Installation of a Chinese engine on a uniaxial tractor Ural

With a Chinese engine

The standard motor of domestic production is not suitable for all owners of Ural motoblocks. In search of a solution to the problem of capacity at an affordable price, they turn their attention to Chinese products. Chinese manufacturers offer products with a capacity of 10, 12 and more horsepower at a fairly low cost, available to almost every farmer.

Thanks to more powerful Chinese engines, the owner of the walk-behind tractor has expanded opportunities for modifying it to fit his needs. For example, they are used as quite powerful snow blowers.

How to convert a single-axle tractor Ural to a Chinese engine

I have such a question. and if, in the process of installing a Chinese motor, so that the rotation of the cutters is in the right direction, turn the gearbox so that the pulley comes out to the left side. Accordingly, put the engine back to front. Do I understand correctly? If you sell, then what can prevent this? And why don’t others do it ?

Zhenya Zhekin and the meaning of such alteration. It is necessary to cut off the entire gearbox. digest again to the frame. Among other things, after the overturn, the gearbox also starts working backwards. that is, the back becomes frontal. The only thing that needs to be guessed when reworking. this is weight distribution.

Here I found a video ru-TV.org/TV/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5gSmo5y_Lik.html

what kind of oil do you fill in the engine? I HERE FILLED MINERAL WATER 15W40, I’m AFRAID As if I DO NOT REGRET about such a situation, I RUNNED IN OIL on this matter. WHERE THAT 5-6 MOTOR HOURS THE MOTOR WORKED ON THE MINERAL WATER, CAN IT BE BADLY REFLECTED ON THE ENGINE? THANK YOU

I won’t say about oil, my father uses a walk-behind tractor

I also bought a Lifan engine without a gear. The shaft is short, the engine will have to be shifted to the side. How did you solve the myth question. I can’t learn from the video?

The platform for the engine is homemade, at first we fixed it on the frame and then the engine was adjusted.

What model of the Lifan motor? Is there a reducer of course?

I don’t remember the model, there is no gearbox and the power is 6 or 6.5 hp.

threw out their own motor, purchased a large Lifanshiv (blue), made a motor mount from an 8mm plate. Because the rotation goes in the other direction, rearranged the control knobs. That seems to be all. I forgot to sell, the tension rollers had to be wise to others.

As I know, the blue pulley (Neva) has both V-shaped streams, and the native pulley has one rectangular stream, it is for an inverted belt for reverse. Is reverse gear arranged in your image? You turn the reverse belt over, or it works randomly. Is the reverse drive stable??

How to operate

The maintenance manual for the Ural motoblocks of the UMP and UMB series is not much different from the operating instructions for any other similar unit, and in many respects is even simpler than them. And first of all, the device is prepared for operation. For preparation, several extremely simple and universal actions are performed:

• conduct a general inspection of the walk-behind tractor;
• check for fuel or oil leaks;
• set the gearbox to neutral;
• measure the levels of fuel and oil in the respective tanks;
• if necessary, add working fluids;
• check the operation of the engine by turning it on.

Motoblocks Ural have the greatest maneuverability in comparison with their competitors

If no problems were identified at the preparatory stage, work begins. For what:

• switch the engine to low speed;
• turn off the clutch mechanism;
• include the required speed on the gearbox;
• release the clutch release lever, which leads to an increase in speed and the start of movement.

But before starting the permanent operation of the unit, it is run-in. Thanks to this procedure, you can significantly extend the life of the Ural cultivator. It is carried out not only immediately after purchasing the device, but also after any prolonged downtime.

• Start the engine at idle speed. While the gearbox must be in neutral.
• The unit operates in a similar mode for the first five hours, without load.
• After their end, the device is loaded at half the power and so it works for the next 25 hours.
• Over the next 30 hours, the owner gradually increases the load on the car until it reaches its maximum.

Important! Do not run in without first adjusting the belt tension.

Ural with Lifanov engine

Lifan is China’s largest cultivator motor manufacturer. Therefore, it is the models of this company that are most often discussed when replacing the motor with a Chinese one.

Characteristics

We give some data on the walk-behind tractor.

• dimensions of the walk-behind tractor: 1560/790/1050 mm;
• ground clearance 270 mm;
• cylinder volume 0.475 l;
• weight. 125 kg;
• with a fuel tank volume of 6 liters, fuel consumption is less than two liters of gasoline;
• four-stroke engine with right-hand rotation, single-cylinder, uses gasoline with any octane number, reacts well to gas;
• air-cooled;
• the battery shows high charge rates.

Advantages of the Ural walk-behind tractor:

• when the unit weighs more than a centner, it is not necessary to additionally press on the handles with its own weight, which makes it easier to cultivate the land;
• there are numerous opportunities for self-improvement and design upgrades;
• high resource indicators of the engine;
• air filter does not require replacement of gaskets.

At the same time, the following disadvantages were also noted:

• Frequent leakage of lubricant at the joints of the engine / gearbox;
• you have to check the oil level frequently;
• the gas distribution mechanism leads to an increase in the consumption of gasoline and engine oils due to design features;
• not recommended for long journeys with a load (low speed).

Engines UMZ-5B and its variant UMZ-5DU-B have the following characteristics:

• four-stroke, power up to 5.4 liters. from. (more than 3.5 kW);
• equipped with a two-stage gearbox with a gear ratio of 1 to 6 or 1 to 2.91;
• one cylinder;
• forced cooling.

The UMZ-5DU-B model differs in that its gearbox is single-stage and its gear ratio is 1 to 6, and a ratchet is not installed on the gearbox shaft.

As an alternative to Ural engines, if it becomes necessary to replace it, they often choose imported products from the Chinese manufacturer Lifan (Lifan).

Lifan was founded in the early 90s of the twentieth century and today is one of the most famous large companies in the automotive market in our country. In addition to engines, Lifan also produces other motor vehicles with an optimal price-quality ratio. The products are certified, and each product must be accompanied by a technical passport and operating instructions.

Lifan presents different types of engines on the Russian market. One of the most important characteristics when choosing an engine is the installation dimensions, since they do not always correspond to Russian standards.

Another important characteristic is engine power, since in most cases Lifan engines have 6.5 liters. from. against 5 liters. from. at the “Ural“.

Disassembly itself is not particularly difficult and is performed in a couple of stages even by a specialist with little or no experience.

• The old engine is removed from the fastening connectors using standard open-end wrenches.
• First, disconnect the fuel and oil lines, if any.
• Next, remove the centrifugal regulator.
• Sometimes, at the stage of installing a new engine, it is necessary to use gaskets, but with the correct selection of sizes, this is not necessary. The easiest way is to fit an adapter plate with holes for fixing.

uniaxial tractor “Ural

Motoblocks “Ural-UMP-5V” first began to be sold in the country just before its global redistribution at the dawn of the 90s of the last century. Since motoblocks, as a convenient and cheap technical means, were needed by many, so it became very popular in the USSR. In just a few years, its sales reached 150 thousand units. Such popularity of the walk-behind tractor was facilitated by the optimal combination of its characteristics.

The developers were able to combine the high performance of the walk-behind tractor, which was achieved by a five-horsepower gasoline unit that accelerates it to a speed of 15 km / h, combined with battery power sufficient to process up to 2 hectares of arable land. In addition, the unit could carry loads of up to half a ton in weight.

The walk-behind tractor has a wide adjustable ground clearance, which allows the device to be operated on different types of sites. But it should be noted that the basic model of the “Ural” is not particularly versatile. It can only transport goods and cultivate the soil. Mowing grass, removing garbage or snow using attachments will not work with this technique. such opportunities are not provided. But if you independently redo the structure by adding the necessary fasteners, then you can expand its functionality.

The model is implemented according to the scheme of power transfer to the wheels by means of a differential. Some modifications use foreign high-power engines, but domestic versions are the most popular due to the availability of spare parts, proper documentation and durability of operation.

With ZiD engine

The UMZ-5V motor is not the only version of the domestic engine installed on motor cultivators manufactured by the Bashkir plant. The ZiD-4.5 became an alternative. The reason that he was so easily able to replace another model is their great similarity.

A feature of the motor is the presence of a pulley and an asterisk for driving the chain on the crankshaft. In this case, the transmission itself is located on the gearbox side, while the pulley is on the flywheel side. Lubrication method. spraying, for which oil is supplied from a 1.5-liter sump by a plunger pump.

The engine is driven by a belt, and the gears are shifted using a handle. The transmission itself has two speeds, which are controlled in the same way as on the UMZ-5V.

Testimonials

I bought a Ural single-axle tractor to work on a plot of slightly more than half a hectare. What can I say? It is immediately clear that this is a domestic technique and it does not look newfangled at all. But, at the same time, it performs its function entirely. I have heavy ground. But, the cultivator has not broken even once in three years! I adapted it for other works by buying all sorts of awnings. In general, if you are looking for something cheap and powerful, and appearance is not the main thing for you, this is the solution for you.

A single axle tractor like this is what a Middle Lane farmer needs. A minimum of problems, sufficient power for plowing, repaired at a time. What else does? Yes, the model is a bit dated. But, reliability and efficiency are more important.

uniaxial tractor Ural with UMP 5V engine

A feature of the Ural walk-behind tractor model with an UMZ 5V engine is the ability to process clay and other heavy soils without losing efficiency. In combination with the ability to work in almost any climatic conditions and maintainability literally on the go. this made the model one of the most popular among domestic gardeners.

The unit belongs to the uniaxial category. Its track is quite wide, but it can be easily adjusted for operational needs. You can set the required value, both based on the characteristics of the soil and the workflow. The package includes a 1.5 liter oil tank.

The main purpose of such a motor-cultivator is the processing of a land plot with the aim of further planting selected crops on it. Such work as transportation of goods, haymaking, garbage and snow removal is possible only after the installation of attachments. At the same time, there is no shortage of models of the latter.

General technical characteristics of the Urals UMP-5V:

• weight. 120 kilograms;
• air cooling of the motor;
• 82mm cylinder;
• gasoline engine, 5 horsepower;
• fuel tank, 6 liters.

The rather large dimensions and massiveness of the car in the eyes of many are its main drawback. Because of this, it is quite difficult to transport it over long distances. Despite the fact that it is suitable only for processing medium areas. An important disadvantage is the noise, which requires the use of ear protectors.

Replacing the engine on the Ural walk-behind tractor with a Chinese one

Chinese engines are convenient for many owners of these units due to their ease of installation. To replace the standard domestic motor of the Urals with products from the Middle Kingdom, there is no need for any special alterations. It is enough to install additional cross members.

These cross members, made of metal, are attached to the frame of the device using welding or bolts. The first method is considered more reliable. You will also need to install homemade pulleys in the clutch. The reason for this is the increased crankshaft speed of Chinese motors.

Description

The description of the Ural Patriot walk-behind tractor is worth starting with the fact that this machine was assembled by a defense enterprise from Bashkiria called JSC TsMPO. This is one of the best examples of the conversion of military production to civilian rails.

Motoblocks Ural have a low price and high quality

The single-axle tractor gained its popularity due to its ease of operation and high maintainability. This car can be repaired on the go, and there are no problems with access to spare parts.

• cultivate plots with an area of ​​up to a hectare;
• the possibilities are not limited only to soil processing. it is able to remove snow and transport goods using the proper attachments;
• the transmission of the device is equipped with four gears;
• due to a maximum speed of up to 15 kilometers per hour, it is well suited for transporting goods in conditions of poor or no roads;
• has increased stability due to the width of the wheelbase;
• it is allowed to adjust the track based on the operating conditions, which significantly increases the efficiency of the unit.

Attention! Models of the Ural walk-behind tractor are equipped with both domestic and foreign engines. The choice of this or that option entirely depends on the preferences and budget of the consumer.

In this video, we will review the Ural walk-behind tractor:

Ural with Lifanov engine

Lifan is China’s largest cultivator motor manufacturer. Therefore, it is the models of this company that are most often discussed when replacing the motor with a Chinese one.

Specifications

Due to their parameters, Ural cultivators remain popular from the very moment of their appearance on the market and their technical characteristics have largely become an example to follow from other manufacturers.

It is worth noting that the very first model Ural UMZ-5V is quite heavy. It weighs as much as 120 kilograms, despite the fact that it is intended for processing plots whose area does not reach a hectare. A lot of physical strength is required to work with the unit.

On the flagship models of the Ural walk-behind tractor, there is a domestic gasoline carburetor single-cylinder engine with four strokes and a power of five horsepower. Although the model of the domestic engine itself is quite old, it is still very reliable. In particular, it is very resistant to low temperatures. And air cooling allows the walk-behind tractor to work in hot weather, since its motor does not overheat.

The brand of gasoline for this unit does not matter. it is capable of working with almost any gasoline fuel. It is extremely economical in fuel consumption: having a tank with a volume of only six liters, it consumes no more than 2 liters per hour.

The new model of Uralov. Ural UMB-K Argos. It retained the best technical features of its predecessor, but thanks to some improvements it became suitable for processing large areas. In particular, the engine power has increased, which in this device is 8 horsepower, instead of 5.
