Technical characteristics of the Lifan 168F-2 engine

General description of the Lifan device

LIFAN motor engine with a power of 6.5 liters.With., Depending on the modification, it has a classic layout: it is a single.cylinder carburetor engine with a lower camshaft and a barbell drive (OHV scheme).

Lifan engine

Its cylinder is made by one with a cards of the engine, which, despite the theoretical possibility of replacing a cast.iron sleeve, significantly reduces its maintainability with the wear of the CPG.

The motor has forced air cooling, the performance of which is sufficient when working in hot climate even at high loads.

Ignition system-transistor, during operation does not require any adjustments. A low degree of compression (8.5) of this engine allows it to work on commodity gasoline of the AI-92 brand of any quality.

In this case, the specific fuel consumption in these engines is 395 g/kWh. t.e. per hour of work at the rated power of 4 kW (5.4 liters.With.) at 2500 rpm, with the correct settings of the carburetor, 1.1 liters of fuel will be consumed in an hour.

At the moment, the 168F engines family includes 7 models with various configuration options and connecting dimensions that are the following characteristics:

• Cylinder dimension (diameter/move): 68 × 54 mm;
• Working volume: 196 cm³;
• Maximum output power: 4.8 kW at 3600 rpm;
• Nominal power: 4 kW at 2500 rpm;
• Maximum torque: 1.1 nm at 2500 rpm;
• The volume of the fuel tank: 3.6 l;
• The volume of motor oil in the crankcase: 0.6 liters.

Do.it.yourself motoblock repair

Unfortunately, any technique sometimes fails, so its owner needs to be able to eliminate the malfunctions on his own. Of course, if the car is under warranty, it is better to take it to the service center, where specialists will conduct warranty repairs for free.

Often damage to the cultivator, motoblock occurs due to its incorrect operation: pour poor fuel, allow large loads or do not make up for lubricant losses in time. Then the car begins to stall, “burst out”, it is bad to gain momentum (especially if it has an electric motor), or even stops starting up. But, knowing the device of the unit and the principle of operation of its mechanisms, you can identify the cause of the damage and carry out the repairs efficiently.

Repair of the fuel system

The breakdown of the fuel system can be argued if the engine:

To eliminate the malfunction, first check the condition of all filters, including air and oil. If they are clogged slightly. they make purge with compressed air or flushing; If strong pollution are present on them, they are replaced with new. Then the carburetor is disassembled, the details are washed with a special cleaner, clean the fuel tap tap, tank and a piston system with gasoline. After drying, the reverse installation is carefully performed.

After the motor is completely assembled, the crankshaft is manually scrollful. it is important that the piston goes freely, and the valves work impeccably. Then pour fresh grease, start the motor and leave it to work on the “idle”. Be sure to check the flow of fuel into the cylinder. Perhaps, after such a repair, the cause of the malfunction will be eliminated, and the unoic tractor will begin to function without interruptions.

Repair of the ignition system

You can judge the breakdown of devices for inflammation of the TVS by signs when the engine:

To clarify the reason, first check the condition of the candles and, if there is damage to the insulator, they are replaced. Next, inspect the electrodes and, if necessary, regulate the gap between them. Check the state of high.voltage wires for the oxidation of the tips and insulation disorders. damaged wires must be replaced with new. Without such a repair, a spark can be completely abyss or will leave for isolation, breaking through the engine housing, and will not be able to ensure the ignition of the TVS.

Dismantling and repair of the Lifan168f-2 engine needs help

Which of the oils to use after repair?

The mirror on the cylinder is normal. I think the oil came from the head. Thank you for the photo, it’s always useful to see. In its engines, 10w 40 engotil semi.synthetics, the manufacturer recommends SAE 30, from these I would choose TNK.

LEG wrote: wear or breakdown of oil.removable caps is also relevant

No, it’s not relevant here. There is only one cap here, on the intake. Well, since dismantled, you can change.A penny business.

Good day to everyone! Finally scattered this Chinese dviglo. It was struck that in this motor there is no even primitive oil purification system. The reason for my troubles was an erased oil scrap ring, at first I even thought that it was overlapped (the photo is visible), but as it turned out there was no. The piston is slightly worn, a finger in the bobes and in the sleeve of the connecting rod glides easily. but does not hang out, it pleases!

Bottom line: wash everything, duplicate the rings (preferably Honda), change the oil seals, gaskets, all the same, I decided to use HADO40 oil with an auditalizer later (verified, the effect is there!)

Salute 100 with an engine 168F. Description and price

From many units with a LIFAN engine with a capacity of 6.5 liters.With., The most common is the Salute-100 Tractor Tractor.

The production of this light motor block began in the Soviet Union, according to the then tradition, to load the ELD enterprises with an additional production of the so.called “consumer goods” and continues to this day at the capacities of the NPC gas turbine building salute.

In the configuration with the Lifan 168F engine, such a single.based tractor costs about 30,000. It has a relatively small weight (76 kg), which, in combination with the average for this class, the engine power indicator makes it unprofitable for plowing with a plow without additional weighting.

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

The great advantage of the “Salyut-100” motoblock over a number of classmates is the use of a gear reducer, more reliable than a chain. Gearbox having two front and one rear speed is additionally equipped with a lowering gear.

The “Salute” unoa tractor has no differential, but the narrow track of the wheels (360 mm) in combination with low weight does not make its turn to work.free.

• Sectional mills with protective disks;
• Tigs of expanding ruts;
• Soshnik;
• Rear hitch bracket;
• Instrument set;
• Spare belt.

Additionally, it can be equipped with a plow, a dump, a snowman, metal wheels with developed soil.bearing and other equipment widely compatible with most domestic motoblocks.

The choice of motor oil, which can be poured into the engine of the walk.behind tractor

Motor oil for the “Salute” motoblock with the Lifan engine must only be used in a small (high.temperature viscosity index of not more than 30, in hot conditions. 40).

This is due to the fact that in order to simplify the engine design, it does not have an oil pump, and the lubricant is carried out by spraying the oil with a rotating crankshaft.

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

At the same time, since the low-level of this engine does not make high requirements to the quality of motor oil, you can use the cheapest automobile oils with a viscosity of 0W-30, 5W-30 or with prolonged operation in the heat-5W-40.

As a rule, oils of such viscosity have a synthetic basis, but semi.synthetic and even minerals are found.

At an almost identical price, semi.synthetic oil for air cooling engines is preferable to mineral.

It forms less high.temperature deposits that worsen the heat sink from the combustion chamber and the mobility of the piston rings, which is fraught with an overheating of the engine and power loss.

Also, due to the simplicity of the lubricant system, it is extremely necessary to check the oil level before each launch and maintain it on the upper mark, while replacing the engine oil should be carried out once a year or every 100 motor skills.

On a new or renovated engine, the first oil change occurs after 20 mothers.

How to install Lifan engine on a single tractor?

The Chinese engine is usually put in the case when the native engine has become unusable or its repair is already pointless. The new engine in this case has great advantages over any Soviet. After the purchase, the engine will delight its master for a long time by how it is perfectly tuned. After all, as a rule, any new engine is easy to start and works correctly for many years.

As mentioned above, the engine needs to be selected taking into account the size of the seats, so the complexity of the installation of the Lifan engine on the one.legged tractor depends only on the model of the frame itself, which is supposed to be installed.

The installation itself will be performed in a few simple steps, which even a person can cope with the subject and never engaged in this:

Which engine is better to put on a single.based cascade tractor

Interior combustion engines on the Unoic tractor cascade everything: gasoline, carburetor, single.cylinder, four.stroke, air cooling. The motor starts using an exhaust lace. Work on the device will not cause much noise and involves the permissible level of vibration.

Which engine is suitable for a single tractor?

The motor belongs to the main elements of any mechanism and the effectiveness of the entire device depends on it.

Initially, the engines DM66 and DM68 were installed on the motoblocks. But they often fail due to improper operation, natural wear and other reasons, and therefore it is necessary to replace such a motor if it is not possible to restore it.

Lifan 168

One of the most common engines used to replace is Lifan 168. It has an engine volume of 196 cubic centimeters and works on gasoline. The power is 7 horsepower, cooling air, and therefore they can only work for a short time.

The installation of the motor is simply and will not require the re.equipment of fasteners on the frame.

Fluid replacement work is carried out as follows:

• Unscrew the drain plug on the handle, which is located on the pallet;
• drain the oil from the system;
• Twist the cork;
• pour new oil;
• warm the motor;
• check the level and, if necessary, add.

BS I/C

BS I/C engine can also be installed, which belongs to modern models and is popular in domestic conditions. Often they are used on the units “Cascad”.

This is caused by the following features of the motor:

• power of 7 horsepower;
• enhanced transmission;
• enlarged combustion chamber;
• minimum noise when working;
• high functionality even at low temperatures.

Vanguard OHV

The Vanguard OHV import engine is also related to powerful engines that can be installed on the walkover of this manufacturer and cope with all the necessary tasks. This engine has a power of 7 horsepower.

Subaru EX17

You can also put the Subaru EX17 engine, which is popular among the owners of the CASCADE walk.blocks. He has proven himself perfectly. It has a special design of the distribution mechanism inside and a large diameter of the shaft, which allows you to increase the engine power and its efficiency.

As you can see, there are currently a lot of engines that can be installed on the Cascade motornote. The choice of a suitable model depends not only on its functionality, but also the capabilities of the owner financially.

It is also necessary to pay attention to the package, assembly quality and other points that are familiar to any motorist. If there are no skills, you should always contact specialists for help

The engine must comply with all the requirements, which will allow it to effectively operate and increase the duration of use.

ATTENTION! Use only parts made by the company or similar in quality, otherwise the engine will be broken down. Note: only for two.element carburetors with internal ventilation. For paper filters only. f. When operating in dusty regions, more often than indicated in the schedule. K. If the engine owner is not a qualified specialist or does not have sufficient technical equipment, this should be performed by a dealer.

Warning. Drown out the engine before carrying out any repair. If the repair must be carried out with the engine on, provide good ventilation of the room. Exhaust gases contain toxic oneoxide of carbon, so inhalation it can be dangerous for staff and can even lead to death.

II. Methodology for conducting maintenance.

Oil change. The engine should be hot, but it should be turned off before quickly and completely drain the oil from the crankcase. a) unscrew the lid of the oil crankcase and the cork to completely drain the oil. Set the plug again and tighten it tight.(Rice.22); b) fill the crankcase with recommended oil to the upper mark; c) set the crankcase cover back. Oil volume in 1/2 gear 0.5 l. The volume of oil in the engine. 0.6 l. 160 F, 168 F, 168 F-2; 1.1 l. 173 f.

COMMENT. Do not throw the containers with butter into the garbage boxes and do not drain the oil to the ground so as not to pollute the environment. We advise you to take the spent oil in a closed container to the local processing point.

Air filter maintenance. Polluted air will make it difficult to air flow into the carburetor. To maintain a carburetor in good working condition, regularly carry out the maintenance of the filter. When operating the engine in dusty conditions, clean the filter more often.

WARNING. Never use gasoline or solvent with a low fire point to clean the filter, t.to. This can cause a fire or explosion. WARNING. Never use an air filter engine, t.to. Dirt and dust will fall into the engine and this will lead to its rapid wear.

Two.element type (rice.23). Unscrew the lamb nut and remove the filter lid. Check if the elements are damaged. If defects are detected, replace the part. a) the element: rinse in a heat solution of domestic detergent (or neo.hazardous solvent or solvent with a high ignition point) and let the details dry out. Immerse it in clean machine oil so that the element is saturated. Squeeze the excess oil, otherwise at the stage of the engine starts, it will smoke for a while. b) paper element: several times tap the detail on a solid surface to remove dirt, or blow out of the compressed air of small pressure from the inside. Never use a brush: it will click the dirt in the fibers. If the paper element is overly polluted, replace it.

Cyclone type (rice.24). a) unscrew the lamb nut and remove the filter lid. Check if the elements are damaged. If defects are detected, replace them. b) a foam element: rinse in a warm solution of a household detergent (or a neo.hazardous solvent, or a solvent with a high flame point) and let the details dry out. Immers it into clean machine oil so that it is saturated. Squeeze the excess oil, otherwise at the stage of the engine starts, it will smoke for a while
