Each summer resident who respects himself before the start of the summer season digs up his plot with the help of a walk-behind tractor. But not everyone can afford to buy a new unit. That is why summer residents use cultivators made back in the USSR. All kinds of problems with the engine often arise on such walk-behind tractors, but there are many reasons for this. The main cause of breakdowns is the lifetime, which has long been released. Recently, Lifan engines on a walk-behind tractor have been solving such problems, because this is a profitable way to solve the problem on their own and for a long time.
Lifan engines, what is it?
The Chinese company Lifan has been around for quite some time, because the company was founded in 1992 and continues to develop until today. Moreover, "Lifan" is considered one of the main, and more precisely one of the leading companies in the Chinese motor market.
The company itself is not only developing engines. Its main direction is the production of cars, motorcycles and other motor equipment. The company has truly vast experience in developing engines for various equipment.
In Russia, this company became famous for its Chinese engines for motoblocks, because it is a fairly developed type of motor technology, which is widely used. If earlier on the product it was written “made in China”, then for many Russians it caused rejection, because the Chinese rule acted - it means poor quality. Now, on the contrary, with the growth of the Chinese market, product quality has increased significantly, while the price of the goods still remains very acceptable.
Lifan engine specifications
“Lifanovsky” engines on a walk-behind tractor have various technical characteristics, according to which it is worth choosing a specific engine model for a particular walk-behind tractor model. The first and main feature is the matching installation dimensions. It will be very good if you can choose an engine that is ideal for current mounts. You can choose a model yourself. It is also possible to contact the nearest motor store for the help of professionals. It is important to remember that if the mounts do not match, then you will have to redo them yourself.
The next important characteristic is engine power, which is usually measured in horsepower. The most common universal engines for motoblocks have a capacity of 6.5 horsepower. Such power is usually quite enough for most walk-behind tractors. Engine models are very similar both in installation and maintenance, and in operation.
Engines "Lifan" on a walk-behind tractor should be selected in accordance with the intended tasks that will be assigned to it. If it will be necessary to dig up a small area only once a year, then you should not spend money. It will be quite enough to purchase a simple model from the cheapest price segment, although basically the cost of such engines starts from 9 thousand and all the engines of this company are considered very cheap compared to other brands.
How to install a Lifan engine on a walk -behind tractor?
The Chinese engine is usually installed in the case when the native engine has become unusable or it is already pointless to repair it. The new engine in this case has great advantages over any Soviet one. After the purchase, the engine will delight its owner for a long time with how perfectly tuned it is. After all, as a rule, any new engine starts easily and works correctly for many years.
As mentioned above, the engine must be selected taking into account the size of the seats, so the complexity of installing the Lifan engine on the walk-behind tractor depends only on the model of the frame itself, on which it is supposed to be mounted.
The installation itself will be carried out in a few simple steps, even a person who is far from the subject and has never been involved in such tasks can cope with it:
- Removing the old engine. It is usually made using conventional open-end wrenches or heads. It is simply completely removed by previously disconnecting the gas cables, if present. Also, before removing, throw off the belt that transmits torque to the gearbox.
- Installing a new engine. It is made using the same fasteners, in case they match. If not, then you can redo these mounts yourself by drilling holes or even welding additional metal plates, if necessary.
How to install the Lifan engine on the Cascade motoblock?
The Cascade motor-block itself is interesting to summer residents because it is compact enough and convenient for transportation. Designed mainly for work in summer cottages, small gardens and kitchen gardens. But with all this there is a good opportunity to expand the capabilities of this walk-behind tractor due to attachments.
Installation is quite simple, most often the Lifan 6.5 engine mounts coincide with the factory ones and you just need to replace the engine, start it and start using it. But there are times when the mounts are slightly different. In this case, “getting out of the situation” can be done in different ways.
The easiest way is to make an adapter plate in which you need to make holes for mounting the engine and weld it. If there is no such opportunity, simply screw it into regular places on the frame.
Is the Lifanovsky engine suitable for the Krot motoblock?
A weaker engine with a capacity of 4 horsepower is installed on the Mole, due to the fact that the frame of such an instance simply does not allow the installation of a more powerful engine.
The engine for the Krot motoblock is much cheaper, which for many seems only a plus. For the size of this walk-behind tractor, such power is enough, it copes with the main task - to plow the ground. Of course, it should be used in very small areas where you do not need a lot of power and long work.
Lifan Engine Reviews
Since walk-behind tractors belong to the technique of small-scale mechanization, they are popular in many countries in which people are engaged in agriculture. After all, without motoblocks it is difficult to dig up the earth in its own small area. A tractor is not always convenient and profitable, and manually digging with a shovel is long and difficult, especially if the ground is quite dense.
Engines "Lifan" on motoblocks proved to be really good, because they are not expensive. In addition, they do not require large investments during operation, are unpretentious in maintenance. With all this, the engines have good performance and are reliable.
Their development is basically the achievements of Japanese engineers. Chinese industry rarely develops something new. Most often, they simply take the experience of their brothers, taking a successful instance as a model. It is worth noting that such engines are often used in portable generators, for which the main criterion is precisely the reliability of the installed engine. Some even use motoblocks as a local transport, on which you can transport sand, firewood or something else.
Running in a new engine
Opinions differ greatly on this topic. Some are advised to start and immediately work at half power. Others advise to let idle, warm up the engine. In fact, you need to do exactly as it is written in the instruction manual, because it is not stupid people who make it up, but those who develop the motor and calculate its loads.
It usually takes a long time to break in the engine, but if everything is done in accordance with the manual, then no problems should arise, and if they do, it is important to remember that this is a new motor and this means that it is under warranty. It will be replaced without problems with a new one or at least repaired.
Engine maintenance
During operation, there should not be any significant problems in the case of a fully serviceable new engine, while it is better to check it at maximum power within the warranty period. Engine maintenance is carried out by the owner independently, although there should not be any problems with the Lifan engines on walk-behind blocks.
If you still have problems, you need to perform a number of simple procedures, after which the engine will start working again “like new”:
- Replace candles.
- Change oil.
- Check the integrity of all connections.
No more adjustments are required, since the ignition in such engines is electronic. After performing the above steps, you can try to start the engine.
Motoblock repair
If suddenly it is not possible to start the Lifan engine mounted on a walk-behind tractor, then a simple check is worth it. To do this, you need to perform a series of actions during which it will be possible to determine the cause of the engine malfunction without problems and easily eliminate it:
- Check gas supply. The motor can “catch”, but not start at the same time, because there is a poor intake of gasoline from the tank. The reason may be a clogging of the drainage hole in the cork, which serves to ensure that additional air enters the tank instead of gasoline, which leaves from there. The hose could clog up with garbage or something could get into the tank itself. You need to check all the possible options.
- Check the candle. If suddenly it was smoky or even pierced it, then it is necessary to replace it, because it can not be repaired.
After eliminating these malfunctions, you can try to start the engine. If this does not help, then the cause must be sought in the unit itself.
How to adjust the valves?
After a certain period, it is necessary to adjust the Lifan engine on the walk-behind tractor, because there are failures, that is, it starts to work incorrectly. In fact, there are not so many problems on which the unit may behave incorrectly. One of the main ones is incorrect valve adjustment. It is quite simple to produce it, all work is carried out in several stages:
- The valve cover is removed.
- The gap, as a rule, is by all standards from 0.02 to 0.12 mm, so you need to take some measuring probe or device for accurate exposure.
- Next, the adjustment itself is carried out using a screwdriver and a measuring probe, which should be placed under the valve. The screwdriver in turn unscrews the adjustment screw.
- After setting, you must return the cover to its place.
Change of oil
The oil in the engine of the Lifan motoblock should be filled with high-quality, all-weather, preferably from a good manufacturer. Replacement is quite simple. First you need to drain the old oil. Next, a new one is opened and poured into the motor. It is advisable to carry out the procedure on a warm engine, but it should be drowned out.
The amount of oil, as well as the quality of the necessary oil can be found in the instructions for the motor. It also describes in sufficient detail all the repair and maintenance activities, so that problems should not arise.
