Advantages of the Ural tiller:

  • when the unit weighs more than a centner, it is not necessary to additionally press on the handles with its own weight, which facilitates the tillage
  • 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:

Honda C90 cub Lifan Engine Conversion ready for North Coast 500

  • 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 the 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 our most famous large companies in the automotive market. In addition to engines, Lifan also manufactures 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.

Lifan offers several lines of gasoline engines: 168F, 168F-2, 177F and 2V77F.

Ruler 168F:

  • four-stroke;
  • power. up to 5.4 liters. from. (more than 3.5 kW);
  • 1 cylinder;
  • cooling. forced;
  • the crankshaft is located at an angle of 25 degrees;
  • cylinder. 163 cm3;

tiller “Ural

Tillers “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 many people needed tillers as a convenient and cheap technical means, therefore it became very popular in the USSR. In just a few years, its sales reached 150 thousand units. Such popularity of the tiller was facilitated by the optimal combination of its characteristics.

The developers were able to combine the high performance of the tiller, which was achieved by a five-horsepower gasoline unit that accelerates it to a speed of 15 km / h, combined with the power of the batteries, 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 tiller 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 the most popular are domestic options due to the availability of spare parts, proper documentation and durability of operation.

Selection and installation of the engine on the Ural tiller

All gardeners and gardeners prepare their plots with the beginning of seasonal work. Many people use tillery for plowing the land. But not everyone can buy the latest models and continue to use the legacy of the Soviet Union. One such unit will be discussed today.


According to their traction characteristics, the tillers are divided into classes.

  • The light class includes devices with engines of less than 5 liters. from. they are used to treat areas less than 0.02 hectares.
  • Medium tillers with engines less than 9 hp. from. used on plots up to one hectare.
  • Heavy, with a capacity of up to 18 liters. from. cultivate the soil on plots of up to four hectares.

we can say that today’s market offers different tiller engines, both Russian and imported, and in many cases they are interchangeable.

How to install the Lifan 168f-2 engine on the Ural tiller, see the video.


a tiller with a Lifan engine has the following advantages:

  • stability of work;
  • high quality;
  • reliability;
  • low noise and vibration;
  • small overall dimensions;
  • the use of a cast-iron sleeve to increase the service life;
  • ease of operation and maintenance;
  • large margin of safety;
  • long term of service;
  • affordable price.

All these qualities distinguish Lifan engines from other engines.

How to install a Lifan engine on a tiller

Each model and class of tiller has its own engine. Consider the following examples:

  • Tiller Ugra NMB-1N7 with Lifan engine corresponds to the 168F-2A version in terms of technical characteristics.
  • Tiller Salyut 100. version 168F-2В.
  • Ugra NMB-1H14 middle class. Lifan 177F engine with 9 hp. from.
  • Agat equipment with a Lifan engine can be equipped with the 168F-2 and Lifan 177F models.
  • An eye with a Lifan 177F engine when aggregated with attachments will work better and more efficiently. Model 168F-2 with a capacity of 6.5 liters. from. also suitable for tiller Oka MB-1D1M10S with Lifan engine

The engine can be installed on Tilleri Ural, Oka, Neva according to the following algorithm of actions:

  • Remove the protective cover from the old engine, belts, pulley, while unscrewing the bolts.
  • Remove the air-purifying filter to disconnect the throttle cable.
  • Remove the engine from the tiller frame.
  • Install the motor. If necessary, a transition platform is installed.
  • A pulley is attached to the shaft, the belt is pulled for better track performance, adjusting the position of the motor.
  • Secures the transition platform and engine.

The user must take care of the mounting hardware when installing the motor.

Adjustment of valves

Valve adjustment is a necessary procedure when servicing the motor. According to the regulations, it is carried out once a year and consists in setting the optimal clearances of the intake and exhaust valves. Their permissible value for each motor model is presented in the technical data sheet of the unit. For standard tillers, they have the following meanings:

  • for the inlet valve. 0.10-0.15 mm;
  • for the outlet valve. 0.15-0.20 mm.

Gaps are adjusted using standard styli 0.10 mm, 0.15 mm, 0.20 mm.

With the correct setting of the intake and exhaust valves, the motor will run without noise, knocking or jerking.

Lifan engines for tillers: how to remake, install imported to the Urals, which oil to fill

The Lifan engine for the tiller is a universal power unit designed for installation on small agricultural, gardening and construction equipment by the largest Chinese company Lifan, which since 1992 has been specializing in the production of not only equipment, but also motorcycles, cars, buses, scooters. High-performance motors are supplied both to the CIS countries and to the markets of Europe and Asia.

Lifan engines have a wide range of products. All of it is suitable for tillers, cultivators, snow blowers, ATVs and other equipment.

When choosing an engine model, it is necessary to take into account the operating conditions, the brand of the tiller on which the motor will be installed, the volume and types of work performed on the sites, the type of power supply and engine power, the diameter and location of the output shaft.

I put the Lifan engine on the tiller Cascade. It works for a long time, no failures are observed. I installed it myself, bought an installation kit. Affordable price, excellent quality.

Igor Petrovich, 56 years old, Irkutsk region

The Chinese is just super. It consumes little fuel and works efficiently. To my foreman he took a powerful Lifan gasoline engine of 15 liters. from. The power is felt. Works great. Now I am confident in the high quality of Lifan.

Traction class

Light tillers of traction class 0.1 are units up to 5 liters. from. They are purchased for plots up to 20 acres.

Medium tillers with a capacity of up to 9 liters. from. cultivate areas up to 1 hectare, and with heavy tillers 9-17 liters. from. traction class 0.2 treat fields up to 4 hectares.

Lifan 168F and 168F-2 engines are suitable for Celina, Neva, Salyut, Favorit, Agat, Kaskad, Oka vehicles.

The Lifan 177F engine can also be used for installation on medium vehicles.

The most powerful gasoline unit Lifan 2V78F-2 is designed to work in difficult conditions on mini tractors and heavy tillers, such as Foreman, Sadko, Don, Profi, Plowman.

What kind of oil to fill in the engine

The manufacturer recommends using a tiller engine oil that meets GOST 10541-78 or API requirements: SF, SG, SH and SAE. Type of low-viscosity substance. mineral oil 10W30, 15W30.

The manufacturer recommends using AI-92 gasoline as fuel (95).

Ural with ZiD engine

Small batches of tillers were equipped with a ZiD-4.5 power unit. By design, the motor does not differ much from the UMZ-5V. A pulley and sprocket are located on the crankshaft for driving the chain. The pulley is located on the flywheel side, the chain drive on the gear side. The chain drive is used to drive stationary installations. Engine lubrication is performed by splashing, oil is supplied by a plunger pump from a sump that holds 1.5 liters of fluid.

A belt drive is used to transfer torque from the engine to the transmission. The tiller belt has a size of 11201711 mm. The tiller uses a 2-speed transmission, the device and control of which are similar to cars with the UMZ-5V engine. The reducer has 2 speeds, decreasing the rotational speed by 17 and 7 times, respectively. Gear shifting is done with a handle. Before starting the operation of the tiller, it is required to check the level and add gear oil to the gearbox. The rated capacity of the crankcase is 1.5 l.

The engine ignition system includes a magneto that provides a constant ignition timing. With wear, the angle changes, which leads to unstable ignition. To adjust the ignition of the tiller, it is necessary to control the moment when the breaker contacts open and the maximum gap between them. The check is carried out with the flywheel removed by aligning the notch on the crankshaft with the notch on the base of the magneto armature.

The power system includes a K16N or ZiD-12 carburetor and a fuel tank that can hold 8 liters of gasoline. Adjusting the tiller carburetor allows for uniform engine operation and the fuel consumption declared by the factory. Adjustment is made with the engine warm by turning the idle screw and throttle stop screw. Thus, the minimum idle speed is set.

tiller UMB-K “URAL” Engine UMZ-5B Need help?

Hello. Someone’s sleepiness during driving, plowing, cultivation jumped out.

I asked you on another page, WHAT REDUCER, throw a photo

Pavel-M If you give it to a specialist for boring, he will take measurements on the piston himself. But keep in mind that the piston must be under 76 gasoline, or grind the head of the piston by 2-3 mm, I don’t remember exactly, measure it according to the old one. I made repairs 2 years ago, babbitt flowed out due to improper operation (oil starvation due to tilting the tiller forward), the consequences are the kerdyk piston. Found under 93 gasoline, standard, grinded off my head. The gap was large, but did not bore the cylinder, the problem was to find a piston, or rather there was no time. I put on new rings and put them back together. I plowed two seasons without any problems. Engine power with a clearance gap, loam soil, I process in 2 passes (1-3) gears, so as not to force the engine.

Good evening everyone! I ask for advice: on the m / w Ural, the engine breathes and is not weak, there is a desire to change the rings and the piston, strain with spare parts, tell me what they are suitable for (I heard that from a Muscovite) and where you can learn more about assembling and disassembling the engine, how to properly adjust the valve, etc., thanks in advance to everyone!

In my URAL, the cylinder liner was bored out for a new piston. Under the first repair dimension = 82.5 mm. The gap was made = 0.04 mm. Tell me where the arrow on the piston should point during assembly. 1) To the left. in the direction of the flywheel and ignition, or 2) to the right. to the pulleys and the crank. There is a photo of the engine on the forum, but I can’t see it.

Mowers are used to harvest hay for the winter and clear the area from grass. For Ural tillers, there are two options for this attachment: segment and rotary.

Rotary mowers allow you to cut the grass using rotating blades that spin and straighten. This hitch can cut medium-sized young grass.

If it is necessary to process a heavily overgrown area, then it is better to use segment mowers for this. It has two rows of knives that move in turn towards each other. Thus, the segment mowers can cope with coarse vegetation and medium-sized shrubs.

Ural ZID-4.5

This engine does not have any special distinguishing technical characteristics from UMP 5V. The only thing is that it is capable of working on AI-72 fuel, but this affects the operational characteristics of the Ural tiller.

A large amount of carbon deposits begins to form on the cylinders and spark plugs, the stability of revolutions and power in general decreases.

Ural ZID 4.5 was produced as an experimental model, which did not find wide application.

Ural Tiller Review

The first Ural Tillers were released in the early 90s and continue to be produced to this day. Over the entire period of its long history, this technique has found application throughout the territory of the CIS countries, regardless of the type of soil and climatic zone.

The popularity of Ural tillers is due to the simplicity of repair work, a long service life and simplicity of design.

Due to the popularity of this model, the manufacturer has released several modifications of the Ural chillers, which differ in the installed engines.

The most popular are those devices that are equipped with domestic motors. The main reason for this choice is the availability of spare parts and their low cost.

Ural with UMZ-5V engine

The Tiller Ural UMZ-5V engine is a 4-stroke 1-cylinder petrol unit with a volume of 475 cm³. The motor was originally designed for use on self-propelled agricultural machinery and stationary installations. The power unit develops a power of 4.5 liters. from. at 2000 rpm. The plant allows for a short-term increase in power up to 5 liters. from. by increasing the speed.

Long-term operation at increased power is not allowed, as it leads to overheating.

The engine is equipped with an air-cooled system. A fan is used to cool the engine and blows air into a shroud around the cylinder and head. When using the tiller, it is required to regularly inspect and clean the cooling fins from dust and oil. Accumulated dust impairs heat transfer and causes local overheating, which leads to increased engine wear.

The motor is equipped with an automatic speed governor. For this, a centrifugal mechanism is used, which does not allow a rotational speed of more than 2350 rpm. When the speed is exceeded, the throttle valve is displaced, which leads to a drop in the speed. The engine manufacturer prohibits self-adjusting the speed limiter, as well as its use for speed control.

(Part 1) Pitbike Build Tear Down & Swapped Lifan Engine

The gas distribution system consists of 2 bottom valves. Because of this, the motor has a low compression ratio of 6 units. The engine uses automobile gasoline A-76 (A-80) as fuel. The fuel supply is located in a tank located above the engine carburetor, the fluid supply is gravity. The fuel supply in the tank is 6 liters, which provides an operating time of up to 4-4.5 hours. The operating time depends on the condition of the engine and the nature of the tasks performed.

The Tiller Ural engine is equipped with a 2-speed gearbox with crawler gears. The first speed reduces the rotational speed by 6 times and is used to perform work with a high coefficient of resistance (for example, plowing virgin soil). The second speed reduces the revolutions by 2.91 times and is used to operate the product with a trailer or when plowing soft soil. Switching the speeds of the UMB-K Ural tiller according to the instructions is performed with the engine off.

The engine is started by a cord that is wound around the flywheel. Before starting, it is required to set the crankshaft to the end of compression position. Starting the engine is allowed in 1 or 2 gears of the geared motor.

The output shaft of the engine is equipped with a 2-strand pulley designed to transmit torque to the auxiliary gearbox and to drive the attachment. On the fan side, there is a second pulley used to drive attachments that require an increased speed of rotation of the working parts. The clutch mechanism consists of belts and tension rollers.

The transmission crankcase of a tiller with an UMZ-5V engine, according to the repair instructions, is filled with transmission oil in the amount of 1.5 liters. The filling of the substance is carried out through the hole closed with a plastic stopper.

The standard set of attachments for the tiller included a cultivator. For the transportation of goods weighing up to 350 kg, a 2-wheel TOP-350 / 350M trolley was used. When using a single-body plow, an adapter is required to be attached to the frame. The use of the plow is allowed in conjunction with metal wheels equipped with lugs. A mounted potato digger is used in conjunction with the plow.

Correction of major faults and repairs

Each owner of Ural trailers should be familiar with the ways of correcting the main malfunctions that arise during the work on this equipment.
