

Steering

Control - steering on support-steering skis. The support arms are rigidly connected to the steering shaft bipod. The steering wheel is two-handed, with a gas handle mounted on the right side.

What other winter equipment can be made from a chainsaw?

A line of riding equipment snowy roads based on a chainsaw can complement the following homemade products:

snowmobile;
snow scooters;
motorized dogs.

Snowmobile

Aerosleigh - homemade version mobile vehicle on snow and ice. Making them is easier than making a snowmobile. Self-propelled sleds are equipped with a chainsaw engine with a pushing propeller and have a chassis with 3 or 4 skis. They can develop high speeds. The only drawback is the inability to drive in hard-to-reach areas, so they are used on a flat surface.

Snow scooter

Snow scooters are controlled sleds for high-speed descent from a steep snow-covered mountain. They are suitable for active recreation for both children and adults. Anyone can make a children's snow scooter. The design is a frame with a chainsaw motor, a built-in seat, controls and 3 metal or wooden skis.

A real snowmobile is quite expensive and not everyone can afford it. Therefore, many craftsmen try to make the most of available materials and tools and collect real miracles of technology. An example of such a miracle is a chainsaw-based snowmobile. At first glance, the problem seems unsolvable, but if you take a closer look, you can easily make a snowmobile or snowmobile out of a chainsaw.

Principle, device diagram, theory, how everything should work out

All work begins with a plan and drawings, which can then be relied upon. Diagrams and drawings will be required in order to take into account all the components and their location, the relationship between each other and the operation of the mechanism as a whole. Pay close attention to the location of each unit, as if you make a mistake, the snowmobile simply will not move.

Work plan:

First, the chainsaw motor is attached to the made frame.
Skis are installed in the steering part of the snow scooter, which are the main element of movement.
Then they are installed steering.
To set the mechanism in motion, it is necessary to install tracks at the rear.
Connect the track disk and the chainsaw motor sprocket.
Finally, the driver’s seat is installed, which is mounted on a specially equipped place.

The main goal is to save money, so it is not necessary to buy all parts of the structure. You can do many of the details yourself. Craftsmen recommend using tracks and skis made from Soviet snowmobile"Buran".

To equip the steering on a snowmobile, borrow the handlebars from a moped or bicycle. The main task will be to properly secure the steering wheel so that when you turn, the skis also turn.

Which chainsaw is suitable for these purposes?

In order to make your own snowmobile from a chainsaw, you will need, in fact, a saw. You can take any brand and model that is in stock. Craftsmen recommend using the Druzhba, Ural or Shtil saws, as they are most suitable in terms of technical characteristics and differ in the quality of their engines.

Friendship

The advantage is the simplicity of the design and therefore it is very convenient to disassemble. In addition, the tool does not have any unnecessary bells and whistles that modern saws can boast of and which only interfere with the assembly of the snowmobile. But there are also disadvantages - the Soviet saw is heavy and outdated.

Chainsaw Friendship

Its technical characteristics are as follows:

power – 1 kW;
weight - up to 12 kg;
engine (two-stroke);
tire length – 45 cm;
fuel (gasoline).

Ural

Excellent technical qualities professional are the best suited for creating a homemade snowmobile on its basis. The mechanism is powerful and efficient, and is also adapted for use in cold conditions.

Chainsaw Ural

Technical data

engine (gasoline, two-stroke, single-cylinder);
power – 3.68 kW;
weight – 11.7 kg;
parameters – 46 x 88 x 46 cm.

Calm

It also has sufficient characteristics to be used in homemade design snow scooter. The most important thing is that the chainsaw has enough power to start the snowmobile. In addition, the Shtilevsky engine is characterized by quiet operation, which will give additional comfort to movement.

Chainsaw Stihl MS 180

What skills are needed?

You don’t need any special skills to assemble a homemade snowmobile, but it is advisable to know how to work with welding and have a welding machine. To use the diagrams and drawings provided, it is advisable to be able to understand them.

Components

Particular attention should be paid to the component parts.

Engine– is the most important part of the mechanism and is selected with special attention. Its condition must not only be working, but it itself must be installed after Maintenance. The gearbox must also be in good condition.

Asterisks– elements for transfer forward movement from the engine. You need to create a tip on the right that is longer than on the left.

The steering is suitable for a scooter, moped or bicycle. The most important thing is to connect the engine to the steering part correctly.

The brake system is not provided for in the presented diagrams, but it can be made. However, first think about whether it’s worth racking your brains over this, because motor sleighs do not develop high speeds.

If the homemade product is planned for children, then as front control you can take ordinary skis, and if you plan to transport more than 60 kg, then use the tracks from the Buran all-terrain vehicle.

Rack

Steering ski: 1 – runner (nylon, sheet s20, from a children’s snow scooter); 2 – spring (normally stretched, from the rear shock absorber of the moped); 3 – spring support; 4 – undercut (duralumin corner 20x20); 5 – spring cover (angle 35x35); 6 – fastening the spring to the cover (M8 bolt with washer); 7 – support lever (pipe 30x30); 8 – spring for fastening the rack-fork to the ski lever (steel, sheet s2); 9 – spring for attaching the support lever to the ski (steel, sheet s2); 10 – axles (M8 bolt, 2 pcs.); 11 – steering knuckle stand (bicycle steering stand with crown and part of the fork); 12 – steering bipod (steel, sheet s4); 13 – fastening of the steering bipod (type M16); 14 – fastening the spring bearing and the lever spring to the ski (M5 bolt with a countersunk head, 7 pcs.); 15 – lever bushing (steel pipe with a diameter of 30 mm); 16 – plain bearing (nylon bushing, 2 pcs.); 17 – stand bushing (steel pipe with a diameter of 30 mm). In the top view, parts 11, 12, 13 of the steering knuckle are not shown.

For the rack, take several 3x3 cm corners and connect them to each other using metal fasteners. To create a platform, you need to attach a sheet of metal to the connected racks. This will be the place to install the gearbox and chain drive shaft.

Don't forget about the seat support. To do this, you need to take a steel module and weld it to the main frame. The module does not have to be large.

Using a beam, connect the front of the frame and the front axle. For these purposes, you can adapt a standard water pipe, which has a radius of at least 1.5 cm. It is clear that this should not be a metal-plastic pipe, but a metal one. Weld the steering wheel bushing at the end, and attach the stand in the middle. This stand will play the role of a subframe for the engine.

Be sure to attach small stiffening ribs in the form of gussets in the places where the racks are attached. This is necessary to strengthen the structure and provide it with a longer service life.

Caterpillar

Description of the caterpillar drawing:

Snowmobile frame with track block: 1 – rear part of the spar (steel sheet s2, with flanges, 2 pcs.); 2 – tension device (4 pcs.); 3 – rear portal (corner 30x30); 4 – middle part of the spar (angle 50x63, 2 pcs.); 5 – bracket-fork for installing the axis of the road wheels (steel sheet s2, 10 pcs.); 6 – middle portal (corner 30x30); 7 – platform for mounting the power unit gearbox and the intermediate speed reducer shaft (steel sheet s2); 8 – scarves (steel sheet s2, 4 pcs.); 9 – front portal (corner 30x30); 10 – front component of the spar (steel sheet s2 with flanges); 11 – axis of tension gears; 12 – caterpillar tension gear (2 pcs.); 13 – axis of road wheels (steel, circle 10, 5 pcs.); 14 – axle fastening (M10 nut and spring washer, 20 pcs.); 15 – spacer bushing (duralumin pipe); 16 – roller (18 pcs.); 17 – bearing assembly (4 pcs.); 18 – caterpillar drive gear (2 pcs.); 19 – caterpillar drive shaft; 20 – drive sprocket of the drive shaft (driven sprocket of the 2nd degree of chain transmission), z=18; 21 – steering knuckle bushing (pipe with a diameter of 30 mm, 2 pcs.); 22 – front axle beam (pipe with a diameter of 30 mm); 23 – scarves, 4 pcs.; 24 – engine stand (pipe with a diameter of 30 mm); 25 – roller tire (rubber ring, 18 pcs.).

It is best to take a ready-made caterpillar from the Buran all-terrain vehicle, having first shortened it.

it is necessary to modify it a little, shortening the workpiece by at least half a meter and connecting it with transport tape. Gears can be made from a sheet of nylon 1.5 cm thick.

Track drive shaft (tension shaft is the same, only position 4, replaced by position 1): 1 – left (along the direction) tip (steel, cylinder 22); 2 – shaft (steel pipe 0.28x20; 3 – flange for fastening the gear to the shaft (steel sheet s4, 2 pcs.); 4 – right (along the way) shaft tip (steel, cylinder 29); 5 – track drive gear (2 pcs.); 6 – frame spar, 2 pcs.); 7 – bearing housing cover (steel, 2 pcs.); 8 – bearing 80204 (2 pcs.); 9 – bearing housing (steel, 2 pcs.); 10 – drive shaft sprocket; 11 – fastening the sprocket to the shaft (M12 nut with wide and spring washers); 12 – key (steel 20); 13 – seal (felt, 2 pcs.); 14 – fastening the bearing housing to the spar (M6 bolt, with 4 sets of screwdriver); 15 – fastening the bearing housing to the spar (M6 bolt with spring washer, 4 sets).

A pipe with a radius of 1.4 cm is used as a drive shaft. A flange with prepared holes for the teeth of the drive wheels is attached to it. At the end of the drive you need to weld trunnion tips.

Law on vehicles does not classify homemade products as transport, therefore the rules traffic one must know because of one's own consciousness, and also adhere to them for the same reason. You cannot drive on public roads where there are a large number of cars.
Do not confuse self-propelled vehicles with snowmobiles. The principle of operation is almost the same, but the snowmobiles differ somewhat in the specifics of their assembly.
You should not hope that the resulting snowmobile will be able to drag loads. Although the power of the chainsaw is high, it will not help with transportation.
It is advisable to install headlights, because in the dark this will be the key to your safety.
