Tire of the chainsaw: how to measure, choose, install and fix
Control of the movement of the circuit with fixing its tension and regular lubrication is provided by one simple and absolutely indispensable element. The saw tire belongs to the category of consumables, since it takes on peak loads that deform and seriously wear it out as it is working. This article will briefly and clearly show what criteria to select a new part, how to install on the tool and make easy repairs.
The general idea of the structure of any element consists of knowledge of its components and an understanding of their interaction. To operate the tire as long and efficiently, it is useful to have a clear picture of the principle of its action. The functional role of the detail in the chainsaw system is extremely clear to everyone who observed this tool in work. First of all, the tire serves as a guide for the chain, as well as a means of its tension and lubrication.
With a cursory examination of the element, it seems that it is cut out of a solid sheet of metal. In fact, the tire consists of 3 plates (2 side and one central), reliably fastened with rivets. The central element is an order of magnitude shorter and thinner than the lateral, due to the formation of guide grooves in which the shanks of the chain are immersed. The free space in the front (on the nose) of the tire is occupied by a led by a stars, which ensures the free stroke of the chain during tension.
To facilitate movement and protection against erasure, the asterisk is installed on the bearing, the central part of which is attached to the side plates. For the maintenance of a mechanism expressed in cleaning and lubrication of rollers, special holes are provided on both sides of the tire.
In the tail of the guide, there are a number of technological holes. The largest, elongated opening, provides an even installation of the canvas along two studs fixed on the engine crankcase. In one of the 2x symmetrically located holes, the finger tensioner is inserted, and the oil pump fitter includes the smallest that supplies the lubricant on the shank of the chain when working.
How to determine the length of the chainsaw tire?
The cutting part is far from the entire length of the saw canvas. The distance is measured from the front of the tool body to the rounded tip of the chain installed on the tire. The resulting value is rounded to centimeters or inches, it is 2.54 cm. Then calculate according to the given table, which size is suitable for a specific tool.
If, going to the store, you doubt your abilities to determine the size of the chainsaw tire, take the tool with you or provide the consultant with a passport for the product, which usually indicates the main parameters.
If the saw saws crookedly. Reasons and what to do
Often, sawmiths are faced with the fact that at one moment the saw begins to saw crooked. This causes not only inconvenience, but also complicates the treatment procedure. The sawmill has to make efforts not only to keep the tool, but also to equalize it. Few people know that it is prohibited to operate a tool with such deformation. We will find out what is the cause of the uneven sawing of the chainsaw, and what is dangerous for the sawmill.
If the saw begins to cut crookedly, then this indicates the presence of an inconspicuous deformation of the tire. The deformation is associated with the side of the tire, which has uneven wear. As a result, the chain is located not evenly, but with a slight skew. The skewing value can be invisible to the eye.
Eliminate the malfunction in the form of uneven wear of the tire can be replaced. It is almost impossible to carry out uniformly grinding sides of the guide, so it is recommended to replace it with the chain. The danger of the exploitation of a deformed guide chainsaw is that the tail of the chain can jump out of the groove, which will entail not the most prosperous consequences.
The tire of the chainsaw, like the chain, experiences heavy loads, so its wear is observed
With wear, it is important to replace the part in a timely manner without waiting for adverse consequences. How to choose, and what to consider when buying a tire on a chainsaw, is described in detail in the material
The size of the chain
This parameter always depends on the size of the tire installed on the unit. If you accidentally purchased a smaller chain than your tire, it will not work to wear it. If this element has a size exceeding the size of the tire, you cannot pull it. Both options do not allow the use of inappropriate chain sizes. They are usually indicated in inches and have the following values: 10 ″, 12 ″, 13 ″, 14 ″, 15 ″, 16 ″, 18 ″ and above.
The length of the chain is determined by the number of links. The links mean connecting links that enter the groove tires, and not cutting teeth. When buying, you can indicate the seller either the length of the part in the inchs, or the number of links that make it up. Some manufacturers instead of length indicate the number of links in the saw element. As a rule, this number does not depend on the thickness of the tail, step and height of the profile. For example, a low.Profile chain with a 1.3 mm leader thickness can consist of both 72 links and 56 links or their other number.
How to measure the length of the chainsaw tire
If a few decades ago, a chainsaw for many was considered unrealistic luxury, today it has become an indispensable assistant in the household. Indeed, now such a saw is an integral attribute in the household, in a private house, in the country or for those who are engaged in a sawing or roll of trees, as well as construction work.
Fortunately, the for unprofessional and professional chainsaws are quite acceptable today, which allows you to purchase them almost everyone. However, one should not forget that any equipment during operation needs prevention, and sometimes also to replace the nodes and spare parts.
There are frequent cases when a tire for a chainsaw requires a replacement, which is quite simple, for example, in the Helphouse Internet Market Mark. However, many are afraid that they do not know how to choose a tire for a chainsaw, because their size is so diverse that it is easy to get confused.
Useful tips on how to measure the length of the chainsaw tire:
- It is necessary to measure the distance from the end of the chain saw to the place in which the tire enters the case and round the resulting value to the nearest even number.
- Calculate the total number of drive links in the chain.
- Make measurements to determine the height of the chain.
If you cannot figure out how to measure the length of the tire of the chainsaw, it is better to seek advice to professionals.
The thinner the tail, the less they are designed for electric saw. One of the most popular products has a thickness of 1.3 to 1.6 mm. Products of 1.3 mm thick are designed for household tools, and above. For professional.
The length of the chain
The length of the device depends on the tool itself. For each tool, the length of the chain can be found directly in the operating instructions. This figure largely depends on the length of the tire, as well as on the power of the tool and the size of the stars.
The length affects such a parameter as the number of links. In turn, the number of links depends on their height. Choosing a chain for a chainsaw, you should know the length and step of the links. The longer the design, the more power should have a chainsaw.
The depth of cutting
The performance of the chainsaw is affected by factors such as the depth of cutting or cutting. This criterion depends on the parameters of the cutting tool or, in other words, on the height of the tooth profile. The larger the size of the tooth, the greater the depth of cutting for one circuit pass. This affects the speed of sawing, which is directly proportional to the height of the tooth.
It is important to know! The higher the height of the teeth, the less durable the product. In addition, the larger this parameter, the more efforts are required for cutting wood.
In networks of different manufacturers, this parameter is installed without observing any standards. Standard chainsaws have two types of dental profiles high: 0.635 and 0.762 mm. The first option is called low, and the second. High.
Type of link
- The chubby machine in shape resembles a sickle and is characterized by high performance characteristics. This type of links is easy to sharpen, but its main disadvantage is the deterioration of cutting parameters.
- The chisels have a working tooth in the form of the number of “seven”, and they are used mainly in the form of chains, the step of which is 0.404 inches or 0.325 inches. They have high sensitivity to dirt and have a shortage of more sharp sharpening.
- The carbide is tilted
The sequence of links is diverse. There are the following main types of sequences:
- Standard. All links are cut and connected by wires (this is standard).
- Halfway. Cutting links alternately with one link, then with two.
- With a pass in this case, the cutting links are separated from each other by two connectors.
To ensure good cuts, the standard type of links of links is used. The smaller the links, the lower the performance of the chain and the faster it wear out.
Type of sawing
Preferably chainsaws are used to saw wood in cross section. In rare cases, it may be necessary to use a tool to perform a longitudinal saw. Depending on the type of saw, it is advisable to use the cutting tool of the corresponding form. The type of saw chains are divided into longitudinal and transverse.
This parameter is affected by the angle of sharpening of the cutting link. For the longitudinal sawing, the angle of sharpening should be larger than for the transverse, and preferably 5-15 degrees. For the cross section, the angle is 25-35 degrees. These values are usually indicated on the surface of the cutting links.
In most cases, the cutting tooth is made directly from highly alloyed chromium.Nickel steel. Teeth are not subjected to heat treatment, as they are designed for sharpening. When processing very hard or frozen wood materials, it is advisable to carry out tooth hardening or purchase products with a special soldering on the teeth.
How to buy a new network
To choose the right chain for your chainsaw, you must take into account all of the above criteria, as well as pay attention to the manufacturer and the cost of the product. A good product will never have a low cost, which may indicate the manufacture of nozzle from low.Quality materials.
You can watch a video on how to choose the right chainsaw:
The video shows the most popular chainsaws. Chains are consumables. Therefore, it is best to experiment with personal experience to determine the most effective product for yourself.
It is important to emphasize the importance of knowledge of what type of tool your chainsaw belongs to. If this is a home file, do not attach investments for professional tools to it.
How to determine the length of the tire for the chainsaw
Chainsaw is one of the most necessary and available to any radial host tool: neither a summer house nor the owner of a private house will do without it. Drive harvesting, pruning trees and shrubs, construction or repair of arbors, benches, verandas, etc.D The first assistant in such household chores is always a chainsaw. Professional masters at serious construction sites and forestry will not be without it.
Classification of saw tires
The sawtime set is called the operating elements of the chainsaw, which are designed to directly perform the sawing: chain and tire.
One of the moments affecting the choice of a particular model is the type of tire and its length. Feet tires for chainsaws are classified as follows:
- Narrow flat. Works in pairs with a low.Profile chain of unprofessional household level chainships, minimizes the danger of injuries due to the practical lack of the effect of a “reverse blow”, which is especially important for newcomers of benches;
- Lightweight. Made of two steel, connected by a polyamide layer of plates. Such constructive execution significantly reduces the total weight of the chainsaw itself, which can serve as a serious advantage when performing some kind of work;
- A tire with a replaced head. Installed on professional chainsaws of medium and high power used for a large volume of long.Term work.
Tire type is a serious characteristic, but not the only one that must be taken into account when buying a chainsaw.
Tire length. We pay attention!
That which is not least throws into the eyes when choosing a chainsaw is the size of the tires: it depends on them how large the log of the log can be cut.
The length of the chainsaw tire is one of the most important parameters affecting convenience, speed and safety of work. This characteristic should be agreed with the operating power of the chainsaw engine, which is why any serious manufacturer in the technical passport of its products is indicated by the recommended parameter of the length of the tire.
What is fraught with ill.Conceived use of too long or too short tires? You should start with the fact that the size of the tire recommended by the manufacturer cannot be categorically. Smaller size is allowed within reasonable limits, but it is also not recommended: there is an opinion that a short chain provides a lower load on the tool, but it should be remembered that this causes serious harm to the saw headset. The permissible deviation range must be indicated by the manufacturer in the technical documentation attached to the saw.
Long tires of chainsaws give greater convenience when working with a significant material, for example, to perform deep cut in a thick log. However, the use of a long tire paired with a low.Power unit will give one disappointment: the engine power will not be enough to rotate the crankshaft, which means that fast sawing will be simply impossible. The saw process will be slow, gasoline consumption will be increased, the motor will instantly worn out.
The smaller tire length with a properly selected tool of the tool will provide high sawing speed and will be optimal for use in work with small trees or boards.
The length of the saw tire, as a rule, is indicated in inches both foreign and domestic manufacturers. Tires are marked in a 2.Inch step. Below is the equivalent in the familiar to the Russian metric system of lengths:
Buying a tire is not an easy matter
When buying a tire different from the original model, it is likely that the old chain with a new bus does not come together in any way. Ideal! A minor difference, sometimes not even noticeable to the eye, just in one link it can be critical for the entire assembly: the chain will not be dressed at all, or sag.
How to test your chainsaw bar to see if it is worn out
Next point: different chainsaws are designed for different width of the tire grooves, respectively, and leading links are designed for use with different tires. The wide grooves of the chainsaws are invented to withstand significant load loads, which differs in high quality performance and efficiency. When choosing a chain, it is important to cheat with a possible width for this chainsaw model.
A brief resume
Bannered chainsaws, a chain and a carefully chosen bus will allow you to work effectively and calmly, without spending excessive physical and material resources. And it should always be understood that the choice of the components of the gasopying process, including the choice of tire, depend on the type of wood processed, working conditions, professional skills of the master. All this is purely individually and comes with experience.
Not everyone knows how to measure the chainship of the chainship. Chains of chainsaws are available in endless combinations of sizes, types and features. This is due to the fact that the chainsaws themselves differ in size and use. When the time has come to replace the chain, it is especially important to have all the correct information about the chain and its size. Only in this case you can replace it correctly.
The selection of the correct chain to the chainsaws is slightly more complicated than the search for other accessories for the power tool due to the unique method of measuring the chainsaw tire. The information below explains how the chains of the chainsaws are measured, the difference between these dimensions and how to quickly find the measurement numbers necessary to order the correct chain.
The length of the chain of the chainsaw is compared with the measurement of the saw tire. Some manufacturers sell chains for replacing only on the basis of the measured tire. It is important to know that there are no universal chains. A chain with a long tire will require a longer chain accordingly. However, the exact means of determining the length of the chain includes several measurement options, which ultimately affect how well the chain is suitable for your chainsaw.
First of all, it is worth considering the question of how to measure the length of the tire of chainsaw?
- Measure the distance from the tip of the chain saw to the point when the tire first leaves the saw case. Roulette is useful for measuring and obtaining this information. It is necessary to round the measurements to the nearest even number, if the number was not accurate. The resulting number is the measurement of the tire. The most common values of the bar are 16, 18 and 20 inches.
- Lay the chain on a flat surface. Look for the links of the chain, which are sometimes called tips. These links protrude from the lower part of the chain, and they capture the toothed drive, nourishing the chain. Calculate the number of drive links in the chain.
- Determine the height of the chain. Measure the distance between any 3 sequential rivets holding the chain together. Measure from the center of one rivet to the middle of the third link. Rivets are noticeable between drivenings and cutters. Cutting teeth that lie on top of the chain. To find out the height, divide the measurement by 2. A step, along with the number of drive links, describes the length of the tire that is needed when searching for chains for replacement.
The reasons because of which leads away from the rectilinear cut
Sometimes situations arise when it is almost impossible to make a direct cut of a chainsaw, the tire takes away to the left or right. The reason for this behavior of the tool may be as follows:

- Incorrect sharpening of the chain. The teeth of the chain on one side are more worn on the other. Eliminate the malfunction can be sharpened the chain correctly.
- The uneven wear of the links of the chain, the supporting pillows of the links of the chain on one side have a large production, which is why the chain is slightly bending and obtaining a direct cut is no longer possible. You can solve the problem only by replacing the chain.
- And the last, uneven wear. As in the previous case, for this reason, the chain will change the slope and it will not be sawing exactly. It is possible to solve the problem only to replace the tire.
The first parameter is determined by many factors and is usually in red.Ows 30-45 cm, although there are exceptions.
Chain step-the distance that is measured between 3 nearby rivets.
The thickness of the leading links or the height of the groove of the tire can be measured with ordinary calipers. It is usually located in the range of 1.1-2.0 mm.
The total number of cutting links is also taken into account when selecting a chain.
