Lifan engines on a walk-behind tractor: installation, characteristics. Chinese lifan engine for walk-behind tractor

Advantages and disadvantages

Based on the reviews of the model range of the Ural engine blocks, a number of advantages can be distinguished:

• the weight of the product is 120 kg, so there is no need to exert additional physical impact on the handles during work;
• the possibility of change and modernization;
• the motor on the Ural walk-behind tractor with a gearbox has a long resource;
• Effective air cleaner that does not require replacement of filter elements;
• simplicity of design and the possibility of self-repair.

The owners point out the disadvantages:

• Oil leakage at the joints of engine and gearbox parts;
• the need to check the oil level;
• increased fuel consumption and special design of the gas distribution mechanism;
• The tiller is not suitable for long trips with a trailer due to its low speed.

Ural products with ZiD or UMP engines are estimated by owners at 9 to 15 thousand rubles. Motoblocks with Chinese motors are rarely sold, their cost is 14-20 thousand rubles.

Motoblock is used for plowing the backyard. I had problems with ignition at work. After installing the coil from the ignition of a VAZ car, the situation is corrected. Instead of a tape recorder, the battery is drawn from the computer's uninterruptible power supply. The ignition operates steadily throughout the entire rev range. Stop the engine by disconnecting power from the battery.

Dmitry, Kaluga region

The motoblock was bought along with the house and the plot in the village. Maintenance requirements are low, the engine will start after replacing the spark plug, wire and adjusting the ignition switch gaps. When working, it is necessary to compensate for the slight side tilt caused by the heavy flywheel. A92 gasoline is used for operation, since A80 fuel is not produced.

Other common problems when starting the engine

What to do if the motor of the walk-behind tractor works intermittently and does not develop the required power? There may be several reasons for this behavior:

1. Clogged air filter.

Air does not enter the carburetor, which means that the fuel does not burn well - the filter will have to be cleaned or changed.

Fuel residues and combustion products form a thick deposit on the inner walls of the muffler, which must be removed.

1. Carburetor clogged.

In this case, the assembly will have to be removed, disassembled and properly cleaned all of its components. After that, the carburetor must be assembled and properly adjusted.

1. Wear of the cylinder-piston group.

Temperature and high loads do their job, and even the most durable metal wears out and deforms over time. Such parts should be replaced immediately, otherwise you can pay for this with irreparable damage in the engine itself.

1. Damaged ratchet housing or ratchet

The presence of this problem is indicated by the lack of movement of the crankshaft when the engine is started. To replace the clutch housing and ratchet, you will have to completely disassemble the starting block.

1. Loosen the screws securing the starter housing to the engine housing.

If the starter cord does not return to its original position, the starter must be adjusted. For this, the screws are loosened, and the position of the knot is set by hand so as to ensure the normal return of the cord.

1. Starter spring breakage.

A fairly common reason for the lack of return travel of the starter cord is the failure of the starter spring - it will have to be replaced.

The service life of any equipment is significantly increased by competent maintenance of its main units and components.The promptness of replacing worn-out spare parts is also of great importance. Therefore, in the event of the slightest malfunctions and malfunctions, they should be addressed immediately - as a result, this will prevent much more serious and expensive problems.

Change of oil

Oil change operation is an important procedure that affects many driving characteristics and improves the performance of the mechanism.

The frequency of the procedure depends on many factors:

• operating frequency;
• technical condition of the motor;
• conditions of use;
• quality of the oil itself.

Oil change is carried out as follows:

1. Place the motor on a level surface.
2. Unscrew the dipstick and drain plug.
3. Drain the oil.
4. Install the drain plug and close tightly.
5. Fill the crankcase with oil, check the level with a dipstick. If the level is low, top up with material.
6. Install the dipstick, screw tight.

Do not empty the used oil into the ground, but rather take it in a closed container to your local recycling center.

What kind of oil to fill in the engine

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

Decoding of the designations of the Chinese engines Lifan

For clarity, as an example, take the 6.5-horse Lifan 168F-2 engine, which is analogous to the Japanese Honda GX-200 engine. If the Honda number 200 simply means a rounded displacement, then with Lifan it is a little more complicated. In our example, the first digit of the number 168 indicates the number of cylinders, and the next two digits indicate the cylinder diameter in millimeters. Those. 1 cylinder with a diameter of 68 mm.

The letter F means that the engine is in the basic version. The next number 2 is the designation of the engine version. In our case, this is the second version of the Lifan 168F engine (5.5 hp), which differs from it by 1 hp more. power due to the increased piston stroke with the same diameter.

Depending on the version, the name of a particular model of the Lifan engine may contain other designations:

• R - the engine is equipped with a 2-fold reduction chain reducer with an automatic centrifugal clutch. One of the most popular trim levels.
• L - 2 times lowering gear reducer without automatic clutch.
• H - 6 times lowering chain reducer without automatic clutch.
• D - the engine is equipped with an electric starter.
• S - winter version of the engine, which differs from the usual one by the presence of a protective cover, fuel pumping button and other features.
• S Sport is the “sport” version, which is distinguished by increased maximum revs, the presence of connecting rod bearings and other modifications.
• B - engine in a new design: updated gas tank, air filter housing, muffler, etc.
• T - engine with increased power for the same cylinder volume.
• C - "PRO" series, characterized by increased durability of some engine components.
• ECO - a version with improved efficiency and increased gas tank volume.

Output

In my opinion, the most popular are directly the basic models (F-series), slightly less popular are engines with an automatic reduction gear (R-series) and with electric start (D-series). There is little information on the modifications of these engines, moreover, it is often contradictory, so I could be wrong somewhere.

As for the marking of similar Chinese engines from other manufacturers, the same Forza, Brait, Loncin, Zongshen and others, there it is often different.

Preparing a Chinese engine for winter

Lifan engines, what are they?

The Chinese company Lifan has existed for quite a long time, because the company was founded in 1992 and continues to develop until today.At the same time, Lifan is considered one of the main, or to be more precise, one of the leading companies in the Chinese motor market.

The company itself does not only develop engines. Its main direction is the production of cars, motorcycles and other motor equipment. The company has a really huge experience in the development of engines for various equipment.

In Russia, this company became famous for its Chinese engines for motoblocks, because this is a fairly developed type of motor technology that is widely used. If earlier on the product it was written “made in China”, then many Russians rejected it, because the Chinese rule was in force - it means poor quality. Now the opposite is true, with the growth of the Chinese market, the quality of products has increased significantly, while the price of the product still remains very acceptable.

Description

Motoblock Salyut 5 L is reliable, maneuverable, unassuming to the quality of gasoline, easy to maintain, compact, and enjoys well-deserved popularity.

Salute 5 L 6.5 with Lifan engine has exceptional technical characteristics:

• power - 6.5 hp,
• maximum speed - 12 km / h,
• lifting capacity 500 kg.

Engine

The Salute is equipped with the Lifan engine, which is produced by the Chinese company Lifan-Moto and belongs to the group of engines for small motorized vehicles. Thanks to him, the technical characteristics of the Salyut 5 L-6.5 walk-behind tractor are extremely attractive for consumers.

Benefits during operation:

• high quality of engine operation at a reasonable price;
• reduced noise level;
• quick start (TC1 system);
• forced cooling;
• the presence of an automatic blocking of starting at a low oil level;
• the ability to shut off the supply of gasoline to the carburetor using the fuel valve;
• pressure lubrication system;
• unpretentiousness to the quality of fuel - the manufacturer recommends filling in unleaded (leaded) gasoline with an octane rating of more than 85;
• basic service.

Features of running the Lifan engine according to the instructions:

1. Checking the oil level.
2. It is carried out at low or medium load - absolutely not at idle. This is due to the fact that a full check is impossible in idle mode - the lubrication of the internal parts of the piston group of the motor will be insufficient.
3. After 5-8 hours of running-in, the oil is changed to off-season SAE10W30 or SAE 30 (summer).

Transmission

The transmission of the walk-behind tractor consists of a clutch and a gearbox. The clutch in the unit is belt, made on two belts.

Gear reducer

Gear reducer. The toothed connection provides high resistance to various loads, including external impacts from foreign objects. It provides the walk-behind tractor with 2 forward and 1 reverse gears. Gear shifting is carried out using the handle on the gearbox.

Pulley

Changing the speed range, as described in the instructions, is performed by changing the position of the drive belts of the drive pulley to grooves of a different diameter or by reinstalling the power take-off shaft. The recommended brands of oil for the gearbox are TM 5-18 (TAD17I).

Pulley

Through the shaft (pulley) of the power take-off (SHOM), the active drive devices, including various stationary installations and machine tools, are connected to the walk-behind tractor.

Frame

The frame is a standard design in the form of two steel squares with the main components and mechanisms fixed to it.

Cutters

The Salyut 5 set includes four rotary tillers, which cultivate the soil up to 30 cm deep. Processing width - within 60-90 cm. The purchase of two additional cutters is available as an option.

Milling cutter

Pneumatic wheels

Pneumatic wheels are installed on the axle when transporting goods and transporting the walk-behind tractor. In the case of lengthening the axle, wheels with a large diameter are mounted.

Usage Tips

Do not forget to change the oil in Lifan engines. It is recommended to pour high quality and multigrade oil from a bona fide manufacturer. First, drain the old composition, and then fill in the new one. Carry out this procedure on a heated and damp engine.

You can refer to options with such markings:

• SAE 0W;
• 5W;
• 10W;
• 15W;
• 20W;
• 25W.

If there are any problems with the engine, perhaps the following work will save the situation:

• replacement of candles;
• Change of oil;
• checking the integrity of all connections.

Some time after buying a motor for a walk-behind tractor, you will need to carry out one important procedure - to adjust the unit. If this process is neglected, the engine may malfunction or malfunction. Problems with this technique can also arise if the valves are incorrectly adjusted.

According to the rules, this should be done like this:

• first, the valve cover is removed;
• a gap from 0.02 to 0.12 mm is left, therefore it is advisable to take a probe or a high-precision alignment device;
• then the valves are adjusted using a screwdriver and a measurement probe (the latter must fit under the valve);
• unscrew the adjustment screw with a screwdriver;
• after completing all the work, put the covers in place.
