General description of the Lifan device

The engine for the Lifan walk-behind tractor with a power of 6.5 hp, the price of which in various stores ranges from 9 to 21 thousand rubles depending on the modification, has a classic layout: it is a single-cylinder carburetor engine with a lower camshaft and a rod valve drive (OHV diagram ).

Its cylinder is made in one piece with the engine crankcase, which, despite the theoretical possibility of replacing the cast iron liner, significantly reduces its maintainability when the CPG wears out.

The motor has forced air cooling, the performance of which is sufficient when operating in hot climates, even under heavy loads.

The ignition system is transistorized and does not require any adjustments during operation. The low compression ratio (8.5) of this engine allows it to run on commercial AI-92 gasoline of any quality.

Moreover, the specific fuel consumption of these engines is 395 g/kWh – i.e. for an hour of operation at a rated power of 4 kW (5.4 hp) at 2500 rpm, with the correct carburetor settings, they will consume 1.1 liters of fuel per hour of operation.

Currently, the 168F engine family includes 7 models with different configuration options and connection sizes, which have the following characteristics in common:

Cylinder dimension (diameter/stroke): 68×54 mm;
Working volume: 196 cm³;
Maximum power output: 4.8 kW at 3600 rpm;
Rated power: 4 kW at 2500 rpm;
Maximum torque: 1.1 N*m at 2500 rpm;
Fuel tank volume: 3.6 l;
Engine oil volume in the crankcase: 0.6 l.

Modifications

Lifan 168F-2

The cheapest configuration with a connecting shaft size of 19 or 20 mm. The manufacturer's price is 9,100 rubles.

For more details about the operation of the Lifan 168F-2 engine, watch the video:

Lifan 168F-2 7A

Motor variant equipped with a lighting coil capable of powering consumers up to 90 W. This allows it to be used on a variety of equipment that require lighting devices: motorized towing vehicles, light swamp vehicles, and so on. Price – 11,600 rubles. The shaft landing diameter is 20 mm.

Lifan 168F-2 ignition circuit

The power unit has a conical shaft output; it differs from the base model only in the conical groove of the crankshaft toe, which ensures a more accurate and tight fit of the pulleys. Price – 9500 rubles.

Lifan 168F-2L

This engine has a built-in reduction gearbox with a landing diameter of the output shaft of 22 mm and costs 12,100 rubles.

Motor Lifan168F-2R

The motor is also equipped with a reduction gear, but with an automatic centrifugal clutch, and the landing size of the secondary shaft of the gearbox is 20 mm. Engine cost: 14,900 rubles.

Lifan 168F-2R 7A

As is clear from the markings, this version of the engine, in addition to a reduction gearbox with an automatic clutch mechanism, has a seven-amp light coil, which increases its price to 16,500 rubles.

Lifan 168FD-2R 7A

The most expensive version of the engine, priced at 21,500 rubles, is distinguished not only by the diameter of the gearbox output shaft increased to 22 mm, but also by the presence of an electric starter. However, the rectifier required to charge the battery is not included in the delivery package.

Clutch repair

The clutch on the Zubr walk-behind tractor does not work - unfortunately, many owners of this equipment have encountered this problem. Usually it looks like when you squeeze it out, the car stops for a couple of seconds, and then continues moving as if nothing had happened.

The main reason for this problem is contamination of this part. In order to solve it, in most cases it is enough to remove the clutch and wash it thoroughly. After installing it back, everything should work again.

Repair and adjustment, speed adjustment

Engine repair sooner or later awaits any walk-behind tractor, be it Cayman, Patriot, Texas, Foreman, Viking, Forza or any other. The procedure for disassembling and troubleshooting is simple and does not require any special tools.

It should be noted that the manufacturer does not indicate specific wear limits for troubleshooting any engine components, therefore the dimensions given below are indicated by analogy with other four-stroke air-cooled engines:

Drain the oil from the crankcase and gearbox (if installed), removing the drain plugs, and the remaining fuel from the gas tank.
Remove the fuel tank, muffler and air filter.
Disconnect the carburetor attached to the cylinder head with two studs.
Remove the recoil starter mechanism and fan shroud.
Having secured the flywheel with a handy tool so as not to damage the fan blades, unscrew the nut securing it.
After this, use a three-legged universal puller to press the flywheel off the seat cone.
If the reason for disassembly is poor starting and reduced engine power, check whether the keyway is broken, as in this case the flywheel will move and the ignition timing, determined by the magnetic mark on it, will change.
Remove the ignition coil and lighting coil, if the engine has one.
After unscrewing the valve cover bolts, unscrew the four cylinder head bolts located under this cover and remove the head. To check the tightness of the valves, turn the head of the combustion chamber up and fill it with kerosene.
If kerosene does not appear in the inlet or outlet channel of the head within a minute, the tightness of the valves can be considered satisfactory, otherwise they need to be rubbed into the seats with abrasive paste or (if burnout is detected) replaced.
On models equipped with a gearbox, remove the gearbox cover and the output shaft, then press the drive gear or sprocket (depending on the type of gearbox) off the crankshaft. Replace gears with noticeable tooth wear.
Unscrew the bolts holding the rear cover around the perimeter and remove it, after which you can remove the camshaft from the crankcase.
Having thus freed up space in the crankcase, unscrew the bolts connecting the bottom cover of the connecting rod to its body, remove the cover and crankshaft.
Push the piston along with the connecting rod into the crankcase.

If play is detected in the bearings, replace them. Also, since repair dimensions of parts are not provided, they are replaced with new ones:

Connecting rod: with increased radial play on the crankshaft journal to a noticeable extent;
Crankshaft: when scoring on the connecting rod journal;
Carter: with significant (more than 0.1 mm) wear of the cylinder mirror in the greatest place;
Piston: in case of mechanical damage (chips, scuffing due to overheating);
Piston rings: when the gap at the joint increases above 0.2 mm, if the cylinder mirror itself does not have wear that reaches the rejection limit, as well as when there is noticeable waste of engine oil.

Carrying out diagnostics of a walk-behind tractor

Before directly repairing walk-behind tractors, you will have to diagnose the entire system. Thanks to a routine inspection of equipment, it is possible to determine the failure factor. If the spark plugs are the cause of the problem, then they are removed and cleaned of fuel. Then the injectors are thoroughly dried to normalize the supply of gasoline.

Another circumstance is the presence of carbon deposits on the candles. To eliminate this problem, the parts are cleaned using fine-grained abrasive paper, and then the gap between the electrodes is checked. The normal distance is 0.7-1 mm.

If there is no spark, then the spark plugs need to be replaced. Old elements are first checked for functionality. To do this, the parts are connected to the battery using an auxiliary wire.

Salyut 100 with 168F engine - description and price

Of the many units with a 6.5 hp Lifan engine, the most common is the Salyut-100 walk-behind tractor.

The production of this light walk-behind tractor began in the Soviet Union according to the then tradition of loading military-industrial complex enterprises with additional production of so-called “consumer goods” and continues to this day at the facilities of the Moscow JSC NPC Gas Turbine Construction Salyut.

When equipped with a Lifan 168F engine, such a walk-behind tractor costs about 30,000 rubles. It has a relatively low weight (76 kg), which, combined with the average engine power for this class of equipment, makes it unsuitable for plowing without additional weight.

But for cultivation it is quite good due to the included sectional cutters, which allow you to change the working width from 300 to 800 mm depending on the severity of the soil.

The big advantage of the Salyut-100 walk-behind tractor over a number of its classmates is the use of a gear reducer, which is more reliable than a chain reducer. The gearbox, which has two forward and one reverse speeds, is additionally equipped with a reduction gear.

The Salyut walk-behind tractor does not have a differential, but the narrow wheel track (360 mm) combined with its low weight does not make turning it labor-intensive.

Sectional cutters with protective discs;
Tread expander bushings;
opener;
Rear linkage bracket;
Tool set;
Spare belt.

Additionally, it can be equipped with a plow, blade, snow blower, metal wheels with developed lugs and other equipment that is widely compatible with most domestic walk-behind tractors.

Failure detection

Fixing walk-behind tractor breakdowns with your own hands always begins with their correct identification. If you notice any problems in the operation of your two-wheeled assistant, but cannot independently determine their cause, call 2-3 neighboring owners of two-wheeled assistants for help. Typically, such a “consultation” identifies a possible malfunction with almost 100% accuracy; in addition, more “technically savvy” neighbors are always ready to delve into someone else’s mechanism, actively helping to eliminate the breakdown.

When starting troubleshooting, you need to carefully read the operating instructions for your model in order to have a clear understanding of its structure. Most often, owners have to repair the engine of a walk-behind tractor, since the engine is the most complex in design, and therefore the most problematic unit in any mechanism. Also, owners often have to repair the gearbox on a walk-behind tractor themselves.

Selecting motor oil that can be poured into a walk-behind tractor engine

Motor oil for the Salyut walk-behind tractor with a Lifan engine must be used only with low viscosity (high-temperature viscosity index no more than 30, in hot conditions - 40).
This is due to the fact that, in order to simplify the design of the engine, it does not have an oil pump, and lubrication is carried out by splashing oil from the rotating crankshaft.

Viscous engine oil will lead to deterioration of lubrication and increased wear of the engine, especially its most loaded sliding friction pair in the lower connecting rod head.

At the same time, since the low level of boost of this engine does not impose high demands on the quality of motor oil, you can use the cheapest automobile oils with a viscosity of 0W-30, 5W-30, or for long-term operation in the heat - 5W-40.

As a rule, oils of this viscosity have a synthetic base, but semi-synthetic and even mineral ones are also found.

At almost the same price, semi-synthetic oil for air-cooled engines is preferable to mineral oil.

It forms fewer high-temperature deposits, which impair heat removal from the combustion chamber and the mobility of the piston rings, which can lead to engine overheating and loss of power.

Also, due to the simplicity of the lubrication system, it is extremely necessary to check the oil level before each start and maintain it at the upper mark; the engine oil should be changed once a year or every 100 hours of engine operation.

On a new or refurbished engine, the first oil change occurs after 20 operating hours.

Motoblock maintenance. Changing the oil in the engine and gearbox. Preparation for spring field work.

Spring is just around the corner! The snow will quickly melt, streams will flow, opening up fields and vegetable gardens before us - springboards of labor and creativity! Busy time for every summer resident and gardener. It is important to enter the season fully armed.

We will talk about servicing a lightweight Agat walk-behind tractor with an air-cooled 4-stroke HAMMERMANN 6.5 HP engine.

Timely replacement of oil in the engine and gearbox is a necessary procedure for a walk-behind tractor. Treat this responsibly. The durability and quality of operation of units directly depends on the quality and types of oils used. Any competent salesperson in car oil stores will give you good advice - the main thing is to define the task - after all, this is not a car, but garden equipment. Please note that the mechanisms are subject to heavy loads and high temperatures (in the absence of cooling). Filling a walk-behind tractor with expensive synthetic oil, just like in your car, will simply throw money away. The additives will burn out, leaving carbon deposits on the internal components. Consider this point - the choice is yours))) You can use motor oil for 4-stroke engines of the SAE 10W-30 or SAE 15W-40 class.

First, let's look at the filler plugs - in our case there are two of them plus a drain bolt in the front lower part of the engine. The instructions included with the walk-behind tractor do not provide precise explanations. Without complicating the situation, drain the old oil by unscrewing the plug that has easy access to it. The front part of the walk-behind tractor is orange. (access to the drain bolt is difficult due to the additionally installed second trailer bracket) We drain the oil into the prepared container by tilting the walk-behind tractor - simply lift it by the steering wheel.

Knocking in the box

The gearbox is one of the main elements of a walk-behind tractor. It is with its help that speeds are switched, which in different models can be from three to six. The most common problem with it is extraneous noise and knocking.

The following reasons are often responsible for extraneous noise:

wear of gear shift parts;
wear of gear ends;
bearing wear.

Among all the parts responsible for switching speeds, shafts, especially their bends and splines, are subject to the greatest wear. The only way to fix the problem is by replacing them. As for the gear teeth, they are corrected by grinding. Otherwise, in addition to noise, incomplete speed switching will be observed.

Important! As for bearings and retaining rings, they are simply replaced due to wear.

Monitor the integrity of the circuits in your walk-behind tractor

How does the engine for the Salyut walk-behind tractor work?

Auto mechanic, specializes in agricultural equipment

Today, there are a large number of different models of special equipment that are used for soil cultivation in agriculture. Here devices of the salute model are often distinguished. This equipment is in great demand among agronomists, but a distinctive feature of walk-behind tractors is the short service life of their engine.

Due to the fact that the build quality is not the best, it is necessary to select models that are equipped with an improved power plant from a more famous manufacturer. In this case, you need to familiarize yourself with the Briggs Stratton engine, and also find out which models can replace it, and how to change the oil in the engine of a salute brand walk-behind tractor.

Before purchasing this walk-behind tractor, you need to decide on the model.

Types of malfunctions of walk-behind tractors

Sometimes the walk-behind tractor begins to act up due to some problems. However, you can easily fix them yourself without turning to specialists for help. To do this, you will need to carefully study the technical parameters of the system, after which you can begin repairs.

The main malfunctions of the device are:

engine operation with minor interruptions;
failures due to which the unit stops working completely, etc.

If such violations occur, repair work is carried out immediately.

Engines for the Salyut walk-behind tractor

Before considering in detail the procedure for changing the oil for the Salyut 5 walk-behind tractor, you need to familiarize yourself with the models of power plants that are mounted on these devices. Let's take a closer look at all the currently used options:

Briggs Stratton (an excellent power design, but in some cases it is characterized by a lack of power). In some individual cases, power units may act up due to lack of oil.
Honda (all owners of walk-behind tractors with Honda engines are satisfied with the power capabilities of the installation, with such an engine the device feels confident on any arable land).
The Salyut 100 walk-behind tractor is often equipped with engines from the manufacturer Subaru (the selection of a Subaru engine, like a Honda engine, must be carried out taking into account a comparison of all characteristics).
Devices from the manufacturer Lifan are distinguished by their lower cost (special equipment with a Lifan engine has a long service life, but here you need to pay attention to the spark plugs - they are periodically filled).
Asme equipment (another manufacturer that actively provides high-quality EX 27 motors for domestic walk-behind tractors of the Salyut brand; the engines have good characteristics, their feature is their low price).

Among such a number of power plants, it is quite difficult to choose the most suitable option for yourself. That is why all units must be considered in detail and in full.

In this video you will learn about the engines in salute walk-behind tractors:

Important! When choosing a unit for your special equipment, you need to take into account the operating features, since any of the motors has more positive qualities in any direction.

Briggs Stratton

Quite often, engines of this brand are installed for the Salyut walk-behind tractor. Let's look at the main distinguishing features of these power plants:

the most common are gasoline engines that are unpretentious to Russian fuel;
here the pulley for the Salyut brand walk-behind tractor is made of durable material, which increases the service life of the installation;
These devices are also characterized by high power, which allows you to freely process the soil;
The Stratton walk-behind tractor Salyut 5 is usually equipped with this particular engine, which is why the model is very popular.

Also, these devices are characterized by low oil consumption, and also low cost. At the same time, large investments in repairs and maintenance during operation are not required.

Important! If a power unit from this manufacturer is installed, it is recommended to regularly check the oil level, since if it is insufficient, the engine may have a shorter service life.

Honda

These power structures are widespread throughout Russia. Let's look at the main distinguishing features of these devices:

high power;
ability to work for a long time at high speeds;
improved maneuverability;
high torque;
unpretentiousness to Russian fuel;
reliable assembly and long service life.

All these qualities distinguish engines from the manufacturer Honda. However, despite the quality, the cost of the units is quite high when compared with other similar options for units for Salyut walk-behind tractors.

Important! The engine is characterized by high speeds, which makes it quite voracious in comparison with other manufacturers of units for similar special equipment.

This engine needs a lot of fuel

Subaru

Another power plant that is very popular among owners of special equipment. These models have absorbed all the positive qualities from other manufacturers. Due to the many models released, it is recommended to first compare all the characteristics, since after installing the Subaru engine, the walk-behind tractor may change significantly. Here it should be understood that the devices have a fairly high cost, but the service life is also higher. Additionally, it should be noted that both gasoline and diesel can be used as fuel here. This point should be taken into account when purchasing.

Important! Subaru engine units have high power and are operated at high speeds, which is why high fuel and oil consumption may be periodically observed in comparison with other power plants.

Lifan

These motors for walk-behind tractors appeared relatively recently, but are already very popular among gardeners and commercial organizations involved in agriculture. Let's consider the main characteristic features of these motors:

products are available in various capacities;
there are both diesel and gasoline units here;
motors have a long service life;
moderate power and operating speed;
fairly low cost of the devices;
the versatility of these devices;
improved thrust of Lifan engines;
compact dimensions (motors are easy to install).

Also, these installations are not highly voracious during frequent use (the engines do not consume large amounts of fuel or oil, compared to other similar models from other manufacturers).

The starter squeals, the cord comes out

— It may squeal if there is a lot of grease on the balls. You need to clean the balls and the places in the ratchet where they are inserted.

The cultivator made several pops, the speed began to “float”

— Most likely, the power system is not coping, or the fuel level in the tank is low, the float axis may be skewed and debris may have gotten under the needle valve, you need to remove everything and check the air filter and jets.

The material will be updated, we are waiting for comments with questions, stories about identifying a particular malfunction and ways to eliminate it. Also, see the answers to questions about a particular walk-behind tractor model on its description page.

Engine oil

An internal combustion engine is a complex mechanism consisting of a large number of elements. To ensure reliable and long-term operation of all components of the device, it is necessary to select and fill the engine oil correctly. Here a natural question arises: what oil to use? Before answering this question, it is necessary to clarify what qualities such a composition should have:

Have sufficient viscosity so that the components can be held on all elements of the motor.
Be resistant to temperature changes (since in operating condition and when the ignition is turned off, this parameter can differ significantly).
Do not lose viscosity when the engine heats up to high temperatures (with accelerated operation of internal elements).
Maintain viscosity for a sufficient time to extend the life of the power plant.
Contain active additives that reduce the load on engine components during friction.

All these characteristic features must be present in the oil used for the walk-behind tractor. Choosing a quality product will extend the life of the motor, and, in addition, you will not often need to spend money on maintenance. As a rule, special equipment is used for special equipment, which has a high viscosity. Currently, you should give preference to synthetics, as they have the longest service life.

Important! During the operation of the walk-behind tractor, it is necessary to regularly maintain the oil level in the engine at the optimal value; if this point is not monitored, then there is a high probability that the engine structure will sooner or later fail.

Replacing a motor unit or oil, as well as choosing the right components, is a task that not everyone can handle. If any difficulties arise, you should not try to complete the work by mistake. It is recommended to entrust these moments to specialists. Our company’s employees are ready to take on all these issues. You just have to wait for the result, which will not keep you waiting.

For our efforts, our organization will only ask for a modest reward. At the same time, the satisfied client will also be provided with a long-term guarantee for all types of services that were provided. Based on this, we can conclude that you should not try to understand a complex technological process on your own if you do not have the appropriate knowledge and skills; it is much easier to entrust everything to professionals, and while they are working, enjoy your vacation.

Repair of Zubr walk-behind tractor

Repairing a Zubr walk-behind tractor with your own hands is not such a difficult procedure if you have a good understanding of the mechanism itself. Therefore, the first step is to decide what type of device we are talking about:

about a light walk-behind tractor;
average;
heavy.

You can repair a walk-behind tractor with your own hands.
The main distinguishing features of light machines are their low power, low weight and small size. Low power means one that does not exceed six horsepower. They are used for cultivating summer cottages and gardens with a small area and soil that has been cultivated more than once.

Medium-sized ones include walk-behind tractors with engines with a power of up to eight horsepower. Their weight is also larger and can reach 120 kilograms. At the same time, due to their greater power, they are often equipped with diesel engines. They are used for small farm plots of up to a hectare and large vegetable gardens.

Heavy walk-behind tractors are designed for cultivating real fields. This requires them to have decent power, which is 15 horsepower for most models, as well as an economical approach to fuel consumption. Because of the last factor, they are most often made diesel. They also weigh a lot - up to several tons.

In this video we will look at the repair of the Zubr walk-behind tractor:

Knowing the differences between the three types of walk-behind tractors is necessary in order to select the right components. For the same purpose, it is necessary to correctly identify the breakdown. Find out what specific part is broken. Most often problems arise:

in the engine;
clutch;
fuel pump;
valves;
radiator

Common signs that unpleasant processes are occurring include the appearance of strange-colored smoke from the exhaust pipe, unexpected knocking noises inside the car, and lack of power. It is worth noting that not every alarming sound is a sign of a serious problem.

Thus, knocking and vibration often appear due to screws that are not screwed tightly enough. And at the factory. Smoke may be related to the quality of the fuel, and insufficient power may be related to the terrain.

But even if the owner of the Bison encounters troubles, he can be sure that he will be able to overcome them - after all, it is quite easy to buy components for it and they are not expensive.

Important! Before you begin self-repair, you will also have to ensure that you have special tools. These are keys, screws and screwdrivers.

Engine for Salyut walk-behind tractor - do-it-yourself oil change

Proper maintenance and operation of the Salyut walk-behind tractor helps to extend the service life and improve the performance of the equipment. The gearbox and engine of a walk-behind tractor are one of the most important structural elements. What kind of oil should be poured into the gearbox and engine of a walk-behind tractor, as well as the frequency of its replacement, the volume is data that every owner of such equipment needs to know.

The most reliable recommendations will be those offered by motorcycle manufacturers. Let's turn to the user manuals for the Salyut-5 and Salyut -100 walk-behind tractors.

Oil for the gearbox of the Salute walk-behind tractor

Fill the walk-behind tractor gearbox with oil through the oil filler hole of the gearbox.
The gearbox should be filled with 1.1 liters of TM-5-18 (TAD-17I) oil; check the level with a dipstick. To prevent oil from spilling out of the gearbox, engine crankcase and fuel from the engine fuel tank, the walk-behind tractor should be installed on the vehicle in its normal operating position during transportation.

ATTENTION! Before each start of work, check the oil level in the engine, as indicated in the “Engine Operation Manual”. Pay special attention to the safety precautions when starting the engine as specified in the Engine Operator's Manual. Work on a walk-behind tractor with a closed or half-open air damper is not allowed.

Excerpts from the user manual:

Maintenance performed after the first 25 hours of operation:

— Check the tightness of the threaded connections of the gearbox and walk-behind tractor components;

— Check the oil level in the walk-behind tractor gearbox

Work to be performed after every 100 hours of operation:

— Change the oil in the walk-behind tractor gearbox;

Checking and filling oil into the gearbox of the Salute walk-behind tractor

ATTENTION! Work on replacing and measuring the oil level in the walk-behind tractor gearbox should only be carried out with the engine not running!

Fill oil into the gearbox of the walk-behind tractor through the oil filler hole of the gearbox. Check the oil level in the walk-behind tractor gearbox as follows:

— to measure the oil level in the gearbox, the walk-behind tractor must be installed in a horizontal position;

— move the gear shift lever to the “Reverse” (R) position, then unscrew the plug on the oil filler hole of the gearbox and insert the dipstick into the oil filler hole until the horizontal part of the dipstick handle rests against the edge of the hole;

— remove the dipstick from the oil filler hole and assess the oil level. The oil level in the gearbox must be between two marks: if the oil level is below the lower mark, then the oil must be added;

— the lower line shows the oil level

0.85 l (180 mm from the edge of the oil filler hole), and the top line

1.1 l (125 mm from the edge of the oil filler hole);

— after use, wipe the dipstick with a rag and put it in the tools;

— tighten the oil filler plug of the gearbox;

— drain the used oil from the gearbox through drain plug 6 (Fig. 6).
