Repair of trimmers Huter (Huter)

When choosing a knife for a mower, you should pay attention to many points. For example, wheels with metal teeth are most often made in the form of a circle. Teeth can differ in shape, species, size. For small trees, as well as thick grass, it is better to give preference to discs with a large number of teeth.

It is worth noting such an advantage of milling circles for motorcycle, such as a quick set of revolutions. However, the high moment of inertia does not affect the drive device of the unit in the best way. For dense mowing, for high, as well as for small rough grass and shrubs, it is better to choose circles with 40 or more teeth and peoration.

Disks with a solid canvas and without holes are distinguished by a large mass, so they should be chosen for powerful trimmers (more than 40 cm3). At the same time, it is convenient for them to mow rare grass, dry, they are also suitable for mowing with different densities.

Winter attacks should be chosen for mowing plants next to obstacles. If you need to mow grass on hay, then you should give preference to steel knives with a large number of teeth with even sharpening. Continuous discs with the number of teeth from 16 to 32 cut plants well with thick stems.

For low.Power trimmers, lobed discs with a minimum moment of inertia are better suited. The smaller the blades, the stronger the tool will grind the grass. So, discs with two blades are most often used to mow homogeneous grass. The main advantage of this species is that it discards cut plants to the side.

When harvesting hay, it is recommended to choose knives with four blades so that the grass does not grind.

The thickness of the blades is also important when choosing. Discs can be stamped or forged. The former are characterized by a low price, but at the same time can be badly damaged, faced with an obstacle. As for the forged discs, chips and slices do not form on them in a collision with solid objects.

For electric trimmers, only plastic knives should be selected. Their low weight will not create an excessive load on the engine. Soft plastic allows the knives when they are on the obstacle do not break, but simply bend slightly or deform. It is recommended to use such cutting elements for beating thick soft grass.

Description of the piston group of the chainsaw of Stihl 180

On the chainsaw of the Stihl 180, the piston group has a diameter of 38 mm. The dimension of the CPH of the chainsaw is determined by the diameter of the piston, the cylinder is slightly larger. In the standard configuration of the CPG MS 180, it is supplied with the piston finger, two piston rings and two stopping.

The inner surface of the cylinder should be perfectly polished and have a glossy shine, which needs to be paid attention to when buying a spare CPG for the Stihl MS chainsaw. If there is damage on the inside of the cylinder, it is not necessary to install such a cylinder

A distinctive feature of the CPG on STIHL MS 180 is that it has two compression rings, while almost all its main competitors have only one. As the manufacturer assures, installing a pair of rings, allows you to better stabilize the piston in operation, strengthen its cooling and increase the compression in the engine, due to which the launch improves.

How to remove a coil from a trimmer for grass and extract a fishing line for a trimmer

Initially, before filling the fishing line for the trimmer to the coil of the trimmer for the grass, it is necessary to extract it from there. Coil or tip is a device that is located inside the braid, bobbin or drum. The heads are of different types (depending on the manufacturers), however, the principle of replacing the fishing line on the coil has the same. First of all, we will figure out how to remove the head from the tool, as well as how to get a drum with a fishing line from it.

It is interesting! The replacement of equipment can be done directly on the tool, but if you do it for the first time, it is still recommended to remove the head, and study the detailed process of winding. After the technology is mastered, you can perform work on replacement on a trimmer of a motorcycle or a gas station.

Instructions on how to promote a hand head on a trimmer, has the following look:

  • Turn the instrument with the head to the top, and if necessary, cleanse it from pollution. Take two fingers of one hand by the cover of the cover (on the mowing head), which are located symmetrically to each other. After a light pressed inward, dismantle the protective cover from the drum
  • Next, from the rampart of the drum, the coil for the fishing line should be removed. It is planted on a shaft without fasteners, so it is dismantled with one hand
  • The main part of the drum is fixed using a screw, which must be twisted with a screwdriver with an appropriate tip or a bat
  • To twist it, it is necessary to hold the base of the drum with one hand, and the second to remove the screwdriver against the direction of the clockwise
  • After that, you can proceed to dismantle. To do this, you do not need to pull it with all your strength, but slightly shaking it, slowly remove it from the hook with a metal shaft on which the drum is planted
  • When installing the installation, the head should be planted in a tetrahedral slot

This process is not difficult, and as you know, it is not necessary to dismantle the entire head if you know how replacement is performed. When dismantling, consider the following nuances:

  • It is recommended to remove the head periodically to prevent the corrosion of the threaded connection. If you never unscrew the screw, then if necessary to do it will be difficult and even sometimes impossible
  • If the screw has a tetrahedral boring of the head, then for twisting you should select a screwdriver or bit of a suitable size to eliminate the licking of the faces on the head
  • When assembling the installation, a threaded seat should be treated with lubricants, for example, solidol or machine oil
  • If the edges on the screw are licked, then for its unscruptions you can use special clamping forceps
  • There are drums that do not require preliminary disassembly. To dismantle them, you should take up it, and rotate in the opposite direction of the direction of the clockwise

Knowing how to disassemble the drum, you should continue to clarify the process of replacing a trimmer fishing line for grass. Below the video shows a detailed process how to open a trimmer coil for grass and disassemble it.

Many companies specially overpay for spare parts for buying new models. For chainsaws and trimmers such as STIHL, spare parts are available in a wider assortment than in Husqvarna. So, choosing a specific model, find out how to handle spare parts.PBT

How to install rings on a two.Stroke self.Scatter piston

However, there is nothing complicated in installing the rings on the piston of a two.Stroke scooter, like a four.Stroke, and many know this. But most of the scooters who have only recently purchased such equipment do not know how to replace the piston with a scooter, how to install rings on the piston, where the arrow on the piston should look, and much more. In this lesson, I will explain how to put the rings on the piston and collect the piston in its place. Since we have already talked about four.Stroke engines, we will only talk about two.Stroke engines. So, our piston is worn out and needs to be replaced.

First of all, rings and piston wear out, and usually they only need to be replaced. With a strong wear of the piston, it is necessary to drill a cylinder. It also opens when the piston wedges into the cylinder, forming deep scratches on the walls of the last. There is nothing wrong with this, and if your new cylinder has passed the correct hole (on which you will need to lay only about 10), you will need a repair kit with new piston rings. Such rings are marked 0.25. The second hole, respectively, 0.5 and t. D. Up to one.

Having bought a piston, you need to collect it. As a rule, you will find the piston itself, two compression rings, the third thin corrugated ring (about its appointment later), a piston finger and two locking rings of the piston.

Now about the third call included. His appointment. Tighten the lower compressed ring to the spring. It is installed under it and, as a rule, is useless during operation. You can throw this ring, or you can put it, it doesn’t matter. Many producers of the piston do not have it at all.

It’s time to put everything in place. Depending on the scooter model, compression rings can be the same or different in thickness and cross section. For example, most pistons for scooters Honda have different rings, where the upper part is thinner, and the lower one has a different cross section.

This should be paid attention to during installation, the top is thinner and sharpened at an angle.

Also pay attention to the inscription on the ring (usually the letter T or the size of the repair), the inscription should always be on top, t.E. On the opposite finger. First you need to put it below, then from above. You do not need to stretch and bend them. These manipulations should be carried out with caution.

The grooves for the rings have locks that prevent the rotation of the rings during operation, so the gap of the rings should be in these locks, otherwise you will not insert the piston into the cylinder.

And the last important point. Arrow (1) at the bottom of the piston or inscription ex. Both the arrow and the inscription should be directed to the exhaust (2). In this case, the ring locks will be located on the side of the valve rod. If you put the locks in the direction of the exhaust, the piston will not last for a long time, the rings in the final window will be delayed and gradually polish it.

For all manipulations with a piston, you need to put a rag in the Carter window so that something does not hit, we still need a crankshaft with bearings.

When installing a piston finger, pay attention to the condition of the separator (bearing), it may be necessary to replace it. Before installing the piston finger, before installing on the piston, install the locking ring on one side (usually on the side where you will uncomfortably inserted your finger and the second stop ring). Then put your finger on the bearing and the second stop ring when it is fixed in the groove, this will give a certain click.

That’s all, now put on the cylinder, not the piston (do not forget to check the condition of the gaskets and grease the walls of the piston and cylinder with motor oil), the cylinder head and alternately tighten the bolts alternately.

If you have any questions when replacing the piston, you can ask them in the Комментарии и мнения владельцев window or on the forum of our site. Good luck in the repair.

Repair of such a level should always be balanced. How to correctly install the rings on the piston of the two.Stroke in the installation of rings on the piston. In such small engines operating at high speeds, the substitution of the 1st piston, which burned out or jammed, gives a long result and, as needed, you need to change the entire piston group. Therefore, you need to think about whether to use this saw further or purchase a new saw.

If this is a professional model, then such a repair should be carried out, but if it is an old household model like Husqvarna 40 and it has worked for more than ten or twelve years, it is unprofitable to repair it. Because its repair will cost, so much. As well as the purchase of a new saw, let not Husqvarna, but on the Partner P350XT Chrome, worth 165 for sure. Over, Husqvarna sells such saws, since Partner is its subsidiary.

Long grass? Long Cords? Cut them out! STIHL FSA 56 Cordless Grass Trimmer | STIHL GB

But if you still decide to repair a chainsaw or a trimmer for grass, then you need original spare parts that are not cheap. With proper operation of the engine, the first repair may not occur soon and only a piston ring or ring will have to be replaced, depending on the model. But if the saw jammed, then you need to change the entire piston group. A cylinder, piston and rings.

It should be noted that the chainsaws of Husqvarna 136/141 have approximately a resource of 500-600 mothers, Husqvarna 340/350. 1000-1200 motorized hours, professional chainsaws of at least 2000-2500 mothers, provided that the instruction manual is strict.

In fact, you can’t rely on these figures, since the real resource can differ significantly both in large and less. But it can be approximately that semi-professional saws work 3-4 times longer than amateur, and professional up to 10 times or more.

Of course, there is nothing eternal, but it is one thing if you change the piston group, after long years of operation and it has worked out my motorcycle chassis, has fully paid for itself, and another thing is that this saw was refined for example, with one gasoline, without oil, and it jammed. Such a saw has to be repaired, since all other details are normal.

Many firms specially overstate the cost of spare parts to buy new models. On chainsaws and trimmers for grass, for example, STIHL, spare parts are in a greater assortment than on Husqvarna. Therefore, choosing a certain model, find out how things are with spare parts.RVT

How to install rings on a two.Stroke scooter piston

How to put a piston correctly

Now about the third ring included. Its purpose is to spring the lower compression ring. It sets it for it actually, and usually does not bear any benefit during operation. You can throw this ring, or you can put it, there is no difference. Many piston manufacturers do not have it at all in the kit.

It’s time to collect everything in place. Depending on the model of scooters, compression rings can be the same or vary in thickness and cross section. Most pistons for Honda scooters, for example, have different rings, where the upper is thinner than the lower and has a different section.

This must be paid attention to when installing, the upper is thinner and stand at an angle.

Also pay attention to the inscription on the ring (usually the letter T or the size of the repair), the inscription should always be on top, that is the opposite from the finger. First you need to put on the bottom, then the upper. In this case, you do not need to stretch them and bend. These manipulations need to be carried out carefully.

There are castles in the grooves for the rings that prevent the rotation of the rings during operation, so the rings gap should be in these locks, otherwise you will not stick the piston in the cylinder.

And the last important point, this is an arrow (1) at the bottom of the piston or the inscription ex. And the arrow and the inscription must be directed towards the exhaust (2). In this case, the locks of the rings will be located from the side of the petal valve. If the locks are in the direction of the exhaust, the piston does not last for a long time, the rings will stretch out into the exhaust window and gradually grind it.

With all the panipulations with the piston, you must put a rag in the crankcase window so that something doesn’t get there inadvertently, we still need a crankshaft with bearings.

When installing a piston finger, pay attention to the condition of the separator (bearing), it may be necessary to replace it. Before installing the piston finger, install the locking ring on one side until the piston is installed (usually on the side where you will not be inconvenient for your finger and the second stop ring). Then put a finger with a bearing and a second stop ring, when fixed in a groove, it will publish a certain click.

So that then you do not have green snot in the wiper that the tuning piston does not climb into the crankcase and you were supposedly deceived here-remove the old piston from the engine and measure the hole for the sleeve with a caliber for the sleeve. If the hole is smaller than the sleeve of the piston, the “meat” of the crankcase allows, the hands grow from where you need it. A round file to help you (only before the boring. Disassemble the engine, collect an empty crankcase for bolts, waste the slopes, make sure that the piston enters the crankcase without problems-wash the details from the chips and collect the engine in a new way. Or in extreme cases, cover the crankcase and file with solidol to somehow protect yourself from the hitting of sawdust into the engine.)

The hole for the 162QMK engine sleeve (such engines are on the Chinese crusts better known among the people as a “watering can”) in the drain is 65 mm. Without boring, this crankcase calmly enters the piston 57mm (150ss), 61mm (1700ss) and 62mm (180ss). You will not find 62mm piston on sale during the day with fire, so it was decided to put the usual piston 61mm on this engine.

By the way, for those who are not in the know, a piston with a diameter of 61mm can easily be installed not only on the engine of the watering can, but also on any other Chinese 150-ok equipped with an engine of the 157qmj series engine. There, if you attach hands, you can stick piston and 62mm, but only if the “meat” of the crankcase allows. Everything is individual, you need to look at the place. In any case, the distance along the studs, which is 61mm piston, which Piston has 62mm. The same.

On the 139QMB series engine from a regular Chinese 80-bit, you can easily install a piston 39mm (45ss), 47mm (72ss), 50mm (84ss)

From left to right: 39mm (45ss), 47mm (72ss), 50mm (84ss)

What will be needed to replace?

For such a procedure, it is worth preparing a set of wrenches, a rattle with end heads, a dynamometric key, a puller for piston rings and a set of rings itself.

The tool for installation/dismantling of piston rings is characterized by a simple design and affordable price. Without this device, the replacement process can turn into an almost impossible task. Of course, earlier car enthusiasts cost a pair of screwdrivers. But it is better to have such a tool, otherwise you can damage the rings or the surface of the piston without it without it. Over, it is always in stock in car shops.
