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 put a chain on a chainsaw correctly?
In most models of the chain, the chain simply put on the tire by unscrewing the head screw, then the links must be placed on the leading star. Before work, the general condition of all cutting surfaces and the guide groove and the installation wheel should be seen. Often, mud and small shavings accumulate in it, which will then lead to planned repair, worsening sliding. Step.By.Step method of work:
- Release the screws fixing the protective cover of the asterisk, usually it is twisted with a lamb nut.
- Turn a stretch asterisk on the right to stop.
- Put the links on the headset, starting from the top. Get to get into proper grooves.
- Fix the fastener of the chain star, tighten the nut. Guides must get into a special gutter.
- Release the chain brake, pull the chain on the mowing fishing line to check the tension. Twist the tensioner lever as needed. Sketch 4. Installing the chain on a chainsaw
The installation wheel should freely scroll after installing the chain of the chainsaw. At the end of the work, be sure to lubricate all the moving elements of the tool in order to avoid re.Wear.
Fundamentally! Installation of a headset should be carried out exclusively in dense protective gloves. This will protect you from injuries and cuts with the sharpened edges of the cutting edge of the teeth.
Tire installation on Stihl and Husqvarna
Models of chainsaws from the manufacturer STIHL I can differ in the assembly process. Step.By.Step control:
- Open the lamb nut, remove the protective cover of the chain star. Turn it on the tire until it stops on the right.
- Put the chain on the tire, starting from the top, the cutting tooth on the upper side should look clearly forward.
- Attach the assembled tire to the chainsaw, pull the design onto the asterisk. Pour the guide on the bolt with a loop. Close the lid, falling with pin into the holes provided by the manufacturer.
- Turn the lamb nut until the time, until the star lid touches the motor body.
- Turn the clamping bolt forward, leading links should get into the grooves of the tire. Twist the lamb nut.
At the end of the work, check the tension if the headset moves poorly, adjust the tension with a nut. Before starting, you should turn on the chain brake.
The tire installation method with a husqvarna saw chain is actually similar. The main difference is that in most models the tension and adjustment of the location of the headset to the body is controlled not by one, but by 2 lamb nuts. A separate adjusting lever is occasionally found on the protective body of the outer sprocket, so the tension setup should only be done with bolts.
Fundamentally! Before working with a chainsaw, you should closely study the user management. It thoroughly outlines all the stages of the option and assembly of the tool.
The chain stretched out
Any multifunctional chain configuration leads to a decrease in the productivity of the tool, injuries during operation.
You should often watch that there is no metal deformation and stretching more than 1 cm.
If such a non.Bond has appeared, you need to purchase the latest chain or adjust the old.
Disconnect the links of the chain on the machine or fix it in a vice, stream rivets with a ratfoll and knock them out with a beard (it is not recommended to use corner grinding).
Delete 1-2 links depending on the degree of stretching of the chain. Then put all the elements in place, stick a rivet and beat it with a hammer, use a special riveting tool. For reliability, it is recommended to use a welding machine. At the end of the work, stream excesses and burrs with a narrow file.
How to understand that it’s time to sharpen a chain
If you do not sharpen the chain on time, this can lead to the following problems:
When sawing a dumb chain, the following things happen:
- Getting a chain in a tree
- Chips have a small size
- A large pressure on the chain is required so that it can saw
- The speed of sawing is low
If there are such signs, then the chain is dull. But besides the presence of these signs, it can also be visually determined whether the chain is dull or not. Just look at the cutting tooth and its edge.
Farm and professional models
Partner and Echo are considered good manufacturers of farm.Type saws. The size of the guides to such saws must necessarily correspond to the power of the unit, otherwise the saw mechanism and the engine will be quickly worn out and the tire of the chainsaw and other details will be required. Recommendations for the choice of guides and their technical characteristics can be read in the instructions of the tool.
Before working with the tool, you need to check the saw headset. If the lubrication of the tire of the chainsaw or minor repairs is required, then you need to do this.
After purchasing a new tool, it needs to be checked. To do this, you need to work at low speeds for about half an hour, and then check the tension of the chain. You need to edit the chain regularly. When working, the tool is heated, and the oil gets to the parts of the saw mechanism in need of lubrication. You can watch the features of the saw on the video.
Each tool detail requires a preventive examination, lubrication and replacement if necessary. We can conclude that the Stihl, Husqvarna and other manufacturers are selected in accordance with the brand and model of the tool. It should clearly approach the saw chain so that the tool serves for a long time and reliably. If you do not comply with the rules of operation of the tool at low temperatures, then soon he will need repairs.
What do you need
Before talking about how to pull the chain of the chainsaw, it is important to designate several simple rules. Firstly, maintenance must be carried out when the engine is turned off and without the risk of its random launch. Secondly, all work is carried out after cooling the tool. The fact is that the hot saw chain has a large length than cold. If you start a stretch, then there will be a risk of tightening and deformation of the tire after cooling.
Remember security! Put on protective gloves so as not to cut your hands with sharp links in the chain.

If the saw set is installed recently and has slight wear, it makes no sense to change the chain. It is enough to adjust its tension. What are the signs of insufficient tension? In the lower part of the tire, the circuit sags, in the upper. It shifts to the side. This leads to a skew during sawing, which means that it affects the service life of the tire. It wears out unevenly. In addition, insufficient tension of the chain increases the risk of its jumping from the tire and is the cause of increased wear of the saw blade and a drive star. Since it is correct to pull the chain of the chainsaw. Does not mean just getting rid of its sagging, it is important not to pull it yet. The difficult course of the canvas in the tire helps to increase the load on the engine and other work nodes of the tool. Try to scroll the chain around the tire with your hand. If this succeeds, it needs to be loosened.
It is important to know! Most often, the tension requires a new chain, since it tends to stretch at the beginning of operation. Constantly check its tension and, if necessary, adjust. So you extend its service life and reduce the wear of other important details of the saw.
Installation of a new chain on the bus
To replace the saw canvas, you should release the tire and remove the old chain. To do this, weaken the fasteners of the lid, which holds the saw set, remove the chain from the asterisk and remove the equipment. The new chain should have the same sizes as the old. It is installed on the tire in the longitudinal groove by leading links. The free end of the chain is attached to the asterisk. Be sure to make sure that along the entire length of the headset the links entered the groove. Install the tire on the pin at the mounting site to the tool. Close this knot with a lid and fix the tire. For this, screws or a rotary regulator are used.
Tip: In order for the tire to wear out evenly, it is recommended to turn it over. Change the upper and lower part. You can navigate by the inscription on the tire. For example, if the letters were located correctly, when replacing the inscription should be upside down.
The instructions for the tool should describe how to pull the chain of the chainsaw correctly. However, there is no way to use it. Therefore, we will talk about the sequence of actions when servicing saws with different types of chain tension.
- Traditional chain tension using a tool. You will need a standard key, which is usually included in the setting set of a chainsaw. On the one hand, he has a working part to unscrew the nuts, and on the other. A slotted screwdriver. First you need to loosen the nuts on the lid, which closes the tire fastening place. Then insert the screwdriver into a special groove and rotate it to stretch the circuit. Do not be zealous. It is better to pull the chain gradually. Make several revolutions. To control the tension with your hands, pulling the chain in the lower part of the tire. After the adjustment is completed, you need to tighten the nuts on the lid.
- Non.Conductive tension of the chain. This method is simpler and faster. On the side of the cover there is a adjusting screw for tensioning the circuit. Rotating it, you control the decrease in the sagging of the chain.
How to understand that the chain of the chainsaw is stretched correctly? It should not sag from below, and when it is delayed, the internal teeth should exit the tire groove by no more than 4. 6 mm. It is important to make sure that the chain is not pulled. To do this, scroll it manually along the tire in the direction of rotation, as when sawing. If the move is light, then you did everything right. It is believed that it is better to almost reach the chain than to pull it. In the process of work, this will be quickly discovered and adjusted. But the difficult course of saw equipment is not immediately noticeable and has a pernicious effect on the engine. Performing the maintenance of the tool with your own hands, you will know how to stretch the chain of the chainsaw without the risk of damage to its working nodes. As soon as you achieve optimal tension, you can fix all the fasteners and turn on the tool. Let him work at idle, without load. Then drown out the engine and make sure that the chain has not flown and did not sag. Such a tool can start working.

The direction of the chain and which side to wear
Chain of the chainsaw, if you carefully examine, has saw teeth directed in one direction. Therefore, the correct direction of saw teeth on the guide tire is very simple to determine: if you place the chainsaw itself in the plane, which it is in the process of operation, then a number of teeth located on top of the guide tire should be directed by sharp edges to the end of the tire. While a number of teeth, which is located below the chainsaw, should look in the opposite direction, towards the leading star.
Put on the chain teeth inward to the grooves in the guide tire will not work, it simply will not stay on the bus. Therefore, wearing a chain of chainsaws on the tire must be so that the guides of the ears of the links of the saw canvas are directed into the guide tire.
The degree of tension of the chain of the chainships affects the functionality of the tool. If the chain headset is slightly stretched, it will fly all the time, perform uneven cuts, if too much. It can break, cause injury to the operator. It is advisable to check the tightening level before each launch, especially if you often work with a chainsaw. Incorrect tension accelerates the wear of important working mechanisms of the tool, forces the engine to work at high speeds.
Not only its working resource depends on the tension of the chain, but also the safety of operation, as well as the service life of the power unit, transmission, other components and mechanisms. The stretch of the chain headset can be performed in two ways. By the way, if there are difficulties in solving the question of how to wear or pull a chain, watch the video instructions.
How to remove a link without using a machine
There are several ways to remove rivets.
- Stiffen. Work carefully, trying not to damage the next, whole link.
- With a corner grinder.
- Cut down with a chisel. To do this, the chain must be squeezed in the vice for the guides, so in order to be able to chop rivets on the connective link.
After the heads of the rivets are worn or cut down, the following actions must be carried out to separate the link. Install the beards between the plates of the connecting angle and a sharp movement to hit it with a hammer. The plates should jump off the rivet body, which passes through them.

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.
It is interesting! The cause of the uneven sawing of a chainsaw may be uneven wear of the link links or their incorrect sharpening. Before replacing the tire, make sure that the chain is working.
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.
