Ural motorcycle engine weight technical specifications

The weight of the Ural motorcycle engine determines the weight of the motorcycle

For decades now, the Irbit plant has been producing Ural motorcycles - reliable and durable units.
Not only our compatriots, but also foreign vehicle users are interested in them. A heavy “Ural” - three decades ago it sounded proud and honorable; even then every second person wanted to become its owner. The plant produces not only the motorcycles themselves, but also spare parts for them. You can look at the spare parts you need in the catalogue, including engines. When choosing, you must definitely pay attention to the engine, they are:

Before buying a motorcycle, each of us will want to study the technical characteristics of the Ural motorcycle engine. The engine is four-stroke, two-cylinder. The engine capacity is 750 cubic centimeters. If we talk about the gearbox, it is a four-speed one and has a reverse gear. The rear wheel has a cardan drive.

The weight of the Ural motorcycle engine determines the weight of the entire machine; on average, motorcycles weigh 300 kg. The service life of a Ural motorcycle engine depends on many factors, but the most important among them is the service life and rules of operation.
Reliability and durability largely depend on operating conditions. Only with good knowledge of the structure of motor vehicles, proper care and timely maintenance can you count on reliable and trouble-free operation of the machine. Depending on the model, the Ural motorcycle has different engine power. For example, the Solo sT model has a power of 40 hp. at 5600 rpm and torque 5.3 kgm at 4000 rpm. And a model like the M62 has a power of 28 hp. Maximum engine power - 55 hp. When choosing a motorcycle, pay attention not only to power, but also to other equally important characteristics.

Continuing the conversation about technical characteristics, we should mention speed. The engine speed of the Ural motorcycle depends on the configuration. The maximum speed you can reach is 110 km/h. Despite its considerable weight, due to the successful selection of the main pair, it quickly picks up speed. And speed is one of the reasons why Ural products are purchased.

This model has certain hidden reserves. Its brakes are hydraulically actuated. They are located in the rear wheel hub. Modern head optics are made in wartime style. The original shape of the fuel tank, turn signals and lights will not leave any motorcycle enthusiast indifferent.

Ural-4320

It all started back in 1961, when the production of Ural-375 trucks started at a plant in the city of Miass (Ural). Despite the fact that this model was constantly modernized, the truck turned out to be not only reliable, but also durable. However, there were also disadvantages, including working with high octane gasoline. They wanted to remotorize cars back in the 60s. The Urals themselves planned to develop diesel, but due to financial problems their plans failed.

That is why the development of a new engine and gearbox began in Yaroslavl. The diesel engine received a serial number and the name YaMZ-740, while the prototype of the truck began to be called Ural-E4320. Until the fall of 1975, several test tractors and flatbed vehicles were produced. However, production began after the documentation was completed. The entire Ural model range.

Maybe it will help someone (don’t take it as advertising, please - this is serious work that has been going on for more than one year)

Historically, we supply components for various pneumatic manufacturers. First of all - for “Litvina”, as well as for “Trekol”. So, this is not the first year we have been collecting information on the weight of spare parts. They themselves hung about 20 thousand pieces of iron in warehouses. About 30 thousand more were found from other sources.

We don’t yet keep it in the public domain in the form of a complete reference book, but you can look at the characteristics of individual parts. In particular, here on the website https://www.avtoall.ru, in our product cards, the weight is marked for the spare part, if it is known to us. (don't take it as an advertisement)

I am interested in this weight as an average statistical parameter. For example, if an SPZ bearing weighs 150 grams, then the same SKF bearing will weigh the same, because I will simply copy the weight from one to the other. Therefore, I cannot say that each figure given is 100 percent verified. For example, a reference book on weights of spare parts from the ZIL plant was given to me as a terrible military secret, and only after 135 requests. And you can’t keep track of the number of typos that manufacturers come across, even though we try and hang the hardware in warehouses ourselves. Again, there is the question of the weight of the packaging container, the density of liquids, and completeness. Well, in general, there are a lot of subtleties in this seemingly simple matter.

Therefore, it somehow doesn’t even occur to me to post such data in the form of a DIRECTORY. This is sewn into the internal database, rather as a GUIDELINE by which you can estimate whether the weight of the cargo will fit into a 3-ton container or whether you need to order a 5-ton container. Well, something like this, in general.

ATTENTION. Update your browser! Our site does not work correctly with IE 8 and older versions.

I read reviews about the motor from the Urals - they are not very good. Now I went outside, tripped over the engine from my previous motorcycle and started thinking. After all, many people made it so that it would be reliable and powerful, but no one tried to make it light. I read somewhere that more than 130 kilograms of force were removed from the snow, albeit with a 170 propeller. Having looked at the spare parts, of which I also still have quite a few, I came to the conclusion that quite a lot of excess weight can be removed from the engine. The first thing you can safely throw away is the flywheel with the clutch, and this is more than 5 kilograms. The second is a heavy and weak generator. Third, replace the heavy lids with fiberglass ones. You can also cut off excess, unnecessary pieces of a thick engine crankcase, plugging the resulting holes, such as the place where the generator is attached, for example, and the partition of the oil pan. (In the last place of the engine, we see the aviation tendencies of BMW - a separate pan in which oil accumulates - there is an oil pump, there is also a second oil scraper ring - between them a certain amount of oil is stored, which lubricates the cylinder walls of some kind time, preventing oil starvation of the piston, in extreme moments.) In general, you can! I'm throwing it away anyway, so I now have a great opportunity to work with a hacksaw and grinder at my leisure. Of course, if someone has already done this, and it turned out to be a mess, then I won’t waste my energy. It is possible to provide a photo report and the weight of individual pieces of iron.

Historical summary and purpose

1977 is considered the year of the first production of Ural 4320 vehicles, the technical characteristics and diagrams of which have not changed much to this day. Their production continues today. The modern generation is equipped with YaMZ diesel power units. They differ in power, but all meet the Euro-4 environmental criterion.

Initially, a gasoline power supply was installed in the car. The device was quite voracious: approximately 40-48 liters were spent per 100 km. fuel. And in 1978, diesel vehicles appeared. Although at first, models equipped with them were produced in very modest quantities. But gradually the company began mass installation of such units on its brainchild.

The design of the car was based on a supporting frame. It guaranteed the car the highest strength. And the model’s impressive cross-country ability was achieved thanks to the all-wheel drive system, single slope tires and short overhangs.

In 1986, the first update of this truck took place. The reforms had little effect on its appearance. There were no significant changes in the engine range; the engine capacity of the Ural 4320 remained the same. The KamAZ-740 was left as the main security force. He retained his leadership until 1993. After a fire at the plant, supplies of this engine ended. It was replaced by products from the Yaroslavl concern. These are the engines: YaMZ-238 and YaMZ-236.

The first models equipped with the YaMZ-238 were characterized by a long compartment for the security forces. And variations with YaMZ-236 have not changed their previous forms. But since about 2004-05, all models have acquired an extended engine compartment.

In the mid-90s, Ural 4320 cars acquired a new bumper, which also had headlights. Plastic plugs were mounted to the wings in the former position of the headlights.

And the production of versions with a bumper continued only for the needs of the army. Since 1996, the company began producing lightweight modifications on two axles.

Modernization

The next modernization of the truck took place in 2009. The Ural has acquired a transformed cabin. A fiberglass lining was installed in front of it. The shape of the car turned out to be more streamlined. On some versions, the standard radiator grille was replaced. The classic grille had vertical lines, while its replacement had horizontal lines.

Some models began to be equipped with the Iveco “P” cabover cab. Its difference from the previous cockpit is the presence of a rounded tail. The previous security forces were replaced with serious diesel products YaMZ-536 and YaMZ-6565, which meet Euro-4 standards.

Since 2014, the Ural 4320 tractor has been transformed into the Ural-M group. Many of the car's parameters have been preserved.

A year later the car was modernized again. The result of the reform was the Ural Next series. Its features:

Weight, service life and power - technical characteristics of the Ural motorcycle engine

At one time, the brainchild of the Irbit plant was in great demand. An excellent assistant in agriculture and serving as an excellent alternative to a car, the Ural had the ability to move on any road surface. The plant has currently stopped producing motorcycles. This happened due to a banal economic recession. In recent decades, the assembly of the Ural motorcycle engine has become an analogue of the German BMW-R71, as well as the stubborn competitor of the Dnepr.

The engine of the Ural motorcycle, the technical characteristics of which can easily compete with the new generation motorcycles, is subject to severe wear and tear. Therefore, owners often have to go through all the parts themselves and replace them.

The Soviet bike is considered a heavy motorcycle intended for rural work and transportation of goods. At the same time, it has relatively small but sufficient indicators. The Ural motorcycle engine on the Solo model produces 40 horsepower . And with boost you can achieve 55 hp. The maximum speed of the bike is 110 km/h. For such power, this is a rather modest figure, because the speed is greatly influenced by the mass of the motorcycle. However, the acceleration is quick and the bike's dynamics are very pleasant for the rider.

The engine capacity of the Ural motorcycle is 745 cm3, which makes it one of the largest in Russian production. In this case, the torque reaches about 4000 rpm .
Such engines are typical for engines with gearboxes, rather than for boxer engines.

Ural 4320

Technical characteristics of the URAL 4320 - a truck produced at the plant in Miass. It is mainly used in the military, but is often used in other areas: utilities, construction, commercial. Often they try to use this machine in forestry and mining activities. Here the car is an excellent assistant due to its strong cross-country ability and ability to transport heavy loads.

The Ural 4320 has one key advantage over its analogue competitors: it uses a 6 x 6 wheel arrangement. Thanks to this, the car has powerful cross-country ability. The all-wheel drive version easily handles large holes, difficult climbs, wetlands and ditches. This machine is especially useful during snow drifts and spring “porridge”.

How much does a Ural motorcycle weigh?

From the very beginning of production, the Irbit motorcycle plant produced heavy-duty mopeds. Regardless of how much the Ural motorcycle with sidecar weighs, it has good power and cross-country ability. This unit is an excellent assistant in agricultural work. The average weight of the Urals is approximately 200-250 kilograms without a stroller. A passenger trailer adds about 100 kilograms to the total weight . This weight makes it very stable and dynamic on the road, providing good cross-country ability in difficult road conditions. It is not so important how much a Ural motorcycle weighs without a sidecar as its ability to transport cargo. It can withstand a load of more than 150 kilograms. This is facilitated by a fairly powerful engine, designed for transporting people and various heavy objects.

Only the Dnieper can compare with such performance. True, there are also disadvantages. When the bike is heavily loaded, fuel consumption increases significantly. Some owners overload the moped with a load that exceeds its own weight. In such situations, driving the Ural becomes very difficult, and in turns it behaves extremely unnaturally. So before you throw in that extra sack of potatoes, think about how to corner on an overloaded motorcycle.

In addition, when driving off-road, excess weight can cause slipping in soft ground. In turn, slipping can help loosen the soil, and you will simply stand still. If you don't have an assistant at hand, getting out of the sand trap will be very difficult. Therefore, try to follow the operating requirements and not exceed the maximum declared capacity to carry cargo.

Motorcycle air filter K 750

The air cleaners of the K 750 motorcycle were installed directly in the gas tank, which will change the design of not only the air cleaner itself, but also the fuel tank with air ducts and the motorcycle frame.

On earlier motorcycles, air cleaners were mounted on the gearbox housing.

An air cleaner located in the gas tank has a number of advantages over an air cleaner installed on the gearbox. The main advantage is that the air cleaner located on the fuel tank is located in a zone of less dusty air on Ural motorcycles.

This arrangement of the air purifier ensures longer and higher-quality air purification for preparing the working mixture. The service life of the engine increases. Fuel consumption is reduced. The air purifier itself is washed less often. The operating principle of both air purifiers is the same.

Below are comparative indicators of these air purifiers. The K-750 engine is equipped with two K-37 A carburetors.

Repair and tuning

Close to 100% maintainability and huge scope for tuning are the strengths of the Urals . But all this will require a garage, a lot of tools and even more free time.

Repair

The Ural motorcycle requires attention often, and breakdowns happen from time to time. To avoid them, the bike needs to be given the closest attention, often servicing the cardan, adjusting valve clearances, setting the ignition correctly and performing other service operations.

Spare parts

They are available and inexpensive, but the quality varies from acceptable to extremely poor. The mediocre quality of spare parts is one of the reasons for frequently occurring problems.

Tuning

It is the old Urals that most often act as donors for novice customizers due to their low cost. They make a lot of things out of them, from trikes and custom choppers to scramblers and even sportbikes . The results sometimes smack of rural charm, but there are also some very worthy customs.

Advantages and disadvantages

The strengths and weaknesses of the model are obvious, and they are inextricably interrelated. The archaic and outdated design half a century ago is unreliable, but thanks to its simplicity bordering on primitivism, it is easy to maintain and repair.

Advantages

• Quite high power compared to most other Soviet motorcycles.
• Huge scope for tuning . What craftsmen don’t install on Urals, from the injector to the fifth gear!
• Total maintainability . The bike can be repaired no matter what happens to it. Always.
• Undemanding to the quality of gasoline.
• Short service intervals . Valves require frequent adjustment.

Flaws

• The deplorable technical condition of most copies.
• Low quality components , which leads to frequent minor breakdowns.
• High fuel consumption .

Motorcycle Ural M 72

The Ural M 72 motorcycle, in terms of its design and performance qualities, belongs to the category of heavy road motorcycles of the 750 cm cube class.

Produced since 1942 by the Irbitsky and since 1952 by the Kyiv motorcycle factories.

Over the many years of its existence, it has shown itself at its best. A large reserve of engine power in all gears, a large permissible load, significant speed, ease of control, ease of care and maintenance, great wear resistance - all this attracts motorsports enthusiasts to it.

Valuable qualities are due to its successful layout and thoughtful design.

Shock absorption of sprung wheels provides comfort and significantly reduces driver fatigue during long driving.

Reliable lighting allows for fast driving in the dark.

Currently, the M 72 motorcycle has been discontinued, but more advanced models have been created on its basis.

Price and options

For the Ural-4320 car with the latest cabin and the same YaMZ-236NE2 power unit (230 horses) you will need to pay 1,710,000 rubles. For the extended Ural chassis and increased load capacity, you will have to pay 1,880,000 rubles. A flatbed model of the Urals, covered with an awning and with a winch, the same engine for 230 horses, costs 1,790,000 rubles. Finally, the Ural-4320 flatbed, with a long wheelbase and a Yaroslavl engine with 230 horsepower, can be purchased from 1,950,000 Russian rubles.

Owner reviews

A powerful unit with decent performance characteristics, in the right hands can live forever, or as long as there are spare parts. Considering how many opposition pieces were riveted in the USSR, there is every chance of passing it on to one’s grandchildren as an inheritance. Anyone who says that this is a bad spender simply does not know how to handle it. Igor, Smolensk.

I started my two-wheeled life with a stroller, like many, and rode until I earned money for an old Honda Steed. When I sold the stroller and switched to a Japanese one, I drove it once and realized that when I go to hell, part of the torment will be credited to me there))) Ivan, Tver.

In stock condition, it’s trash, killed by a disregard for it. With the right approach, the motorcycle is reliable and durable, it will go anywhere, there are enough horses and torque, it can be repaired with a hammer and a screwdriver, and it will eat any gasoline. If you put survivability at the forefront, then Uralei has no competitors except old Harleys, but here the price of the issue is completely different. Anton, Murom.

Power apparatus

The latest modifications of the Ural 43 20 include several versions of V-like diesel power units created at the Yaroslavl enterprise. The following models have become the most common (technical characteristics of the Ural 4320):

These devices were cooled using liquid. They received food thanks to high-pressure fuel pumps.

At the request of the customer, specialists can supply the YaMZ-7601 device. Its power is 300 hp.

Conclusion

Many bikers started out as boxer road veterans found in grandpa's garage. Ural M 67 is an excellent learning desk that will teach you not only how to ride, but also how to maintain a motorcycle, and of course, how to repair it. And after this fiend of the Soviet motorcycle industry, you will be able to handle any other bike! This is the case when starting with a structurally simple motorcycle would be a good idea, especially since a fair number of them can always be found on the secondary market, and for very modest money.

Specifications

Modifications

There are a considerable number of Ural-4320 off-road trucks, and each of them has its own feature:

It turns out that in different versions of the Ural-4320, the engine power was radically different. There was a particularly significant appearance in 2009 of a new version of the truck, where the cabin was equipped with additional comfort. For example, the hood was made of fiberglass. Moreover, a stylish unique plumage appeared. Starting this year, the auto company is worried not only about the off-road properties of the truck, but also about the convenience of staying in the driver’s cabin, which has not received so much attention before.

It is worth saying that when assembling the truck, the engineers thought about the person who would drive the Russian car. The steering wheel was not without a hydraulic booster. The cabin had a pretty good heater. The driver's seat is adjustable in three directions - height, length and adjustable backrest tilt. There are headrests and armrests, making the ride more comfortable. We started installing seat belts.

The interior began to be made from materials that provide good noise and heat insulation. The instrument panel has a convenient location. All sensors and meters are easy to read, and the necessary buttons and switches can be used without leaving the driver’s seat. There is also a rather large and rational glove compartment, and a shelf for storing papers and other things and property. Under the passenger seats there is a tool chest. It is possible to equip the car with a sleeping place.

Engine m 72

The engine of the Ural M 72 motorcycle is a two-cylinder, four-stroke engine; according to its design features, it can be classified as a forced road-type engine (despite the lower valve timing mechanism), since its compression ratio, speed and power are quite high. The engine on heavy motorcycles from the Irbit plant has an opposite arrangement of cylinders in a horizontal plane, which ensures good balancing of the inertial forces of the crank mechanism and reliable cooling. A gearbox is attached to the engine, connected via a clutch.

The cylinders are cast from alloyed or modified cast iron. The valve boxes are cast integrally with the lower cylinder support flanges. The left cylinder is moved slightly forward in relation to the right one. The cylinder heads are cast from aluminum alloy and have double ribbed bottoms for better cooling of the cylinders of the Ural M 72 motorcycle engine. An asbestos-metal gasket is installed between the head and the cylinder.

The pistons are cast from a special aluminum alloy, which contributes to their better cooling. Two compression rings are installed in the upper grooves of the pistons. In the lower groove there is an oil collection ring. The lower groove has through cutouts designed to reduce heat transfer from the head to the piston skirt and to remove oil removed by the oil collection ring from the cylinder walls. The piston rings are made of special cast iron. All rings have straight locks, the gap in which in the working position is 0.25-0.45 mm.

The connecting rods have one-piece heads. Bronze bushings are pressed into the small heads, and single-row roller bearings with cages are inserted into the large ones. The small head is connected to the piston using a floating piston pin. The rollers of the large head roll along the surface of the crankshaft journal, which has two elbows with crank radii of 39 mm. The crankshaft assembly with connecting rods is an integral unit, since its disassembly and reassembly is impossible without special tools.

The durability of this unit is guaranteed by the factory within 15,000 km. When assembled, the shaft is installed in a one-piece crankcase on two ball bearings. To mount the engine to the motorcycle frame, there are special bosses with holes for through bolts in the lower part of the crankcase.

Fault Inspection

When inspecting the parts, you should check the ease of movement of the forks along the rod. Condition of fork stays and ring grooves in movable couplings. The amount of axial movement of the forks in the groove of the engagement couplings.

The following malfunctions may occur in the trigger mechanism: - wear, crushing or chipping of the pawl; — jamming of the pawl pusher; — breakage of the pawl spring; — bending the ends of the return spring of the starting pedal; — damage to the working end of the buffer pin; — cracks in the starting lever; - wear of the oil seal.

Controlling a motorcycle Ural M 72

The Ural M 72 motorcycle is controlled by mechanisms located on the steering wheel and having a manual drive.

In addition, there are a pair of brake pedals and a gear shift lever.

Manual control mechanisms include: throttle handle, front brake lever, clutch lever, combination shifter.

The gas handle, located on the right half of the steering wheel, is connected to the carburetors using flexible cables. To increase the engine speed, you need to turn the throttle towards yourself, and to decrease it away from you.

The front brake lever is hinged on a bracket on the right side of the steering wheel and connected to lever 24 by a flexible cable. To brake the front wheel, the front brake lever must be pressed against the steering wheel handle.

The clutch lever is located on the left handlebar and is connected to the clutch lever 19 using a flexible cable. To disengage the clutch, the clutch lever should be pressed against the steering wheel handle.

The combined shifter is designed to force the ignition advance, switch the headlight light and turn on the electric signal.

Transmission

On the M 61 and M 62 a clutch is installed, similar in design to the K 750 clutch, but the K 750 clutch is adjusted by one adjusting screw screwed into the clutch release lever, and the M 61 and M 62 clutches by two screws: an adjusting screw in the release lever and a shell stop screw cable screwed into the crankcase bracket.

Cardan and final drive diagram.

The power transmission gearbox of the Ural M 61 and M 62 motorcycles is the same in design as the M 72. True, there is not much difference, the M 62 differs from the M 61 only in the design of the shift couplings, the secondary shaft and its gears.

The cardan transmission is identical in design to the K750. The rear gears of the M 61, M 62 and K 750 are the same, with the exception of the crankcase covers: for the M 61 and M 62 motorcycles, the crankcase cover is made integral with the right suspension bracket, and the cover has an oil filler hole.

Speed ​​indicators

The maximum speed of the Ural Gear Up 2021 2WD is 110 km/h, fuel consumption remains at 7.5 liters per 100 kilometers in the combined cycle.

Ural City 2021 is not inferior in terms of dynamic characteristics: the maximum speed is also 110 km/h, fuel consumption is 7 liters for every “hundred” of kilometers traveled. Riding comfort at high speed is ensured by a front wheel suspension with two spring-hydraulic shock absorbers and a pendulum-type rear wheel suspension with two spring-hydraulic shock absorbers. Both are load adjustable.

Let's sum it up

Model 4320 Ural became a successful successor to the gluttonous 375 D, which consumed up to 70 liters of gasoline per 100 km. Even today, this car evokes some kind of wild delight by its appearance alone. It can transport absolutely any cargo and travels where the road is forever closed to many SUVs. The 6x6 wheel arrangement and simply fantastic ground clearance of 360 mm lays the foundation for producing the 4320 Ural for many years to come.

The design of the remaining electrical devices and units of the Ural M 72 motorcycle is given in the description of the electrical equipment of the K 750 motorcycle.

The required driving tool is shown below.

Electrical equipment

M 67-36 “Ural” retained the 12-volt electrical equipment system implemented on its predecessor. It should be noted that up to the M 67, 6-volt electrical equipment was used on IMZ motorcycles. Increasing the voltage made it possible to equip motorcycles with modern lighting equipment of international standard at that time. In addition, they introduced a more powerful 150-watt generator G-424 with a current regulator PP-330. Otherwise, the electrical equipment remained the same.

Topic: Main differences between “Ural M67-36” and “IMZ 8.103-30 Ural”

The main differences between “Ural M67-36” and “IMZ 8.103-30 Ural”

Batin Ural In accordance with the invoice, the Ural motorcycle was sold to Mikhail Danilovich Raznoschikov on February 2, 1985. Since then he has become part of our family. An assistant in all matters.

And so, in the fall of 2021, I decided to take him to my place, in Bryansk, for a little feather cleaning.

And already in the winter of 2017-2018, while sorting out a bunch of wires, I made an unexpected discovery.

All my life, looking at it, I thought it was a Ural M67-36. At least that's what the instruction manual that came with it said. Every time I climbed into it, I saw the flyleaf.

And there was even an application for the Ural M67-36.

I never noticed that it is for IMZ 8.103-30 Ural, 1985.

It was from this application that I learned the main differences between “Ural M67-36” and “IMZ 8.103-30 Ural”

“This appendix is ​​an addition to the manual for the care and operation of the M67-36 URAL motorcycle.

The manual briefly describes the design and operation of new units and components.

For all other issues related to the operation of the motorcycle, the manual for the care and operation of the M67-36 motorcycle remains.

This model, in contrast to the previously produced one (M67-36), has the following new units and components installed: - a motorcycle frame with inclined installation of spring-hydraulic shock absorbers (according to A. KHALTURIN, deputy chief designer of IMZ. The motorcycle differs from the previous model in improved rear suspension The frame design has been changed, the angle of inclination of the rear shock absorbers has been increased, which contributes to more efficient operation of the rear suspension and, ultimately, increased comfort);

FAQ

• How interchangeable are their spare parts with the Urals? Many components fit from one brand of motorcycle to another. In this case, spare parts from, for example, a gearbox may not be suitable, but you can replace the entire assembly.
• In Russia, does it make sense to buy the Dnieper, or is it better to look for the Urals? I am looking for a motor for restoration and restoration. Why not? In the USSR, a variety of oppositions were distributed throughout the country.
• Can the cylinders on the MT 10 36 engine be bored? Yes, the quality of the metal there is good, the alloy is not at all porous, and cavities are rare, so it can be bored. At your own peril and risk, of course.

How does a gearbox work?

On the secondary shaft, the gears have splined rims, with which the gear clutches alternately engage, moving along the outer splines of the secondary shaft couplings. Gear shifting occurs using splined couplings, the movement of which is ensured by the gear shift fork. The forks are not interchangeable and are driven by a sector welded to the shaft. There are two grooves in the sector where the fork spikes fit. Using the manual gear shift lever, the sector is set to one of five possible positions.

Description

The Ural motorcycle engine is a two-cylinder, four-stroke, air-cooled power unit. It is equipped with an electronic fuel injection system (injector) developed by the engineering company ElectroJet Inc.

The main power element of the motor housing is the crankcase. Structurally, it consists of:

• the crankcase itself;
• distribution box covers;
• front and rear bearing housings;
• pallet;
• front cover.

The crankcase is cast from high-strength aluminum alloy. Pistons and the junction box cover are also made from it. The cylinders that are installed in the crankcase are cast from special cast iron, which has increased strength. Their internal surfaces are honed before installation, bringing the surface cleanliness to almost a “mirror state”. The materials from which the pistons and cylinders are made during operation form a good anti-friction pair that is not subject to severe wear.

In addition to the parts of the cylinder-piston group, a crank mechanism, a gas distribution mechanism, etc. are installed inside the crankcase and on its outer walls. In this case:

• the camshaft is installed in the upper part of the crankcase on bearing supports, and the pushers are located on its two sides;
• the junction box cover is attached to the front wall;
• the oil filler neck with a plug equipped with a dipstick is located on the left wall;
• the crankshaft is mounted on main bearings installed in the walls;
• From below, the crankcase is closed with a special steel pan, which is used as a reservoir with engine oil.

The assembled engine is installed on the motorcycle frame and secured to it with two studs.
